Secagem de raspas de mandioca com ar forçado e auxílio de coletores solares.

Abstract

Drying is the most expensive unit operation for produ cing cassava chips, used in the animal feed industry. Because it is necessary to evaporate 1600 kilograms of water to produce one ton of 13% moisture chips, the only economical way of obtaining those chips is by using solar energy. In the present research work experimental and simulated results of cassava chips drying with forced air, heated by solar collectors are presented. The results show that the use of for ce convection and solar collector may be an efficient and econo mical way of producing cassava chips. The computer model, adap ted for predicting the drying process, is a useful tool for de signing a system under specific conditions.
