Industrial Freeze Drying Machine

Because of its ability to dry items at low temperatures, freeze dryers are popular and widely used in food, cosmetics, pharmaceuticals, biological products, pet treats and other fields. However, the operation of the freeze-drying machine also needs attention. 

The following summarizes the main matters of the freeze-drying process of the industrial freeze-drying machine:

1. The freezing temperature should be guaranteed to be below the triple point, otherwise in a vacuum environment, the boiling of the liquid will make the surface of the product uneven;

2. During the sublimation drying process, maintain sufficient vacuum. Insufficient vacuum degree or insufficient heating may lead to incomplete moisture sublimation of the finished product and high moisture content;

3. If the heating is too fast, the heating is uneven or the pre-freezing is not complete, the product will be partially liquefied during the sublimation process, and the bottle spray phenomenon will occur under reduced pressure conditions, making the surface of the product uneven;

4. Keep the sublimation temperature unchanged;

5. The quick-freezing process is faster. The faster the ice crystals are generated, the smaller the impact on the structure of the item.

We focus on the research and development, production and sales of vacuum freeze-drying technology. With "vacuum freeze-drying machine" as the core product, we have formed a series of products and targeted solutions for scientific research experiments, medical and food industries, different scales and different applications. , is an influential supplier of vacuum freeze drying equipment and targeted solutions in China.
