This unit is preferably designed to be airtight and gas-tight and / or movable relative to the floor (preferably collinear within their perpendiculars). A seal on the floor and / or on the underside of the wall can ensure the necessary tightness. In some embodiments, a circulation device is provided in the chamber. It can be a propeller or comprise such a propeller. In some embodiments, the device according to the invention and / or the method according to the invention does not include a circulation device. In this case, no device for circulating gas, treatment medium, steam, and / or mist is provided in the chamber. In certain embodiments, the circulation device has a rotating segment at its radial end and / or a rotating housing 84J GmbH & Co. KG that surrounds it and / or surrounds it along its circumference.In some embodiments, the circulation device is arranged entirely or partially in a shaft- or cylindrical structure.

In some embodiments, at least one guide funnel or a guide tube is not arranged, or at least largely not arranged, centrally to a circulation device such as a propeller.In some embodiments, several guide funnels and / or guide tubes are located within the chamber. In some embodiments, a guide funnel and / or a guide tube is designed with transverse bores or lateral openings to preferably adapt the flow properties to the process conditions, for example, to smooth the internal cavities of the components or polymer elements, to absorb velocity peaks, and / or to create more uniform flow conditions, such as when the propeller reverses direction to better draw in gas and / or vapor from the treatment medium.In some embodiments, provisions are located at the upper distal end of a guide funnel and / or a guide tube to further modify, accelerate, decelerate, and / or swirl the flows, such as gas flows, for example by means of guide vanes as described herein and / or special nozzle outlets or nozzles, which can also be directed sideways, i.e., toward the chamber wall, and / or downwards, i.e., toward the chamber floor. In certain embodiments, guide funnels, guide covers, and / or guide vanes are designed to direct—preferably at least a relevant amount or a predetermined amount—treatment medium, steam, mist, functionalizing agent, and / or gas, e.g.to be directed specifically into internal regions of elements (for example into the interior of polymer elements in the form of housings) in order to improve, homogenize and / or intensify an inventive treatment and / or smoothing of internal regions and contours. Corresponding guide funnels, guide covers and / or guide plates preferably have provisions such as (further) openings, for example in order to be able to allow inflowing molecules to escape from the interior of the polymer elements and / or to discharge them to the outside. 84J GmbH & Co. KG In some embodiments, guide funnels and / or guide tubes can be actively heated. Appropriate heating devices can be provided. In some embodiments, the device further comprises a magnetic drive for driving the circulation device.In some embodiments, the device, the magnetic drive, the bearing for the circulation device, the frame, and / or the assembly unit are equipped with magnets or permanent magnets. These can preferably withstand temperatures of at least 100°C, preferably of at least 140°C, particularly preferably of at least 160°C, and most preferably of at least 180°C, such as at least 300°C or at least 400°C, permanently or over a longer period of at least one, two, three, or more hours—particularly without, or at least without, significant losses in magnetic field strength. In some embodiments, corresponding magnets made of the neodymium-iron-boron alloy are provided with, preferably, further alloying elements to increase temperature stability, or magnets are formed from the samarium-cobalt (SmCo) alloy, such as Sm2Co17 or SmCo5, or have such elements.In some embodiments, the magnets made of permanent magnetic materials have a Curie temperature above 250°C, preferably above 300°C and particularly preferably above 500°C, such as between 600°C and 900°C. 84J GmbH & Co. KG In some embodiments, the maximum magnetic energy density of the magnet used is above 100 kJ / m³, preferably above 150 kJ / m³ and particularly preferably above 200 kJ / m³. In some embodiments, the device has a control device for operating components of the device. In some embodiments, the control device is programmed to rotate the circulation device once or several times alternately in opposite directions of rotation and / or at different rotational speeds during ongoing treatment of the polymer elements in the chamber.In some embodiments, the device or the chamber has an opening of the chamber or its wall or its floor to an exterior of the chamber. The device can have a valve or other closure device for opening and closing the opening to the exterior. The opening can be provided in addition to the connection for the vacuum or negative pressure device. In some embodiments, the control device is programmed to control the vacuum or negative pressure device, e.g. during an ongoing treatment of the polymer elements in the chamber or while they are still present in the chamber after treatment and the lid has not yet been opened again, for example, to extract air from the interior of the chamber or to create negative pressure in the chamber and 84J GmbH & Co. KG simultaneously, or in an overlapping manner, to actuate the valve for this purpose such that gas or air can flow into the chamber from the exterior via the opening.In some embodiments, at least one device for changing and optimizing the flow direction and / or flow properties is provided in the chamber, in particular configured as a guide plate. In some embodiments, guide plates are to be understood as two-dimensional machine elements, at least in their function. In other words, the mode of action for the targeted and / or predetermined change of the flow properties is based primarily on the two-dimensional projection area of ​​the largest surface of such bodies. The third dimension, i.e. the thickness or depth of such machine elements, is often at least largely negligible in this respect. Guide plates are preferably formed as at least predominantly two-dimensional guide plates from a plate, a sheet and / or a film, preferably with thicknesses between 0.1 mm and 5 mm, more preferably between 0.5 mm and 3 mm, and most preferably between 0.8 mm and 2 mm.In some embodiments, guide vanes are designed and / or described as three-dimensional machine elements, at least in their function. A three-dimensional machine element according to the invention serving as a guide vane can, just like a two-dimensional machine element, be made from an at least predominantly flat workpiece such as a sheet metal, but such a three-dimensional guide vane is preferably bent and / or folded in a third dimension, as 84J GmbH & Co. KG, for example, by at least 5 mm, preferably by at least 10 mm in a third direction. For example, such guide vanes can be folded according to an L- or U-shape in order to at least partially direct the flow in certain directions and / or to generate turbulence. In some embodiments, a guide vane can be formed from a guide body.Guide bodies are preferably manufactured from solid bodies or workpieces and, in terms of flow technology, have at least partially and / or partially comparable properties to three-dimensional guide vanes made of thin-walled bodies that have been formed into a third dimension. In some embodiments, differences in the specific mode of action of such machine elements can arise, for example, due to the greater mass of solid guide bodies and / or due to the identical flow properties of two opposing surfaces of such bodies, for example when the flow direction is reversed by reversing the direction of the circulation device. A greater mass of a guide vane or guide body can, in particular, store a greater amount of thermal energy, which can lead to improvements in the smoothing process.In some embodiments, some or all of the properties and / or advantages disclosed for baffles, such as anodized surfaces, may preferably apply to or be applied to guide bodies. In some embodiments, the mass / surface area ratio of guide bodies and / or baffles may have positive effects on the treatment, particularly with regard to heat storage and heat dissipation, particularly through the selection of suitable materials such as aluminum. In some embodiments, geometric shapes such as triangular prisms or cuboids may be preferred. Other shapes suitable for deflecting flows and / or increasing turbulence may also be used. These are also encompassed by the present invention. In some embodiments, blade-shaped geometries may be used as baffles or guide bodies.They can preferably divert the flow radially from the outside into the center of the chamber and / or preferably generate greater turbulence. In some embodiments, unevenness and / or ribs are provided on the surfaces of the guide vanes or guide bodies. They can serve to specifically generate or intensify turbulence. This increased turbulence can enable a more uniform flow around the components. In some embodiments, at least one guide vane can be attached, preferably at least partially or essentially parallel, or parallel, to the plane of rotation of the propeller or at an acute angle to it, preferably attached to the frame and / or to the receiving device for the polymer elements, for example at a distance of 20 mm to 150 mm from the propeller, preferably between 30 mm and 100 mm. 84J GmbH & Co.KG Such a guide plate can be arranged centrally or at least partially centrally and / or centrically to the axis of rotation of the propeller or can have a lateral offset therefrom, wherein the area or effective area of ​​such a guide plate is preferably more than 25 cm. 2 and especially preferably more than 40 cm 2should be. This can advantageously influence the flow of the propeller. This can lead to a significant change in the flow pattern and promote the formation of turbulent flows. Such a guide plate can be provided with at least one bore, preferably with diameters of at least 20 mm. In some embodiments, at least one guide plate can be mounted at least partially perpendicular to the plane of rotation of the propeller or at an acute angle to it, preferably attached to the frame or to the receiving device for the polymer elements, for example at a distance of 5 mm to 150 mm from the propeller, preferably between 10 mm and 100 mm, wherein such a guide plate can be arranged at least partially centrally and / or centrically to the axis of rotation of the propeller or can have a lateral offset, and wherein the area or effective area of ​​such a guide plate is preferably more than 15 cm 2and especially preferably more than 30 cm 2should be. This can advantageously influence the flow of the propeller. This can lead to a significant change in the flow pattern and promote the formation of turbulent flows. In some embodiments, such a guide plate can preferably be round, elliptical, square or rectangular, or have combinations of these shapes. 84J GmbH & Co. KG In some embodiments, such a guide plate can additionally have internal recesses, such as bores, through holes and / or the like. In some embodiments, the device has at least one heat reactor which has at least one heating device (or heating zone) which is arranged in or on a tube of the heat reactor. The heat reactor can further have a receiving device for the treatment medium in the liquid state or be connected thereto.In some embodiments, the heat reactor is arranged to be located entirely or substantially outside the chamber, and / or such that its interior is or can be brought into fluid communication with the interior of the chamber via an opening in the chamber or its wall or floor. In certain embodiments, the heat reactor is in one piece or has a one-piece housing. This can be made, for example, from a profile tube, e.g., a square one. In some embodiments, the device further comprises a condenser. This can be arranged between the chamber and the vacuum or negative pressure device, e.g., in the negative pressure line or the connection for the vacuum or negative pressure device. In some embodiments, the device further comprises a plurality of heating devices, which can be provided on the lid, floor, and / or wall. 84J GmbH & Co.KG In some embodiments, the device further comprises a magnetic field collector. In some embodiments, the device comprises a removable frame, which optionally comprises the receiving device, e.g. a support, clamping and / or suspension device, for receiving and / or storing the polymer elements inside the chamber. In some embodiments, the frame comprises or is connected to the magnetic field collector, the circulation device and / or the receiving device for the polymer elements to be processed. In some embodiments, the chamber or the device is not in fluid communication with another chamber, in particular not with one from which the treatment medium would be supplied to the chamber in a preheated state, or wherein the chamber is simultaneously the reservoir for the treatment medium. In some embodiments, the method takes place in one chamber, not in multiple chambers.In some embodiments, the method comprises heating the polymer elements to a first temperature in the heating step; evaporating the treatment medium, wherein the vapor of the treatment medium is in particular heated to a second temperature or kept at the second temperature; wherein the treatment medium / vapor heated to the second temperature acts on the polymer elements for a period of time determined by 84J GmbH & Co. KG; wherein allowing the treatment medium and / or its vapor to act on the polymer elements preferably causes a surface of the polymer elements to be at least partially covered with the treatment medium or wetted by it, which is preferably accompanied by a change in the surface properties.It may further comprise the removal of at least a portion of the treatment medium after the specific period of time, wherein the polymer elements are positioned in a closed environment from the start of the tempering of the polymer elements until the completion of the removal of the treatment medium. In some embodiments, gas or air is introduced or admitted into the chamber simultaneously, or in an overlapping manner, during the removal of at least a portion of the treatment medium. In some embodiments, the first temperature is higher than the second temperature. In some embodiments, the assembly unit further comprises a drive shaft arranged to transfer rotational energy or movement from the magnetic field collector to the circulation device. In some embodiments, the assembly unit further comprises a perforated plate as mechanical protection for the circulation device.The perforated plate, alternatively a mesh, can preferably be arranged above the circulation device. In some embodiments, a perforated plate can be designed as a protective grille, fan grille or protective cover. 