2-300T/Day Seed Oil Refining Machine

Oil Refining Machine process can remove phospholipid, FFA, pigment, off-flavor and other impurities. It includes the following sections: Oil Dugumming, Oil Deacidifying, Oil Bleaching, Oil Deodorizing and Oil Dewaxing.

Oil Bleaching:High-activity clay is added into oil, mix and heat mixture of oil and clay to make the small particle of pigment absorbed on the crystal of clay. this machine is of perfect mechanism, liable performanceand is well configured equipment.

Oil Deodorizing:The heat of most bleached oil is recovered by heat exchangers, the bleached oil is heated to the process temperature by mineral oil or high pressure steam and then the oil enters into the combined deodorizer, the deodorizer is a combined type: the upper is packing structure, which is used to remove odor components like FFA, the lower is plate type used for heat bleaching and making product quality more consistent. Oil coming from the deodorizer is cooled and stored after series of heat exchange, volatile like FFA is collected and stored as by products.

Oil Dewaxing:It can improve oil palatability, so it plays an important role in the quality of finished oil. At the same time, dewaxing can improve oil transparency and brightness. At present, winterizing method is very popular to dewaxing.

It has the following features:
1. Less oil loss and high oil refining ratio;
2. No waste water in process of production;
3. More FFA is distilled out;
4. More suitable for oil with high acid value and low gum-impurity.

Chemical Refining: Chemical Refining means removing FFA in a way (acid-base neutralization). Gum and soapfoot is separated by centrifuges. Chemical refining has following features:
1. Fine Adaptability and less requirement of crude oil quality;
2. Consistent product oil is got;
3. Less clay is added into compared with physical refining.
