Low Temperature Grain Drying with Solar Heat

Solar grain drying tests at Kansas State University were initiated in 1957 by Davis, Zachariah, and Lipper (Lipper and Davis, 1959) to compare solar sup­ plemented drying with natural air drying. In 1960 a solar collector using a clear and black polyethylene plastic was tested by drying of sorghum. The collector was modified and tested in 1961 and 1962. In 1963 a lightweight

Solar Drying - an overview ScienceDirect Topics

Solar tunnel dryers (Fig. 1.2.5) consist of a solar air heater and a tunnel dryer, which are arranged in series. Air heater and tunnel dryer are covered with either a transparent foil, polycarbonate double-skin sheets or glass sheets. The transparent cover is tilted to drain water. A black metal sheet is used as absorber. On the backside, any kind of water and heat resistant

Solar dryer Climate Technology Centre Network 1183419

Principally, solar dryers can be categorized into three groups: a) natural convection dryers, which are solar dryers that use the natural vertical convection that occurs when air is heated and b) forced convection dryers, in which the convection is forced over the food through the use of a fan and c) tunnel dryers. While several different designs of the solar dryers exist, the basic