84J GmbH & Co. KG In some embodiments, the assembly unit further comprises a circumferential segment, e.g. at the radial end of the circulation device. Additionally or alternatively, it comprises a circumferential housing for the circulation device, which surrounds the circulation device or its axis of rotation, completely or partially, e.g. in a shaft- or cylindrical structure, in the circumferential direction. In some embodiments, the device comprises the control device. In some embodiments, the control device is present in or on the device, for example together with other components of the device in a common housing of the device.In some embodiments, the lid or the ceiling or the upper boundary of the chamber is designed to be convex, either entirely or at least in sections, i.e. curved outwards or towards the exterior of the chamber. In this way, should condensate form in the upper region of the chamber, it can flow laterally towards the floor without dripping onto the polymer elements, which is usually disadvantageous. For this purpose, in some embodiments of the chamber, an “anti-drip lid” or another anti-drip element such as an anti-drip surface or a guide lid with the properties and / or advantages discussed herein for the anti-drip lid can be provided. 84J GmbH & Co. KG Such an anti-drip lid or such an anti-drip element can be connected, welded, provided, etc. to the lid of the chamber.In some embodiments, any machine element that is capable of changing, reducing, minimizing, and / or preventing the formation and / or spread of condensate from the treatment medium can be referred to as a drip protection cover. In some embodiments, the drip protection cover is designed such that condensate drops from the treatment medium behave and / or spread in an at least partially or predominantly predetermined and / or controllable manner within the chamber for accommodating polymer elements. In particular, it should be designed such that uncontrolled dripping of condensate from the treatment medium can be suppressed and / or excluded as far as possible. For this purpose, slots or punctures, preferably with a diameter of approx.1 mm width, or other structural changes may be provided in which condensate droplets of the treatment medium settle due to capillary action and remain there for a certain time until they slowly evaporate again and / or until the smoothing process is completed and the treatment medium is sucked away again, for example by means of a pump. In some embodiments, the drip protection cover is designed such that it can at least temporarily store and / or retain the condensate of at least one treatment medium, as explained herein. 84J GmbH & Co. KG In some embodiments, the drip protection cover is optionally designed such that the condensate of the treatment medium can evaporate again as quickly as possible, for example by supplying additional energy such as heat and / or kinetic energy. For this purpose, the drip protection cover can have a heating device and / or an ultrasound device.In some embodiments, the shape, geometry, and / or cross-section of the anti-drip cover is configured such that a flow and / or a gas flow within the chamber is deflected, redirected, and / or optimized, for example by means of flow-optimized geometries. This preferably occurs in such a way that no or fewer condensate droplets of the treatment medium form than without an anti-drip cover and / or that at least some of the condensate droplets that form evaporate more quickly than would be the case without such an anti-drip cover with flow-optimized geometries. In some embodiments, the anti-drip cover is made entirely or partially from at least one metal, at least one plastic, at least one ceramic, and / or glass, or combinations of or with one or more of the aforementioned materials.In some embodiments, in addition to or as an alternative to the selection of the material, the geometry and / or the spatial arrangement, an advantageous surface texture and / or a suitable surface roughness, for example with Ra values ​​of at least 0.5 µm, preferably at least 1 µm, can ensure differences in the formation and / or spread of condensate droplets for the functionality of the drip protection cover. In some embodiments, the drip protection cover advantageously covers at least larger areas, preferably the entire (projection) surface above the polymer elements in its geometric spread. In certain embodiments, the drip protection cover advantageously covers at least 50% or more of the mean or average cross-sectional area of ​​the chamber for accommodating polymer elements.In some embodiments, the chamber, or its wall, is at least largely made of a single material, preferably aluminum or stainless steel.

In some embodiments, the device further comprises at least one circulating device, for example a propeller or rotor, to drive and / or circulate and / or swirl air, gas, treatment medium, its vapor and / or functionalizing agent present within the chamber. In some embodiments, a magnetic drive, for example by means of permanent magnets and / or by means of electromagnetism, can be used for this purpose, for example to transfer the rotary movement of a motor to at least one circulating device. Alternatively, an 84J GmbH & Co.KG circulation device can be operated by means of a mechanical feedthrough, for example, by means of a shaft passing through it, which can preferably be sealed in or on the bottom with elastic sealing elements.

The control device can be programmed accordingly. In some embodiments, the acceleration of the circulating device, such as that of a propeller, 84J GmbH & Co. KG, is advantageously carried out with a strong delay. For example, an acceleration from 0 rpm to the maximum speed can take at least 3 seconds, preferably at least 5 seconds, and most preferably at least 7 seconds. The control device can be programmed accordingly. This is particularly preferable when the circulating device is magnetically driven in order to prevent the magnetic coupling from slipping.In some embodiments, the circulating device, such as a propeller, has between 20 and 60 blades, preferably between 25 and 50, and particularly preferably between 30 and 45 blades. In some embodiments, the rotational speed is changed or varied during the process. In some embodiments, the direction of rotation can have advantages in a first direction, while in other embodiments, the reversed direction of rotation can bring about advantages in the process when the same circulating device is selected. In some embodiments, the direction of rotation of the circulating device is reversed during the process, in some embodiments even several times in succession, wherein the time intervals between times in which the circulating device is rotated in one direction of rotation and times in which the circulating device is rotated in the other direction of rotation can be selected to be the same or different.In some embodiments, the circulating device rotates in one direction for between 15 seconds and 300 seconds, preferably between 30 seconds and 200 seconds, and more preferably between 45 seconds and 150 seconds, until the 84J GmbH & Co. KG direction is reversed. Subsequently or thereafter, it rotates in the opposite direction, preferably between 15 seconds and 300 seconds, preferably between 30 seconds and 200 seconds, and more preferably between 45 seconds and 150 seconds.

The control device can be programmed accordingly.Alternatively or additionally, in some embodiments, the speed can be changed during the process, for example continuously or alternatingly. In certain embodiments, the at least one of the existing circulation devices can be operated at least temporarily at speeds between 5000 rpm and 50,000 rpm. In some embodiments, the direction of the annular flow or the generated movement of the gaseous or vaporous treatment medium corresponds to the direction of rotation of the circulation device. In other words, the circulation device can generate a movement of the air, vapor and / or gas molecules in the region of the wall inside the chamber, which in some embodiments is helical, preferably rapidly increasing, i.e. with a 84J GmbH & Co.KG high gradient, and has the same direction of rotation as the circulating device, preferably regardless of the axial flow direction of the circulating device, i.e. regardless of whether the circulating device accelerates the molecules upwards or downwards. In some embodiments, devices for changing the flow direction and / or the flow properties are provided within the chamber, with which the air, steam, gas and / or particle flows, for example of at least one treatment medium and / or a functionalizing agent, can be influenced or changed in a targeted and / or measurable manner, preferably in predetermined combinations with the effect of the at least one circulating device on the flow and / or the shape and size of the inner wall and / or the prevailing pressure and / or the prevailing temperature in the chamber. Such devices, which e.g.The air and / or gas guide plates disclosed herein can be formed from machine elements. They can be suitable for changing and / or deflecting air and / or gas flows and / or particle flows or nanoparticle flows, for example by means of bionic surfaces (shark skin) on the inner wall, projections on the inner wall, pins, foils, tubes, guide plates, baffles, perforated plates and / or plates, wherein these are preferably arranged at least predominantly transversely to the flow direction or the main flow direction. In some embodiments, at least one 84J GmbH & Co.KG Gas flow specific machine element for the controllable and / or predeterminable flow guidance and / or flow manipulation of gas, vapor, mist and / or solid particles such as powder, fibers or nanoparticles, and / or machine elements such as a cover, e.g. the guide cover, are modified so that advantageous flow conditions are found. In some embodiments, at least one such device is attached to a removable assembly unit according to the invention, for example as described for Fig. 13.

It can be designed to allow a smaller amount of air, gas, mist and / or particle flow from the immediate area of ​​the lid directly towards the polymer elements. Such a machine element as a guide lid, which can for example be convexly curved towards the lid, can preferably separate and / or allow flow of molecular and / or particle movements above and below this machine element depending on the flow velocity. Such a machine element can act as an at least partially acting separation barrier between 84J GmbH & Co.KG lid and polymer elements serve and, with some polymer materials and / or geometries of the polymer elements, such as large surfaces and / or polymer elements with pronounced cavities or internal contours, provide advantages during treatment. For example, the amount of treatment medium vapor and / or mist flowing or acting at least predominantly from above can be reduced and, accordingly, at least a relatively greater amount of treatment medium vapor and / or mist can act more intensively from below and / or from the sides. In some embodiments, the orientation of the surfaces of such machine elements is at least partially and / or partially parallel to or at a substantially constant distance from the lid and / or the floor of the chamber.In some embodiments, the distances of such machine elements from the inner wall, preferably from the lid, at least of the predominant region or the predominant area are approximately between 5 mm and 120 mm, preferably between 8 mm and 80 mm, and particularly preferably between 10 mm and 60 mm, such as between 12 mm and 40 mm or between 20 mm and 60 mm.

In some embodiments, at least one such machine element, hereinafter also referred to as a guide cover, is located in the immediate vicinity of the cover, wherein they have largely the same central axis as the cover and / or the wall of the chamber for accommodating polymer elements and / or such central axes are at least largely parallel.In some embodiments, two, three, four or more guide covers are located in the immediate area of ​​the cover, wherein the guide covers can be geometrically identical or at least approximately identical and / or guide covers can differ in their shape, for example by different diameters, different heights, different material thicknesses, different materials, different flat surfaces, different bevels, different arcs, different radii and / or different surfaces including surface coatings.In some embodiments, the smallest distance between the inside of the cover and the (nearest) guide cover can be less than 100 mm, preferably less than 50 mm, more preferably less than 30 mm, and most preferably less than 20 mm, such as between 4 mm and 20 mm or between 4 mm and 14 mm, whereby optional fastening elements such as three, four or five fastening screws with or without spacer sleeves between the inside of the cover and the guide cover should not be taken into account with regard to the distances. In some embodiments, the guide cover has no axial distance from the cover at least at one point or in one area, but is in direct contact with it on the inside of the cover, for example for better 84J GmbH & Co. KG heat transfer from the inside of the cover to the guide cover.In some embodiments, the geometry of the cover, at least on the inside of the chamber, is designed such that it at least partially corresponds to a guide cover in terms of shape and / or mode of operation and / or flow guidance.

