Description

Technical Field

[0001] The utility model relates to a discharging device, in particular to a discharging device for adjusting the quality of soybean tissue filament protein and expanding the production capacity. Background Art

[0002] Extrusion puffing technology is an emerging soybean processing technology, and soy protein extrusion organization is a cutting-edge technology. Its purpose is to make plant protein have a fibrous structure similar to animal protein, so that the product is more easily accepted by consumers in terms of taste, texture, appearance, etc., and passivate the anti-nutritional factors in soy protein. It can not only improve the body's ability to digest and absorb protein and improve the nutritional value of soy protein, but also improve the functional characteristics of soy protein, making it more absorbent and oily.

[0003] Soybean textured protein can be produced through existing extrusion puffing technology, but stable control is difficult. During the extrusion process, the product temperature is difficult to maintain stable, and important production parameters such as temperature, pressure, and flow rate fluctuate greatly. The quality uniformity of the obtained product is poor, the production capacity is low, and the production cost is very high. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, the purpose of the utility model is to provide a discharging device for adjusting the quality and expanding the production capacity of soybean tissue filament protein. It is a new structure developed on the basis of existing equipment, so it can be applied to existing puffing extruder equipment to improve the stability of product output quality, and at the same time, it can also increase the output capacity.

[0005] The utility model provides the following technical solutions:

[0006] A discharging device for adjusting the quality and expanding the production capacity of soybean tissue drawing protein, comprising a flow diverter, a transition connection component, an extrusion cavity, a connecting rib plate, a mounting base and a forming die, wherein the flow diverter is connected to an extrusion barrel through a barrel end plate, and the extrusion cavity is provided with at least two groups, one end of which is connected to the flow diverter through the transition connection component, and the other end is connected to the forming die, each group of extrusion cavities comprises at least two sections of cavity units connected in modular combination, and the inner diameter of the fluid channel of the combined extrusion cavity gradually decreases from one end of the transition connection component to one end of the forming die; at this time, since the fluid channel in the entire extrusion cavity is designed to be a gradual change, when the raw material passes through this area, the fluid channel gradually becomes smaller, the extrusion is strengthened, the friction force is aggravated, the raw material protein is subjected to a large force, the surface charge is redistributed and tends to be uniform, the molecular structure is further stretched and reorganized, the secondary bonds such as hydrogen bonds and disulfide bonds between molecules are partially broken, the protein is rearranged, and the degree of protein organization is strengthened;

[0007] Each lumen unit includes a lumen inner wall, a lumen interlayer and a lumen outer sleeve. The lumen outer sleeve is connected to the outside of the lumen inner wall, and a lumen interlayer for accommodating a temperature-regulating fluid is formed between the lumen inner wall and the lumen interlayer. The lumen interlayer is connected to a mold temperature controller, and is used to regulate the temperature of the raw material in the lumen inner wall by the temperature of the inserted temperature-regulating fluid. The raw material temperature is adjusted steadily to keep the raw material stable in a very well organized state. The extrusion lumen temperature can support the organization of soy protein within a certain range, and will reduce the organization of soy protein when it exceeds a certain temperature. When the extrusion temperature is 130°C, the solubility of the raw material is very low. , the water holding capacity and water retention capacity are very small, the product has a good degree of organization, and has a more obvious fibrous structure. The extrusion temperature is in the range of 150-180℃, and the degree of organization increases with the increase of temperature. When the temperature is higher than 180℃, the organization begins to decrease. This is mainly because as the temperature rises, the material gradually becomes gelatinous, which is more conducive to protein denaturation. The protein is rearranged from the original disordered state to an orderly arrangement to form organized protein. However, as the temperature continues to rise, due to excess heat, the raw materials are easily "burned", which is not conducive to extrusion. Soy protein extrusion products need to have good thermal stability, so accurate temperature control is the most critical;

[0008] The connecting ribs are used to assist in the fixed connection of multiple groups of extrusion lumens to ensure the reliable mechanical rigidity of the components, and the forming mold is smoothly connected to the extrusion lumens through the mounting base. The forming mold can be designed into different shapes, such as columnar, flat, etc., according to product requirements. Each shape can be configured into different sizes according to product size requirements, such as columnar D12mm, D15mm; flat 5x35mm / 4x30mm, etc., wherein the flat forming mold gradually changes from a cylindrical shape to a flat outlet, and the inner surface of the gradient section is smooth and gentle. After the raw material passes through the forming mold, a continuous strip product in an organized state is obtained, which is further processed into a columnar or sheet product that meets the requirements through the downstream equipment traction device and cutting device.

