Figure 5.1: Improved solar cabinet dryerThe dimensional details of the cabinet dryer are presented in Figure 5.2. The designdetails of individual dryer parts are presented in the following sections.Dimensions are in mmFigure 5.2: Dimensional details of the improved solar cabinet dryer28
Solar CollectorThe flat plate air-heating solar collector, of size 1.6m x 2m, consists of an absorber,glazing, an outer box, an inner box. A 50 mm glasswool insulation is placed betweenthe two boxes. Corrugated aluminum sheet is used as the absorber plate, while theouter and inner collector boxes are made of GI sheets. A black coating is provided onthe absorber surface. The cover glazing is of four nos. of 4 mm thick window glass.The absorber and insulation materials are placed inside the inner GI box. The airinlet to the collector is fitted with a fine stainless steel wire mesh to keep insects out.Table 5.2: Construction materials used for the solar collectorSl.