This serves to ensure that thermal radiation can be absorbed particularly well, for example in order to be able to optimally introduce thermal energy through a heat radiator arranged outside the chamber. In some embodiments, at least one guide cover has, at least in large areas, different temperatures than the cover and / or at least the inside of the cover and / or the wall and / or the base, for example by approximately 1°C to 20°C higher, preferably by approximately 2°C to 10°C higher.In some embodiments, at least one guide cover has, at least in areas, in predominant parts or completely, surfaces with an Ra value of less than 0.5 µm, preferably of less than 0.25 µm and particularly preferably of less than 0.15 µm.

Preferably, drainage on the underside of the at least one guide cover facing away from the cover is relevant for this. In some embodiments, at least parts of at least one guide cover are curved. Such bends and / or edges are preferably directed or shaped upwards, i.e. oriented towards the cover. In certain embodiments, at least parts of at least one guide cover are provided with at least one bead. In some embodiments, at least one guide cover forms, e.g., radially extending, contours or geometries at its outer end or at several outer ends, which functionally represent a channel or at least partially a channel.In this way, dripping of condensed treatment medium at these locations can be prevented, avoided, reduced and / or relocated to other locations by means of the channel-like structure. 84J GmbH & Co. KG In some embodiments, at least parts of at least one guide cover are formed from a plate, a sheet and / or a film. In some embodiments, at least one guide cover has geometries that exert capillary effects on the condensate of a treatment medium, particularly preferably at elevated temperatures, such as at temperatures above 70°C, preferably above 100°C and particularly preferably above 149°C. The capillary structures, which can be provided for this purpose, thus absorb condensate and can therefore be regarded as temporary storage.In some embodiments, at least one guide cover has surfaces which preferably exert strong capillary effects on the condensate of at least one treatment medium, particularly preferably at elevated temperatures, such as at temperatures above 70°C, preferably above 100°C and particularly preferably above 149°C. In some embodiments, at least parts of at least one guide cover are provided with recesses, bores and / or slots, the spacing, lengths, widths and / or diameters of which are selected such that increased capillary forces act on the condensate of a treatment medium and / or on drops thereof and in this way the condensate or drops thereof can be drained away and / or collected in a controlled manner from the surface and / or the underside of the guide cover.In some embodiments, at least one guide cover can consist of several parts, whereby individual parts of such a guide cover, considered on their own, can also be understood as a guide cover in other 84J GmbH & Co. KG embodiments. In other words, a guide cover can be joined from two or more guide covers to form a guide cover that is coherent according to the invention and which, for the person skilled in the art, preferably achieves the object of the invention as a coherent machine element. In some embodiments, at least one guide cover does not have a drip protection surface or is shaped or configured in a corresponding manner that would protect elements from dripping, in particular not by special shapes or geometries that would promote the drainage of the treatment medium condensate.In some embodiments, preventing or reducing the dripping of the treatment medium condensate from the underside of a guide cover in the immediate vicinity of the elements is at least predominantly, largely or completely not determined and / or exerted, reduced and / or intensified by the geometry and / or shape of such a cover, but rather occurs at least to the relevant extents by the selection of preferred surface properties, such as surface treatments by sandblasting and / or coatings, such as anodizing. In some embodiments, a guide cover can have at least one drip protection surface. In some embodiments, a guide cover can have at least two drip protection surfaces. A first drip protection surface is arranged opposite the cover, i.e. directed upwards. A first drip protection surface is preferably formed by the upper side of the 84J GmbH & Co. KG guide cover.The guide cover forms a second drip protection surface on its underside in order to at least largely reduce condensation of the treatment medium and / or to prevent condensate droplets from forming and dripping uncontrollably onto elements. In some embodiments, a guide cover ensures controlled and / or predetermined dripping of condensate from the treatment medium. In some embodiments, a guide cover has one or exactly one point or exactly one area at which condensed treatment medium can drip. In some embodiments, a guide cover has two points or areas at which condensed treatment medium can drip. These can be designed as predetermined drip points. In some embodiments, a guide cover has multiple points or areas at which condensed treatment medium can drip.In some embodiments, a guide lid is designed such that no treatment medium condensate can and / or does drip off. In some embodiments, the condensate of a treatment medium can run off or flow off via the inner wall, wherein in this way the treatment medium preferably evaporates again on the heated wall before it reaches the floor. 84J GmbH & Co. KG In some embodiments, the condensate of a treatment medium can run off or flow off via the receiving device for the polymer elements or the frame for receiving, clamping and / or hanging polymer elements, wherein such running off or flowing off preferably originates at least partially in the center of the chamber. In some embodiments, the lid is designed, for example, conical, recessed, funnel-like, bead-like, cup-like or similarly towards the center.It thus promotes the pooling of the treatment medium condensate, which would then drip out of the recess in a targeted manner. Dripping can occur where no polymer elements are present. Drainage can be provided, e.g., along a rod, along a pipe or a channel, along the receiving device where it does not come into contact with polymer elements, etc. In some embodiments, at least one guide cover is designed such that drops of treatment medium condensate do not drip downward in a controlled or uncontrolled manner, but rather that the condensate can be retained and / or stored at least temporarily in and / or on the cover.In some embodiments, a guide cover has a diameter and / or a diagonal of between 100 mm and 500 mm in its peripheral region or at least in predominant regions, preferably between 150 mm and 450 mm, particularly preferably between 150 mm and 300 mm, and very particularly preferably between 180 mm and 280 mm, such as between 200 mm and 270 mm. 84J GmbH & Co. KG In some embodiments, a guide cover can have a height of at least 10 mm, preferably at least 12 mm, particularly preferably at least 15 mm, such as between 15 mm and 50 mm.It was discovered by chance that special surface structures created by dedicated surface treatment processes, such as blasting with glass beads and / or other blasting media and / or vibratory grinding and / or laser structuring and / or coating, can lead to altered surface tensions, preferably in the hot treatment medium condensate on the hot cover, and that drainage is thus possible and / or improved even with draft angles and / or gradients of less than 15°, preferably less than 10°, and very particularly less than 8°. This makes drainage from relatively flat draft angles and / or relatively flat gradients possible where, according to the state of the art, drainage of condensate droplets from the treatment medium on the underside would not yet be possible.This offers the advantage, for example, that a guide cover with a lower overall height can be used, thus losing less usable chamber volume for the polymer elements than with the prior art, for example, with a relatively pronounced (steep) dome or a pronounced roof slope. Guide covers, drip protection covers, lids, frames, holding devices for polymer elements, and / or other structural components of the device can be provided with the special surface structures described here. 84J GmbH & Co. KG In some embodiments, advantageous configurations and / or advantageous properties of guide covers can apply to guide plates, and vice versa.In some embodiments, the lid is designed at least on its inside or at least in regions of its inside, for example due to its shape and / or its surface properties, such that its function at least partially corresponds to that of a guide lid, in particular as described herein. In some embodiments, the lid is designed at least on its inside or at least in regions of its inside, for example due to its shape and / or its surface properties, such that its function at least partially corresponds to that of an anti-drip lid, in particular as described herein. In some embodiments, the lid is designed on its inside, for example due to its shape, such that its function does not correspond to that of an anti-drip lid, in particular as described herein. In some embodiments, the term “lid” can be replaced with the term “guide lid”.In certain embodiments, the "lid" and the "baffle lid" are different structures. In some embodiments, the term "lid" can be interchanged with the term "drip protection lid," in others it cannot. 84J GmbH & Co. KG In certain embodiments, the "lid" and the "drip protection lid" are different structures. In some embodiments, the term "baffle lid" can be interchanged with the term "drip protection lid," in others it cannot. In certain embodiments, the "lid" and the "drip protection lid" are different structures.Any device designed to specifically modify the air, vapor, and / or gas flows and / or the flows of functionalizing agents within the chamber, primarily in the region of the inner wall and / or the polymer elements, and / or to modify them in process-relevant ratios, is considered, in some embodiments, to be such a device for modifying the flow direction and / or flow properties. In other embodiments, these are only those devices that are specifically and / or exclusively intended to modify the flow as described.Process-relevant changes in air and / or gas flows triggered by devices according to the invention can be assessed, for example, by treating and / or smoothing two identical polymer elements or, preferably, two identical polymer element groups in the same spatial arrangement within the chamber using exactly the same treatment media, parameters, and settings, once in a chamber with and once in a chamber without devices for modifying the flow and / or flow properties. 84J GmbH & Co. KG can then compare these polymer elements and / or polymer element groups in detail.If, for example, different treatment results and / or different roughness values ​​are observed on internal contours or surfaces between two identically treated elements, this can be attributed to the altered flow properties caused by the devices for modifying the flow properties. In preferred embodiments, devices for modifying the flow properties within the chamber result in an improvement in treatment and / or smoothing with lower Ra values, for example, with the effect of better and more evenly smoothed surfaces of the polymer elements, for example, on internal contours by a lower Ra value of 1, preferably 2, and particularly preferably 3.In some embodiments, the circulation device is designed such that it can execute or achieve an ascending flow direction from the bottom to the lid, preferably in the immediate vicinity of the wall of the chamber, preferably in the form of an at least predominantly laminar flow.

Due to, for example, a spiral or helical flow, the at least one medium within the chamber experiences 84J GmbH & Co.KG on the way from bottom to top has a longer contact time on or in the immediate area of ​​the inner wall and can thus have more heat energy transferred on its way.

