Abstract

Use: oil and fat industry. SUMMARY OF THE INVENTION: Seeds or pre-press cake are extracted at a water ratio of 1: 2 with a hank of water-in-oil emulsion containing a mixture of water, polyester glycol ester of copestock fatty acids and gasoline or hexane, with a ratio of polyethylene glycol ester of copesstic fatty acids and gasin or hexane from 0.2 : 95 to 0.5: 90 ppm, and water from 4.5 to 5 ppm, for seeds and from 5 to 10 pph. for forpressovrgo cake. The phases are extruded by pressing.

Description

FIELD OF THE INVENTION The invention relates to the miscellaneous industry and concerns methods for extracting vegetable oils.

Closest to the proposed method is a method where the crushed oil-containing seeds are moistened with a mixture of water, polyethylene glycol ester of soapstock fatty acids as surfactants and gasoline sludge and hexane as a solvent at a ratio of water: surfactant: solvent of 29.8: 0.2: 70 to 14: 1: 85, the obtained miscella is separated from the moistened mint, the mcc is extracted with gasoline or hexane in opposite-repeated multiple consecutive passes through the forming dies with simultaneous pressing. Horno separated miscella otgyn and dissolved solvent from the miscella. In the processing of the mtc in the first stage with a mixture of water, coagg polyethylene glycol ether waste fatty acids and gasoline or hexane, which is an emulsion

such as water in oil, the moistening of the gel part of the weave, the easily refined part of high-quality oil is moistened, the oil with the minimum content of concomitant substances in non-polar solvent. a easily deformable mold for further extraction. ir The disadvantages of the method include the complexity of the process, since it uses repeated pressing of solid material that requires cumbersome structural design. Another disadvantage of this method is the high consumption of solvent, which leads to a decrease in the concentration gradient of miscella and an increase in the irretrievable loss of a valuable component — in the extragamma.

The aim of the invention is to increase the oil yield, improve the quality of the meal and intensify the process.

To this end, a method for producing a vegetable oil, comprising extracting oil.

The reduction of crushed material containing an emulsion of water-in-oil type containing a mixture of water, polystilenglycolic ester of co-effluent fatty acids and gasoline or hexanes, and separation of the phases by pressing, is characterized in that in order to increase the yield of oil, improve the quality and intensify the process, as an extractable materials are used by these thu-thu or forprereisovy cake, the ratio of polyethylglycolic ester of co-acidic acids and gasoline or hexane I take 0.2 st S5 to 0.5: 90 mh, and the amount of water is 4.5 to 5 m .H. for raw pulp and from 5 to 10 m.ph. for the pre-press cake within the hydromodule from 1: 1 to 1: 2, while the ostroscia is carried out by the flow.

The invention has the following significant difference from the prototype.

The method makes it possible to carry out the extraction of mcc only in the backflow, which is achieved by treating an emulsion of the type (V / M), where the content of the ooda is 4.5–5%.

The method eliminates multiple pressing, as a result of which the economic costs of the extraction process are reduced: the bulkiness and metal consumption of the equipment is reduced, the consumption of heat-transfer agent is saved, the installation is simplified.

In the method, the solids content after extraction does not exceed 14-15%, and as a result, the quality of the meal is improved by reducing the denaturation of soluble proteins in the meal. Intensification of the process with the present invention is explained as follows: the treatment of the crushed solid material with a B / M emulsion ensures a quick uniform distribution of the extractive agent and water in the material. In this case, the emulsion disintegrates, in so far as the non-polar solvent, which is the external phase of the emulsion, is saturated with oil, located in the pores of the gel gel structure. At the end of the process, the emulsion completely disintegrates, where the oil is diffused in a non-polar solvent and the mixture of surfactant with water is localized in the gel portion of the cement, which gives it a readily deformable form. It is sufficient to pass the thus treated mcr through a single matrix, where it is pressed in, so that the solid content of the material is below 2% in terms of absolutely dry matter.
