摘要：Indirect type solar dryer with forced convection was constructed and fabricated. Solar drying has proved to be technically and economically valuable. The thermal performance of the drying chamber was studied by passing hot air through the connecting pipes from the solar collector. It is observed that the dried product is free from undesired contaminant. Small quantity of coffee beans are dried quickly. They are also more efficient than patio drying technique because their hotter drying temperature dry coffee beans at a faster rate. Drying the coffee beans at a faster rate was one of the main objective which was validated with experimental results. The product is designed to its maximum optimal functioning at a very low cost.Our machine is capable of drying coffee beans in small quantity quickly. It is capable of drying at a faster rate than other means of drying process.