Fig. 1 shows the device 100 according to the invention in a first exemplary embodiment. The device 100 comprises a chamber 1, which is intended and / or suitable for receiving the polymer elements P to be treated. The chamber 1 has a lateral wall 3, a bottom 5 and an opening, preferably at the front or top. As can be seen from Fig. 1, the front or top opening is optionally the only opening of the chamber. The opening can be closed by means of a cover 7, preferably in a fluid-tight manner, wherein the cover 7 can optionally have at least one further passage, as explained below for the example shown here. The chamber 1 has an internal volume or capacity of preferably lessthan 100 l, preferably less than 60 l, particularly preferably less than 40 l. 84J GmbH & Co. KG An optional receiving device 9a for storing the polymer elements P is arranged inside the chamber 1. The base 5 optionally has a base section 5a. In the lid 7, alternatively on the side wall 3 or in the base 5, a connection for a vacuum line 17 for a vacuum or vacuum device is optionally arranged. The arrangement of the connection in the example of Fig. 1 is purely exemplary, but preferably the arrangement of such a connection is located in the upper section of the chamber 1. The device 100 optionally further comprises a circulation device 21, here for example in the form of a propeller or rotor. The circulation device 21 is driven by a motor 25 via a drive shaft 25a. The drive shaft 25a is guided through the base 5 by means of a shaft feedthrough 28. Fig. 1 shows the inventiveControl device 200. For reference numerals shown in the figures but not specifically discussed herein, reference is made to the list of reference numerals, which is hereby incorporated. Fig. 2 shows the device 100 according to the invention in a further exemplary embodiment. Reference is made to the explanations for Fig. 1 and the differences from Fig. 1 are discussed below to avoid repetition. 84J GmbH & Co. KG The drive of the circulation device 21, which here as optionally in any other embodiment disclosed herein can be or have a propeller, as described herein, is carried out magnetically in the example of Fig. 2. The motor 25 moves or rotates at least one permanent magnet 27 below the base 5 (preferably tapered or thinner at this point). The magnetic field of the rotating permanent magnet 27 acts contactlessly on ferromagnetic metal 29 (or generally ferromagnetic material, e.g. plastics with bondedIron powder, etc.), which is indirectly connected to the circulation device 21 and thus transmits the rotation thereto. Fig. 2 also shows optional air baffles 40, which serve to effectively direct the fluid flow generated by the circulation device 21 within the chamber 1, in particular to ensure or guarantee uniform temperature control of the interior of the chamber 1 and / or to at least partially thermally and / or fluidically separate the area above the optional air baffles 40 from the lower area within the chamber 1. In the example of Fig. 2, a cooler 33 is optionally arranged on the vacuum line 17, which is preferably located upstream of the vacuum device or pump (not shown). In a simple embodiment, such a cooler 33 can be designed as a piece of pipe or hose in order to effect or intensify condensation of the treatment medium in this area. 84J GmbH &Co. KG To seal the interior of the chamber 1 from its exterior, the lid 7 in the example of Fig. 2 has a seal 31 on its underside, i.e. on the side which, during use, faces the upper end face of the wall 3 of the chamber 1, for example an O-ring, e.g. made of fluororubber (FKM), perfluororubber (FFKM) or silicone. The sealing can be achieved differently in other embodiments, for example by means of a seal such as a U-profile on the upper end face of the wall 3 of the chamber 1, for example made of silicone. Fig. 2a shows the device according to the invention of Fig. 2 in an alternative embodiment. Fig. 3 shows the device 100 according to the invention in a third exemplary embodiment. To heat the chamber 1 or for the heating step a) of the method according to the invention (see Fig. 8), a heating mat is provided in the present example as the first heating device 11, which provides the chamber 1 with at leastlargely over its entire circumference and / or a heating cord with which the chamber 1 is wound, preferably as evenly as possible. In alternative embodiments, it can be provided to arrange one or more heating mats around the circumference of the chamber 1, or sections thereof, and / or to wind several heating cords, preferably helically, around the chamber. In the example of Fig. 3, the receiving device 50 for the treatment medium B is provided partly outside and partly inside the chamber 1, in which the polymer elements P are arranged. In the exemplary embodiment shown, it extends through a defined recess through the chamber floor. In other embodiments, the recess can alternatively or additionally be provided in the wall 3 and / or the lid 7 of the chamber 1. Such a recess can be a, in particular circular, through-opening, which is opposite the receiving device 50for the treatment medium B can have at least one sealing element, for example in the form of an O-ring. Alternatively or additionally, the receiving device 50 for the treatment medium B can have a flange as a sealing element or can be provided with a labyrinth seal. In some embodiments, the receiving device 50 can also be permanently connected to the chamber 1, for example by welding or gluing. In a circular configuration, the through-opening can, in some embodiments, have a thread in or on its circumference, so that in this way a receiving device 50 for the treatment medium B or a corresponding housing 71 thereof, which is provided with an external thread, can be screwed into the thread of the through-opening. As indicated in Fig. 3, in some embodiments, the area or part of the receiving device 50 for a treatment medium B, which is outside the chamber 1 forReceiving polymer elements is designed to be significantly larger than the area or part of the receiving device 50 which extends within the chamber 1, for example by an order of magnitude or 84J GmbH & Co. KG by a volume with a factor of 2 to 50. In this way, the receiving device 50 for the treatment medium B or a housing 71 thereof can be designed to be so large in its length and thus have an internal volume that a larger amount of vapor of the treatment medium B can be formed and stored even before it is introduced into the chamber 1, without the usable volume of the chamber 1 for the polymer elements P being excessively restricted. The part of the receiving device 50 for the treatment medium B, which is optionally located within the chamber 1, can be equipped with at least one controllable or adjustable machine element, here for example a needle valve 70. In this way, at a predeterminedAt a given time, (exactly) predetermined amounts of the treatment medium B and / or its vapor are introduced into the chamber 1 to the polymer elements P. The needle valve 70 can, in certain embodiments, be manipulated, for example, by means of a mechanical feedthrough from areas outside the container and outside the chamber, such as, for example, by a rotating and / or sliding rod with at least one seal, such as, for example, an O-ring. This is not shown in Fig. 3, however. In some embodiments, the needle valve 70 can be replaced or supplemented by other closure systems, such as, for example, a solenoid valve. In some embodiments, the needle valve 70 can be replaced or supplemented by a self-regulating pressure valve. The (vapor) pressure at which such a pressure valve (independently) opens (and possibly closes again) can be adjustable in certain 84J GmbH & Co. KG embodiments, for example, by rotating and pre-tensioning aCompression spring. In some embodiments, no section or part of the receiving device 50 for the treatment medium B protrudes into the interior of the chamber 1. In some embodiments, the receiving device 50 for the treatment medium B does not have a closure system such as a needle valve, preferably at the upper distal end and / or in or in the region of the chamber 1. In such embodiments, the chamber 1 and the receiving device 50 are fluidically connected during all method steps, at least during method steps a) and b). In some embodiments, the receiving device 50 is completely or at least partially designed as a heat reactor and / or has at least approximately comparable process patterns and / or is suitable or prepared for corresponding processes. Fig. 4 shows the device 100 according to the invention in a fourth exemplary embodiment. Fig. 5 shows a receiving device 50 for theTreatment medium B, as it can be arranged in a chamber 1 of the device 100 according to the invention. Fig. 6 shows the device 100 according to the invention of Fig. 3 with an alternative, external arrangement of the receiving device 50 for the treatment medium B. This is arranged completely outside the chamber 1 with the polymer elements P. In this way, the temperature of the receiving device 50 for the treatment medium B can be controlled or regulated more independently of the temperature of the chamber 1 with the polymer elements P. This can, for example, have the advantage of a higher temperature gradient between the chamber 1 and the receiving device 50 for the treatment medium B and / or a simplified, external accessibility of the receiving device 50 for the treatment medium B, in particular in order to be able to heat it better. With the complete spatial separation of the receiving device 50 for the treatment medium B and the chamber 1 for thePolymer elements, these or their respective interiors are operatively connected, in particular fluidically connected, by suitable machine elements. In the example of Fig. 6, this machine element is a connecting line 72. This can be, for example, a pipe (of any cross-section) or a hose. If at least one surface of the receiving device 50 for the treatment medium B borders on at least one surface of the chamber 1 or if these are in a direct mechanical connection (e.g., by screwing, pressing, gluing, or the like), as can be provided in alternative embodiments, the machine element can be dispensed with or realized by a simple passage. In certain embodiments, at least one intermediate machine element can be provided within the fluidic connection between the receiving device 50 84J GmbH & Co. KG for the treatment medium B and the chamber 1 with the polymer elements P, whichcauses a temporary closing or opening of this connection. This can be a valve, analogous to the description of the embodiment in Fig. 3. In some embodiments, an intermediate machine element such as a throttle or an orifice can cause an at least temporary tapering of at least one cross-section of the fluidic connection, such as a tapering of the cross-section by up to 90%, preferably up to 95%, and particularly preferably up to 99%. Fig. 7 shows the second heating device 12 on the right in a further embodiment as a heat reactor 90, which is arranged below the floor 5 of the chamber 1 (chamber not shown in Fig. 7). The example in Fig. 7 shows a heat reactor 90, optionally as a round, long, hollow tube 91 (of any desired, constant or varying cross-section), for example made of chrome-plated brass, which is filled with heat-conducting granules, for example silicon spheres and / or with at least one inlay such as 91b,see e.g. Fig. 15b, can be filled or have this. For example, a second heating device 12, here in the form of a heating sleeve, is arranged at the top or elsewhere on this tube 91. The interior of the tube 91 is in fluid communication with the chamber 1. The receiving device 50 for the treatment medium B is arranged at the bottom of this tube 91 and is fluidly connected to it. In the example of Fig. 7, it is surrounded by a further, 84J GmbH & Co. KG optional, third heating device 12', here also in the form of a heating sleeve, which can alternatively be provided at a different point on the tube 51 or the heat reactor 90. The chamber 1, in which the polymer elements P are arranged, can now be (pre)heated to a predetermined temperature, e.g. to 155°C, e.g. B. over a period of approximately 45 minutes. Since the treatment medium B is spatially relatively far away from the heating chamber 1, the treatment medium B heats up only insignificantly,in particular not to its boiling point. The device 100 according to the invention or its chamber 1 is evacuated, for example by applying a negative pressure of approximately 0.5 bar or approximately 0.25 bar, for example by means of the negative pressure line 17 (see, for example, Fig. 7a). The upper second heating device 12 is heated to a higher temperature, e.g., approximately 170°C to 210°C. This also heats the tube 91 and with it the heat-conducting granules optionally located therein and / or the at least one inlay 91b optionally also included. If the third heating device 12' is now switched on, for example, to approximately 160°C to 200°C, the treatment medium B is heated and begins to boil within a certain time, depending on the heating power used and the treatment media used (e.g., at approximately 0.5 bar internal pressure). In the example of Fig. 7, between the outer diameter of the pipe 91 and the optionally significantly larger nominal diameter 84J GmbH & Co. KG theA sleeve adapter 93 – or one such adapter in each case – in the form of a metal element, for example, a tube or thick-walled tube, for example, made of aluminum, is inserted between the heating devices 12, 12' in order to transfer the heat better and more evenly to the tube 91 of the fluid connection. The sleeve adapter 93 has, for example, a material thickness of more than 3 mm, for example, a material thickness of more than 5 mm. The optional sleeve adapter 93 between the tube 91 and one or all of the heating devices 12, 12' has, for example, a length that is greater than the length of the respective heating device 12, 12'; in the example of the upper heating device, it is at least twice as long as this. The treatment medium B evaporates when heated by the heating device 12', referred to herein as the third, and rises upwards. It is further heated by the heat reactor 90 (in the example mentioned here, up to 180°C or up to 200°C) untilIt flows into the treatment chamber 1. On the left in Fig. 7, a further receiving device 50 for the treatment medium B is shown. This can correspond to one of the embodiments mentioned herein, for example, the embodiment of Fig. 5. The further, optional receiving device 50 can, for example, be a capsule as shown, or also another heat reactor. The further receiving device 50 and the heat reactor 90 can be connected or used simultaneously or sequentially. 