摘要:
In this article a procedure for designing a multitray agricultural dryer, capable of producing uniform drying of product, is given. An analytical solution based on heat and mass transfer for air and product inside the dryer is used. In the solution, there is an attempt to keep the drying rates of the products on different trays constant during the whole drying period. This could be realized by changing the dryer shape and dimensions for every specific product in accordance with the conditions of the inlet air. It was found that a dryer of pyramidal shape is most suitable for fulfilling the requirement of good quality dried product. The method has been verified experimentally and shows good agreement with the analytical solution. Based on the obtained results, the design of a dryer for many kinds of fruits is obtained with the analytical solution.
