This is advanced equipment for pig dehairing on the market. The interior of this machine consists of U-type boards to avoid damaging or breaking the carcass. It allows pigs of different sizes to enter due to its wide space. The process can be controlled by machine systems, and two rollers driven by two reduction motors can remove hair quickly. This equipment is suitable for slaughterhouses with pig processing output. (Remark: Pigs shall be scalded before dehairing and kept for 3 minutes in water or steam at 60-65 degrees centigrade.)
