AI Technical Summary
In existing vegetarian meat molding machines, the single fixed-distance structure of the thread leads to the consistent direction of the fibers of the protein powder, and the taste of the vegetarian meat products is average, making it difficult to achieve fiber interlacing to improve the texture.
A vegetarian meat processing and forming screw is designed. The screw includes a variable diameter extrusion section and a mixed molding section. The threads of the variable diameter extrusion section are double-threaded structures. The mixed molding section is divided into multiple threads, and each thread is spaced a distance. Through this structure, the fiber interlacing of the protein powder material is achieved.
The protein powder is changed from fluffy extruded to compact through the variable diameter thread part, improving the puffing efficiency; the multi-stage extruded thread structure makes the fibers flip and stacked, increasing the strength and toughness of the puffed vegetarian meat, simulating the taste of the material of the vegetarian meat.
