Heli-drying units for drying fruit and vegetable products under conditions of Uzbekistan

Abstract

The article presents the results of research of solar drying plants for mechanization of preparation processes and organization of the drying process with a minimum energy consumption and maximum quality of finished products. The greatest effect is achieved when drying to low humidity, for example, drying fruit to a humidity of 2.5-3% is achieved in 4-16 hours, depending on the properties of the material to be dried. During vacuum drying, the rate of moisture evaporation increases, since the rate of moisture removal is proportional to the difference in water vapor pressure at the surface of the material and in the surrounding space. The efficiency of the process increases due to the lack of heat loss with the outgoing air.
