This machine has two stages, driven by independent transmission system. The first plodder is acting as a simplex refining to make soap pellets in the vacuum condition. In the final plodder, the soap is pressed and extruded out in billets through the orifice to feed the downstream cutter or stamper. All gears are precisely manufactured. The screws are made of high quality stainless steel, which have strong corrosion-resistance and are durable for long production. The front end of screw is designed with moving pore plate and fixing pore plate. It can be installed additionally by refining plate or net between them to enforce the martial refined ultimately in 0.02mm. The barrel inner body is made of high quality seamless stainless steel, without any leakage. The length and diameter rate of barrel and screw after enhancing length can reach 1:6, it extrude the material effectively and strength the compactness All other parts which are in contact with the soap are made of high quality stainless steel. Driving part adopts standard hard-teeth fine-ground gear face reducer with wear-resistance, low noise, compact structure which is quite stable and reliable. Specially designed and continuously improved water cooling system is especially suitable for the composite soap, transparent soap, and toilet soap The production capacity can be adjusted by the VFDs with the famous brand SANKEN. The special design for the reducer and the bearing box of the transmission system, avoid the problem of oil leakage from domestic similar gear box to the barrel and then pollute the soap, The screw wall is thick seamless steel tube, to ensure the long-term use and no water leakage, to avoid similar products using other materials barrel is easy to crack .The use of PLC control system, realize the whole line linkage. Secondary energy consumption energy-saving motors(national standards).
