White vinegar is often produced using the alcohol liquid fermentation process. Due to the complexity of the fermentation process, many by-products are generated, such as macromolecular pigments and colloidal impurities, resulting in poor transparency of the vinegar. After prolonged storage, it may become cloudy. 

      Traditional diatomite filtration can only achieve temporary clarification. Because the filter cake layer formed by diatomite is uneven, and due to differences in operators' visual standards, it is highly likely that the filtered product will develop sediment after storage. To decolorize fermented white vinegar and prepare colorless white vinegar, traditional flocculants and activated carbon can achieve some decolorization effect, but they cannot completely remove pigments. To achieve a colorless appearance, a large amount of activated carbon and flocculants are required, along with multiple decolorization treatments. However, after multiple rounds of activated carbon adsorption, the aromatic substances and other components in the white vinegar are significantly reduced, leading to failure in meeting the standards for white vinegar. 

        Introduction to Membrane Filtration Equipment for White Vinegar Clarification and Decolorization: "Jiahe Filtration" has designed and manufactured specialized clarification equipment for white vinegar and decolorization equipment tailored to the characteristics of white vinegar. The main principle involves using the selective precision sieving of polymer membrane materials to remove these macromolecular impurities in one step. Through the cross-flow operation process, impurities are less likely to clog the membrane surface, extending the service life of the filtration equipment.

Equipment Features: 

 （1）Advanced nanoscale separation membrane with strong selectivity, thorough impurity removal, and uniform pore size distribution, resulting in clear and transparent filtrate after filtration; 

 （2）Cross-flow operation of white vinegar raw liquid on the membrane surface effectively reduces clogging of filtration elements; membrane elements can be repeatedly cleaned and restored, with a long service life; 

 （3）The filtration and separation process is purely physical, with no impact on the taste and flavor of white vinegar; 

 （4）The entire separation and filtration process is controlled at room temperature or low temperature, minimizing impact on product quality;

 （5）The filtration equipment features a modular design, making it easy to integrate into existing production systems; 

 （6）The product is clear and transparent, with no cloudiness even after prolonged storage.