84J GmbH & Co. KG The example in Fig. 7 further shows an optional tapering of the base 5, i.e., a section of the base 5 that has a smaller thickness than adjacent sections of the base 5, which is designed here as a circular pocket. Such a circular pocket can, for example, have a diameter of 20 mm to 200 mm, particularly preferably a diameter of 50 mm to 120 mm, such as 70 mm to 100 mm, and preferably a depth of 0.5 mm to 20 mm.particularly preferably from 1 mm to 10 mm, such as 3 mm to 6 mm. The wall thickness in the region of such a circular pocket is therefore preferably from 1 mm to 10 mm, particularly preferably from 2 mm to 8 mm, such as 3 mm to 6 mm. Fig. 7a shows the heating device for a device according to the invention in a further embodiment in a sectional view, also designed as a heat reactor 90. Particular reference is made to the description of Fig. 7. Clearly visible in the illustration of Fig. 7a is the treatment medium B, which in this embodiment is in liquid form in the receiving device 50 for the treatment medium B, which is arranged at the bottom of the tube 91 and is fluidically connected thereto. The tube 91 can also be filled with heat-conducting granules and / or an inlay such as an inlay 91b in the example of Fig. 7a; this has been omitted from the sectional view for the purpose of better clarity. 84J GmbH & Co. KG Fig. 7b shows the heating device of theFig. 7a is supplemented by an optional fourth heating device 12'', which is also part of the heat reactor 90 or in contact with it. In this embodiment, the heat reactor 90 thus has not one, not two (as in other embodiments), but three heating devices along a path for the treatment medium B or its vapor. In Fig. 7b, they are all connected to or part of the pipe 91 of the heat reactor 90. Detached from the heat reactor 90 or its fourth heating device 12'', the embodiment of Fig. 7b has a valve 95 arranged to open or close an opening of the chamber 1 to an exterior thereof, e.g., the atmosphere or a gas reservoir. The valve 95 is only one example of a device for establishing or permitting a fluid connection or for preventing a fluid connection between the chamber 1 and another space or the environment. A shut-off valve, a throttle, etc. (in short:Shut-off device) are also encompassed by the present invention. The valve 95, or the shut-off device, can be arranged in a line 97 in any embodiment, as shown in Fig. 7b. Alternatively, it can be part of the base. The valve 95 or the shut-off device can be opened to reduce or compensate for the negative pressure that occasionally prevails in the chamber 1 by inflowing gas such as the ambient air, for example during the transition to process step c), or up to approximately 15 seconds before or after. The valve 95 can be variable in its fluidic cross-section, preferably continuously. It can be controlled or regulated to change its cross-section. A corresponding control of the valve 95 or the shut-off device can be provided, and the control device of the device 100 can be programmed accordingly. Fig. 7c shows the device 100 according to the invention for the treatment ofPolymer elements P in a further embodiment. Reference is made to the description of Fig. 7b to avoid repetition. In the following, only the differences to Fig. 7b will be discussed. In the example of Fig. 7c, a further line 17a branches off from the vacuum line 17, which can be opened or closed by means of a further valve 95a. This line 17a can serve as a bypass line and, for example, at least promote condensation of treatment medium in process step c) by allowing air or gas with preferably colder temperatures to be supplied there. The line 17a can lead to an outside, for example to the atmosphere, in connection with an air or gas reservoir, etc. From the bottom of the capsule 50 for the treatment medium B or of the heat reactor 90, a further line 17b optionally branches off, which can optionally be opened or closed with a further valve 95b. By means of this line 17b, if the valve95b is opened, for example, after the treatment (see process steps a) to c)) excess treatment medium B or after a 84J GmbH & Co. KG functionalization step (process step d)) functionalizing agent can be removed and optionally recycled. The valves 95a and 95b can be opened or closed manually or automatically and / or their fluidic cross-sections can be preferably continuously varied. The control device can effect this. In some embodiments, the valve 95 for introducing air and / or gas into the chamber has a cross-sectional area of ​​at least 1 mm², preferably of at least 3 mm² and particularly preferably of at least 5 mm², such as between 6 mm² and 10 mm². In some embodiments, the valve 95 for introducing air and / or gas into the chamber has a cross-sectional area or adjustable cross-sectional area that differs from the cross-sectional area or adjustable cross-sectional area of ​​the valve 95a,which is arranged in the line 17a, which branches off from the vacuum line 17, in a ratio between 100:1 and 2:1, preferably between 50:1 and 5:1, most preferably between 30:1 and 5:1. Fig. 8 shows the sequence of a method according to the invention for the treatment of polymer elements P in an exemplary embodiment. Here, the polymer elements P have been obtained by an additive manufacturing process. Reference is made to the description and the reference numerals of Figs. 1 to 5. 84J GmbH & Co. KG Process step S1 represents the provision of a device 100 according to the invention. S2 represents the provision of the polymer elements P to be treated in the chamber 1 of the device 100, for example in or on the receiving device 9. In process step S3, the preferably vaporous treatment medium B is distributed freely in the chamber 1. For this purpose, it is heated in process step S3, e.g. in aor several heat reactor(s) 90. Alternatively, liquid treatment medium B is provided in the chamber 1, preferably freely, i.e., on the bottom section 5a and / or in the bead 15. Alternatively, the treatment medium B can have been introduced into the chamber 1 beforehand and usually in liquid form and have distributed, for example, on the bottom section 5a or in the bead 15. Process step a) represents the heating step for heating the polymer elements P in the chamber 1 using the first heating device 11 or only the first heating device 11. In process step b), which represents the evaporation step, the treatment medium B in the chamber 1 is evaporated by means of the second heating device 12, or only the second heating device 12. After reaching the vapor state, the second heating device 12 is throttled orswitched off. 84J GmbH & Co. KG The use of the vacuum device, see the vacuum line 17, can contribute to achieving the vapor state. It can also be controlled or regulated, preferably automatically, by the control device. The latter can also apply to the circulation device 21. Finally, a cooling step for cooling the polymer elements P can optionally be included in the process according to the invention, shown here as process step c). In this step, the treatment medium B will condense and can be collected on the base section 5a and / or in the bead 15 and kept ready for reuse. Fig. 9 shows a device 100 according to the invention for treating polymer elements P in a further embodiment with a perspective obliquely from below. For better clarity, the surrounding walls 3 and the lid 7 of the chamber 1 are not shown. Reference is made to the description of the preceding figures.in particular to the description of Fig. 7 and Fig. 7a. By way of example, as is also possible in any other embodiment, two heat reactors 90 are provided. More than two heat reactors 90 can be provided, e.g. three, four or more. In the example in Fig. 9, the heat reactors 90 are optionally also round, long, hollow tubes 91, for example made of 84J GmbH & Co. KG coated aluminum, which can be filled with inlays, such as one or more inlays 91b. For example, they are arranged below the chamber 1 (not shown in Fig. 9) or below the floor 5 of the chamber 1. The heating devices discussed above are arranged on the two tubes 91, here e.g. in the form of a heating sleeve. The interior of the tubes 91 is in fluid communication with the chamber 1. In some embodiments, further (first) heating devices, for example inThe heating elements 12, 12', 12'' can be arranged in the form of additional tubes or at least one heating cord and / or at least one heating mat on the periphery of the wall, as described herein. First and / or second heating devices can be controlled by means of temperature sensors, such as thermocouples, preferably in the immediate vicinity of the heating devices (contact measurement) and inside the chamber (air or gas temperature). The power of each of these heating devices 12, 12', 12'' can, for example, be approximately 200 watts to 1000 watts; the total power of all heating devices should preferably be between 1000 watts and 3500 watts. Different values ​​can also be achieved. A receiving device 50 for the treatment medium B (not shown in Fig. 9) can be arranged in or on at least one of the tubes 91 and fluidically connected to it or these. Heating devices 12, 12', 12'' can, in particular, be provided further down on the tubes 91. 