TOOL FOR HOELESSING FOOD

Description

[0001] This invention relates to a device, a tool, for hollowing out foodstuffs, preferably sausages, along their entire elongated length, in order to subsequently fill the foodstuffs or sausages with other foodstuffs as desired.

[0002] From DE 82 30 391 U1, a core drill for pome fruit, such as apples, is known. This drill comprises a tubular shaft, the front circumferential rim of which is designed as a cutting edge. Furthermore, there is a plunger inside the shaft, which can be moved from a retracted position to a forward position. At least one handle protruding from the shaft and acting upon the plunger is provided for this purpose. The shaft is axially slotted, with the slots serving as a guide for the handle. At its rear end, the core drill includes a collar that absorbs the axial pressure necessary for extracting a core.

[0003] GB 2 488 597 A describes a device for hollowing out food.

[0004] The device comprises a support beam with a first blade attached to its end. The support beam can thus be inserted into the food to be hollowed out. A second blade is guided within the support beam and can be pushed towards the first blade by a pressure motion.

[0005] The object of the invention is to provide an improved device for hollowing out food.

[0006] This is achieved by a tool according to claim 1 and by a method according to claim 15.

[0007] The invention consists of a support beam, ( Fig 1 , Fig. 6 ) a towing device, ( Fig.2 ) preferably a thin stainless steel cable and a knife or blade, ( Fig.2 Nos. 11, 12, 13 Fig. 7 and 8No. 11, 13) which is preferably circular, and a conical tip on the pulling tool ( Fig. 2 , 7 , 8 (No. 9) In a further embodiment, the knife can have any desired shape, angular, oval, triangular, etc. The tip can also deviate from a conical shape. The support shaft is elongated and accommodates the pulling device to which the knife is attached. During its passage through the food, the knife is guided by the pulling device, either within or along the support shaft, to achieve a cut in the food that corresponds to the shape of the support shaft and whose shape is adapted to the desired hollowing result. At the end of the pulling device, opposite the knife, is the tip, which facilitates piercing the food with the support shaft and the pulling device.

[0008] There is a wide variety of food hollowing tools available on the market, including corers with a handle and a hollow, elongated cutting tool, or with claws or teeth.

[0009] However, this invention is designed to hollow out the sausage or food in a targeted manner, centrally, with an exact distance to the support beam, in a round or circular shape, which in turn corresponds to the shape of the inserted or used knife; preferably, the hollowing out is carried out in a circular shape along the length of the food.

[0010] This invention aims to offer more variety in traditional, monotonous cuisine. In particular, it allows sausages to be filled with desired foods or ingredients, thus providing a more diverse culinary experience.

[0011] These tasks are solved by making the support beam hollow inside in order to accommodate the pulling tool / pulling device.

[0012] In one embodiment, the support pole is elongated and straight and somewhat longer than conventional sausages, but its length can also vary as desired.

[0013] In another embodiment, the support beam is already slightly bent, so that it roughly corresponds to the bend of some types of bratwurst.

[0014] In another embodiment, the support beam is made of a stable yet flexible material, such as aluminum, allowing the user to create the required shape of the support beam themselves, and ensuring that shape is retained. After use, the support beam can be bent back into its original shape.

[0015] The support beam is preferably round, like a thin tube, which is provided with a slot that preferably extends along its entire length. The tube is thus opened by an elongated slot. The rectangular part of the knife later runs in this slot, and the cylindrical center of the knife runs in the further cavity of the support beam as it is pulled through the beam by the pulling device.

[0016] In another embodiment, the support beam can also be square, triangular or oval, but elongated.

[0017] It is also conceivable that the support beam is merely an elongated tube or an angular elongated body - which need not be hollow but can also consist of solid material - without being provided with a slot.

[0018] In this case, the knife would sit on a hollow shaft with a larger diameter, which acts as a pulling device, and whose shape of the cavity of the embodiment (round, oval, square, triangular, etc.) corresponds to the shape of the support shaft and is pushed onto the support shaft.

[0019] In this embodiment, the knife, which is preferably circular, is attached with its rectangular blade directly to the larger diameter tube, which acts as a pulling device ( Fig. 4 . No. 13) For better stability, it can also be attached to the pulling device with 2 rectangular knives.

[0020] In this embodiment, the entire, pushed-on, hollow shaft itself can also represent the knife ( Fig. 5 No. 19) by attaching the spar at its front, preferably circular area ( Fig.5 .No. 21) is sharpened.

