Principle of freeze drying

The principle of operation of the refrigeration dryer is to separate water vapor from the air through the use of refrigeration technology, this is called the principle of moisture separation. The dehumidification stage will obtain dry air of 10 degrees Celsius.

The dry air after the dehumidification process is put into the air chamber and run through the air compressor. At this time, the dry air reaches about 10 degrees Celsius, entering the air chamber with a temperature of about 20 to 50 degrees Celsius. The clear difference in temperature and pressure between the air and the product in the drying chamber will gradually absorb the water present in the drying chamber. product, from which the product gradually dries due to the evaporation of water vapor.

The humid air in the drying chamber will be removed through the dry filter, passing through the indoor unit to return to the original step.

The whole process takes place in a continuous freeze dryer, forming a recirculation, which provides a fast and stable freeze drying process. It is this principle that helps products lose only water, dry quickly without any impact on nutritional value, color or taste.

Drying products with a cold dryer will help bring high hygiene and safety because they are not contaminated with bacteria from the environment. Especially, cold drying technology helps to dry products quickly, usually 10-20 times faster than conventional heat drying methods.

Advantages of SUNSAY refrigerated dryer:

– Preserve product quality: Because the product is dried at a low temperature, it does not affect the color, does not change the properties, and retains the color and flavor much better than hot drying.

– Preservation of product taste: For some products with odors or essences, the loss rate is reduced because the system is completely sealed.

– Ensure the highest hygiene: The drying system is completely closed, does not exhaust air, does not suck in outside air. Hygiene.

– Shorten drying time: The air is dried out, so the drying process takes place faster, usually from 6 to 9 hours. For products because of an undesirable drying process factor that dries quickly, a longer drying time may be possible.
