Brief introduction for the equipment:
Refining pot: also named Dephosphorization and deacidification tank, under 60-70¡æ, it occurs acid-base neutralization reaction with sodium hydroxide. After stirring by reduction box, it can decrease the acid value in oil and separate the impurity, phospholipid which will enter into soap stock. The oil can be refined further.
Bleaching pot (decoloring pot): Also named bleaching and dewatering pot, it removes water from oil by vacuum. The bleaching earth is breathed into bleaching pot, after stirring, filtrated by filter and change the color of the oil.
Vertical blade filter machine: Equipped with vertical leaf filter to remove used bentonite from the oil, operating conveniently and continuously, low laboring tense, keeps environment well, keeps oil residence in deposable bleaching earth in low level.
Deodorization pot£ºIt uses USU 304 stainless steel plate, under the vacuum condition of vacuum and high temperature (220-240¡æ). The deodorization system can remove fatty acid and other rare delicacy high efficiently. Meanwhile, the pot has the advantage of lowering steam consuming and avoid of the hydrolyzation of oil;
Process characteristics of 5T/D rice bran oil refining equipment:
1) Both short mixed and long mixed process are adapted in washing sector, which ensures washing effectiveness£»
2)Equipped with vertical leaf filter to remove used bentonite from the oil, operating conveniently and continuously, low laboring tense, keeps environment well, keeps oil residence in deposable bleaching earth in low level
3)Due to accurate stirring method, decreased the maximum distance between the oil of cooling facet so as to ensure the same temperature of crystal with same quality. Better guaranteed that in the process of crystallization, crystal will not cluster in an intense area.
4)Flexible system, cooling curve can be easily altered by changing water temperature, thus the kinds of products can be changed easily.
5)Stabilization of product quality
