This equipment and its associated production technology/process are designed for processing soap stocks derived from soybean, corn, peanut, cottonseed, and rapeseed oils. The aqueous phase (water) recovered from the process is neutral—with a pH value between 6 and 7—and is identical to the water originally present in the raw soap stock. The recovered oil has an acid value of approximately 30, features a yellow color, and offers a high oil yield. The production cost is only about 20 yuan per unit of output, and the process can be carried out using a simple heating tank
