Description

TECHNICAL FIELD

[0001] The utility model relates to oil and fat deep processing technical field, concretely relates to an ester exchange oil and fat treatment device. BACKGROUND

[0002] In the existing oil and fat ester exchange process, sodium methoxide is widely used as an alkaline catalyst due to its high catalytic efficiency and mild reaction conditions. Traditional processes usually use an acidic aqueous solution as a reaction terminator, such as a 10% citric acid aqueous solution, to neutralize the alkaline catalyst and terminate the reaction. In the subsequent purification stage, multiple water washing operations are required, including adding excess pure water for mixing and shaking to dissolve residual catalyst and by-products, followed by static separation and filtration of the aqueous phase.

[0003] However, this process has the following technical defects: (1) the large interfacial tension between oil and water results in low separation efficiency, requiring extended static time or increased centrifugal assistance, significantly reducing production efficiency; (2) multiple water washing processes can form stable emulsions, increasing product loss; (3) it is difficult to completely remove dissolved monoglycerides, diglycerides, and other by-products in the aqueous phase, and trace amounts of sodium ions and citrate may cause oil oxidation deterioration; (4) a large amount of organic wastewater is generated during the treatment process, increasing the cost of subsequent water treatment. These problems collectively result in technical bottlenecks such as insufficient purity (usually less than 98.5%), dark color, and poor storage stability of the final product, making it difficult to meet the quality requirements of ester exchange oil and fat in high-end food and cosmetic fields.
