Description

Technical Field

[0001] The invention relates to the technical field of drawing protein preparation, in particular to a method for preparing high-chewy drawing protein. Background Art

[0002] As a nutritious and environmentally friendly alternative, plant-based protein food has attracted widespread attention due to its advantages such as high protein, low fat and no cholesterol. Among them, fibrous protein, as an important representative of plant-based protein food, has shown great application potential in vegetarian products, imitation meat products and healthy snacks due to its unique fibrous structure and meat-like taste.

[0003] Traditional methods for preparing fibrous protein often find it difficult to simultaneously meet the requirements of high hardness, elasticity and excellent chewiness, resulting in a product that is difficult to compare in taste with real meat. In order to prepare fibrous protein products with high chewiness and excellent texture characteristics, it is necessary to comprehensively consider the use of additives, the optimization of extrusion process parameters and the adjustment of raw material ratios. The preparation of fibrous protein also requires a series of processing techniques, including mixing and stirring raw materials such as soy protein, wheat protein and low-temperature edible soybean meal. When existing mixing and stirring equipment stirs these raw materials, it is difficult to quickly process the raw materials that are clumped together only through the stirring structure. Long-term stirring is prone to protein denaturation. In addition, there are some larger particles in raw materials such as low-temperature edible soybean meal that have not been crushed. Direct stirring is also difficult to ensure the mixing uniformity of the raw materials, which reduces the preparation efficiency of high-chewy fibrous protein. Summary of the invention

[0042] Working principle: When preparing high-chewy fibrous protein, soybean protein, wheat protein, low-temperature edible soybean meal, water, L-cysteine ​​and calcium chloride are mixed, and these raw materials are sent into the barrel 1 of the mixing and stirring equipment, and the motor 15 and the motor 214 are started. The motor 15 controls the gear 16 and the meshing gear 217 to rotate, and the motor 214 controls the gear 422 and the meshing gear 523 to rotate in the opposite direction. When the gear 16 and the gear 217 rotate, they will drive the vertical pipe 18 and the vertical pipe 29 fixed at the bottom to rotate, and the gear 42 2 and gear five 23 rotate in opposite directions, and the rotating roller 24 fixed at the top of gear four 22 and gear five 23 drives the spiral blade 25 to rotate on the inner wall of standpipe one 8 and standpipe two 9, so as to transport the mixed raw materials. The mixed raw materials are transported from the bottom to the top inside standpipe one 8, and from the top to the bottom inside standpipe two 9. Circular arrays of filter holes one 20 are provided at the top and bottom of standpipe one 8 and standpipe two 9. The larger raw materials will be filtered and stay on the outer wall of the filter hole one 20 at the bottom of standpipe one 8 and standpipe two 9. The second pipe 9 rotates itself, and the filtered and retained raw materials rotate with it. A bracket 11 and an arc plate 12 are arranged at the top and bottom of the cylinder 1. The arc plate 12 is provided with staggered blades 1 31 and blades 2 33. The vertical pipe 1 8 and the vertical pipe 2 9 rotate to carry the filtered large-sized raw materials together with the arc plate 12 at the bottom of the cylinder 1. The large-sized raw materials are crushed by the staggered blades 1 31 and blades 2 33, and a brush 32 is arranged between the blades 1 31 and blades 2 33 on the arc plate 12 to clean the raw materials blocked in the filter hole 20. After cleaning, the motor 15 controls the gear 16 and the gear 2 17 to rotate in the opposite direction after rotating for a certain period of time. The motor 2 14 also controls the gear 4 22 and the gear 5 23 to rotate in the opposite direction. The rotation direction of the spiral blade 25, the vertical pipe 1 8 and the vertical pipe 2 9 is reversed. The mixed raw materials are transported from the top to the bottom inside the vertical pipe 1 8, and from the bottom to the top inside the vertical pipe 2 9. The large-sized raw materials are filtered by the filter hole 1 20 at the top of the vertical pipe 1 8 and the vertical pipe 2 9, and then crushed by the arc plate 12 at the top of the cylinder 1 in cooperation with the blade 1 31 and the blade 2 33.

[0043] When the riser 1 8 and the riser 2 9 rotate, the gear 3 21 cooperates with the rack 27 to drive the annular frame 10 to rotate. The rotation speed of the annular frame 10 is slower than that of the riser 1 8 and the riser 2 9. The four rolling plates 13 connected to the rotating shaft 30 at the four corners of the outer wall of the annular frame 10 also rotate accordingly. When the annular frame 10 rotates counterclockwise, the rolling plates 13 rotate under the action of the rotating shaft 30 and abut against the limit block 29. At this time, there is a certain distance between the annular frame 10 and the inner wall of the cylinder 1. When the rolling plates 13 stir the mixed raw materials, the filter holes 26 on the outer wall of the rolling plates 13 filter the mixed raw materials. The material slides along the inclined outer wall of the rolling plate 13. When the large-sized raw materials move to the rolling plate 13 and the inner wall of the cylinder 1, they are crushed and processed by the rolling plate 13. The mixed raw materials on the inner wall of the cylinder 1 can be continuously filtered and crushed by stirring. When the annular frame 10 rotates clockwise, the rolling plate 13 rotates with the rotating shaft 30 and abuts against the limit block 28. At this time, there is no gap between the rolling plate 13 and the cylinder 1, and it is slidably connected to the inner wall of the cylinder 1. When the annular frame 10 rotates, the mixed raw materials crushed on the inner wall of the cylinder 1 can be cleaned, including the mixed raw materials that have just been crushed and adhered to the inner wall of the cylinder 1.

[0044] Stirring blades 18 and 19 are arranged on the outer walls of the riser 1 8 and the riser 2 9, which rotate in opposite directions all the time, so as to better stir the mixed raw materials. When the two gears 2 17 rotate, the top, the movable rod 4 and the pressing block 6 are driven to rotate. A feeding rack 2 is arranged on the inner wall of the mounting hole at the top of the cylinder 1. Additives are put into the cylinder 1 through the feeding pipe 3 at the top of the feeding rack 2, and a corresponding amount of additives is put into the feeding pipe 3. Each time the movable rod 4 rotates one circle, the pressing block 6 presses the pressure block 7 on the feeding rack 2. When the pressing block 6 leaves and separates from the pressure block 7, the feeding rack 2 is reset under the action of the spring 34. The feeding rack 2 slides left and right continuously, and the additives in the feeding pipe 3 are more easily diffused when entering the cylinder 1, and are more fully and quickly contacted and mixed with the mixed raw materials being stirred and rotated inside. The additives scattered by sliding left and right can also further prevent the possibility of sticking together.

[0045] The technical means disclosed in the solution of the present invention are not limited to the technical means disclosed in the above technical means, but also include technical solutions composed of equivalent replacement of the above technical features. Matters not covered in the present invention belong to the common knowledge of those skilled in the art.
