Vacuum System Assists the Fermentation of Lactic Acid Bacteria

    The freeze-drying method is currently the most effective and common preparation method for preparing lactic acid bacteria. It actually refers to vacuum freeze-drying treatment. Generally, dairy product manufacturers will load the ferment into the vacuum freeze-drying machine for freeze-drying, to ensure that lactic acid bacteria or other probiotics have sufficient vitality and effectiveness in future applications.

Fermentation of Lactic Acid Bacteria

    Vacuum technology is not only widely used in industrial production, but also in the food industry. For example, our common yogurt, in its production process will also be applied to vacuum technology. Yogurt is a dairy product fermented by lactic acid bacteria. And Lactic acid bacteria have many benefits for the human body. They can promote the balance of gut microbiota, enhance immunity, and reduce cholesterol. Therefore, how to efficiently prepare lactic acid bacteria has become an important issue. 

    The freeze-drying method is currently the most effective and common preparation method for preparing lactic acid bacteria. It actually refers to vacuum freeze-drying treatment. Generally, dairy product manufacturers will load the ferment into the vacuum freeze-drying machine for freeze-drying, to ensure that lactic acid bacteria or other probiotics have sufficient vitality and effectiveness in future applications.

    Vacuum freeze-drying machines inevitably equip vacuum pumps to achieve vacuum. Once, one of our customers who specializes in yogurt drinks, mentioned that when he using a vacuum freeze-drying machine, the vacuum pump was always inexplicably damaged. Do you know why? Because the vacuum pump sucked in corrosive acidic gas. Vacuum pumps are precision equipment. If there is no vacuum pump filter for filtration during operation, the vacuum pump will -soon be corroded by acidic gases.

To solve the customer's problem, we first equipped the vacuum pump with a dust filter based on the working conditions of the vacuum freezing tank, and then selected a filter material with anti-corrosion to ensure that the filter can effectively protect the vacuum pump for a long time. Besides, we customized a filter based on his other requirements. In the end, it perfectly matched and solved the problem.
