This machine has one stage and is used for soap mixing and refining. It’s driven by integrated motor and  gear box, higher driving efficiency, and with specially designed sealing, it can avoid the oil leakage from the gearbox into the screw chamber to cause soap contamination. The lengthened screw chamber design can reach 1:6 for the screw diameter vs effective barrel length, which can extrude the material effectively and increase the compactness. The barrel inner body is made of high quality seamless stainless steel, without any water leakage. The refining plate or net can be installed on the first plodder front part to enforce the martial refining effects to optimization. Specially designed and continuously improved water cooling system and the different screw inner diameter and pitch design are especially suitable for the laundry soap and toilet soap. Except the aluminum screws, all parts contacting with soap are made of high quality stainless steel.
