Problems solved by technology

In the prior art, the refining process of DHA / EPA oil is carried out at a low temperature lower than 200°C. In this type of oil refining technology, the heating and deodorization time are relatively long, usually more than 1 hour, and the whole process takes a long time. Once the temperature is not properly controlled, it is easy to cause different chemical changes and affect the quality of the refined oil
The entire refining process requires high temperature control, which is time-consuming and labor-intensive

Abstract

The invention discloses a high temperature refining system and a refining method for high DHA / EPA oil. The method comprises the following steps: conducting heat exchange on an original DHA / EPA oil material of 50-80 DEG C with discharging hot oil and rapidly heating to 150-210 DEG C; further heating the DHA / EPA oil of 150-210 DEG C to 200-260 DEG C; quickly introducing the DHA / EPA oil at 200-260 DEG C into a flash tower, carrying out flash evaporation by superheated steam and cooling the DHA / EPA oil to 180-220 DEG C after the flash evaporation; then conducting heat exchange on DHA / EPA grease and feeding cool oil and rapidly cooling to 90-110 DEG C; and quickly cooling the DHA / EPA oil of 90-110 DEG C to 30-60 DEG C by a cooling apparatus. The method provided by the invention greatly shortens the refining time, realizes good refining effect, and can effectively remove various volatile impurities and pollutants such as plasticizer, PCB and PCB analogs.

Description

technical field [0001] The invention relates to an oil refining system in the new technology of separating and extracting effective components of natural products, in particular to a high-temperature refining system and a refining method for high-DHA / EPA oil. Background technique [0002] Because the DHA / EPA oil will undergo chemical changes under high temperature conditions for a long time to generate harmful substances. In the prior art, the refining process of DHA / EPA oil is carried out under the condition of low temperature lower than 200°C. The heating and deodorization time of this kind of oil refining technology is long, generally more than 1 hour, and the whole process takes a long time. Once the temperature is not properly controlled, it is easy to cause different chemical changes and affect the quality of the refined oil. The temperature control of the entire refining process requires high requirements and is time-consuming and labor-intensive. Contents of the i...
