Description

[0001] Device and method for extracting one or more components, in particular cannabinoids such as tetrahydrocannabinol, from a mixture of substances

[0002] The invention relates to a device and a method for extracting one or more components, in particular cannabinoids such as tetrahydrocannabinol (THC) from a mixture of substances.

[0003] In known devices for extracting essential oils from plant material, plant material is introduced into a chamber or bladder of the device. Steam is then introduced into the bladder, preferably at a temperature of 180°C, which dissolves the essential oil from the plant material. Such steam distillation processes are typically operated in batch mode. The process is complete when the temperature of the plant material in the bladder has warmed to the temperature of the steam, since condensation of the steam on the plant material cannot then occur.

[0004] A particular disadvantage is that the process depends on the chamber load, since the plant material can be exposed to varying degrees of steam flow depending on the load level and density, and possibly also depending on the chamber dimensions. Plant material located further outwards is generally exposed to significantly better steam flow, while inner plant material may be covered by layers of plant material located further outwards. This can cause both the duration of the process and the amount of extracted essential oil to vary considerably. Likewise, it is difficult to adjust the average residence time of the plant material in the bladder or chamber.

[0005] The object of the present invention is therefore to provide a device and a method that enables a more reliable and uniform extraction and in which the residence time can be adjusted more precisely. These disadvantages are overcome by a device according to the invention and the method according to claims 1 and 23. Advantageous embodiments are the subject of the dependent claims.

[0006] The effect of cannabis extracts is primarily due to the active ingredient tetrahydrocannabinol (THC). The THC content can vary greatly from cannabis plant variety to cannabis plant variety. A THC content of more than 30% is possible in certain cannabis strains under optimal conditions. Currently, medical cannabis offers THC levels ranging from less than 1% to up to 22%, depending on the strain. The THC content of officially approved medical cannabis ranges from less than 0.05% to 10.2%.

[0007] To achieve optimal THC extract from the cannabis plant, it may be necessary to determine the THC qualitatively and / or quantitatively during the growth of the hemp plant in order to accurately determine the harvest time. Sensors, in particular at least one infrared sensor, can be used for this purpose. The sensors can be configured to record relevant biological data of the plant and, if necessary, store them in a database.

[0008] The device and the method according to the invention also allow both batch operation and continuous operation.

[0009] The device according to the invention for extracting one or more components, in particular THC and / or cannabinoids, from a substance mixture comprises a chamber, a plate accommodated in the chamber, at least one nozzle for feeding the substance mixture into the chamber and a static charging unit, wherein the static charging unit is designed to statically charge the substance mixture, wherein the plate has a charge opposite to the static charge of the substance mixture, so that the statically charged substance mixture, or at least components thereof, adheres or is adhesive to the plate.

[0010] The static charging unit can be configured to statically charge the substance mixture that has been fed into the chamber and / or is to be fed into it. The static charging unit can be configured to statically charge the substance mixture before, during, and / or after it is fed into the chamber. The statically charged substance mixture, or at least components thereof, can adhere to the plate. The plate can be configured to be brought to a predetermined charge. Provision can be made for bringing the charge of the plate to a nominal charge periodically or at least at predetermined time intervals. The plate can be configured to reverse its charge.

[0011] The mixture of substances can contain at least one or more of water, water vapor, and / or particles. The particles can be or contain hemp particles. The components to be extracted can be components of the particles. Water, water vapor, and / or particles can be components of the mixture of substances.

[0012] The adhesion of the mixture of substances and / or its components, particularly the adhesion of the particles, can ensure improved overflow, heat transfer, and / or mass transfer. The mixture of substances, its components, and / or particles can be distributed over the entire surface of the plate, resulting in a large surface area for overflow, heat transfer, and / or mass transfer. The static charge of the mixture of substances and / or the plate can be selected such that a predetermined layer thickness of the mixture of substances can adhere to the plate.

[0013] By dissolving the substance mixture and / or its components, in particular the particles, from the plate, the substance mixture can be removed from the chamber and / or an extraction area after extraction. The substance mixture can be dissolved from the plate, for example, by reversing the charge of the plate. Alternatively or additionally, the plate can be moved or shaken for dissolution. The time of dissolution can correspond to a predetermined residence time. The residence time can be selected such that a predetermined proportion of extract, e.g. per amount of substance mixture, is achieved. The substance mixture dissolved from the plate can fall downwards under the influence of gravity. The substance mixture dissolved from the plate can be discharged from the chamber through a flap and / or a discharge line.

