Solar dryers not only make the drying faster, it also prevents dust, pathogens, bird droppings, and interference of external agents that affect the quality of the food. Food items such as fruits, vegetables, spices and other items once dried in solar can be stored for longer period of time.
Some solar food dryer designs employ a separate solar collector to generate the heated air, which is then directed into a food chamber or cabinet. This type of solar food dehydrator is called an indirect solar dryer. [7] [8] [9] Other designs combine the collector and food cabinet and allow direct heating of food (these are called direct solar ...
In addition, another widely used industrial method of drying of food is convective hot air drying. Industrial hot air dryers are simple and easy to design, construct and maintain. More so, it is very affordable and has been reported to retain most of the nutritional properties of food if dried using appropriate drying conditions. [6]

Parabolic Solar Cooker. A solar cooker is a device which uses the energy of direct sunlight to heat, cook or pasteurize drink and other food materials. Many solar cookers currently in use are relatively inexpensive, low-tech devices, although some are as powerful or as expensive as traditional stoves, [1] and advanced, large scale solar cookers can cook for hundreds of people.

During his tenure as CEO of NSPRI, the institute also designed and constructed a 5-tonne parabolic solar dryer for grains, fruits, and vegetables. [ 9 ] At the expiration of his tenure at the NSPRI, Peters returns to the National Open University of Nigeria on 7 January 2019 and was subsequently elected as Vice-Chancellor of the University, and ...
Hybrid solar drying systems can also be used for a continuous drying process. In a hybrid solar drying system, solar energy is utilized during daylight and energy from burning biomass is used when sunlight is not sufficient or during night time. [6] Sun drying requires little more than racks and sufficient sunlight.
