Description

Technical Field

[0001] The present invention relates to the technical field of protein vegetarian meat processing, and in particular to a composite plant protein vegetarian meat extrusion and puffing device and a method thereof. Background Art

[0002] Protein meat, also known as soy protein or artificial meat, is a protein product that highly imitates the shape, color and taste of meat. Its processing equipment, such as the patent with the announcement number CN113261691B in my country, discloses an extruder extrusion mechanism that reduces the screw damage rate. This device increases the friction of the material during movement, thereby increasing the temperature of the material, evaporating the water, and increasing the air pressure in the cavity, thereby increasing the expansion degree of the material when it is discharged and improving the expansion effect of the material. However, the above technology also has the following defects:

[0003] Most of the current extrusion and puffing devices are composed of a threaded rod and a cylindrical shell, wherein the threaded rod rotates in the cylindrical shell, and the threaded rod is used to drive the viscous material in the cylindrical shell to move forward. In the process of the viscous material passing through the end of the cylindrical shell, the viscous material will be heated and dehydrated and gradually become a paste material, and finally the paste material will be extruded from the extrusion cavity. After the paste material is extruded, due to the low external pressure and temperature, the paste material will expand after the pressure and temperature drop sharply, and finally form an expanded material, wherein the threaded rod drives the viscous material to continuously move forward to extrude the paste material, but when the viscous material is completely injected into the cylindrical shell, as the viscous material in the cylindrical shell continues to become a paste material and expand and discharge, the last part of the paste material will no longer be compressed after passing through the threaded rod, so at the final stage of extrusion and puffing, a part of the paste material that cannot be extruded and discharged will remain in the extrusion cavity, and the paste material remaining in the extrusion cavity will gradually dry and block the extrusion cavity.

DETAILED DESCRIPTION

[0036] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0037] refer to Figures 1 to 12The composite plant protein vegetarian meat extrusion and puffing equipment shown in the figure includes a spiral extrusion component, a rotary cutting component and a secondary extrusion component. The spiral extrusion component includes a columnar shell 1, a threaded rod 2 and an extrusion card seat. The columnar shell 1 is horizontally arranged, and the threaded rod 2 coaxially rotates in the columnar shell 1. The two ends of the columnar shell 1 are a closed end and an open end respectively. The columnar shell 1 is provided with a feed pipe 3 close to its closed end. The extrusion card seat is arranged on the open end of the columnar shell 1. An extrusion cavity 4 connected to the inner cavity of the columnar shell 1 is provided in the extrusion card seat. One end of the extrusion card seat is provided with a plurality of discharge holes 5 connected to the extrusion cavity 4. The rotary cutting component It is arranged on the extrusion card seat, and the secondary extrusion assembly is arranged in the extrusion cavity 4. The secondary extrusion assembly includes a reciprocating screw rod 6, an extrusion block 7, an extrusion ring 8 and a one-way rotating connector. The reciprocating screw rod 6 is horizontally connected to the extrusion card seat for rotation. The one-way rotating connector connects the reciprocating screw rod 6 to the threaded rod 2. The extrusion ring 8 is arranged in the extrusion cavity 4. The extrusion ring 8 is elastically connected to the extrusion card seat, and the reciprocating screw rod 6 passes through the extrusion ring 8. The extrusion block 7 is rotated on the reciprocating screw rod 6. The extrusion block 7 and the extrusion ring 8 are distributed at intervals along the axial direction of the reciprocating screw rod 6, and the extrusion ring 8 is close to the extrusion card seat, and the extrusion block 7 is close to the threaded rod 2. A notch 9 is provided on the extrusion ring 8 (such as Fig.11 As shown in the figure), a blocking block 10 which fits with the notch 9 is provided on the extrusion block 7.

