The pickling machine (rolling and kneading machine) allows the meat to be pressed under positive pressure at a fixed time and expand under negative pressure at a fixed time, playing a frictional role without damaging the skin. By using the principle of a mechanical drum, the cured meat is rubbed against each other, accelerating the speed of seasoning infiltration into the meat and greatly reducing the pickling time. Made of all stainless steel, reasonable and reliable.