[0014] The plate can be arranged opposite the at least one nozzle, so that the substance mixture supplied through the nozzle can be sprayed towards the plate and / or onto the plate. The device can have a heating unit that can be configured to heat the chamber and / or the plate. The heating unit can be configured to heat the chamber and / or the plate to a temperature of approximately 80°C to 120°C. It can be provided that the heat provided by the heating unit evaporates extracted extract or allows it to change from a liquid phase to a gas phase. The extract can comprise essential oil, in particular essential hemp oil.

[0015] The heating unit may comprise a hot air generator and a hot air blower. Provision may be made for the hot air generated by the hot air generator to be introduced into the chamber via a hot air supply by the hot air blower. The hot air may have a temperature of approximately 150°C to 200°C. Other suitable fluids or gases may also be used instead of hot air.

[0016] The heating unit may comprise a heating wire. The heating wire may be arranged on and / or in the chamber and / or the plate. The heating unit may be or comprise a jacket heater or the like.

[0017] The device may comprise a condensate collector arranged in the chamber. The condensate collector may be arranged on a top side of the chamber. The condensate collector may be configured to collect extract condensed in the chamber. The condensate collector may be fluidly connected to a condensate conveyor. Condensate collected in the condensate collector may be injected back into the chamber via the nozzles.

[0018] The device may comprise a tank fluidically connected to the chamber for receiving extract formed in the chamber.

[0019] The device may comprise a cooling unit, which may be fluidically arranged between the chamber and the tank. The cooling unit may be configured to liquefy the extract. The device may comprise a collecting container for receiving and / or forming the substance mixture, wherein the collecting container may be fluidically connected to the at least one nozzle.

[0020] The device may comprise a collection container heating unit that may be configured to heat the collection container and / or the substance mixture contained in the collection container. The collection container heating unit may be configured to heat the collection container to a temperature of 50°C to 120°C.

[0021] The device may comprise a grinder which may be connected to the collecting container so that material ground by the grinder, preferably hemp particles, may be introduced into the collecting container.

[0022] The device may comprise a grinder heating unit configured to heat the grinder. The grinder heating unit may be configured to heat the grinder to a temperature of 40°C to 300°C.

[0023] The grinding heating unit can be designed according to the principle of a drum mill or have a drum mill itself. Drum mills are used for the fine to ultra-fine comminution of various raw materials. They can have a substantially horizontally mounted, cylindrical or cylindrical-conical, rotating drum that defines a grinding chamber into which the material to be ground is introduced. Grinding media, which can be heated externally, can be arranged in the grinding chamber. By rotating the drum, the contents are circulated or tumbled, thereby comminuting the material to be ground. Balls made of steel or chilled cast iron, as well as steel rods, are primarily used as grinding media. If larger pieces of cannabis flower material (ground material) take over the function of the grinding media, this is referred to as autogenous grinding. Continuously operating drum mills usually have openings in the center of the end walls through which the flower material is fed into the grinding chamber or discharged.The ground pollen is discharged into a reservoir. The inner walls of the grinding chamber are subject to high stress and are therefore provided with a wear-resistant lining.

[0024] The grinder may be housed in a grinder chamber, which may have an air inlet and an air outlet, such that air can flow into the grinder chamber through the air inlet, through the grinder, the grinder chamber, and / or the material ground by the grinder, and out through the air outlet. The air may be or comprise hot air. The air may be or comprise air with a temperature between approximately 150°C and 300°C.

[0025] The device can have a sieve arranged between the collection container and the grinder. The sieve's grid spacing can be selected such that only particles with a certain maximum size can pass through the sieve. For example, the sieve can have a grid spacing of less than 500 pm. However, the sieve can also have a grid spacing of less than 200 pm and / or less than 20 pm. This can predetermine a maximum particle size in the mixture. The relatively small particle size can improve extraction.

[0026] The screen may be or include a vibrating screen. Alternatively or additionally, a vibrator may be connected to the screen, allowing the screen to be vibrated by the vibrator.

[0027] The mixture of substances can comprise the substance ground by the grinder, preferably hemp particles. The substance ground by the grinder, preferably hemp particles, can be a component of the mixture of substances. By crushing the particles of the mixture containing the components to be extracted, an improved extraction can result.

[0028] The collection container may have an inlet for supplying a fluid, wherein the fluid may contain the mixture of substances and / or an extractant that may form the mixture of substances with the ground particles in the collection container. The extractant may be or may contain water and / or steam. The extractant may be a component of the mixture of substances.

