With the continuous improvement of living standard of people, the supply and demand of meat products in China are seriously unbalanced. By 2030, the supply gap of meat products in China can reach 3804 ten thousand tons, and the food safety in China is seriously threatened. In order to alleviate the pressure on the effective supply of meat-based agricultural products, protein meat production technologies including plant protein-based plant protein meat and novel cell factory-based animal culture meat have been gradually developed in recent years. Compared with traditional agriculture and livestock raising, the novel protein meat product has remarkable advantages, not only can solve the problems of hormone, antibiotics and pesticide residues in traditional agriculture and the infection of viruses, parasites and pathogenic bacteria caused by zoonosis, but also can save 75% of water and reduce 87% of greenhouse gas emission and 95% of land area requirement.

The bean product is a food which is daily liked by Chinese people, besides bean curd, bean curd skin and dried bean curd which are processed and manufactured by the traditional process, the puffed bean product is popular with people, wherein the protein meat has soybean nutrition and meat taste, so that the protein meat has representativeness. The protein meat is named as tissue protein, and is a bean product formed by mixing and stirring cold-pressed bean flour, low-temperature bean pulp, wheat starch and isolated soybean protein uniformly, extruding the mixture from a die opening through screw extrusion and heating. The existing protein meat processing equipment generally adopts a single-screw structure form. The food extruding device is structurally characterized in that a main body of the food extruding device is a sleeve and an extruding screw rod, the extruding screw rod is located inside the sleeve, a feeding port is designed at one end of the sleeve, and a food extruding end is arranged at the other end of the sleeve. The equipment has shorter screw, smaller shearing force to materials and insufficient product expansion degree; the existing machine adopts an external heating mode, a heating element is fixed outside a screw rod sleeve, and materials are insufficiently heated in the screw rod sleeve, so that the final product is low in fiberization degree, insufficient in strength and poor in taste.

Generally, although commercial protein meat products are on the market, at the initial stage of the current research, a plurality of technical bottlenecks are still to be broken through, and the organoleptic properties and the nutritional value of the protein meat are to be improved. Therefore, a production device for producing protein meat, which is more efficient, reliable and safe, is urgently needed in the market.
