Design Specifications

The dryer has a solar collector, metal frame, and a chamber to place the food on racks. It requires an area of 11 m2 for installation. The main source of energy is sunlight (some food dryers have a gas backup system) which is captured by the 1.3 m2 collector and transmitted to the drying chamber through a coil which contains 60% water and 40% anti-freeze. The water vapor from the product (fruits, vegetables, grains, etc.) builds up internal pressure in the chamber which is regulated through a valve to warm up the pulp initially. The stainless steel chamber has a 10 kg to 20 kg daily drying capacity, a metal support, exhaust valve, and a thermostat.
