The vacuum refrigerated tumbler operates under vacuum conditions. Based on the principle of physical impact, it allows the meat to tumble up and down and collide inside the drum, enabling the materials to evenly absorb the pickling solution and enhancing the elasticity of the meat. The whole machine is made of high - quality stainless steel with a reasonable structure. The two ends of the drum adopt a pressure - applied sealing cap structure, which enlarges the internal space of the drum and ensures a uniform tumbling effect. This machine produces low noise and has stable performance.
