Investigation of the Temperature Dependence of a Product Dried in a Solar Dryer on Its Moisture Content

Abstract

This paper presents the results of liquid-viscous temperature studies of agriculture products during in drying process in a solar-drying installation of a radiation-convective type. And also, the results of the temperature of the glass coating of the drying chamber during the day at different periods of the year. The outer surface temperature dependences of the drying chamber glass enclosure in July and October on the density of solar radiation and from the ambient air temperature are given. Research indicators have been determined that, other things being equal, the temperature of the dried product is significantly affected by their absorption capacity. The indicators of the research that in other equal conditions their observing feature significantly effects on temperature of drying products are defined absorption capacity.