[0038] Protein meat, also known as soy tissue protein, is mainly made of soybeans. Before extrusion and puffing, the ground soybeans and water need to be mixed in proportion, and then the resulting viscous material is injected into the columnar shell 1 through the feed pipe 3. When the viscous material enters the columnar shell 1, the threaded rod 2 starts to rotate, and the viscous material is driven by the threaded rod 2 to move toward the extrusion cavity 4. In actual use, the columnar shell 1 is provided with a plurality of external heating chambers (not shown in the figure) equidistantly distributed along its axial direction. In the process of displacement of the viscous material, the viscous material will The viscosity is increased by heat dehydration and finally a paste is formed. When the paste moves to the vicinity of the extrusion cavity 4, the paste passes through the extrusion ring 8 and the notch 9 on the extrusion ring 8 after passing through the extrusion block 7 and enters the extrusion cavity 4. Thereafter, as the subsequent viscous material is continuously injected, the rotating threaded rod 2 drives the viscous material to extrude the front paste from the plurality of discharge holes 5 on the extrusion card seat. When the paste is extruded from the discharge hole 5, the paste will expand immediately due to the sudden drop in pressure and temperature, and finally the expanded material extruded from the discharge hole 5 will be cut off by the rotary cutting assembly.

[0039] In actual use, the threaded rod 2 drives the viscous material to continuously move forward to extrude the paste material. However, when all the viscous material is injected into the columnar shell 1, as the viscous material in the columnar shell 1 continuously turns into a paste material and expands and is discharged, the last part of the paste material will no longer be compressed after passing through the threaded rod 2. Therefore, at the final stage of extrusion and expansion, a part of the paste material that cannot be squeezed out will remain in the extrusion chamber 4. At this time, in order to prevent the paste material from drying and blocking the extrusion chamber 4, the device is provided with a secondary extrusion component in the extrusion chamber 4. The specific working process of the secondary extrusion component is as follows: in the process of the threaded rod 2 rotating forward to drive the viscous material forward, the reciprocating screw rod 6 will not rotate through the unidirectional rotating connecting piece. When the paste material remaining in the extrusion chamber 4 needs to be discharged, the control When the threaded rod 2 rotates in the opposite direction, the reciprocating screw 6 will rotate along with the threaded rod 2 through the one-way rotating connector. At this time, the extrusion block 7 rotated on the reciprocating screw 6 will start to translate toward the extrusion ring 8 along the axial direction of the reciprocating screw 6. When the extrusion block 7 and the extrusion ring 8 are merged, the blocking block 10 is embedded in the notch 9. Thereafter, the extrusion block 7 will drive the extrusion ring 8 to move forward together, so that the paste material remaining in the extrusion cavity 4 is squeezed out from the plurality of discharge holes 5 through the merged extrusion block 7 and the extrusion ring 8. When the extrusion block 7 and the extrusion ring 8 are close to the plurality of discharge holes 5, the extrusion block 7 will immediately translate in the opposite direction through the action of the reciprocating screw 6. At this time, the extrusion ring 8 that loses the thrust of the extrusion block 7 will gradually reset itself through elasticity. Finally, the extrusion block 7 and the extrusion ring 8 will both move in the opposite direction to the initial state.

[0040] To show how the threaded rod 2 is installed in the cylindrical housing 1, the following features are provided:

[0041] A bearing 11 is embedded in the closed end of the cylindrical shell 1. The threaded rod 2 includes a roller 12, a rotating shaft 13 and a spiral blade 14. The roller 12 is coaxially arranged in the cylindrical shell 1. The rotating shaft 13 is coaxially fixedly connected to one end of the roller 12, and the rotating shaft 13 passes through the bearing 11. The spiral blade 14 is arranged on the outer wall of the roller 12, and the spiral blade 14 extends spirally along the axial direction of the roller 12.

[0042] The roller 12 is rotated by the shaft 13 passing through the bearing 11. When the roller 12 rotates, the roller 12 drives the spiral blade 14 to rotate, and the spiral blade 14 drives the viscous material in the columnar housing 1 to move forward. In actual use, one end of the columnar housing 1 is provided with an external motor (not shown in the figure) for driving the shaft 13 to rotate.

[0043] In order to show the specific structure of the extrusion card holder, the following features are set:

[0044] The extrusion card seat includes a columnar seat body 15 and a circular cover plate 16. One end of the columnar seat body 15 is coaxially fixedly connected to the open end of the columnar shell 1. The extrusion cavity 4 is opened in the columnar seat body 15, and the extrusion cavity 4 penetrates the end of the columnar seat body 15 toward the columnar shell 1. The end of the columnar seat body 15 away from the columnar shell 1 is provided with a mounting port 17, and the mounting port 17 is connected to the extrusion cavity 4 (such as Fig.12 As shown in the figure, the circular cover plate 16 is fixed on the installation opening 17, and the circular cover plate 16 covers the installation opening 17, and a plurality of discharge holes 5 are arranged on the circular cover plate 16.

