Peanut peeling machine is composed of power device(electric motor, belt pulley, belt and bearing,etc), frame, feeding inlet, peeling roller(steel roller or sand roller), suction fan, etc. This machine is equipped with exhaust system and vibrating screen. As this equipment works, it rolls and transmits with friction at different speed. When the moisture of roasted peanuts is less than 5%(in case of burning), the best time for peeling is already. At such a time, exhaust system in peeler will suck red skins of peanuts away. The vibrating screen remove the peanut bud. As a result, peanut kernel is divided into two parts.
