1. Continuous alkali refining shortens contact time between oil and lye,reduces grease saponification, lowers refining consumption, and improves efficiency.
2. Decolorization adopts technology of combining premixing and steam mixing bleaching,which improves bleaching efficiency, saves consumption of bleaching clay, and it is simple and convenient to operate; and negative pressure state avoids oxygen in the air from contacting with hot oil, thereby ensuring oil product quality, inhibiting acid value to rise again, and lowering peroxide value.
3. Deodorization adopts new type continuous deodorization equipment which is applicable for deacidification and deodorization of plant oil with high acid value and low-resin content, the actual production proves its most obvious advantages are strong deacidification ability, excellent hot bleaching effect, high refining rate (increase for 0.4/AV), good oil quality and so on.
4. The process has multiple heat exchange, which makes full use of the heat energy system, effectively reduces steam consumption, and also has the advantages of adjustable production process, flexible operation, high automatic degree, environment sanitation and so on.