[0021] In this embodiment, the support beam is first ( Fig 5 No. 1) pushed through the food and the hollow stem, ( Fig. 5 . No. 19) which in its entirety functions as a knife, which is sharpened in its front area ( Fig. 5 No. 21) is pushed onto the handle from behind and pressed through the food. This again achieves a precise cut along the handle. The handle that is pushed on has at least one ring in its hollow center, ( Fig. 5 No. 20) which, in terms of its inner diameter, fits exactly onto the support beam ( Fig. 5 No. 1) fits and again with a rectangular knife ( Fig. 5 No. 13), which is responsible for the distance and its stable position between the support beam and the pushed-on beam, which acts as a knife.

[0022] The aim of the embodiments is to push or, if necessary, pull the knife precisely along the support shaft, without deviations, through the food.

[0023] In this embodiment, the support beam with the elongated slot can be provided with barbs on the outside, at least on one side, preferably at several points, ( Fig. 1 No. 4) which therefore thicken in the opposite direction to the insertion direction or drilling direction.

[0024] After the knife has been pulled through the food using the pulling device, the knife and pulling device can be removed from the other side of the food. The support bar, with its barbs, is then pulled out of the food in the opposite direction of the pull. This causes the cut-out contents of the food to adhere more easily to the support bar due to the barbs, allowing them to be removed from the food and creating the desired hollowing effect.

[0025] In the embodiment in which the support beam is without a slot, hollow, or made of solid material, and in which a beam with a larger diameter is pushed onto the actual support beam as a pulling device with the knife attached to the end, ( Fig.4 Nos. 1, 18) can have barbs made of springy material ( Fig.4 No. 4) on the actual support beam, which, when the hollow beam is pushed on with the knife, are spring-loaded and either plunge into the actual support beam or are only pressed down, provide this relief in removing the cut-out material by rising up after the hollow beam has been pulled off and acting as hooks.

[0026] In this embodiment, the support beam was connected to its tip ( Fig. 4 No. 16) together with the attached pulling device, the knife is pushed through the food by pulling on the attached pulling device to which it is attached, along the support bar through the food and pulled off the support bar at the other end. The end plate ( Fig. 4 No. 22), which has a larger surface area than the cutout made in the food by the knife, holds the support beam securely in the food when the pulling device is pulled, preventing it from being pulled through. The attachment of the support plate can be analogous in one embodiment ( Fig. 1 Nos. 5, 6, 7, 8) are carried out, except that the nose of the cover plate ( Fig. 1 No. 6) only fits into a recess (No. 7) in the support beam and is locked in place by turning.

[0027] Preferably, however, the support beam is provided with a slot along its entire length into which the pulling tool, preferably the stainless steel cable, is inserted. Fig. 1 )

[0028] The slot in the support beam can be made so thin that it merely guides the square blade along its length, and the pulling device is simply inserted into the hollow of the support beam, rather than being inserted into it. In this configuration, the square blade runs within the slot, and a body within the hollow of the support beam, adapted to the specific shape of the support beam (round, square, triangular, oval), rests at the center of the blade. This means that the slot can be made narrower.

[0029] In another embodiment, this slot is slightly enlarged in width at at least one small point so that a thickening of the drawing tool can be inserted there. Preferably, there are two or three such enlargements along the longitudinal course of the slot. Fig. 1 No. 3, Fig. 2 No. 10)

[0030] Once inserted, the thickening(s) of the pulling device cannot jump out of the slot of the support beam during the pulling process, thus stabilizing the entire pulling device.

[0031] This measure is necessary to ensure that during the pulling process on the rope or, in another embodiment, on the inserted pulling tool (a wire or a thin rod), the pulling tool is held in the handle and does not jump out, in order to prevent injuries or unsuccessful results.

[0032] However, embodiments are also conceivable in which this guiding measure is dispensed with and the slot in the support beam is designed continuously without enlarged openings and the pulling tool is also designed without thickenings.

[0033] In another embodiment, the support beam has a joint at one point, preferably in the middle, so that it can be folded up and stored more easily.

[0034] If the pulling device consists of a stainless steel cable, it is designed without a joint. If the pulling device is made of rigid material, it may also be equipped with a joint.

