As the production of sunflower seeds in China develops, it will improve the supply of edible oil for people. Currently, the quality of sunflower seeds oil produced in our province is generally considered to have the shortage of strong smoke, rapid evaporation, high content of natural sediments and lack of clarity. Compared to soybean oil, its price is high, so it is unpopular in market. To improve the market acceptance of sunflower oil, in addition to promoting its nutritional valve, it is crucial to enhance the quality management of the product. Experience shows that the main factor affecting oil quality is the refining process, thus, this refining equipment can solve this problem.

Operational Process of Edible Oil Refining Equipment:

Crude oil is pumped into the refining pot for de-gumming and neutralization. When the oil and soap are clearly separated and rapidly sink, stop stirring, allow to settle, and then pump the upper clear oil to the water washing pot. The soap foot is drained from the bottom to the soap foot container, and when it contains more oil, stop draining and pump the soap foot into the soap foot container. The remaining oil in the refining pot is mixed into the next pot for continued processing.

The clear oil transferred from the refining pot is washed and then sent to the de-coloring pot for adsorption de-coloring. The de-colored oil is pumped to the plate filter for filtration and then to the polishing filter for further filtration. After cooling in the cooler, it enters the de-colored clear oil tank. The de-colored clear oil is sucked from the tank into the de-odorizing pot for de-odorizing under a residual pressure of 3-5 torr. The de-odorized oil is placed in the heat exchanger tank, and after being emptied, the next batch of de-colored clear oil is sucked through the heat exchanger into the de-odorizing pot, entering the next round of de-odorizing. The de-odorized oil in the heat exchanger tank is cooled with cold water, pumped out for polishing filtration, and then enters the finished oil tank.
