Freeze drying machine

Freeze drying machine

A freeze dryer uses physical principles to freeze the moisture in compressed air below the dew point, allowing it to separate from the air. Due to the freezing point temperature of water, theoretically its dew point temperature can be close to 0 degrees. In reality, a good freeze dryer generally has a dew point temperature of around 5 degrees.

Product features of refrigerated dryer: The product has air cooling, water cooling, and mixed cooling methods. The water-cooled pre cooler and condenser of the refrigeration system before the water-cooled dryer adopt cooling water cooling method, mainly used in situations with good water supply conditions, high intake temperature, and large air processing capacity. Due to its less affected by environmental temperature factors, the dew point of the outlet air is relatively stable. The condenser adopts a shell and tube type, with high-efficiency toothed tubes for the heat exchange tubes. The cooling water flows through the tube side, which is easy to clean due to scaling over time. Freon flows through the shell side, ensuring that the condensation effect remains in good condition for a long time.