[0035] In the embodiment in which a hollow spar with the knife at the end is pushed onto the actual support spar, ( Fig. 4 ) Both the actual support beam and the beam with the knife, which is pushed onto the actual support beam, can be provided with a joint so that the entire device can be folded up.

[0036] At one end of the pulling tool, preferably the stainless steel cable, wire or thin rod, there is a conical tip, ( Fig. 2 , 7 , 8No. 9) which makes it easier to pierce the food with the support bar.

[0037] The drawing tool has a thickening in the form of a short, small cylinder at at least one point along its elongated path, preferably at 2-3 points ( Fig. 2 No. 10) or a ball which is slightly smaller in diameter than the inner diameter of the support beam, in order to be guided in the slotted tube of the support beam when tightening.

[0038] These thickenings also fit into the enlarged slots of the support beam when inserting the pulling tool. Fig. 1 No. 3)

[0039] The thickenings of the pulling device are adapted to the cavity shape of the support beam (round, square, oval, triangular, etc.). Preferably, however, they are round, cylindrical, and have a diameter slightly smaller than the inner diameter of the support beam in order to ensure an exact, stable pulling path during the pulling of the pulling device.

[0040] At one end of the pulling tool, preferably the stainless steel cable, a preferably circular blade is attached, which, however, as described, can also have any other shape suitable for hollowing out the food. Fig. 2 Nos. 11, 12, 13 Fig. 7 and 8 Nos. 11, 13)

[0041] In another embodiment, this blade is replaceable so that it can be renewed when it loses its sharpness or if a different diameter of the cavity created in the food is desired. The blade can therefore preferably be smaller or larger in diameter, or in other embodiments simply have a different dimension.

[0042] Interchangeability is achieved in one embodiment by having the pulling device have an eyelet and the knife a hook. However, it can also be solved by providing an internal thread in the cylindrical body of the knife ( Fig. 2 No. 12) and has an external thread on the pulling device, which is screwed in there.

[0043] At the other end of the pulling tool, the pulling device, preferably the stainless steel cable, a conical tip is attached to enable the piercing of the food. This conical tip may have a nose that secures the tip in the slot of the carrier handle during piercing. Fig. 2 No. 14) Furthermore, the tip may preferably have a cylindrical part ( Fig. 2 No. 15) which is slightly smaller in diameter than the diameter of the support bar, so that the tip gains a secure hold when it is placed on the support bar. The tip is thus held firmly in place by the cylindrical body within the support bar's cavity and by the nose in the slot of the support bar, preventing it from twisting while piercing the food.

[0044] This tip can be conical or any other shape that facilitates piercing; it can even be flat, similar to an ancient arrowhead. The tip is firmly attached to the pulling mechanism.

[0045] In embodiments where the shape of the actual support beam deviates from the round, tubular shape, the cylindrical stabilizing body of the tip can be adapted to the respective shape of the support beam's hollow design, but its dimensions are kept minimally smaller than the hollow dimensional space of the support beam (angular, oval, triangular, etc.).

[0046] It is also conceivable to use designs in which the pointed end can be omitted. In this case, the food is pierced with the support bar, and the pulling device is inserted by pushing it in until it protrudes at the other end of the food. A simple eyelet system can be used to attach a pulling aid, such as a ring, to facilitate the transfer of the pulling force to the pulling device.

[0047] The knife is preferably circular in shape - however, depending on the desired hollowing result, it can deviate from the circular shape (i.e., be square, oval, triangular).

[0048] The knife is cast in one piece and yet has three important components within this workpiece: In the embodiment with the tubular, round, hollow support beam, a cylindrical body which is made slightly smaller in diameter than the inner diameter of the support beam into which it is intended to be inserted, and which is long enough to prevent the knife from tilting in the hollow of the support beam during the pulling process. Fig. 3 No. 12) A square knife ( Fig. 3 , 7 , 8 No. 13) which connects to the cylindrical body and, after being inserted or pushed into the support beam, into the slot of the support beam ( Fig. 1 , 6 , 7 , 8 No. 2) runs, as well as the circular blade ( Fig. 3 , 7 , 8 No. 11) which connects to the square blade. These components create a stable, unified blade.

[0049] In other embodiments, the cylindrical body of the knife is shaped differently and adapts to the respective cavity shape of the corresponding embodiment, the support beam.

[0050] The blade is therefore preferably circular. The connection between the pulling device and the blade can be made by means of a simple hook (eyelet + hook) or, as described, with a threaded connection.