[0045] When the viscous material in the columnar shell 1 is heated and dehydrated to form a paste, the paste will enter the extrusion cavity 4 in the columnar base 15 from the columnar shell 1. With the continuous injection of subsequent viscous material and the rotation drive of the threaded rod 2, the paste in the extrusion cavity 4 will be pressed out through the multiple discharge holes 5 on the circular cover plate 16.

[0046] In order to facilitate the extrusion of the paste from the plurality of discharge holes 5, the following features are provided:

[0047] One end of the extrusion cavity 4 close to the installation opening 17 tapers to form a conical cavity 18. A conical ring 19 capable of being engaged with the conical cavity 18 is formed on the side of the extrusion ring 8 facing the circular cover plate 16. The notch 9 provided on the extrusion ring 8 passes through the conical ring 19.

[0048] After the paste enters the extrusion chamber 4, with the continuous injection of subsequent viscous material and the rotation drive of the threaded rod 2, the paste entering the extrusion chamber 4 will be squeezed toward the conical chamber 18, and the conical chamber 18 will concentrate the paste to the several discharge holes 5 on the circular cover plate 16. When the paste in the extrusion chamber 4 is extruded for the second time, the combined extrusion ring 8 and the extrusion block 7 will press the paste in the extrusion chamber 4 toward the circular cover plate 16. During this process, the conical ring 19 provided on the extrusion ring 8 will gradually fit into the conical chamber 18, so that the conical ring 19 will press the paste in the extrusion chamber 4 into the conical chamber 18.

[0049] In order to show how the extrusion ring 8 is installed on the extrusion card seat, the following features are set:

[0050] Two symmetrical truncated cones 20 are fixedly disposed on the conical cavity 18, and each truncated cone 20 is formed with a horizontal fixing rod 21 (such as Figure 8As shown), the conical ring 19 is provided with two No. 1 cylindrical grooves 22 corresponding to the fixing rods 21, and the extrusion ring 8 is provided with two No. 2 cylindrical grooves 23 corresponding to the No. 1 cylindrical grooves 22. Each No. 2 cylindrical groove 23 is connected with the corresponding No. 1 cylindrical groove 22, and the inner diameter of each No. 1 cylindrical groove 22 is larger than the inner diameter of the No. 2 cylindrical groove 23. One end of each fixing rod 21 passes through the No. 1 cylindrical groove 22 and the No. 2 cylindrical groove 23 in sequence. Each fixing rod 21 is sleeved with a No. 1 spring 24, and the two ends of the No. 1 spring 24 respectively conflict with the inner wall of the No. 1 cylindrical groove 22 and the frustum 20. A limiting cap 25 is fixed to one end of each fixing rod 21 passing through the extrusion ring 8.

[0051] In the initial state, the No. 1 spring 24 drives the extrusion ring 8 and the conical ring 19 to translate toward the extrusion block 7 through elastic force. Finally, the outer wall of the extrusion ring 8 will conflict with the two limit caps 25. The limit caps 25 are used to limit the translation stroke of the extrusion ring 8. When the extrusion block 7 and the extrusion ring 8 are merged, the extrusion block 7 will drive the extrusion ring 8 to move together. In this process, the extrusion ring 8 will synchronously compress the two No. 1 springs 24, so that the No. 1 spring 24 will be compressed to generate elastic force. Then, when the extrusion block 7 translates in the opposite direction, the extrusion ring 8 will be driven to translate in the opposite direction by the elastic force of the No. 1 spring 24 until it is reset.

[0052] In order to specifically show how the extrusion block 7 translates, the following features are set:

[0053] The extrusion block 7 is circular, and a threaded sleeve 26 (combined with the thread of the reciprocating screw rod 6) is fixed at the center of the extrusion block 7. Figure 3 and Fig.11 ), a convex ring 27 is formed on one end of the extrusion block 7 facing the threaded rod 2, and a plurality of limiting rods 28 are formed on the side of the extrusion ring 8 facing the extrusion block 7, each limiting rod 28 is horizontal, and a plurality of slots 29 corresponding to the limiting rods 28 are formed on the convex ring 27, and one end of each limiting rod 28 is inserted into the corresponding slot 29.

