A schematic of a direct solar dryer. Direct solar dryers expose the substance to be dehydrated to direct sunlight. Historically, food and clothing was dried in the sun by using lines, or laying the items on rocks or on top of tents. [2] In Mongolia cheese and meat are still traditionally dried using the top of the ger (tent) as a solar dryer. [3]
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.

Various dried foods in a dried foods store An electric food dehydrator with mango and papaya slices being dried. This is a list of dried foods.Food drying is a method of food preservation that works by removing water from the food, which inhibits the growth of bacteria and has been practiced worldwide since ancient times to preserve food.
Canisters are commonly filled with silica gel and other molecular sieves as desiccants in drug containers to keep contents dry Silica gel in a sachet or porous packet. A desiccant is a hygroscopic substance that is used to induce or sustain a state of dryness (desiccation) in its vicinity; it is the opposite of a humectant.
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.
