[0002] Protein flakes are mainly made from plant proteins extracted from crops such as soybeans, peas, and wheat. They use chemical separation to first extract the plant protein needed by the human body from the raw materials, and then go through a series of steps such as heating, extrusion, cooling, and shaping.

[0003] In the preparation of protein flakes, extrusion molding is one of the important processes. In order to ensure the molding quality of protein flakes, a molding die is usually set on the extruder. The raw materials pass through the molding die under the extrusion of the extruder and are then molded into flakes under the action of the molding die.

[0004] At present, most existing forming molds are of one-piece forming design, with a forming cavity opened in the middle of the cylindrical mold, and the raw material is extruded into a thin sheet under the guidance of the forming cavity in the mold.

[0005] With respect to the above-mentioned related technologies, the inventors found that when the protein slices are extruded, they can only be extruded outward in the form of a single strip, which has the defect of low efficiency in extrusion molding of the protein slices. Summary of the Invention

[0009] By adopting the above technical solution, multiple discharge cavities are set between the outer mold cylinder and the inner mold cylinder. When producing protein slices, the forming mold is installed on the extruder. The material will be pressed into the flow channel between the outer mold cylinder and the inner mold cylinder under the action of the extruder, and then the material will continue to be extruded.

[0012] Preferably, the flow channel gradually becomes thinner along the material flow direction, and the thinness of the discharge end of the flow channel is equal to the thinness of the discharge end.

[0013] By adopting the above technical solution and utilizing the gradual setting of the flow channel, the material will be gradually compressed and organized after entering the flow channel, and will eventually form a filamentous sheet, thereby improving the forming quality of the sheet.

At the same time, the vibration mechanism is started to vibrate the material in the forming mold, so that the material is compacted and sinks in the forming mold, and then extruded upward, thereby improving the density of the sheet and thus improving the quality of the sheet.

The outer die barrel 100 is coaxially sleeved on the outer side of the inner die barrel 200. A flow channel 210 is formed between the inner wall of the outer die barrel 100 and the outer wall of the inner die barrel 200, and the material can flow in the flow channel 210. A diverter ring 220 is coaxially provided on the inner die barrel 200. The diverter ring 220 is located near the feeding end of the inner die barrel 200.

A plurality of diverter holes 230 are formed on the end surface of the diverter ring 220. The plurality of diverter holes 230 are connected to the flow channel 210.

A plurality of discharge cavities 240 are provided at the end of the inner mold barrel 200 away from the diverter ring 220. Each discharge cavity 240 is provided on the side wall of the inner mold barrel 200. The plurality of discharge cavities 240 are spaced apart with the axis of the inner mold barrel 200 as the center of the circle, and each discharge cavity 240 is connected to the flow channel 210. When preparing the protein slices, the forming mold is installed on the extruder, and the extruder is started. Under the extrusion of the extruder, the material enters the flow channel 210 through the plurality of diverter holes 230, and then is extruded and formed through the plurality of independent discharge cavities 240, thereby realizing the synchronous extrusion molding of multiple slices, thereby improving the extrusion molding efficiency of the slices.

[0046] The implementation principle of a sheet extrusion molding die in the embodiment of the present application is as follows: by setting multiple discharge cavities 240 between the outer die cylinder 100 and the inner die cylinder 200, when the protein sheet needs to be extruded, the molding die is installed on the extruder, and then the material is pressed into the mold under the action of the extruder, and then the material is extruded and molded from multiple independent discharge cavities 240, realizing the synchronous extrusion of multiple sheets, improving the extrusion molding efficiency of the sheet

[0047] Example 2

[0048] Reference Figure 4 and Figure 5 In order to improve the applicability of the forming mold, an adjusting mechanism 300 is provided on the inner mold cylinder 200. The adjusting mechanism 300 includes a plurality of adjusting blocks 310. The plurality of adjusting blocks 310 are arranged in a one-to-one correspondence with the plurality of discharge cavities 240. Each adjusting block 310 is penetrated on the side wall of its corresponding discharge cavity 240. Each adjusting block 310 is slidably connected to the inner mold cylinder 200. A power component 320 is installed on the inner mold cylinder 200. The power component 320 is used to drive the plurality of adjusting blocks 310 to slide synchronously.