[0009] Preferably, the diverter device includes a compression ring and a diverter block. The compression ring is provided with a conical surface, which is received at the tail end of the extruder barrel. It is used to collect the raw materials flowing out of the extrusion zone of the extruder barrel to the center through the conical surface, and then distribute the raw materials to the corresponding extrusion cavity tube through the diverter channel in the diverter block. The compression ring has multiple models to choose from according to different taper angles, which are used to adjust the pressure and flow rate of the raw material at the spiral outlet. The diverter block is configured with different models according to the number of diverter channels, and the specific designs include 2-hole diverter channels, 3-hole diverter channels, 4-hole diverter channels, etc.

[0010] Preferably, the transition connection assembly includes an outer ring and an inner plug-in, the outer ring is connected to the diverter block, and is provided with a transition hole corresponding to the diverter channel, the inner plug-in is installed in the transition hole, and is used to smoothly connect the diverter channel and the inner wall of the cavity tube, the outer ring is a part with a fixed size, and the inner hole size of the inner plug-in has multiple specifications, and its size is used to match the inner hole diameter of the extrusion cavity tube and the inner hole diameter of the diverter device to keep the raw material flow channel smooth and unobstructed.

[0021] like Figure 1-3 As shown, a discharging device for adjusting the quality of soybean tissue fibrous protein and expanding the production capacity, in this embodiment, includes a diverter device 4, a transition connection component 5, an extrusion cavity tube 6, a connecting rib plate 7, a mounting base 8 and a forming die 9;

[0022] The flow dividing device 4 is connected to the extrusion barrel 1 through the barrel end plate 3;

[0023] After the soy protein (hereinafter referred to as raw material) is adjusted to a certain moisture content, it is added into the extruder barrel from the feeding port of the extruder and moved forward under the push of the extrusion screw 2. As the material is subjected to high pressure, high heat and strong shear force in the machine cavity, the protein is denatured, and the protein molecules are arranged in a directional manner and become dense. There are multiple groups of mounting hole sizes on the barrel end plate 3, so it can be connected to the extruder barrel 1 of different models, which also ensures that the device can be adapted to different models;

[0024] The diverter device 4 includes a compression ring 41 and a diverter block 42. The compression ring 41 is provided with a conical surface, which is received at the tail end of the extruder barrel 1. It is used to collect the raw materials flowing out of the extrusion zone of the extruder barrel 1 to the center through the conical surface, and then distribute the raw materials to the corresponding extrusion cavity tube 6 through the diverter channel in the diverter block 42. The compression ring 41 has multiple models to choose from according to different taper angles, which are used to adjust the pressure and flow rate of the raw material at the spiral outlet. The diverter block 42 is configured with different models according to the number of diverter channels, and the specific designs include 2-hole diverter channels, 3-hole diverter channels, 4-hole diverter channels, etc.

[0025] The extrusion cavity tube 6 is provided with four identical groups, one end of which is connected to the flow dividing device 4 through the transition connection assembly 5, and the other end of which is connected to the forming die 9;

[0026] The transition connection assembly 5 includes an outer ring 51 and an inner plug 52. The outer ring 51 is connected to the diverter block 42 and is provided with a transition hole corresponding to the diverter channel. The inner plug 52 is installed in the transition hole for smoothly connecting the diverter channel and the extrusion cavity 6. The outer ring 51 is a part with a fixed size. The inner hole size of the inner plug 52 has multiple specifications, and its size is used to match the inner hole diameter of the extrusion cavity 6 with the inner hole diameter of the diverter device 4 to keep the raw material flow path smooth and unobstructed.

[0027] Each group of extrusion lumens 6 includes three sections of modular combined connected lumens units, and the inner diameter of the fluid channel of the combined extrusion lumens 6 gradually decreases from one end of the transition connection component 5 to one end of the forming die 9; at this time, since the fluid channel in the entire extrusion lumens 6 is designed to be gradual, when the raw material passes through this area, the fluid channel gradually becomes smaller, the extrusion is strengthened, the friction force is intensified, the force on the raw material protein is also large, the surface charge is redistributed and tends to be uniform, the molecular structure is further stretched and reorganized, the secondary bonds such as hydrogen bonds and disulfide bonds between molecules are partially broken, the protein is rearranged, and the degree of protein organization is strengthened;