84J GmbH & Co. KG InIn this context, reference is again made to the description of Fig. 7. In the example of Fig. 9, a sleeve adapter 93 in the form of a metal element, for example a tube or thick-walled tube, for example made of aluminum, is inserted between the outer diameter of the tube 91 and the significantly larger nominal diameter of the heating device 12, 12' in order to transfer the heat better and more evenly to the tube 91 of the fluid connection. Optionally, provision can be made for preheating the heat reactor(s) 90. In this case, for example, a second heating device 12, such as a heating sleeve, of the heat reactor 90 in an upper section thereof and / or a third heating device 12' of the heat reactor 90 in a lower section thereof (see Fig. 7) and / or possibly further heating devices on the heat reactors 90 can be used to heat the heat reactor 90 preferably to a temperature between 30°C and 150°C, preferablybetween 60°C and 100°C, for example to approximately 80°C. Optional preheating can be advantageous to ensure optimal repeatability with different cooling times between processes, which can result in different residual heat within the various machine elements, such as, for example, a sometimes greatly varying residual heat from the heat reactor 90. In the example in Fig. 9, as in any other embodiments, two permanent magnets 27 can be seen, for example, which are arranged above a heat sink 19. Above the permanent magnets 27, in the floor 5 of the chamber 1, a further thermal insulation 53' can be seen, which serves in particular to protect the permanent magnets 27 from the heat radiation from the floor 5 of the chamber 1. The magnetic drive 23, which in the example of Fig. 9 comprises the permanent magnets 27 and a ferromagnetic metal 29 (see Fig. 9a), serves to drivea circulation device 21, in the present example a propeller with a rotating segment 26 (omitted in Fig. 9a), driven by a drive shaft 21a. The design of the circulation device 21 is purely exemplary and not to be understood as limiting. Various designs thereof are described in more detail in Fig. 10ff. In some embodiments, the drive shaft 21a has a surface, a tip, a flattened tip, a rounded tip, an arcuate shape, or a spherical shape at a distal end for its driving and / or its mounting. This distal end is preferably designed as an axial bearing 57 (see Fig. 13) for supporting the tensile forces of the magnetic forces of the magnetic drive 23, wherein the counterpart of the bearing is preferably formed by a machine element made of a material that preferably has low to very low friction values ​​and / or that can withstand the operating temperatures within the chamber 1, such asfor example, PEEK or special high-temperature dry sliding plastics. In some embodiments, the spherical shape is achieved by joining a sphere or at least a spherical section, such as a hemisphere, to the drive shaft 21a, wherein a sphere is preferably formed from a hard or hardened metal, a glass, or a ceramic. The number of circulation devices 21 in the example of Fig. 9 is purely exemplary and not to be understood as limiting. Several circulation devices 21 within the chamber 1 are also encompassed by the present invention. If several circulation devices 21 are present inside the chamber 1, they can be switched on or off simultaneously or sequentially. The control device can be programmed accordingly. The at least one circulation device 21 is operated at a speed of preferably 100 rpm to 3000 rpm, particularly preferably between 500 rpm and 1500 rpm, such as approximately 1200rpm. This serves to generate a type of circulating air heating inside the chamber 1 and thus to heat the polymer elements P to the most uniform target temperature possible, preferably for a period of up to 180 minutes, particularly preferably up to 60 minutes, such as for a period of 10 minutes to 45 minutes. The at least one circulation device 21 can, in certain embodiments, change its speed and / or direction of rotation. The control device can be programmed accordingly. This can advantageously ensure an optimized distribution of the treatment medium B. For example, at intervals of 60 seconds to 120 seconds, the direction of rotation of, for example, at least one of the optional propellers of the circulation device 21 can be reversed. 84J GmbH & Co. KG Above the propeller of the circulation device 21, a perforated plate 20 can be seen in Fig. 9 as mechanical protection for the circulation device 21. The design as a perforated plate is purelyby way of example; any other mechanical protection is also encompassed by the present invention. Fig. 9a shows the device 100 from Fig. 9, viewed obliquely from above, with a view of the perforated plate 20. Particular reference is made to the description of Fig. 9 in order to avoid repetition. In a modification of Fig. 9, Fig. 9a shows another possible form of the circulation device 21. Clearly visible in the illustration in Fig. 9a is a ferromagnetic metal 29, which forms the magnetic field pickup of the magnetic drive 23 or is encompassed by it. Likewise visible in the floor 5 of the chamber 1 are the openings or outlet openings of the heat reactors 90 for the treatment medium B, by means of which the pipes 91 are fluidically connected to the chamber 1 (not shown in Fig. 9a) and through which the treatment medium B enters the chamber 1. Fig. 9b shows a schematic representation of the magnetic drive 23 of the circulation device 21 from the previous figures. InIn some embodiments, the circulation device 21 and / or the swirling device is driven via a magnetic drive 23 without a mechanical connection thereto. 84J GmbH & Co. KG A magnetic drive 23 can be formed by means of one or more permanent magnets 27, attached or incorporated on / in a rotatable machine element 27a outside the chamber 1, and at least one ferromagnetic magnetic field collector 29 of the magnetic field within the chamber. The rotatable machine element can be made of magnetic stainless steel or be or have a coated machine element made of steel. The rotatable machine element for receiving magnets is preferably formed from a non-ferromagnetic material, such as aluminum or a polymer material. In some embodiments, the rotatable machine element 27a for receiving the magnets is connected to a drive or motor 25, whereinThermal devices, such as at least one cylindrical heat sink 19 (see, for example, Fig. 9) with cooling fins, can preferably be attached to the machine element and the motor, and such devices can preferably be forced ventilated, for example by an axial fan. In some embodiments, a permanent magnet, such as a neodymium magnet, is provided. In the example of Fig. 9b, two permanent magnets 27 are arranged in the rotatable machine element 27a; in still other embodiments, three or more permanent magnets can be provided. With more than one permanent magnet, in preferred embodiments, the poles (north / south) are installed and / or aligned in opposite directions. The 84J GmbH & Co. KG magnets are preferably circular or square and can preferably have diameters, diagonals and / or edge lengths between 10 mm and 40 mm, particularly preferably between 15 mm and 30 mm, such as between15 mm and 25 mm and at heights between 4 mm and 30 mm, preferably between 6 mm and 15 mm and particularly preferably between 8 mm and 12 mm. In some embodiments, the permanent magnets 27 or the part of the magnetic drive 23 located outside the chamber are arranged to be thermally insulated from the hot floor 5, the hot wall 3 and / or the hot lid 7 of the chamber 1 by at least one thermal insulation 53'. Thermal insulation can be or comprise, for example, a foil or a preferably thin plate. It can preferably be arranged between the permanent magnets 27 and the preferably metallic housing of the chamber 1, such as the aluminum floor 5. In some embodiments, several thermal insulations of the same or different design and / or thickness can be provided, preferably made of materials or comprising materials that at least do not significantly impede the magnetic flux into the interior of the chamber.influence or interfere. Such materials can be, for example, ceramic, glass, mica and / or a polymer or comprise such materials, such as a Kapton film or a mica plate, wherein the material thicknesses are preferably between 0.05 mm and 2 mm and particularly preferably between 0.1 mm and 1 mm. 84J GmbH & Co. KG In some embodiments, a film or a thin plate is arranged on the base plate, the cover or the wall by additional devices in such a way that, at least over a certain area, distances are created which can form an additional, thermally insulating air, gas or vacuum barrier, wherein such distances can be, at least in sections, preferably between 0.05 mm and 5 mm, particularly preferably between 0.2 mm and 2.5 mm, such as between 0.5 and 1.5 mm. For example, as in the example of Fig. 9b, a spacer element 54, such as aA small PEEK ring with a height between 0.4 mm and 1.3 mm may be introduced. If the thermal insulation 53' is preferably held down or tensioned at its edge region or along its edge region and / or its circumference by mechanical devices, such as a stainless steel ring, while at least one spacer element is located therebetween, for example directed towards the chamber floor, then the deformation of the thermal insulation 53' forms a thermally insulating cavity which increases in thickness towards the center and can preferably assume a dimension between 0.2 mm and 1.2 mm in the average thickness. Fig. 10 shows the exemplary embodiment of the circulation device 21 of Fig. 9 and Fig. 9a obliquely from above. In some embodiments, the device 100 according to the invention can be configured with one, two or more circulation devices 21, for example propellers, fans, and / or swirling devices.84J GmbH & Co. KG The circulation device 21 can be designed and arranged to cause turbulence, e.g., by means of the optional propeller. One, two or more circulation devices 21 can be arranged, mounted, or supported on or in the region of the bottom 5 of the chamber 1 and / or the lid 7 of the chamber 1 or and / or the wall 3 of the chamber 1. In certain embodiments, the at least one circulation device 21 is arranged in a central region (in the vertical direction) of the chamber 1 in its interior, such as in or near the center of the chamber and / or in the region of the polymer elements P to be treated and / or between the polymer elements P, wherein a rotary drive for the circulation device 21 is provided in the form of a long drive shaft 21a or axle, with or without additional bearings such as radial bearings, ball bearings, or plain bearings. The drive shaft 21a or axle can be a flexible shaftThe drive for this can be said magnetic drive 23 or the motor 25, which in turn drives it. In some embodiments, several circulation devices 21, in particular several propellers, with the same and / or different geometry are mounted on the same drive shaft 21a, for example at an axial distance between 10 mm and 100 mm. In some embodiments, the at least one circulation device 21 is arranged at a preferably axial distance between 10 mm and 200 mm from the wall, preferably from the floor 5 84J GmbH & Co. KG, preferably at a distance between 20 mm and 120 mm, particularly preferably between 30 mm and 100 mm, such as for example between 40 mm and 80 mm. In some embodiments, the at least one circulation device 21 has an outer diameter between 50 mm and 350 mm, preferably between 75 mm and 250 mm, particularly preferably between 90 mm and 200 mm, most preferably between 120 mm and 180 mm, such asfor example, between 140 mm and 160 mm. The circulation device 21 in the example of Fig. 10 corresponds, for example, to that in Fig. 9, namely in the form of a propeller 21 with a segment 26 circumferentially extending along the end sections of the radially extending propeller elements or blades 22 constituting the propeller 21, which segment radially delimits the mostly uniformly shaped blades 22. This configuration is purely exemplary and not to be understood as limiting. In some embodiments, the geometry of the blades 22 may be different from that shown in Fig. 10, such as alternately changing blade geometries, preferably in an arrangement with dynamic balancing. In the example of Fig. 10, the circulation device 21 has 30 blades 22. The number of blades is again purely exemplary and not to be understood as limiting. Thus, in some embodiments, a circulation device 21 may have between 2 and 100 blades 22.preferably between 5 and 70, particularly preferably between 10 and 50, such as between 15 and 35 blades 22. In some 84J GmbH & Co. KG embodiments, a circulation device 21 can be referred to as a multi-blade device. The blades 22 of the circulation device 21 have preferred angles compared to a flat surface, wherein the flat surface is determined by a perpendicular, which simultaneously represents the axis of rotation around which the circulation device 21 rotates. In some embodiments, at least partial ranges of such angles can be, preferably measured in the outer circumferential region, between 20° and 65°, preferably between 25° and 60°, such as between 27° and 53°. In the example in Fig. 10, the surfaces of the blades 22 of the circulation device 21 are at least partially straight or flat; in others, they can be concave or convex. The height of the circulation device 21 is between 5 mm and 100 mm, preferably between 8 mm and 70 mm,particularly preferably between 10 mm and 50 mm, such as between 15 mm and 35 mm. In some embodiments, the circulation device 21 is at least partially manufactured by additive manufacturing, preferably by a light-induced process such as SLA or a powder bed process such as SLS or MJF and / or preferably from a material that contains at least one polymer, a metal and / or a ceramic. In some embodiments, the circulation device 21 can be formed at least in part from polyamide (PA), polypropylene (PP), 84J GmbH & Co. KG polyketone (PK), polybutylene terephthalate (PBT), PPS, PEI, PPSU, PEEK, PEAK, PEK, PEKK, PFA, PTFE, a UV resin such as an acrylate, or mixtures thereof, with or without fiber reinforcement. In some embodiments, the circulation device 21 consists at least predominantly or completely of aluminum. In some embodiments, the circulation device 21 is subjected to aSubjected to post-processing, such as smoothing and / or functionalization, such as a coating with metal or a fluoropolymer coating. As can be clearly seen in the example of Fig. 10, the circulation device 21 has at least one positive driver connection 24 in its center. Such a driver connection 24 can be designed, for