[0049] Reference Figure 4 and Figure 5The power assembly 320 includes a first motor 321 fixedly connected to the interior of the inner mold cylinder 200. The main shaft of the first motor 321 is coaxially fixedly connected to a worm 322. The worm 322 is rotatably connected to the inner mold cylinder 200. A worm gear 323 is rotatably connected to the inner mold cylinder 200. The rotation axis of the worm gear 323 is colinear with the axis of the inner mold cylinder 200. The worm 322 and the worm gear 323 are meshed. Each control block 310 is fixedly connected to a connecting rod 324. The end of the connecting rod 324 away from the control block 310 to which it is fixed is fixedly connected to the worm gear 323. When it is necessary to produce thin sheets with gradually changing widths, the first motor 321 is started at the same time during the extrusion molding process of the thin sheets. The first motor 321 is used to drive the worm 322 to rotate, thereby driving the worm gear 323 to rotate. The rotation of the worm gear 323 will drive the multiple control blocks 310 to slide synchronously through the multiple connecting rods 324, so that the size of the discharge cavity 240 can change with the sliding of the control block 310, thereby realizing the change of the width of the thin sheet, thereby producing thin sheets with gradually changing widths; when it is necessary to produce thin sheets of other widths, the control block 310 is directly controlled to move to the corresponding position, and then the material can be extruded, so that the staff can adjust the width of the discharge cavity 240 according to different needs, thereby improving the applicability of the mold.

[0050] The present application also provides an extruder, including the above-mentioned forming die, with reference to Figure 6 and Figure 7 The extruder includes a frame 400, to which an extrusion barrel 410 is fixedly connected. The extrusion barrel 410 is arranged horizontally. A feed hopper 420 is fixedly connected to the extrusion barrel 410, and the material enters the extrusion barrel 410 through the feed hopper 420. An extrusion mechanism 430 is installed on the frame 400, and the extrusion mechanism 430 includes a reduction motor group 431 fixedly connected to the frame 400. Two screws are rotatably connected in the extrusion barrel 410. The two screws are arranged in parallel and connected by gear transmission. The reduction motor group 431 is connected to one of the screws. The reduction motor group 431 drives the two screws to rotate to realize the extrusion and transportation of the material. The forming mold is installed at the discharge end of the extrusion barrel 410. Add materials into the extruder through the feed hopper 420, then start the reduction motor group 431, and use the reduction motor group 431 to drive the two screws to rotate to extrude and transport the material in the extrusion barrel 410, and then allow the material to enter the forming mold and then be discharged from the discharge cavity 240 of the forming mold to achieve extrusion molding of the sheet.

[0051] Reference Figure 6 and Figure 7A vibration mechanism 500 is installed on the molding mold. The vibration mechanism 500 includes a pulling assembly 510 and multiple groups of vibration members 520. The multiple groups of vibration members 520 are arranged at intervals along the circumference of the outer mold cylinder 100. Each group of vibration members 520 includes a fixed plate 521 fixedly connected to the outer mold cylinder 100. The fixed plate 521 is arranged in a direction perpendicular to the axis of the outer mold cylinder 100. A spring 522 is installed on the fixed plate 521. One end of the spring 522 is fixedly connected to the fixed plate 521, and the other end of the spring 522 is fixedly connected to the knocking ball 523. The knocking ball 523 abuts against the outer wall of the outer mold cylinder 100 under the push of the spring 522.

[0052] The pulling assembly 510 includes a pulling ring that is sleeved on the outside of the outer mold cylinder 100. The pulling ring is slidably connected to the outer mold cylinder 100 and slides along the length of the outer mold cylinder 100. A pull rope 512 is fixedly connected to the side of each knocking ball 523 facing away from the outer mold cylinder 100. The end of the pull rope 512 away from the knocking ball 523 passes through a spring 522 and a fixed plate 521 and is fixedly connected to the pulling ring. Two second motors 513 are fixedly connected to the outer mold cylinder 100. The two second motors 513 are respectively located on opposite sides of the outer mold cylinder 100. The main shaft of each second motor 513 is fixedly connected to a cam 514. The second motor 513 drives the cam 514 to rotate to drive the pulling plate 511 to slide. A notch is opened on one side of the cam 514, making the cam 514 have a "," shape. When the material is extruded, since the thickness of the extruded protein slices is relatively thin, it is necessary to ensure that the material has sufficient density in the molding mold. By using the setting of multiple vibrating parts 520, during the extrusion molding process of the slices, the two second motors 513 are started at the same time. The two second motors 513 drive the two cams 514 to rotate and push the pulling plate 511 to slide. The sliding of the pulling plate 511 will pull the multiple knocking balls 523 to slide through the pull rope 512. When the cam 514 pushes the cam 514 to move to the maximum position, the cam 514 continues to rotate. Due to the setting of the notch, the pulling plate 511 will quickly move back under the pull of multiple springs 522. At the same time, the spring 522 will push the knocking ball 523 connected to it to collide with the outer mold cylinder 100, so that the material is vibrated in the molding mold, the density of the slice is improved, and the quality of the slice is improved.