[0054] A plurality of limit rods 28 are used to limit the displacement of the extrusion block 7, ensuring that the extrusion block 7 can only translate along the axial direction of the reciprocating screw 6. When the reciprocating screw 6 rotates, the extrusion block 7 translates through the threaded sleeve 26 screwed on the reciprocating screw 6. When the extrusion block 7 translates, each limit rod 28 slides in the corresponding slot 29. When the extrusion block 7 approaches the extrusion ring 8, the entire extrusion block 7 is inserted into the extrusion ring 8. Thereafter, the convex ring 27 contacts the extrusion ring 8, and the extrusion ring 8 is driven to translate by the convex ring 27 contacting the extrusion ring 8. At the same time, the blocking block 10 provided on the extrusion block 7 is inserted into the notch 9 on the extrusion ring 8. Fig.11As shown, a slope that can fit with the tapered ring 19 is formed on one side of the blocking block 10 , so that when the blocking block 10 is inserted into the notch 9 , a complete tapered surface that can fit with the tapered cavity 18 is formed on the tapered ring 19 .

[0055] In order to show the specific structure of the one-way rotating connector, the following features are set:

[0056] The one-way rotating connecting member includes a first disc 30, a second disc 31 and an elastic member. The end of the roller 12 close to the extrusion block 7 is provided with a receiving groove 32 (such as Figure 4 As shown in the figure, the No. 1 disc 30 is fixed in the receiving groove 32, one end of the reciprocating screw rod 6 extends into the receiving groove 32, the No. 2 disc 31 is slidably connected to the end of the reciprocating screw rod 6 inserted into the receiving groove 32, the elastic member is arranged beside the No. 2 disc 31, and a plurality of No. 1 bevel teeth 33 (as shown in the figure) are formed on the surface of the No. 1 disc 30 facing the No. 2 disc 31 Fig. 9 As shown in the figure, a plurality of No. 1 bevel teeth 33 are evenly distributed along the circumferential direction of the No. 1 disc 30, a plurality of No. 2 bevel teeth 34 are formed on the side of the No. 2 disc 31 facing the No. 1 disc 30, and a plurality of No. 2 bevel teeth 34 are evenly distributed along the circumferential direction of the No. 2 disc 31, and a plurality of No. 1 bevel teeth 33 and a plurality of No. 2 bevel teeth 34 are meshed with each other.

[0057] The structure of the No. 1 beveled tooth 33 and the No. 2 beveled tooth 34 is the same, both of which contain a straight surface and a beveled surface. When the roller 12 rotates in the positive direction to drive the viscous material to move forward, the No. 1 disc 30 will rotate along with the roller 12. At this time, the beveled surface of each No. 1 beveled tooth 33 will slide on the beveled surface of the No. 2 beveled tooth 34, so that the No. 2 disc 31 will not rotate. At this time, the No. 2 disc 31 will translate due to the interference of several No. 1 beveled teeth 33. When the No. 2 disc 31 is displaced, the No. 2 disc 31 will rotate. The No. 1 disc 31 will compress the elastic member and cause the elastic member to generate elastic force, so that the No. 2 disc 31 can be always pressed toward the No. 1 disc 30 through the elastic member. When the roller 12 rotates in the opposite direction, the No. 1 disc 30 will drive a number of No. 1 bevel teeth 33 to rotate in the opposite direction. During this process, the straight surface on each No. 1 bevel tooth 33 will conflict with the straight surface on the corresponding No. 2 bevel tooth 34, so that the No. 1 disc 30 will drive the No. 2 disc 31 to rotate, and finally the reciprocating screw 6 will be driven to rotate by the No. 2 disc 31.

[0058] In order to show the specific structure of the elastic part, the following features are set:

[0059] A plurality of strip slide grooves 35 are provided on one end of the reciprocating screw 6 that passes through the accommodating groove 32. The plurality of strip slide grooves 35 are evenly distributed along the circumferential direction of the reciprocating screw 6. A circular groove 36 sleeved on the reciprocating screw 6 is provided at the center of the circle of the No. 2 disk 31. A plurality of slide bars 37 corresponding to the strip slide grooves 35 are formed in the circular groove 36. Each slide bar 37 slides in the corresponding strip slide groove 35 along the axial direction of the reciprocating screw 6. The elastic member includes a No. 2 spring 38 and a retaining ring 39. The retaining ring 39 is located on the side of the No. 2 disk 31, and the retaining ring 39 is coaxially formed on the outer wall of the reciprocating screw 6. The No. 2 spring 38 is sleeved on the reciprocating screw 6, and the two ends of the No. 2 spring 38 respectively conflict with the retaining ring 39 and the No. 2 disk 31.