[0029] The plate can be movably received in the chamber. The plate can be attached with a suspension. The suspension can have a spring element or the like. The suspension can be configured to allow movement of the plate. The device can have a vibrating device that can be configured to vibrate the plate. The device can have a control unit for controlling a temperature of the chamber and / or the plate, for controlling the supply of the substance mixture and / or for controlling the static charge of the substance mixture and / or the plate. The control unit can be configured to control the extraction process. The control unit can control or regulate one, several or all controllable parts of the device, such as conveyor units, valves, heating elements, flaps, mills or the like.

[0030] The device may include at least one temperature sensor arranged on or in the chamber. At least one, several, or all of the temperature sensors may be connected to the control unit.

[0031] The device may comprise at least one optical sensor arranged on or in the chamber. The optical sensor may be or comprise a camera. The optical sensor may be connected to the control unit.

[0032] According to a further aspect, the invention relates to a method for extracting one or more components, in particular THC and / or cannabinoids, from a substance mixture, comprising the following steps: feeding a substance mixture into a chamber of an extraction device; statically charging the substance mixture with a static charge by means of a static charging unit; adhering the statically charged substance mixture or at least components thereof to a plate accommodated in the chamber and charged with a charge opposite to the static charge; detaching the substance mixture adhering to the plate or its components from the plate after a predetermined adhesion time has elapsed. The adhesion time can correspond to a residence time. The adhesion time can be predetermined.

[0033] The order of several steps can be interchanged. For example, static charging can be performed before adding the mixture.

[0034] Detaching from the plate may involve shaking the plate. Alternatively or additionally, detaching from the plate may involve reversing the charge of the plate. The chamber and / or the plate may be heated to a temperature of approximately 80°C to 210°C.

[0035] An extract formed in the chamber can be removed from the chamber. The resulting extract can be cooled and / or liquefied.

[0036] The cooled and / or liquefied extract can be separated. For this purpose, a vacuum extraction process can be planned or carried out, for example.

[0037] The mixture of substances can be formed in a collection container and / or fed into the chamber from a collection container. The mixture of substances can comprise at least one of particles, water, and / or water vapor. The particles can be or include hemp particles.

[0038] The particles can be ground with a grinder and fed into the collection container. The particles can be ground by the grinder such that they have an average size of less than 500 pm, preferably less than 200 pm, and particularly preferably less than 20 pm.

[0039] The particles ground by the grinder, in particular hemp particles, can be passed through by air before being fed to the collection container. Hot air can be passed through the particles. The particles can be passed through by air with a temperature between approximately 150°C and 300°C. Passing through the particles can involve flowing around or over the hemp particles.

[0040] The particles ground by the grinder can be sieved through a sieve before being fed to the collection container. The particles can be sieved through a vibrating sieve. Sieving ensures that only particles of a maximum size can be used in the process.

[0041] The collection container can be heated to a temperature of approximately 50 °C to 120 °C. The process can be carried out using a device as described above.

[0042] The invention is further explained with reference to the following figures.

[0043] Fig. 1 shows a first embodiment of a device according to the invention;

[0044] Fig. 2 shows a second embodiment of a device according to the invention;

[0045] Fig. 3 shows a third embodiment of a device according to the invention.

[0046] Figure 1 shows a first embodiment of a device 1 according to the invention. The device 1 comprises a chamber 8, a plate 7, at least one nozzle 5, and a static charging unit 6. The plate 7 is arranged in the chamber 8. A substance mixture 4 can be introduced into the chamber 8 via a supply line 10. The supply line 10 can be fluidically connected to the at least one nozzle 5, so that the substance mixture 4 can be sprayed into the chamber 8.

[0047] The chamber 8 and / or the plate 7 can be heated. The device 1 can for this purpose have a heating unit. For example, the heating unit can have a heating wire 19. The heating wire 19 can comprise a heating coil and / or heating spiral. The heating wire 19 can, for example, be guided through the interior of the plate 7. Alternatively or additionally, the heating wire 19 can be arranged in the chamber 8 or around it. Alternatively or additionally, the heating unit can heat the chamber 8 and / or the plate 7 using hot air. For this purpose, the device 1 can have a hot air supply 13, by means of which hot air can be introduced into or passed through the chamber 8 and / or the plate 7. The hot air supply 13 can be suitably guided. In an embodiment not shown, the hot air supply 13 can, for example, be guided in a serpentine manner through the plate 7.However, it can also be provided that hot air is introduced into the chamber 8 through the hot air supply 13. For example, the heating unit can have a hot air generator 40 and / or a hot air blower 39, see Figure 3. Instead of hot air, another suitable fluid can also be used, by means of which the heating unit can heat the chamber 8 and / or the plate 7. Alternatively or additionally, the heating unit can be or have a jacket heater, which can, for example, heat an inner wall of the chamber 8.