[0053] The implementation principle of a thin film extrusion molding die and an extruder using the die in an embodiment of the present application is as follows: by slidingly connecting multiple control blocks 310 in an inner mold cylinder 200, during the extrusion molding process of the thin film, the first motor 321 is used to drive the worm 322 to rotate, which can drive the worm gear 323 to rotate. Since the worm gear 323 and the inner mold cylinder 200 are coaxially arranged, the rotation of the worm gear 323 will drive the multiple control blocks 310 to slide synchronously, and during the thin film extrusion process, the width of the discharge cavity 240 is adjusted to produce thin films with a gradual width, thereby realizing the change of the thin film width and improving the applicability of the molding die; at the same time, by utilizing the setting of the vibration mechanism 500, during the extrusion process of the thin film, multiple knocking mechanisms are simultaneously driven to knock and vibrate the material in the molding die, thereby improving the density of the molded thin film and improving the molding quality of the thin film with a gradual width.

[0054] Example 3

[0055] Reference Figure 7 and Figure 8 This embodiment provides an extruder, which differs from the extruder in Example 2 in that a guide cylinder 600 is rotatably connected to the discharge end of the receiving cylinder. The guide cylinder 600 is bent upward at 90 degrees. One end of the guide cylinder 600 is connected to the extrusion cylinder 410, and the forming mold is fixedly connected to the end of the guide cylinder 600 away from the extrusion cylinder 410. The guide cylinder 600 is provided with a plurality of guide holes, each of which is provided along the length of the guide cylinder 600 and passes through the front and rear ends of the guide cylinder 600. The plurality of guide holes are provided in a one-to-one correspondence with the plurality of diverter holes 230, and the guide holes are connected to their corresponding diverter holes 230.

[0056] The extrusion barrel 410 is equipped with a drive mechanism 700. The drive mechanism 700 includes a third motor 710 fixedly connected to the extrusion barrel 410. The main shaft of the third motor 710 is coaxially fixedly connected to a first gear 720. The guide barrel 600 is coaxially fixedly connected to a second gear 730. The first gear 720 and the second gear 730 are meshed and connected. When the guide barrel 600 is rotated and connected to the extrusion barrel 410, the third motor 710 is used to drive the guide barrel 600 to rotate, causing the guide barrel 600 to bend upward. Then, the outer die barrel 100 is struck and vibrated, so that the material can be vibrated downward in the forming mold, further improving the compactness of the material. After the thin film is extruded to a certain length, the drive mechanism 700 is activated and driven by the drive mechanism 700 to rotate the guide barrel 600, causing the guide barrel 600 to bend downward. Then, the material is extruded again. This can improve the continuity of the extruded thin film and prevent the thin film from breaking. The rotation frequency of the guide barrel 600 can be adjusted according to different needs.

[0057] The implementation principle of an extruder in an embodiment of the present application is as follows: by rotating the guide cylinder 600 and connecting it to the extrusion cylinder 410, during the extrusion process of a thin sheet with a gradually changing width, when the regulating block 310 moves back to expand the discharge cavity 240, it is easy to cause the hardness of the edge of the extruded thin sheet to decrease. At this time, the guide cylinder 600 is rotated to a vertical state, and the vibration mechanism 500 is used to vibrate the material in the forming mold downward to improve the strength of the extruded thin sheet. After vibrating the material in the extrusion cylinder 410, the forming mold is controlled to rotate downward, and then the material is extruded, so that the thin sheet is not easy to break.

[0058] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
