Palm kernel oil machinery line/palmnut edible oil complete production line/automatic vegetable edible oil machine
oil seeds refined cooking oil
The whole palmnut edible oil complete production line contains three workshops:
1. pretreatment&expansion workshop
2 extraction workshop
3.crude oil refining workshop
Pretreatment&Expansion Workshop of palmnut edible oil complete production line Craft flow:
Crude seeds→ cleaning → softening → expanding → drying → to extraction workshop
Pretreatment and prepressing section is a very important section before extraction.It will directly affect extraction effect.
Oil Extraction Workshop of palmnut edible oil complete production line
Craft flow:
solvent steam
↓ ↓
extraction → mixed oil → evaporation→ steam-stripping → crude oil
Extractor types:
Level rotation extractor, loop type extractor, chain extractor
Extraction methods:
Use organic solvent through soaking or spraying contact methods to extract oil from oilseeds.
Advantages of extraction craft:
1.High oil yield, low residual oil in meal;
2.Low labor intensity;
3.Good working environment;
4.Good meal quality.
Negative pressure evaporation helps to improve crude oil quality.
Oil Refining Workshop of palmnut edible oil complete production line
Craft flow:
crude oil → degumming&dephosphorization → deacidification → drying → decolorization → deodorization → defatting → dewaxing → finished oil.
Refining methods:
oil refining is according to the different usage and requirements, utilizing the physical methods and chemical processes to get rid of the harmful impurities and needless substance in the crude oil, getting standard oil.
Advantages of refining craft:
1. After refining the impurity of oil must be less than 0.2% ;
2.Recycling system save power and money;
3.Lower oil waste.