example, as a wrench flat, square, or polygonal connection. In some embodiments, the circulation device 21 can be axially screwed onto a drive shaft 21a; in others, it is plugged in, for example, with a quick-connection mechanism, such as an axial snap-in closure. In some embodiments, two or more circulation devices 21 can be mounted on the same drive shaft 21a, preferably having an axial distance from one another, which can be approximately between 2 mm and 100 mm or even more, preferably between 5 mm and 50 mm, particularly preferablybetween 10 mm and 30 mm. 84J GmbH & Co. KG In some embodiments, two or more circulation devices 21 are alternatively or additionally mounted on different shafts and / or are driven by different drive units or drive motors. In the example in Fig. 10, the circulation device 21 has a circumferential segment 26 in the outer region of the circumference, here with an at least partially circular design. Such a partial region of the circulation device 21, particularly preferably in the outermost circumference, can be designed, for example, in the form of a cylinder or tube section which has a diameter between 80 mm and 300 mm, preferably between 100 mm and 250 mm, particularly preferably between 120 mm and 200 mm and a wall thickness between 0.5 mm and 4 mm, preferably between 0.8 mm and 2.5 mm, particularly preferably between 1 mm and 2 mm. The height of the surrounding (circular) segment 26, which preferably forms the outer circumference of theIn some embodiments, the diameter of the circulating device can be between 5 mm and 150 mm, preferably between 8 mm and 80 mm, and particularly preferably between 12 mm and 50 mm. In the embodiments of Fig. 10, the circumferential, circular segment is preferably formed symmetrically in the axial direction on the circumference of the circulating device 21. In other embodiments, it is asymmetrical, for example formed at least predominantly only in one axial direction, viewed from the plane of the outer blade tips. An asymmetrical design can be installed within the chamber in both directions, i.e., the 84J GmbH & Co. KG circular segment directed towards the inner wall, as well as vice versa. The segment 26 can serve to effect a flow through the chamber 1 in an axial or vertical (relative to the figures) direction, less in a radial or horizontal (relative to the figures) direction. As shown in the following figures, the segment 26be supplemented or replaced by a circumferential housing 26' (see Fig. 11), which in cooperation with the circulation device 21 can achieve a similar effect. Fig. 10a shows a further exemplary embodiment of the circulation device 21 from an oblique view above. Reference is made to the explanations for Fig. 10. The embodiment of the circulation device 21 essentially corresponds to the embodiment in Fig. 10. The circumferential segment 26 has been omitted. It can be clearly seen here that the blades 22 have an essentially rectangular shape. Fig. 10b shows a further exemplary embodiment of the circulation device 21 from an oblique view above. Reference is made to the explanations for Fig. 10 and Fig. 10a. In contrast to Fig. 10a, in this embodiment the blades 22 have a slightly curved outer contour, similar to a knife edge. 84J GmbH & Co. KG Fig. 10c shows a further exemplary embodiment of the circulation device 21 from an oblique top view; u Itreference is made to the explanations for Fig. 10, Fig. 10a and Fig. 10b. The design of the circulation device 21 essentially corresponds to the design of Fig. 10. In contrast to Fig. 10, the vanes 22 in the embodiment of Fig. 10c project beyond the lower edge of the circumferential segment 26. Fig. 10d shows a further exemplary embodiment of the circulation device 21 from above. Reference is made to the explanations for Fig. 10 to Fig. 10c. The design of the circulation device 21 essentially corresponds to the design of Fig. 10. In contrast to Fig. 10, the circulation device 21 in the embodiment of Fig. 10c has a second set of vanes 22a which is distributed on the outside of the circumferential segment 26 and has a different angle than the vanes 22 which are closer to the center of the circulation device 21. The number of inner wings 22 may correspond to the number of outer wings 22a, as in the example of Fig.10d, but does not have to be. 84J GmbH & Co. KG Fig. 11 shows the arrangement of a circulation device 21 in a device according to the invention in a further embodiment with a perspective obliquely from above. Reference is made to the explanations regarding the preceding figures. In the example of Fig. 11, the circulation device 21 is surrounded by a circumferential housing 26'. The housing 26' has a non-planar structure on its end faces, by means of which the flow within the chamber 1 can be influenced. The treatment medium B or its vapor flows out of the heat reactor through the opening in the bottom 5 of the chamber 1. This is indicated by two small black arrows. Due to the rotation of the circulation device 21, which is represented by a circular, black arrow pointing counterclockwise, a flow initially forms in the chamber 1, predominantly obliquely downwards and radially outwards, which flows from the chamber bottom 5 in a preferably laminar flowfurther radially outwards, is distributed relatively evenly in all directions and continues to move evenly upwards along the wall 3 in a predominantly laminar, helical flow, whereby the molecular flow can be further heated during contact or in the immediate vicinity of the base 5 and the wall 3. In the example of Fig. 11, the flow of the treatment medium B is further diverted by means of guide vanes 97 arranged inside the chamber 1. Due to the at least partial impact of the 84J GmbH & Co. KG flow on the guide vanes 97 and the simultaneous strong deflection thereof, local turbulences arise, which convert previously predominantly laminar flows into at least partially or predominantly turbulent flows, depending, among other things, on the flow velocity. In this way, it is ensured that polymer elements P, which are arranged further inside the chamber (not shown here, but in the process approximately in the shownsectional plane during the process), also at least partially come into contact with the treatment medium vapor B with swirling and turbulent flows. The arrangement in the example of Fig. 11 serves to distribute the treatment medium B in the chamber 1 evenly and preferably turbulently in the interior of the chamber 1. Everything stated herein regarding the treatment medium can, in some embodiments, also apply to a functionalizing agent in a functionalization step. Fig. 12 shows an embodiment of a guide plate 97. Reference is made to the explanations for Fig. 11. A flow (white block arrows) impacts a section of the guide plate, which is optionally inclined at 45° thereto and projects into the interior of a chamber 1 (not shown in Fig. 12). It can be seen from Fig. 12 that the effective height Z` for the flow, which the depicted guide plate effectively opposes to the molecular flow, is only the projected height Z` in the direction of theFlow is. At the angle of 45° shown here, the effective height Z` corresponds at least approximately to approximately 71% (sin 45°) of the actual height 84J GmbH & Co. KG Z. Since in this example the effective width Y` corresponds to the actual width Y, the process-relevant surface X is also approximately 71% of the actual area of ​​the baffle. Baffles 97, for example as shown in Fig. 12, should preferably be arranged transversely to the flow direction and preferably attached or inserted in the immediate area of ​​the inner wall, such as in the immediate area of ​​the wall, the cover and / or the bottom. Baffles 97 can primarily be designed to trigger local turbulences in the flow, so that at least predominantly or partially laminar flows are converted into turbulent and / or at least predominantly or partially turbulent flows. Baffles 97 can be arranged in the center of the chamber, for example between, aboveand / or under the polymer elements. Guide plates 97 can be provided at least partially adjacent to the inner wall; in other embodiments, they form a distance of between 5 mm and 40 mm from the inner wall, preferably between 8 mm and 30 mm, at least in large parts. Fig. 13 shows the arrangement of a circulation device 21 inside a chamber 1 (not shown in Fig. 13) of an apparatus according to the invention for treating polymer elements with polymer elements P. 84J GmbH & Co. KG arranged above it. Reference is made to the explanations regarding the preceding figures to avoid repetition. From bottom to top, the following components can be seen in the example in Fig. 13: - a magnetic field collector 29 made of ferromagnetic metal with drive shaft 21a; - a circulation device 21 with a rotating segment 26, which is connected to the magnetic field collector 29 by means of the drive shaft 21; - a perforated plate 20 as mechanical protection of theCirculation device 21; and - a frame 9 for setting up on the floor 5, for its fixation on the floor 5 or on another section of the chamber 1 (not shown in Fig. 13) in, on, or on which the polymer elements P to be treated can be arranged or suspended. - Optionally, guide plates 97 of different shapes and non-symmetrical arrangement are screwed to the frame 9, one of which is at least partially designed in the form of a perforated plate. In some embodiments, no guide plate is attached to the frame 9. - An optional guide cover 97a is screwed to the top of the frame 9. The guide cover here has, for example, two circular recesses or circular pockets. In other embodiments, more or fewer recesses can be present on the guide cover 97a 84J GmbH & Co. KG, in still other embodiments, no recesses are present at all. In preferred embodiments, no guide cover 97a is present. In someIn some embodiments, these components together form an assembly unit 10 according to the invention, which can be designed as a device that can be removed from the chamber 1. It can be provided that it is positioned for treatment, preferably oriented towards markings, locking points and / or cavities, at a predefined position within the chamber 1, whereby for some embodiments there can also be several such defined positions, depending on the application. In some embodiments, the chamber 1 can be used for different treatments, smoothing and / or functionalizations with one or more assembly units 10, which can have the same interfaces to the chamber 1 (basic dimensions, locking points and magnetic field pickup 29), but can differ from one another in other aspects, such as in the design of the circulation device 21 and / or the frame 9 for receiving polymer elements P, for example, in order topreferably a few large polymer elements P or at other times several smaller polymer elements P can be suspended or clamped. Particularly preferably, different devices for changing the flow directions and / or flow properties, such as guide plates 97 as an example here, can be attached, e.g. on the frame 9, in the lower, middle and / or upper area, for example with different shapes and / or surfaces and / or at (very) different positions and / or in different numbers. Such arrangements of, for example, guide plates 97, baffles and / or perforated plates can preferably be individually configured for the treatment of specific combinations of the materials from which the polymer elements 97 are formed and the treatment media B used. In this way, it can be ensured that the user is provided with different assembly units 10 and thus exactly one for the specific material andThe method allows for the optimal design of the device or chamber in just a few simple steps. For example, for the combination of propylene glycol as treatment medium B with polymer elements P made of polyamide 12, a different arrangement of such assembly units 10 as just described may be necessary than, for example, for the combination of polypropylene (PP) with the treatment medium B 3-methoxy-3-methyl-1-butanol acetate (MMB-Ac), or for example the combination of polymer elements P made of polyketone (PK) with the treatment medium B benzyl alcohol. The present invention thus also relates to a set comprising a device 100 according to the invention with at least two mutually different assembly units 10 according to the invention. In some embodiments, such an assembly unit 10 is provided, for example, on the frame 9 and / or at 84J GmbH & Co. KG other location(s) with numbering and / or coding and / or at least one chip such as an RFID chip.provided so that the control device 200 of the device 100, preferably using sensors, automatically recognizes the currently inserted assembly unit 10 and selects, executes, and / or stores the corresponding programs and / or parameters. Such sensors can be part of the device 100. Example 1 A device as shown in Fig. 7b, with only one