Abstract

The present invention is that a kind of food oils leach production technique.It replaces No. 6 industrial solvents that use at present with liquefied petroleum gas (LPG) etc. as leaching solvent, under normal temperature and certain pressure condition, leach the grease in the oil plants such as soybean, peanut, Semen Brassicae campestris, and make solvent evaporation with the method that reduces pressure at normal temperatures, soaked material with quilt and separated, reach and under the situation of not destroying plant protein in the oil plant, extract greasy purpose with extract.

Description

The invention belongs to foodstuffs industry grease production specialty, is the process system that a kind of extraction process extracts food oils.

The pre-method of pressing, leach the extraction of two steps of the general employing of the production of food oils is at present extracted the grease in the oil plants such as soybean, peanut, Semen Brassicae campestris.Leaching is to adopt No. 6 industrial solvent extraction pre-pressed cakes to put forward oily processing method, and the major ingredient of No. 6 solvents is a normal hexane.Processing method is: at first leach pre-pressed cake with No. 6 solvents in leacher, cake after will leaching then (specialty claims the dregs of rice) is delivered to evapo-separated machine, steam wherein solvent through evapo-separated machine high temperature, the dregs of rice are discharged this operation, and the solvent that steams recycles through condensation, after anhydrating.Leach the leach liquor of forming by No. 6 solvents and food oils (specialty title mixing oil) of gained, through evaporator evaporation go out wherein solvent and must crude oil, solvent vapour recycles after condensation.This technology has been widely used in oil prodution industry, and its main drawback is that protein is destroyed after the steaming of evapo-separated machine high temperature is taken off in the dregs of rice, can't utilize.

The objective of the invention is in the grease leaching process to steam and slough, protein is not damaged, provide condition for effectively utilizing vegetable-protein except that the solvent in the dregs of rice without high temperature.

Accompanying drawing is a process flow sheet of the present invention.Among the figure: the 1st, holding tank, the 2nd, lift, the 3rd, charging bin gate, the 4th, pressure loading valve, the 5th, leacher, the 6th, go out dregs of rice bin gate, the 7th, dregs of rice transfer roller, the 8th, mix oil pump, the 9th, well heater, the 10th, the evaporation valve, the 11st, miscella tank, the 12nd, compressor, the 13rd, condenser, the 14th, solvent non-conservation tank, the 15th, solvent delivery pump.Use in the technology and removed boiling point under diolefine and the normal pressure and be higher than the liquefied petroleum gas (LPG) of component of zero centigrade or leuna gas, liquefied propylene, liquefied butane, liquefaction Trimethylmethane, liquefaction butylene as leaching solvent.

Holding tank 1 lower part outlet is connected with lift 2 inlets, lift 2 outlets are connected with charging bin gate 3, charging bin gate 3 is installed on the opening for feed of leacher 5, under leacher 5 distiller grains outlets dregs of rice bin gate 6 is housed out, going out dregs of rice bin gate 6 bottoms is connected with dregs of rice transfer roller 7, pressure loading valve 4 is equipped with on leacher 5 tops, pressure loading valve 4 is connected by the inlet mouth of pipeline with compressor 12, leacher 5 tops link to each other with 15 outlets of solvent delivery pump through piping, leacher 5 bottoms link to each other with 8 imports of mixing oil pump through pipeline, mixing oil pump 8 outlets links to each other with miscella tank 11 through pipeline, miscella tank 11 tops connect well heater 9 imports through evaporation valve 10, and well heater 9 outlets connect leacher 5 bottoms, and compressor 12 outlets connect condenser 13 imports, condenser 13 outlets connect solvent non-conservation tank 14, and solvent non-conservation tank 14 bottoms connect 15 imports of solvent delivery pump.

During the operation of this process system, after squeeze cake, pre-pressed cake or the oil plant material embryo that need once leach are kept in holding tank 1, enter in the leacher 5 through lift 2, charging bin gate 3, treat to close after leacher is filled charging bin gate 3, pressure loading valve 4 and go out dregs of rice bin gate 6, will leach solvent by solvent delivery pump 15 and squeeze in the leacher 5.After leaching process is finished in leacher inside, squeeze into miscella tank 11 through mixing oil pump 8 by the mixing oil that leaching solvent and vegetables oil are formed.Open pressure loading valve 4, evaporation valve 10 then, the solvent in the mixing oil of 11 li of miscella tanks is evaporated because of decompression, and continuous additional heat in miscella tank 11, do not descend to keep its temperature.The solvent vapour that evaporates in the miscella tank 11 enters leacher 5 after being heated by well heater 9, makes the leacher temperature maintenance more than zero centigrade, and solvent evaporates because of decompression in the dregs of rice that leacher is 5 li.Solvent vapour enters the inlet mouth of compressor 12 through pressure loading valve 4, by compressor 12 compressions, condenser 13 condensation liquefactions.Solvent after the liquefaction flows into solvent non-conservation tank 14 and recycles.After treating that solvent evaporation in the dregs of rice of 5 li of leachers is intact, the dregs of rice enter dregs of rice transfer roller 7 by going out dregs of rice bin gate 6, send this operation.After solvent evaporation in the mixing oil that miscella tank is 11 li was intact, the remaining hair vegetables oil that leaches was discharged this operation through lower part outlet.

Compare with the extract technology of present use, the present invention uses under the normal temperature and pressure and to make solvent as the liquefied petroleum gas (LPG) of gas etc. to replace boiling range be No. 6 solvents of 60 degree Celsius to 90 degree, under normal temperature and certain pressure, leach oil plant, and make the method for solvent gasification remove in the dregs of rice with decompression at normal temperatures and mixing oil in solvent.Avoided in the dregs of rice protein destroyed, for the vegetable-protein utilization provides precondition because of heating removes solvent.

Realize that when of the present invention, leacher can adopt flat rotary extractor, the board-like leacher of fixed railing or pot group type leacher.Pressure loading valve 4, evaporation valve 10 and go out dregs of rice bin gate 6 and preferably adopt electronic or Pneumatic method control, total system adopts control automatically, miscellaneous equipment general-purpose equipment.
