EXPERIMENTAL RESULTS OF AN IMPROVED SOLAR FRUIT DRYING DEVICE

Аннотация

In this article, surfaces that form the phenomenon of natural convection in a fruit dryer are selected. It has been revealed that the efficiency of the dryer is higher when the first and upper windows are open, and the second and third windows are closed. Moreover, when the temperature difference reaches T_1,5,sr=2,4°C, the flow of warm air begins to move in the dryer (natural convection). For an efficient drying process in a plant, natural convection must occur at low temperatures. The low temperature (T_4,sr=44.85°C) in the first part of the installation where the product is located (point 4) did not affect the quality of the product.