[0048] The heating unit may be configured to heat the plate 7 and / or the chamber 8 to a temperature of approximately 80°C to 120°C. The hot air may have a temperature of approximately 80°C to 120°C.

[0049] The plate 7 can be arranged in the chamber such that it can be positioned substantially opposite the nozzles 5 and / or in the spray direction. This can result in a good distribution of the substance mixture 4 to be sprayed on the plate 7.

[0050] The substance mixture 4 may contain water, water vapor, and / or particles. The particles may, in particular, be or contain hemp particles. The particles may be or contain ground or otherwise comminuted particles. The particles may contain the components to be extracted.

[0051] The particles may in particular contain THC and / or cannabinoids, which can be extracted by means of the device 1 and / or the corresponding method. The particles may, for example, contain A 9-THC. Cannabinoids can include, for example, cannabigerol (CBG), cannabichrome (CBC), cannabidiol (CBD), cannabinodiol (CBND), tetrahydrocannabinol (THC), cannabinol (CBN), cannabitriol (CBT), cannabielsoin (CBE), isocannabinoids, cannabicyclol (CBL), cannabicitran (CBT), and / or cannabichromanone (CBCN).

[0052] Extraction can be carried out by evaporation and subsequent condensation. In chamber 8, the substance mixture 4 can be heated or maintained at temperature. The water and / or steam can serve as solvents for extracting components contained in the particles. The steam can contain at least one solvent. This makes it possible to extract THC or CBD from the flowers. The most commonly used solvents are propane, CO2, isopropyl alcohol, dimethyl ether, ethanol, and butane. At the end of the process, these contain the plant's constituents, such as THC or CBD. Depending on the plant species, the concentration of THC or CBD in the solvent can be between 70% and 99% by volume. For example, the steam can condense on the particles, e.g., if the particles have a lower temperature than the water vapor or are cooler.The condensed water can wet the particles, whereby substances contained in the particles, e.g. essential oils, in particular essential hemp oils, can diffuse out of the particles. This can result in an oil-water mixture. It can be provided that the condensation of the water vapor on the particles takes place before they are fed into the chamber 8. The condensation can take place, for example, in a collecting container 34, see, for example, Figure 2. The substance mixture 4 can comprise or be the oil-water mixture. The oil-water mixture can evaporate when heated. It can be provided that the oil-water mixture is introduced into the chamber through the nozzles 5. This heating can take place in the chamber 8, e.g. preferably on the plate 7. The substance mixture 4, in particular the oil-water mixture, can be evaporated in the chamber 8, preferably on the plate 7. The particles, or at least residual components or non-evaporated components of the particles, can remain behind.The evaporated oil-water mixture and / or the evaporated substance mixture 4 can rise upwards under free convection and be discharged via a withdrawal line 2 as extract 35 from the chamber 8 and / or the device 1.

[0053] Alternatively or additionally, it can also be provided that the water of the substance mixture 4 evaporates in the chamber 8, e.g., particularly at the plate 7, thereby dissolving the substances or components from the particles. The extract thus formed can be discharged from the chamber 8 or the device 1 via the extraction line 2.

[0054] Alternatively, the substance mixture 4 fed to the chamber can comprise the particles but no solvent, in particular no water and / or water vapor. After the substance mixture 4 or the particles have been fed into the chamber 8, water vapor and / or water can then be fed to the chamber as a solvent. The water and / or water vapor can wet the particles, dissolve the substances from the particles and then be discharged as extract 35 from the chamber 8 or the device 1 via the extraction line 2. It can be provided that water vapor can first condense on the particles as described above. It can also be provided to use a solvent other than water and / or water vapor.

[0055] The extract 35 can comprise the vaporized oil-water mixture and / or the vaporized substance mixture 4. It can be provided that the extract 35 and / or the vaporized substance mixture 4 does not include the residual components of the particles or their non-vaporized components. The residual components of the particles or their non-vaporized components can be discharged from the chamber 8 or the device 1 via a flap 22 and / or an outlet line 3.

