Description
Technical field
The utility model relates to a kind of production system of extraction process depickling Rice pollard oil.
Background technology
Rice pollard oil is the grease that utilizes paddy processing gained sub product rice bran to produce; 200,000,000 tons of China's paddy annual outputs; 2,000 ten thousand tons in processing gained sub product rice bran can be produced 3,000,000 tons of Rice pollard oils, is widely used in eating, fields such as medicine, chemical industry, foodstuff additive.Mainly contain oleic acid and linolic acid in the edible rice bran oil, also contain thiaminogen, the acid of paddy steroid and vitamin E, the ability reducing cholesterol is prevented and treated cardiovascular disorder, and the treatment nervous system disorders is a kind of nutrient health care edible oil.
Paddy adds man-hour, and rice bran leaves parent paddy and contacts with oxygen, under the effect of lipolytic enzyme; The free fatty acid content of rice bran crude oil rises rapidly; Rice bran crude oil free fatty acid content is 10%～15%, even some is up to 15%～30%, has a strong impact on oil quality and refining yield.
The method of Rice pollard oil depickling at present mainly contains alkali-refining deacidification method, distillation depickling method, esterification deacidification method.The alkali-refining deacidification method is applicable to the Rice pollard oil of free fatty acids low levels, and the Rice pollard oil higher to free fatty acid content needs repeatedly alkali refining, consumes a large amount of alkali lye, and cost increases, and produces great amount of wastewater; The product refining yield is low, and thiaminogen runs off big, and color and luster is dark.Distillation depickling method is strict to the grease pre-treatment, and the higher Rice pollard oil of free fatty acid content needs repeatedly the HTHP distillation, consumes great amount of heat energy, electric energy, and production cost is high, and vitamin E is lost in the free fatty acids; And grease is at high temperature, can produce the material that is harmful to health, the trans fatty acid of generation and propylene chlorohydrin, and edible back suppresses to grow.The esterification deacidification method is to utilize the enzyme catalyst esterification to add glycerol method to reduce grease, but this method esterification temperature is high, add catalyzer after; Can produce a sweet fat, sweet two fat, grease oil has the sex change phenomenon, the unsuitable edible oil of doing; Simultaneously can't carry out scale prodn; And use enzyme to cost an arm and a leg, production cost is high, is not suitable for suitability for industrialized production.
Summary of the invention
The technical problem that the utility model will solve provides a kind of production system of extraction process depickling Rice pollard oil, and this system operation simply, does not need high temperature heat source.
The technical solution of the utility model is:
A kind of production system of extraction process depickling Rice pollard oil; Its special character is: comprise the cylinder centrifugal extractor; Described cylinder centrifugal extractor is respectively equipped with oil inlet, ethanol import, outlet I and outlet II, the depickling oil tank that is connected with the outlet I, the lipid acid and the ethanol mixing storage tank that are connected with the outlet II; With lipid acid and ethanol mixing storage tank vaporizer through pipe connection; Be provided with the pump I on the pipeline between lipid acid and ethanol mixing storage tank and the vaporizer, the free fatty acids storage tank that is connected with vaporizer tower bottom outlet, the condensing surface that is connected with the vaporizer tower top outlet; The ethanol withdrawing can that is connected with condensing surface, described ethanol withdrawing can outlet links to each other with the ethanol import of cylinder centrifugal extractor and forms the closed cycle pipeline.
Said cylinder centrifugal extractor adopts at least three monomer extractors to be in series, and the outlet II of back one-level is that ethanol outlet and enter the mouth with the ethanol of previous stage is connected, and reaches continuous production, satisfies the requirement of output and quality.
Said cylinder centrifugal extractor is that three monomer extractors are in series.
Its advantage of the utility model is:
(1) operation of equipment is simple, and process cost is low.
(2) do not need high temperature heat source, save energy has huge economic and social benefit.
(3) whole extraction, reclaimer operation form the closed cycle pipeline, operating process is continuous, can large-scale production.
