Condensation drying of air and indirectly of foodstuffs (fruit, tea, mushrooms and such) is the most energy saving way of removing water from different materials, foodstuffs being one of them. It works on the heat pump principle- by cooling on a steamer temperature below dew point is reached, due to which the surface of the steamer becomes wet with moisture from the air. The heat extracted from the air goes immediately back to the same air, with the help of electric energy needed for the operation of the compressor, 20-30% more heat is generated. There's more than enough heat for the temperature in the well insulated drying container to be maintained; this makes possible safe and quality drying of food. After the processing the air is lead over the grates with the drying materials. During this process the air accumulates moisture and goes back to be processed in the drying unit. The process goes on continuously until the desired dryness is reached.

Due to relatively low drying temperatures the dried food preserves the quality; all the characteristics of fresh – such as the taste, aroma and color – are preserved.

The dryer is compact, it is made of stainless materials; the insulation is good (70mm polyurethane foam). It is equipped with a compact cooling/heating apparatus attached to the ceiling of the container. Energy consumption is 400/500 W per hour of operation. Regulation is electronic; drying temperature can be set, which makes possible to adjust the drying with regard to different foodstuffs. The water outlet is in the form of plastic attachment which can be attached to the sewing system or a plastic container.
