A review on thermal models for greenhouse dryers

This review paper appraisal the previous work on the thermal modeling of greenhouse drying systems. Thermal modeling plays a significant role in ideal design and development of the greenhouse dryer. It is also very useful tool in optimizing the drying parameters to enhance the performance of greenhouse drying systems under various modes of operation. The crop and greenhouse room air temperature, relative humidity inside greenhouse, drying rate, drying kinetics and drying potential can be estimated precisely from thermal modeling. This piece of work is a comprehensive review of various thermal modeling done by researchers for greenhouse drying systems. The greenhouse dryer can be designed for a given mass of crop as well as location of installation from energy balance equations. This review will be valuable and appropriate for further development of energy efficient greenhouse drying systems.
