Principle of vacuum rolling and kneading machine: allowing meat chunks or fillings to flip up and down in the drum, collide and hit each other, thus achieving the pickling effect. The pickling solution is fully absorbed by the meat, enhancing its adhesion and elasticity, and improving the taste and cross-sectional effect of the product; Can enhance water retention and increase yield; It can improve the internal structure of the product. The vacuum rolling machine also has the functions of computer control and frequency conversion technology. The update has added a remote control operating system, making the machine more convenient and energy-efficient to use.
