Degreasing device of corn oil and technique thereof

Abstract

The invention relates to a degreasing device of corn oil and a technique thereof; the device comprises a crystalizing tank, a degreasing filter, a grease paste oil tank, a cyclone hydraulic separator, a steam separator, a solid grease melting groove, a refrigerating unit, a press, a gas separating packet and a PLC control cabinet. The degreasing device is simple in structure, and the whole technical process is free from waste water and solvent pollution; the filtering needs not dismount devices, thus the working environment is improved; due to the PLC full-automatic control, the device reduces the labor cost and lightens the labor intensity; after applying physical squeezing, the flavor and nutrition of the corn are maintained, the corn oil is rich in vitamin E and phytosterol, and contains over 80% of unsaturated fatty acid, wherein the content of linoleic acid is higher and up to over 50%, thus the taste of the corn oil is greatly improved, and the corn oil is suitable for more extensive crowd.

Description

technical field [0001] The invention belongs to the technical field of degreasing, and in particular relates to a degreasing device for corn oil used for removing solid fat in corn oil production and a process thereof. Background technique [0002] Corn oil, also known as corn oil and corn germ oil, is an oil extracted from corn germ. The fat content of corn germ is between 17% and 45%, accounting for more than 80% of the total fat content of corn. The fatty acid in corn oil is characterized by unsaturated fatty acid content as high as 80%~85%. Corn oil itself does not contain cholesterol. It has a dissolving effect on the accumulation of cholesterol in the blood, so it can reduce the hardening effect on blood vessels. It has a positive preventive effect on senile diseases such as arteriosclerosis and diabetes. Due to the function of natural compound vitamin E, it has obvious curative and preventive effects on heart disease, thrombophlebitis, reproductive dysfunction, mus...

AI Technical Summary

Problems solved by technology

[0003] The refined oil produced from corn oil by conventional processes such as degumming, deacidification, drying, decolorization, deoxidation, deodorization, etc. will often appear turbid during storage, especially in winter, the main reason is that the refined oil Contains a small amount of lipids and components with large molecular weight, the content is generally 0.1%-0.2%, these components will condense out of the oil at low temperature, causing flocculated or cloudy suspended matter in the oil, affecting the appearance of the oil Image, while corn oil with high fat content is cooled, crystallized, and degreased, which is characterized by high fat content (0.01-10%), complex process requirements, and long process