[0051] The pulling device, preferably a stainless steel cable, is inserted into the support beam. The tip, which may be permanently attached to the pulling device, is inserted into the support beam and secured by the nose and cylindrical guide in the beam. The support beam, with the pulling device now inserted through the slot or into the cavity, is pushed through the food with the tip leading and emerges at the other end. By gently pulling on the tip, the blade, which is attached to the pulling device, preferably the stainless steel cable (hooked or screwed in), and located at the other end, is drawn with its cylindrical body into the other end of the support beam so that the square blade of the blade ( Fig. 3 , 7 , 8 No. 13) in the slot of the support beam ( Fig. 1 , 6 , 7 , 8 No. 2) runs and the cylindrical body ( Fig. 3 No. 12) in the support beam. This fixation ensures that the knife runs precisely along the support beam through the food during the pulling process, even in the embodiment where the support beam is flexible. In this case, the pulling device is also flexible, similar to a wire or steel cable.

[0052] The blades of the knife in all embodiments, including the square stabilizing blade, are sharpened at least in the direction of pull through the food.

[0053] If the support beam is not round, i.e., like a tube, but rectangular, the cylindrical body of the knife of the aforementioned design can also be rectangular, so that it fits into the cavity of the support beam with little clearance and can slide in the cavity during the pulling process on the pulling device, thus stabilizing the knife in the process.

[0054] The blade is attached to one end of the pulling device. In another embodiment, this attachment can also be detached (hook, eyelet, internal thread on the cylindrical body of the blade and external thread on the pulling device, etc.) so that the blade is replaceable if it becomes dull, or if a smaller or larger dimension or a different shape is required.

[0055] In the final step, the pulling device, preferably the stainless steel cable, is inserted into the slot of the support beam, and the conical tip is fixed as described. The food is then pierced with this connection. By pulling on the now protruding conical tip, the pulling force draws the pulling tool, preferably the stainless steel cable with the knife at the other end, which is guided in the channel of the support beam, through the food along the length of the support beam without any deviation. By pulling the cable completely through, the knife can be pulled out of the support beam via the slot and opening.

[0056] The support beam with its barbs ( Fig. 1 No. 1,4) is now pulled out of the food in the opposite direction. This removes the cut-out contents of the food that are attached to the support bar, resulting in a shape that corresponds to the blade used.

[0057] Now the food item can be filled with the desired contents. The extracted contents can be further processed, possibly used to seal the two openings created in the food item after it has been filled as intended.

[0058] The entire device can be made from any material that meets the requirements and produces the desired result. A design made entirely of plastic, or partially of plastic combined with steel, is also conceivable and feasible. Aluminum is suitable for flexible designs.

[0059] A finishing plate is attached to the end of the support beam ( Fig.1 No. 5) is attached and held in place, for example, by the fact that the support beam is round, a cylindrical part of the end plate ( Fig. 1 No. 8) with an inner diameter slightly larger than the outer diameter of the support beam, onto which it is placed and secured by a slight twist with a nose ( Fig. 1 .No.6) in the cylindrical body, ( Fig. 1 No. 8) which is inserted precisely at the slot of the support beam when attaching, engages in a groove of the support beam by a slight turn, ( Fig. 1 No. 7) so that the end plate cannot fall backwards.

[0060] This measure ensures that the support beam is held in the food during the pulling action and the work step performed by the knife, i.e., it is not pulled through, since the diameter of the end plate is larger than the diameter of the knife.

[0061] The support beam can be made of any suitable material. Stainless steel, aluminum, plastic, or even ceramic are all possibilities. Versions without thickening or enlarging the continuous slot, in the form of cutouts in the support beam, are also available and possible.

[0062] The thickened sections in the slot of the support beam become necessary when the pulling device consists of a thin stainless steel cable whose diameter is smaller than the slot in the support beam. In this case, the stainless steel cable also has corresponding thickened sections, which are slightly smaller than the recesses in the support beam. When the cable is correctly inserted into the recesses of the support beam, especially in designs with a curved support beam, it cannot jump out of the guide, or more precisely, out of the slot, during the pulling process. Instead, it remains held in place within the hollow of the support beam by the thickened sections.