heat reactor 90, was used to treat polymer elements P made of PA12, which were obtained by an MJF process (Hewlett-Packard). The four elements all had a surface roughness of approximately Ra = 9; Rz = 50, and the surfaces were gray in color. Approximately 35 ml of propylene glycol was introduced into the heat reactor 90 as treatment medium B, whereby the exact amount is preferably not directly critical for the treatment. The polymer elements P were attached within the chamber 1 to the designated receiving devices 9a for polymer elements P, without them interfering with one another.touched. The lid 7 was closed, and a vacuum of approximately 800 hPa (approximately 0.8 bar) absolute pressure was generated by the vacuum pump via the vacuum line 17. A propeller, arranged as a circulating device 21 at the bottom inside chamber 1, with a diameter of 150 mm, was switched on, rotating counterclockwise (as viewed from above) at a speed of 1200 rpm, so that the flow direction pointed upwards. The direction of rotation and the speeds were changed several times during the further course of the treatment by 84J GmbH & Co. KG. The first heating devices 11 on the bottom 5, on the lid 7, and on the wall 3 of chamber 1 were switched on, and a control device regulated the temperature inside the chamber to approximately 165°C. During the heating described, about 5 minutes before reaching the mean chamber temperature of about 165°C, a second and a fourth heating device 12 and 12'' respectively on the heat reactor 90 were switched on simultaneously, whereby the tube 91was heated at least initially to approximately 155°C to 180°C, while at a relatively simultaneous time the negative pressure in chamber 1 was reduced to approximately 0.2 bar absolute pressure using the vacuum pump. Subsequently, by switching on the third heating device 12', the treatment medium B, propylene glycol, was heated to approximately 145°C to 155°C and evaporated. As it rose in the heat reactor, it was further heated to approximately 157°C to 164°C and then distributed within the chamber for approximately 5 minutes until all heating devices on the heat reactor were switched off again. The exact temperature and the exact amount of vapor were not exactly determined, but the initial temperature of the vapor could change due to the changing amount of liquid, initially 35 ml of propylene glycol, among other things, due to the evaporation enthalpy, and not the entire amount of propylene glycol evaporated, but a previously not exactly determinable residue remained in the heat reactor, however, subsequently with approximately6 ml of residual propylene glycol was calculated. The propylene glycol vapor spread solely through the supplied heat without any further intervention, for example, without opening a valve, optionally valve 95, and was further set in motion by the circulation device 21, whereby the vapor pressure within the chamber rose to approximately 0.7 bar to 0.8 bar absolute pressure. After 3 minutes, all heating devices 11 were switched off and the 84J GmbH & Co. KG vacuum pump switched on to pump vapor out of chamber 1, thus stopping the smoothing process. At the same time, valve 95 for ventilation on the chamber with a valve bore of approximately 3.3 mm was opened to supply at least approximately the same amount of air to chamber 1 as was extracted by the vacuum pump, and in this way the pressure within chamber 1 could be maintained at least approximately at approximately 0.8 bar during the pumping process of approximately 10 minutes. The lid was then removed.opened, the polymer elements P were removed and dried for 2 hours in a vacuum oven at 90 °C. The resulting polymer elements P were smooth and black and had clear contours. The edges were sharp and not rounded, the surfaces were smooth, without grooves and / or elevations, and mechanically strong. The roughness could be significantly reduced, so that the roughness of the elements after treatment averaged Ra = 1.9 and Rz = 14. Example 2 The treatment of elements made of PA12 (MJF) was carried out with the same values ​​and settings as described in Example 1. Instead of propylene glycol, 30 ml of 3-methyl-1,3-butanediol was used as the treatment medium. The treatment medium B was fed from the treatment agent reservoir 101 via a pump 105 to chamber 1 according to the circulation system 300 and, after treatment, was discharged and recovered as described for Fig. 16. A diaphragm pump was used as an example for84J GmbH & Co. KG is used to generate the negative pressure required for treatment and to remove / extract gaseous treatment medium B at the end of the smoothing process. A condenser 33 (upstream of the vacuum pump) is installed between the vacuum pump and chamber 1, as is optionally provided in the present invention. During the removal / extraction of the vaporous treatment medium B, it could condense within the condenser 33 and flow into the collection tank 103 via gravity. No large quantities of gaseous (or condensed) treatment medium B could be detected at the fluid outlet of the vacuum pump to the atmosphere, as the condenser 33 could condense large quantities of the treatment medium B, and this collected in the collection tank 103. Approximately 70% of the treatment medium B could be recovered in the collection tank 103, which was subsequently pumped back into the treatment medium storage tank 101 by means of a pump 109.The resulting polymer elements P were smooth and black and had clear contours. The roughness of the elements was measured after treatment with Ra = 1.7 and Rz = 13. With further tests with adjustments of temperatures and times, a necessary treatment temperature of at least 130°C was determined for 3-methyl-1,3-butanediol for the treatment of PA12; preferably, at least 140°C and particularly preferably at least 145°C, such as between 147°C and 167°C or between 149°C and 164°C, was applied. Fig. 14 shows an embodiment of a heat reactor 90 according to the invention in an exploded view or in a disassembled state. 84J GmbH & Co. KG In the example of Fig. 14, the heat reactor 90 is designed to be dismantled, for example, it can be opened without tools in order to fill in treatment medium B, whereby the filling in the present example is done by means of a capsule 50, which can be designed as a disposable cartridge. In alternativeIn some embodiments, the heat reactor 90 cannot be opened for refilling with treatment medium B, but is filled with treatment medium B through the upper end and / or through a filling area provided for this purpose, preferably in a predefined amount.

Fig. 17 shows a bearing 99 for the circulation device 21 in a further embodiment of the device according to the invention, here preferably with a magnetic drive. The bearing 99 can, as shown by way of example in Fig. 17, in some embodiments be understood as a frame or a stand in or on which the circulation device 21 is received or supported. The bearing 99 can thus in turn have struts, supports, feet, etc. Reference is made to the description and the reference numerals of the preceding figures. The circulation device 21, here in the form of a propeller, rests rotatably on the bearing 99 for the circulation device 21, which can simultaneously serve as the base for the frame 9 with the receiving device 9a for the polymer elements P (not shown in Fig. 17). Its drive shaft 25a is preferably equipped with a magnetic field pickup 29a,which in turn has an integrated 84J GmbH & Co. KG induction sensor, fixedly connected so that it can be carried along by it. In the floor 5 of the chamber 1, optional induction sensors 110 are positioned, preferably in such a way that they can interact with the induction sensors of the magnetic field pickup 29a for driving the circulation device 21. In some embodiments, the speeds and / or directions of rotation of the preferably magnetically driven circulation device 21 within the chamber 1 can be measured and / or controlled accordingly by means of the induction sensors 110 and the induction sensors. In this way, reliable and reproducible speeds of the circulation device 21 can be achieved, e.g., depending on the respective internal temperature of the chamber 1, the treatment medium used and / or the currently prevailing steam pressure. Above the circulation device 21 on the bearing 99 for the circulation device 21, a perforated plate or amechanical protection 20 is arranged for these. In the example of Fig. 17, this protection 20 has the form of a protective grid. Fig. 18 shows a nozzle outlet 96 of a heat reactor 90 in a further embodiment of the device 100 according to the invention.

Fig. 24 shows a part of a cover 7 of a device 100 according to the invention in a further embodiment, which simultaneously also fulfills the function of a guide cover 97a, in a sectional view from below. In the example of Fig. 24, the cover 7 has a draft angle of 7.5° on its inside or underside – preferably all around. The draft angle can be configured in one of the angular ranges mentioned herein, e.g., between 3° and 10° (see above). The shape of this embodiment can be manufactured particularly easily, for example, by machining it from an aluminum plate, e.g., a 20 mm aluminum plate (20 mm thick), e.g., by turning it out.or milled out (e.g., using a 5-axis milling machine). The cover 7 preferably has a diameter of approximately 300 mm and a thickness of 20 mm. The size and material thickness are preferably selected so that the cover 7 can withstand the (vacuum) forces prevailing during the process. The total thickness selected here and / or the thickness of the starting material (semi-finished product) of preferably 8 mm or more, particularly preferably 15 mm or more, most particularly preferably 20 mm or more fulfills this task. The slope shown in Fig. 24 is suitable for allowing any condensing drops of the treatment medium to flow outwards overhead, so that they do not drip onto the polymer elements to be treated and leave damage and / or unsightly stains. In this embodiment, the cover 7 could also be referred to as a guide cover 97a, since its design fulfills this function. The visible, optional design with the groove 125 on the top sideof the cover 7 (wherein the recess thus created can alternatively have a shape other than a groove) can serve to accommodate or at least partially accommodate a heating device for heating the cover 7 on the top side of the cover 7. Further alternatively or additionally, the cover 7 is heated by a heating device which is not introduced into a recess. Optional elevations 127 (here blind holes, e.g. with an internal thread), recesses and / or the like can advantageously serve to connect the cover 7 of the chamber 1 to a housing cover (not shown) of the device 100, e.g. by screwing it. Alternatively, such blind holes are in the material of the cover without the need for upwardly projecting elevations 127. 84J GmbH & Co. KG Fig. 24a shows the cover 7 of Fig. 24 in a sectional view, perspective from above. Reference is made to the explanations for Fig. 24 in order to avoid repetition. Fig. 25 shows a part of a guide cover 97a,which is provided for attachment to a cover 7 of the chamber 1 of a device 100 according to the invention in a further embodiment, in a sectional perspective view from below. It preferably has a smaller diameter and / or a smaller material thickness than the cover 7, in particular than the cover 7 from Fig. 24. This is not apparent from Fig. 25. The size and material thickness are preferably selected such that the guide cover 97a is not damaged or deformed by the forces prevailing in the chamber during the process. The dimensions mentioned here and in particular for Fig. 24 can ensure this. Fig. 25a shows the guide cover 97a of Fig. 25 in a sectional perspective view from below. The visible configuration with the groove 125, elevations 127 (here with through openings 127a), recesses and / or the like can advantageously contribute to positioning and / or locking the guide cover 97a within the chamber 1.In such embodiments, the optional elevations 127 around the through-openings 127a can further have the function of an 84J GmbH & Co. KG spacer sleeve between the inside of the cover 7 and the guide cover 97a or can be provided for this purpose. In the example of Fig. 25 and Fig. 25a, as well as in any other embodiment, optional fastening elements such as three, four, five or more fastening screws or pins can be guided through through-openings 127a in order to be connected, for example, to the cover 7 of the chamber 1 (not shown in Fig. 24). The guide cover 97a optionally has - here: two - contact surfaces 129 to the cover 7 of the chamber 1 (not shown in Fig. 24), which are not axially spaced from the cover 7, but are in direct contact with it on its inside. This can serve, for example, to improve heat transfer from the inside of the cover 7 to the guide cover 97a.
