| Abstract | A solar tunnel heat pump dryer was designed, constructed and tested for drying cocoa beans. The dryer consists of heat pump, single pass flat plate solar collector with fin, drying tunnel, turbine ventilator and blower. As much as 48 kg of cocoa beans with the moisture content of 67% wet basis was reduced the moisture content to 8.6% wet basis needed 20 hours whereas the moisture content of cocoa beans was reduced to 26 % wet basis using open sun drying in the same period. The minimum and maximum of the drying rate and the thermal efficiency of dryer were estimated of about 0.12 kg/h and 2.91 kg/h, 4.39% and 37.79%, and in average are 1.31 kg/h and 19.87%, respectively. The drying of cocoa beans have two drying periods, namely, the constant drying rate period and the falling rate period. Result shows that this dryer is capable of drying cocoa beans quickly because of the high drying rate. Also, the quality of cocoa beans in term of colour is using dryer were better than using open sun drying, because the short drying time, the products have no contamination of dust, dirt and other pollutants. |