[0028] Each lumen unit includes a lumen inner wall 61, a lumen interlayer 62 and a lumen outer sleeve 63. The lumen outer sleeve 63 is sleeved and connected to the outside of the lumen inner wall 61, and a lumen interlayer 62 for accommodating a temperature regulating fluid is formed between the lumen inner wall 61 and the lumen interlayer 62. The lumen interlayer 62 is connected to a mold temperature controller, which is used to regulate the temperature of the raw material in the lumen inner wall 61 by the temperature of the inserted temperature regulating fluid, and to steadily adjust the temperature of the raw material to keep the raw material stable in a very good organized state. The temperature of the extrusion lumen 6 can support the organization of soy protein within a certain range, and will reduce the organization of soy protein when it exceeds a certain temperature. When the extrusion temperature is 130°C, the raw material The solubility of the material is very low, and the water holding capacity and water retention capacity are very small. The product has a good degree of organization and a more obvious fibrous structure. The extrusion temperature is in the range of 150-180℃. The degree of organization increases with the increase of temperature. When the temperature is higher than 180℃, the organization begins to decrease. This is mainly because as the temperature increases, the material gradually becomes gelatinous, which is more conducive to protein denaturation. The protein is rearranged from the original disordered state to an orderly arrangement to form organized protein. However, as the temperature continues to rise, due to excess heat, the raw materials are easily "burned", which is not conducive to extrusion. Soy protein extrusion products need to have good thermal stability, so accurate temperature control is the most critical;

[0029] The connecting rib plate 7 is used to assist in the fixed connection of multiple groups of extrusion cavity tubes 6 to ensure the reliable mechanical rigidity of the assembly, and the forming die 9 is smoothly connected to the extrusion cavity tube 6 through the mounting base 8. The forming die 9 can be designed into different shapes according to product requirements, such as columnar, flat, etc. Each shape can be configured into different sizes according to product size requirements, such as columnar D12mm, D15mm; flat 5x35mm / 4x30mm, etc., wherein the flat forming die 9 gradually changes from a cylindrical shape to a flat outlet, and the inner surface of the gradient section is smooth and gentle. After the raw material passes through the forming die 9, a continuous strip product in an organized state is obtained, which is further processed into a columnar or sheet product that meets the requirements through the downstream equipment traction device 10 and the cutting device 11.

[0030] The working principle of the utility model is as follows: after the soy protein raw material is adjusted to a certain water content, it is added into the extruder barrel from the feeding port of the extruder, and moved forward under the push of the extrusion screw 2 until it moves to the diverter device 4. Then, it can be collected to the center through the conical surface in the compression ring 41, and then distributed to the corresponding extrusion cavity tube 6 through the diverter channel in the diverter block 42. In the extrusion cavity tube 6, since the fluid channel in the entire extrusion cavity tube 6 is designed to be a gradual change, when the raw material passes through this area, the fluid channel gradually becomes smaller, the extrusion is strengthened, the friction force is intensified, the raw material protein is subjected to a large force, the surface charge is redistributed and tends to be uniform, and the molecular structure is further stretched and reorganized. Secondary bonds such as hydrogen bonds and disulfide bonds between molecules are partially broken, proteins are rearranged, and the degree of protein organization is enhanced. The temperature of the extrusion cavity 6 can support the organization of soybean protein within a certain range. When the temperature exceeds a certain temperature, the organization of soybean protein will be reduced. Therefore, the cavity interlayer 62 is connected to the mold temperature controller, and the temperature of the raw material in the cavity inner wall 61 can be accurately controlled by the temperature of the inserted temperature regulating fluid. When the extrusion temperature is 130°C, the solubility of the raw material is very low, and the water holding capacity and water retention are very small. The degree of organization of the product is better, and there is a more obvious fibrous structure. When the extrusion temperature is in the range of 150-180°C, the degree of organization increases with the increase of temperature. When the temperature is higher than 180°C When the temperature rises, the organization begins to decrease. This is mainly because as the temperature rises, the material gradually becomes gel-like, which is more conducive to protein denaturation. The protein is rearranged from the original disordered state to an orderly arrangement to form organized protein. However, as the temperature continues to rise, due to excess heat, the raw materials are easily "burned", which is not conducive to extrusion. Soy protein extrusion products need to have good thermal stability, so precise temperature control is the most critical. After the raw materials pass through the last section of the cavity unit, they can be extruded through the correspondingly connected molding die 9, and the molding die 9 is smoothly connected to the extrusion cavity 6 through the mounting base 8, so it can promote the final more stable extrusion of the product, so as to obtain a more stable and controllable product output, and can effectively adjust the large The soybean organization degree can be improved, and the color, texture and nutritional characteristics of the product can be stabilized; and because the raw material discharge port is expanded from one to multiple, the production capacity can be doubled, thereby greatly improving the production efficiency of the equipment; at the same time, since the overall discharge device adopts a modular design, it can be adapted to different types of puffing extruders, making it more versatile, and it can also achieve the production of diversified products on one device, that is, one device can produce two or more soybean textured protein products of different sizes at the same time, so the combination effect is more flexible, that is, various configurations can be used in combination to quickly switch to produce soybean textured protein products of various shapes and sizes.
