Abstract
The invention discloses a kind of regenerated techniques of oil foot.Present invention process is simple, easily operated.1, it dilutes: can be carried out at once after oil refining, oil foot temperature is 55~65 DEG C at this time, is not required to preheat.Directly by 300kg, 90 DEG C of hot water is added in 1000kg oil foot, starts blender and be stirred for uniformly；2,3.5kg citric acid is previously dissolved in 100kg, in 90 DEG C of hot water, added in oil foot, is stirred for uniformly；3,150kg salt is slowly added in oil foot, is stirred continuously in the process, and heated, finally maintain oil foot temperature at 95 DEG C or so, until oil foot is no longer sticky；4, above-mentioned oil foot 15 hours are stood, isolates upper layer edible vegetable oil.
Description
Technical field
Extracting edible oil technique that the present invention relates to one kind from oil foot.
Background technique
Remaining oil foot is all passed into disuse after general edible oil factory extracting edible oil (cotton oil, rape oil, soya-bean oil etc.) at present,
Or it uses it for anything else.Still contain a certain amount of edible oil in oil foot, discard or use it for anything else, this results in a kind of greatly wastes, also drop
Low oil productivity.
Summary of the invention
The object of the invention is to save material, improve oil productivity to solve above-mentioned phenomenon.
In order to achieve the above objectives, the present invention uses following process flow:
1, it dilutes: oil foot is preheated to 55~65 DEG C in oil cauldron, 90~100 DEG C of the 25~35% of oil foot weight are added
Hot water is diluted, and starts blender, is stirred evenly；
2, it is acidified: the 3 of oil foot weight~5 ‰ citric acid is previously dissolved in 90~100 DEG C of the 5~15% of oil foot weight
In hot water, adds in oil foot and be stirred for uniformly；
3, it saltouts: 10~20% salt of oil foot weight being slowly added in oil foot, is stirred continuously, heats in the process, and tie up
Oil foot temperature is held between 90~100 DEG C, until oil foot is no longer sticky；
4, stratification: stand oil foot 12 hours or more, isolate upper layer edible vegetable oil.
The positive effect of the present invention is:
1, using oil foot as raw material, raw material are saved；
2, oil productivity is improved；
3, present invention process is simple, easily operated.
The present invention is described in detail below with reference to embodiment:
1, it dilutes: can be carried out at once after oil refining, oil foot temperature is 55~65 DEG C at this time, is not required to preheat.Directly will
300kg, 90 DEG C of hot water are added in 1000kg oil foot, start blender and be stirred for uniformly；
2,3.5kg citric acid is previously dissolved in 100kg, in 90 DEG C of hot water, added in oil foot, is stirred for uniformly；
3,150kg salt is slowly added in oil foot, is stirred continuously in the process, and heated, finally maintain oil foot temperature at 95 DEG C
Left and right, until oil foot is no longer sticky；
4, above-mentioned oil foot 15 hours are stood, isolates upper layer edible vegetable oil.
Claims (1)
1. a kind of regenerated technique of oil foot, it is characterised in that the technique is the following steps are included: A, dilution: by oil foot in oil cauldron
55~65 DEG C are preheated to, 25~35% 90~100 DEG C of hot water of oil foot weight is added, is diluted, and start stirring
Device is stirred evenly；B, it is acidified: the 3 of oil foot weight~5 ‰ citric acid is previously dissolved in the 90 of the 5~15% of oil foot weight
In~100 DEG C of hot water, adds in oil foot and be stirred for uniformly；C, it saltouts: 10~20% salt of oil foot weight is delayed
It is slow to be added in oil foot, it is stirred continuously, heats in the process, and maintain oil foot temperature between 90~100 DEG C, until oil foot is no longer
Until sticky；D, stratification: stand oil foot 12 hours or more, isolate upper layer edible vegetable oil.
