Chap-Dryer

Unlike other poly-tunnel solar dryers in the market that use steel frames and metallic base plates, Chap-Dyer uses moisture resistant eucalyptus poles as frames and rough stone slates as a base. These materials are readily available in all parts of Uganda and very affordable, reducing the total cost of a dryer from $1,000 to $200 for an 18 cubic meter drying space. The use of stone slates instead of steel plates allows for the dryer to perform optimally during day time and night time, drying twice as fast as the standard poly-tunnel dryer in the market. Unlike steel frames that require precise engineering and fabrication for easy assembly on site, Chap-Dryer which uses eucalyptus and stones requires simple carpentry and masonry joinery techniques which takes less labor cost and minimal electric power cost as all components can be fabricated and assembled on site.
