Description
Technical field
A kind of method that vegetable oil precipitates after being squeezed the present invention relates to removing machine, belongs to vegetable fat processing technique field.
Background technology
In recent years, in edible oil field, more and more consumers have solely the edible oil feelings using cold pressing process production
Clock.Count reason accurately, when process safety, using low-temperature cold pressing squeezing process, without high temperature refinery；Second is that features good taste, cooking mouth
Feel pure, aromatic flavour；Third, it is full of nutrition, vegetable oil naturally effective active constituent is remained to the maximum extent.
However, crude vegetal generally all contains wax and certain colloidal substances, they are easy crystallization analysis during storage
Go out, grease is made to become cloudy and influence exterior quality.In order to keep grease clear at low temperatures and reach salad oil
Quality standard, at this stage remove precipitation of grease mainly have two kinds of winterization and aquation degumming.Winterization method is simple, to a certain degree
On can remove precipitation of grease, but removal effect is limited, and one to after two months, and grease can generate precipitation or occur muddy again
Turbid phenomenon, and the winterization time is relatively long, influences production efficiency；Although and aquation degumming effect is relatively preferable, can draw
It plays vegetable fat gas flavour obviously to change, and trichloropropanol ester in grease is made to increase, can also destroy certain natural in grease
Active constituent.