[0063] In embodiments of the support beam with a continuous, uniformly wide slot without thickenings or, more precisely, recesses, the pulling device with the knife can, as already described, also be inserted into the cavity of the support beam. It is then not inserted via the slot of the support beam. The pulling device is then designed not as a rope but as a rod ( Fig. 7 No. 22). The square knife then runs in the slot of the support beam after being inserted, ( Fig. 6 , 7 , 8No. 2) The pulling device with the cylindrical part of the blade runs in the cavity of the support beam. The blade, which corresponds in dimensions to the desired hollowing result, whether circular or otherwise shaped, then, after the food has been pierced with the tip leading the pulling device, runs along the outside of the support beam through the respective food, maintaining a precise distance, by pulling on the tip, guided by the support beam and its connection to the square blade, the pulling device and / or the cylindrical body.

[0064] The pulling device can also be designed without thickenings and consist of an elongated rod. Fig. 7 No. 22) This rod can be made of any suitable material. Stainless steel, aluminum, plastic, or ceramic are all possibilities. In another embodiment, this rod is threaded at both its front and rear ends to accommodate a point at the front and a blade at the rear. For this purpose, the rod is provided with external threads, while the blade and point are fitted with matching internal threads, or vice versa. Both the point and the blade are then replaceable. The blade's thread is located centrally within the cylindrical body of the blade. The point's thread is located centrally opposite the actual point, i.e., in the rear, non-pointed section. This design facilitates the replacement of dull blades or points. If the pulling device is in the form of a stainless steel cable, it can be inserted into the support beam via the slot.In embodiments where the pulling device is a rod, it can be inserted into the cavity of the support beam. Since the support beam is open at both ends like a tube, and the slot is continuous, the pulling device with the knife can be inserted from either side before piercing the food. If the knife is inserted into the slot first, the tip can already be attached to the pulling device. If the pulling device is inserted first, the tip will only be opened once the pulling device protrudes from the front of the support beam. If the rod is thinner in diameter than the slot in the support beam, it can also be inserted through the slot.

[0065] The square knife ( Fig. 2 , 7 , 8, No. 13) can have any shape other than a square one, which, in terms of its width, can run in the slot of the support beam and sufficiently stabilizes the knife running on the outside of the support beam.

[0066] In another embodiment, the pulling device, knife and tip are manufactured in a single mold as a unit using injection molding or welding.

[0067] The knife does not have to be cast from a single piece; it can also be made of individual parts joined together. This can be done using welding techniques.

[0068] The function of the cylindrical body of the knife—namely, to guide the knife stably within the hollow of the support bar—can, in another embodiment, also be performed by the pulling device itself, provided it is designed as a rod with an outer diameter only slightly smaller than the inner diameter of the support bar. In this case, the square knife is connected to the pulling device, which runs within the hollow of the support bar, either by casting or welding. As described, the square knife is guided through the slot in the support bar during the pull-through of the food, holding the knife in place. This knife creates the desired hollowing result, whether circular or of another shape, which runs along the outside of the support bar, maintaining a precise distance from the food during the pull-through process.

[0069] Suitable materials for the knife include stainless steel, ceramic, or plastic. Of course, it can also be made from other suitable materials.

[0070] The knives are sharpened in the usual way, in the direction of the cut.

[0071] The knife can be equipped with teeth along its entire length, sharpened on all sides, allowing even softer foods to be processed without compromising the desired result. This is because a solid, flat blade, without sharp teeth, exerts pressure on the food when pulling the knife. This makes it possible to process foods like meat, loaf cakes, and many other similarly textured products with this tool. A blade that makes full contact with certain foods compresses the food as it passes through, resulting in crushing and tearing. This is prevented by the very sharp, longer teeth on the blade.

[0072] To facilitate the removal of the hollowed-out pieces from the food, in one embodiment a washer, approximately the same size as the blade running along the outside of the support beam, can be applied to the support beam after the blade has been pulled out of the food using the pulling device. This washer is attached to the support beam in one embodiment by means of an external thread on the support beam and an internal thread in the hole of the washer.

[0073] When this unit, consisting of the disc and support beam, is pulled backward out of the food, the disc forms a pressure surface which, when pulled, exerts pressure on the resulting hollow, i.e., the cutout in the food. The pulling force can thus be transferred more effectively to the cutout. The cutout is then pulled out.

[0074] To protect the user's hand during the pulling process with the knife through the food, a plastic disc with a central hole, larger in diameter than the knife, is slid onto the tool after the food has been pierced as intended. This disc is placed on the tool before pulling. The user can then grasp the protruding part of the tool with one hand, ensuring the disc is in direct contact with the food, and pull the knife through the food with the other hand until the knife strikes the plastic disc when fully inserted. This protective mechanism allows for quick pulling without risk of injury from the blade. The disc can also be made of materials other than plastic.In another form, the disc can also have a U-shape and not be slid on but only placed over the frame, as this is faster.

