Промышленный Дегидратор для трав и овощей вакуумная сушильная машина

The vacuum dryer machine is the mass transfer operation in which the moisture present in a substance, usually a wet solid, is removed by means of creating a vacuum. Vacuum drying is generally used for the drying of substances which are hygroscopic and heat sensitive, and is based on the principle of creating a vacuum to decrease the chamber pressure below the vapor pressure of the water, causing it to boil. With the help of vacuum pumps, the pressure is reduced around the substance to be dried. This decreases the boiling point of water inside that product and thereby increases the rate of evaporation significantly.

The materials to be dried are kept on the trays inside the vacuum dryer machine and pressure is reduced by means of vacuum pump. The dryer door is tightly shut and steam is passed through the space between trays and jacket so that the heat transfer occurs by conduction. Water vapors from the feed is sent into the condenser and after drying vacuum pump is disconnected and the dried product is collected from the trays.