[0056] Since the partial vapor pressures of the oil-water mixture can add up, evaporation can be achieved at temperatures just below 100°C. Due to the low evaporation temperature, the aroma of the extract 35 or its components can be enhanced and / or preserved.

[0057] The internal pressure of chamber 8 can be substantially equal to atmospheric pressure or approximately 1 bar. It can also be provided that a vacuum or a pressure of up to 100 bar is present in the chamber. The temperature inside chamber 8 and / or the temperature of the plate can be between approximately 80°C and 120°C.

[0058] The static charging unit 6 is configured to statically charge the substance mixture 4. The static charging can occur before the substance mixture 4 is fed into the chamber 8, during feeding into the chamber 8, or after feeding into the chamber 8. The static charging unit 6 can be arranged accordingly for this purpose. For example, the static charging unit 6 can be arranged in the chamber 8. The static charging unit 6 can charge the substance mixture 4 positively or negatively. The static charge can be an electrostatic charge. For example, the static charging unit 6 can be configured to generate an electric field through which the substance mixture 4 can be passed.Alternatively or additionally, the static charging unit 6 can be arranged fluidically downstream of the nozzle 5, so that the substance mixture 4 can be sprayed through the static charging unit 6 and / or an electric field generated by the static charging unit 6. When the substance mixture 4 is passed through and / or sprayed through the electric field, the substance mixture 4, in particular particles contained in the substance mixture 4, can be statically charged. The substance mixture 4, in particular particles contained in the substance mixture 4, can be statically charged by the static charging unit 6 by means of a field charge.

[0059] The plate 7 has a charge that is opposite to the static charge of the substance mixture 4. If, for example, the substance mixture 4, e.g. particles thereof, is negatively charged, e.g. due to the static charging unit 6, the plate 7 can be positively charged. If, for example, the substance mixture 4 is positively charged, the plate 7 can be negatively charged. This allows the statically charged substance mixture 4, e.g. particles of the substance mixture 4, to adhere to the plate 7, e.g. due to the Coulomb force. The static charge of the substance mixture 4 and the charge of the plate 7 can be suitably selected for this purpose. For example, the static charging unit 6 and / or the plate 7 can be controlled or regulated accordingly. For example, it can be provided to suitably select or control the composition of the substance mixture 4, in particular the proportions or weight proportions of its components, the particle size, the strength of the electric field and / or the charge of the plate 7.

[0060] The adhesion of the substance mixture and / or its components, in particular the adhesion of the particles, can ensure improved overflow, heat transfer and / or mass transfer. In particular, this can ensure that the particles containing the components to be extracted do not collect at the bottom of the chamber 8, but can be evenly distributed on the plate 7. This can result in improved extraction. The static charge of the substance mixture 4 and / or the plate 7 can be selected or controlled such that a predetermined layer thickness of substance mixture 4 can adhere to the plate 7. It can be provided that the layer thickness is selected, for example, as a function of a predetermined residence time, the adhesion time and / or the heat and mass transfer through the layer or the like.

[0061] It can be provided that the substance mixture 4 adhering to the plate 7, and / or particles of the substance mixture 4, are released from the plate 7. The release can be carried out, for example, by shaking or moving the plate 7. Alternatively or additionally, the charge of the plate can be reversed so that it corresponds to the charge of the substance mixture 4, whereby the substance mixture 4 can be released from the plate 7. If the device is operated in batch mode, it can be provided that the release takes place at a predetermined time after the substance mixture 4 has been sprayed in. If the device is operated continuously, it can be provided that the release takes place periodically. The time and / or the period length or the adhesion time can be selected such that it corresponds to a predetermined residence time. The residence time and / or the adhesion time can be selected such that a predetermined proportion of extract, e.g. per amount of substance mixture, is achieved.The mixture of substances released from the plate can fall downward under the influence of gravity. The mixture of substances released from the plate can be discharged from the chamber through a flap and / or an outlet line.

[0062] The residence time and / or the adhesion time can depend on or be selected based on the particle size, the temperature of the plate 7 and / or the chamber 8, the amount of solvent or the amounts or weight proportions of the components of the substance mixture and / or the components to be extracted.

[0063] The plate 7 can be movably mounted with a suspension 30, so that the plate 7 can be shaken to loosen adhering substance mixture 4 and / or particles. For example, the plate 7 can be attached via the suspension 30, e.g., to an inner side of the chamber 8. However, it can also be provided that the suspension and / or the attachment of the plate is not arranged in the chamber 8, in particular, cannot come into contact with the substance mixture 4 and / or is not fluidically connected to the chamber 8.