[0075] In one embodiment, pulling at the tip can be facilitated by having the tip have a through hole at a right angle to the actual point. After the food has been pierced, a pulling ring can be inserted through this hole, which is then grasped with a finger to pull the pulling device through the food.

[0076] In another embodiment, a sleeve precisely matching the dimensions of the knife can be pulled into the food behind the knife. This makes it possible, in a single step, to pull the knife through the food and guide the sleeve attached to the knife precisely into the opening created by the knife in the food. The sleeve is thus pulled directly behind the knife. The sleeve is then filled with the food. Using sleeves made of durum wheat semolina or other starch, a pre-filled sleeve containing the respective food can be obtained.

[0077] In one embodiment, the connection between the blade and the sleeve is achieved by providing the blade with grooves at its end, i.e., opposite the sharp, cutting edge. These grooves can range from recesses to through holes. The sleeves must also have these grooves or holes along their edges. The secure connection between the blade and the sleeve is achieved using a thin spring steel strip, approximately 5 cm long and corresponding to the dimensions of the blade. This spring steel strip has a continuous slot along its entire length. In the case of a circular blade, this spring steel strip is also bent into a circular shape and is elongated like a tube. The slot is wide enough to generate sufficient tension when the spring steel strip is compressed, allowing it to be inserted into the circular blade (in one embodiment).The spring plate has stamped marks or raised sections at the points where the knife has its grooves or holes. These sections engage in the grooves or holes of the knife when the spring plate is no longer compressed by finger pressure. The spring plate also has these stamped marks or raised sections at its other end, which engage in the same way with the sleeve, which is circular and has the same dimensions as the knife. The knife and sleeve are connected by the spring plate, located in the cavity or interior of the knife and sleeve, through the tension created by the released spring plate. This ensures that the connection remains even when the blade is inserted into or through the food. The rectangular knife, which later runs in the slot of the support bar, does not interfere with this, as it must be positioned within the slot of the spring plate. The sleeve, like the knife, is guided through or into the food along the outside of the support bar.The sleeve must exactly match the dimensions of the knife it follows. This is particularly feasible with softer foods.

[0078] This tool enables a process to hollow out many types of food, especially vegetables, fruits, and sausages, across their entire dimension or length, to fill them with other foods as desired, or to use the respective hollowed-out contents to fill the hollowed-out foods against each other.

[0079] This method relies on a blade guide guided by a support bar during the cutting process through the food. For this purpose, the pulling device with the blade is inserted into the support bar so that the square blade runs in the slot of the support bar. Since the support bar is open at both ends, insertion can be performed from either side, as the tip is detachable in one embodiment and can also be attached after insertion as described. The food is then pierced with the tip leading. The blade runs through the support bar guide, and by pulling on the tip, the pulling device guides it precisely along the path of the support bar, through the food. In one embodiment, pulling on the tip is facilitated by a hole in the tip perpendicular to the cutting direction, through which a pulling ring is hooked.After piercing the food, the knife can be pulled out using the pull mechanism, along with the pull mechanism at the other end of the support bar, while the support bar remains in the food. The desired hollowed-out area, corresponding to the knife's dimensions, can then be removed using the support bar.

[0080] However, there is another exciting possibility: attach a different-sized blade to the extended puller mechanism, while the first hollowed-out piece and the support shaft remain inside the food. The puller mechanism, without its tip, is then inserted into the support shaft. Once it protrudes from the other end of the shaft, the blade (the one attached to the puller mechanism) is used to pull the mechanism through the food again. The tip can be unscrewed and the pull ring used for this. The result is two different hollowed-out pieces, one on top of the other, inside a single piece of food. This creates exciting hollowed-out pieces that can be filled with pieces from other foods. You can effortlessly create a zucchini filled with sausage, cucumber, or potato.If a knife of another dimension is not only circular but star-shaped or wave-shaped, absolutely creative results are created.

[0081] In another embodiment, as described, it is also possible to draw a sleeve made of food starch or durum wheat semolina into the food behind the knife and thereby fill the sleeve with the hollowed-out product of the knife. Erklärung der Figuren:
