Abstract

The invention provides a degumming method by virtue of a gas-liquid-solid three-phase magnetically stabilized fluidized bed. By investigating operating parameters of the magnetic fluidized bed reactor, the determined optimum operating parameters of the gas-liquid-solid three-phase magnetically stabilized fluidized bed are as follows: the magnetic field strength is 0.0015-0.0025T, the liquid flow rate is 0.0020-0.0030m/s and the gas flow rate is 0.015-0.025m/s. According to the magnetic three-phase fluidized bed reactor, nanometer magnetic enzyme environmental temperature is 50-60 DEG C, the pH is 6.0-8.0 and the amount of a boric acid buffer is 0.8-1.2mL/100g oil and the content of phosphorus and free fatty acid in oil is respectively 8.83mg/kg and 0.9783g/100g. The continuous degumming is finally achieved in the gas-liquid-solid three-phase magnetically stabilized fluidized bed and a solid foundation is laid for the actual industrial production.

Description

technical field [0001] The invention relates to the field of oil processing, in particular to the research on a degumming method using a gas-liquid-solid three-phase magnetically stabilized fluidized bed. Background technique [0002] Oil is an indispensable food for human survival, and the oil processing industry has also attracted much attention. With the development of the oil industry and people's further understanding of the principles of oil processing, new progress has been made in oil processing technology. Oil degumming is one of the main processes of oil refining. Degumming is to remove peptized impurities in oil, and the main component is phospholipid. With the advancement of degumming technology, a good degumming effect is the prerequisite for physical refining of vegetable oil. Incomplete degumming will increase the burden on subsequent processes, and in severe cases will cause coking damage to equipment, affecting the quality of oil and the economic benefits of...
