Embodiment 1

[0018] As shown in the attached figure, the hydrated and degummed double-low rapeseed oil is pumped in and heated by a heat exchanger. % citric acid aqueous solution, 2%~9% NaOH aqueous solution and oil (citric acid and sodium hydroxide adding ratio are 2: 3~4, and the addition of citric acid is 0.03%~0.05% of the oil weight in the mixing tank, with Weight) After being fully mixed in the intensive mixer, it is pumped into the blending tank, the temperature of the oil-water mixture is controlled between 50-90°C, and the oil-water emulsion is blended at a stirring speed of 100-200r / min for 10-30min. At this time, the oil-water emulsion The pH value of the mixture is between 4 and 6. The reconciled oil-water emulsion passes through a heat exchanger, and the oil temperature is adjusted to 20-70°C. After being mixed with the aqueous solution of phospholipase A1 (the addition amount is 50-200U / kg oil), it is pumped into the ultrasonic degumming together. tank, adjust the speed of t...

Abstract

The invention relates the ultrasonic degumming method, comprising adjusting emulsion, hypersonic auxiliary enzymolysis and hypersonic auxiliary hydrating. The method comprises the following steps: after biological enzyme treatment fat, carrying out low water hydrated phase, carrying out ultra-audio wave radiation, and then carrying out water-oil separating. The invention can shorten treatment time and enzyme content, improves the boundary effect between oil and water, reduces biological enzyme density, advances the gelatinous hydrating, improves detaching efficiency, modifies weight of boil-off gum content, and reduces equipment investment and oil consumption, reduces cost.

Description

technical field [0001] The invention relates to a method for degumming oil, in particular to a method for strengthening degumming by ultrasonic radiation in the process of treating oil with biological enzymes, which is used to accelerate the degumming speed of biological enzymes and the separation efficiency of oil-water slag phase. Background technique [0002] The methods of oil degumming include hydration degumming, acid refining degumming, adsorption degumming, thermal polymerization degumming and chemical reagent degumming, etc. The refining of edible oils and fats is generally carried out by hydration degumming to remove the hydration phospholipids in the crude oil. To remove the non-hydratable phospholipids in the oil, it is necessary to add chemical substances such as phosphoric acid and NaOH to convert the non-hydratable phospholipids in the oil into hydratable phospholipids, and then remove them by hydration degumming. Now, a new method has emerged for the removal...
