Problems solved by technology

However, because the reaction requires high temperature and high pressure, the equipment requirements are relatively high. Generally, the existing high-pressure reactors perform batch reactions, which is inconvenient for sampling and analysis, and is also not conducive to industrial production; meanwhile, the water contains certain concentrations of ethanol in the hydrolysis process. The current process does not remove ethanol, which makes it difficult to prepare high-content EPA+DHA glyceride fish oil products in the later stage of the reaction

Abstract

The invention provides a continuous subcritical reaction device for ethyl ester fish oil hydrolysis, and belongs to the technical field of foods. The continuous subcritical reaction device for ethyl ester fish oil hydrolysis comprises a water storage tank, a reaction chamber with a water inlet and a water outlet, and a liquid storage box with a liquid outlet, wherein a circulating structure capable of recovering water flowing from the liquid outlet to the reaction chamber and recycling the water is arranged between the liquid outlet of the liquid storage box and the water inlet of the reaction chamber, a control structure capable of controlling the pressure and the temperature in the reaction chamber is arranged on the reaction chamber, and a recycling structure capable of recycling ethanol separated from a condensing and evaporating pot is arranged on the condensing and evaporating pot. The continuous subcritical reaction device for ethyl ester fish oil hydrolysis can be used for solving the problems of inconvenience for sampling and analyzing, disadvantage to commercial process and the like of the traditional batch-type precritical reaction unit, and has the advantages of realizing the control of hydrolysis temperature and pressure, effectively increasing the working efficiency, and the like.

Description

technical field [0001] The invention belongs to the technical field of food and relates to a continuous subcritical reaction device, in particular to a continuous subcritical reaction device for hydrolyzing ethyl ester fish oil. Background technique [0002] Subcritical water is high-temperature and high-pressure water that remains in a liquid state when the water is heated above 100°C and below the critical temperature of 374°C under moderate pressure. At this time, the properties of the water change greatly. On the one hand, its polarity decreases, the mass transfer resistance becomes smaller, and the solubility of fat-soluble substances increases; on the other hand, as it approaches the critical point, the acid-base catalytic ability of water is greatly enhanced, and acid-base catalytic reactions can occur to a certain extent , and because its properties are adjustable with temperature and pressure, the conditions required for the reaction can be designed according to the...