[0060] When the roller 12 drives the No. 1 disk 30 to rotate in the forward direction, the No. 2 disk 31 will be resisted by a number of No. 1 bevel teeth 33, so that the No. 2 disk 31 will be displaced and compress the No. 2 spring 38. During this process, each slide bar 37 provided on the No. 2 disk 31 will slide in the corresponding bar slide groove 35, and the No. 2 disk 31 will be translated by the cooperation between the slide bar 37 and the bar slide groove 35. When the roller 12 drives the No. 1 disk 30 to rotate in the reverse direction, the No. 1 disk 30 will drive the No. 2 disk 31 to rotate.

[0061] In order to show the specific structure of the peeling component, the following features are set:

[0062] The peeling assembly includes a mounting shell 40, a rotating pin 41, a driving motor 42 and a plurality of peeling knives 43. The mounting shell 40 is cylindrical and coaxially fixed on one end of the cylindrical seat body 15 (such as Figure 6 As shown, a circular partition 44 is coaxially formed in the mounting shell 40, and the circular partition 44 divides the cavity in the mounting shell 40 into a discharge cavity 45 and a receiving cavity 46 (as shown in FIG. Figure 7 As shown), the discharge cavity 45 is close to the circular cover plate 16, and a discharge port 47 connected to the discharge cavity 45 is opened on the outer wall of the mounting shell 40.

[0064] A method for extruding and puffing composite plant protein vegetarian meat, the method comprising the following steps:

[0065] S1, injecting the mixture of soybean powder and water into the columnar housing 1 through the feed pipe 3;

[0066] Protein meat, also known as soy tissue protein, is mainly made of soybeans. Before extrusion and puffing, the ground soybeans and water need to be stirred and mixed in proportion, and then plant powder is added to the mixture. Finally, the resulting viscous material is injected into the columnar shell 1 through the feed pipe 3.

[0067] S2, controls the threaded rod 2 to rotate forward;

[0068] The threaded rod 2 drives the viscous material to move toward the extrusion chamber 4. In actual use, the cylindrical shell 1 is provided with a plurality of external heating chambers (not shown in the figure) equidistantly distributed along its axial direction. Then, in the process of displacement of the viscous material, the viscous material will be heated and dehydrated to increase the viscosity and finally form a paste. When the paste moves close to the extrusion chamber 4, the paste will enter the extrusion chamber 4 through the extrusion ring 8 and the notch 9 on the extrusion ring 8 after passing through the extrusion block 7. Thereafter, with the continuous injection of subsequent viscous material, the rotating threaded rod 2 will drive the viscous material to extrude the paste in front from the plurality of discharge holes 5 on the extrusion card seat. When the paste is extruded from the discharge hole 5, the paste will immediately expand due to the sudden drop in pressure and temperature.

[0069] S3, start the rotary cutting component;

[0070] The expanded material extruded from the discharge hole 5 is cut off by the rotary cutting assembly.

[0071] S4, controlling the threaded rod 2 to rotate in the opposite direction.

[0072] The threaded rod 2 is controlled to rotate in the opposite direction, and the reciprocating screw 6 will rotate along with the threaded rod 2 through the one-way rotating connector. At this time, the extrusion block 7 rotated on the reciprocating screw 6 will start to translate toward the extrusion ring 8 along the axial direction of the reciprocating screw 6. When the extrusion block 7 and the extrusion ring 8 are merged, the blocking block 10 is embedded in the notch 9. Thereafter, the extrusion block 7 will drive the extrusion ring 8 to move forward together, so that the paste material remaining in the extrusion cavity 4 is squeezed out from the plurality of discharge holes 5 through the merged extrusion block 7 and the extrusion ring 8. When the extrusion block 7 and the extrusion ring 8 are close to the plurality of discharge holes 5, the extrusion block 7 will immediately translate in the opposite direction through the action of the reciprocating screw 6. At this time, the extrusion ring 8 that loses the thrust of the extrusion block 7 will gradually reset through elasticity, and finally the extrusion block 7 and the extrusion ring 8 will both move in the opposite direction to the initial state.