[0064] The device 1 can have a flap 22, by means of which the substance mixture 4 fed into the chamber 8 and / or the substance mixture 4 dissolved from the plate 7, in particular particles thereof, can be discharged from the device 1 and / or the chamber 8. Alternatively or additionally, the device 1 can have a discharge line 3 through which the substance mixture 4 can be discharged from the chamber 8. A valve 12 can be arranged in the discharge line 3, by means of which the discharge line 3 can be opened and / or closed. The valve 12 can be connected to a control unit so that the valve 12 can be controlled, in particular opened or closed.

[0065] The device 1 can have a condensate collector 31. The condensate collector 31 can be configured to collect condensate formed in the chamber 8. The condensate collector 31 can be arranged on an upper side of the chamber 8. It can be provided that condensate formed on the upper side of the chamber 8 is captured or collected by the condensate collector 31. The condensate collector 31 can be fluidically connected to a condensate conveyor 11. The condensate conveyor 11 can be or have a pump. The condensate conveyor 11 can be configured to transport away condensate collected in the condensate collector 31. For example, the condensate collected by the condensate collector 31 can be discharged from the device 1. Alternatively or additionally, the collected condensate can be added to the substance mixture 4 and / or reintroduced into the chamber 8 of the device 1.

[0066] The condensate can be filled into capsules within the device. The capsules can be inserted into a tube-like magazine in a vaporizer. The capsules can be separately heated so that the condensate (active ingredient) can be administered in portions. Upon activation of the heating unit and inhalation, fresh air can be mixed with the aerosol. A further embodiment of the invention provides for the described device or parts thereof to be incorporated into a vaporizer or inhaler. Oral consumption or vaporization of the generated condensate in a vaporizer prevents exposure to the respiratory tract by avoiding carcinogenic substances produced during combustion. Combustion does not occur in the new process.

[0067] The device 1 can have at least one temperature sensor 17 that can measure a temperature of the chamber 8 and / or the plate 7. At least one temperature sensor 17 can be arranged in or on the chamber 8 and / or the plate 7. It can be provided that temperature sensors 17 are arranged vertically in the height direction of the chamber 8. The temperature sensor 17 can be connected to the control unit so that the control unit can record temperature values ​​measured by the temperature sensor 17.

[0068] Figure 2 shows a further embodiment of a device according to the invention. The embodiment shown in Figure 2 may have some, several, or all of the features shown in Figure 1 and / or described above.

[0069] The device 1 can have a collecting container 34. The collecting container 34 can be fluidically connected to the nozzle 5 via the feed line 10. The mixture of substances 4 can be or will be received in the collecting container 34. The collecting container 34 can have an outlet 14 through which the mixture of substances 4 can enter the feed line 10 from the collecting container 34. A conveying unit 28 can convey the mixture of substances 4 from the collecting container 34 to the at least one nozzle 5. The conveying unit 28 can be or have a pump, for example. The feed line 10 can have a Venturi nozzle 29. The collecting container 34 can have an inlet 24 through which the mixture of substances 4 and / or components of the mixture of substances 4, in particular water and / or water vapor, can be introduced into the collecting container 34.

[0070] The device 1 can comprise a collection container heating unit (not shown in the figures). The collection container heating unit can be configured to heat the collection container to a temperature of approximately 50°C to 120°C. The collection container heating unit can be or comprise, for example, a hot wire and / or a jacket heater.

[0071] The device 1 can have a grinder 15. The grinder 15 can be arranged in a grinder chamber 16. Material to be ground, held in a container 46, can be fed to the grinder 15 and ground into particles by the latter. The ground particles can have an average grain size and / or average particle diameter of less than 500 μm. The ground particles can have an average grain size and / or average particle diameter of less than 200 μm. The ground particles can have an average grain size and / or average particle diameter of less than 20 μm. The material 27 to be ground can be or comprise hemp, in particular hemp flowers or hemp leaves. The ground particles can be or comprise hemp particles.

[0072] The device 1 can have a grinder heating unit. The grinder heating unit can heat the grinder 15 to a temperature between approximately 40°C and 300°C. The grinder heating unit can be accommodated in the grinder and / or thermally connected to it. The grinder can be heated, for example, by a hot wire in or on the grinder and / or by heat conduction. Alternatively or additionally, the grinder can be heated by convection using hot air. By heating the grinder, the ground material can be or will be preheated, for example.
