Description
Technical field
The present invention relates to plant seed oil-producing technique, be specifically related to a kind of preposition milling process plant seed oil-producing technique.
Background technology
Prior art oil-producing technique much needs back-end processing to be because gained crude oil containing the substantial amounts of hydrotrope or hydrolysate,
The hydrotrope processes moisture and has also disposed water miscible nutritional labeling, such as vitamin simultaneously.Hydrolysate refers at squeezing high temperature
During heat seal reaction product or solvent product residual, such as toxin and benzopyrene.
Prior art milling process weak point also resides in the stir-fry needed by raw material and processs dehydration, and press chamber temperature is up to 170
DEG C-230 DEG C destroy alpha-linolenic acid contained by raw material things, simultaneously need to carry out water substitution in rear end to clean the water-soluble substances in crude oil
Reaching to purify purpose, do not reach being effectively retained of medicinal ingredient and edible nourishing composition, color and luster local flavor also changes simultaneously, contracting
The scope of little squeezing gained grouts recycling.
Prior art leaching refining method technique weak point also reside in rear end usually add solvent carry out deacidification dewaxing decolouring
Etc. a series of processing routines, the most also solvent residual, needs refine to eat, brings uncertainty and the wind of food safety
Danger.
Low temperature decortication disclosed in prior art Chinese patent " perilla oil production technology " (publication number CN105132126A)
Before squeezing perilla oil technique squeezing, plant seed moisture is more than 2%, and moisture causes at expressing process still more than 2%
Water-soluble substances and water-disintegrable material can be produced separate out, nutritious water-soluble substances can be caused in precipitation process to run off and can
The generation of water-disintegrable material that can be harmful.Raw material fat content immobilizes, and it is attached that the effect of decortication maximum is to reduce shell
Oils and fats, the impact for oil yield is very limited, and raw material secondary pollution probability but adds.
Summary of the invention
Needing stir-fry to process dehydration for solving prior art plant seed oil-producing technique raw material, gained crude oil is containing substantial amounts of water-soluble
