The use of solar energy in drying perishable crops such as tomatoes is a good alternative to the problem post-harvest processing tropical eastern African countries. A review literature revealed that most crop systems developed during last five decades have small loading capacity and cannot operate night. Therefore, an integrated greenhouse dryer system [SGDS] with Clay-CaCl2 desiccan...

A mathematical model for the evaporation of a single droplet, subjected to convective drying in a spray dryer was developed to study the transient phenomena of particle formation. During the constant-rate drying period, the governing equations and boundary conditions were transformed into a form containing Peclet number, Pe, as the main controlling parameter. A numerical solution was developed ...

In this research a fuzzy model is developed for a rotary dryer. It is applied to the pilot plant rotary dryer located in the Control Engineering Laboratory at Oulu University. Firstly, a literature review looking at the current situation of fuzzy modelling and comparison of different methods is done. One modelling method is then applied to the building of the model from data. The rule parameter...

Abstract The lack of adequate techniques for food processing is among the reasons underlying losses and high levels hunger in Sub-Saharan Africa; application solar energy to dry agricultural products one potential solution. However, total replacement traditional uses still far from reality. Therefore, this study, we systematically review academic literature testing passive drying systems order ...

Drying via solar energy is an environmentally friendly and inexpensive process. For controlled bulk level drying, a greenhouse dryer the most suitable dryer. The efficiency of can be increased by using thermal storage. agricultural products dried in greenhouses are reported to higher quality than those sun because they shielded from dust, rain, insects, birds, animals. heat storage-based was fo...
