Cabinet Food Dryer For Multi Food Species

Mechanical Engineering

Drying in the sun is very economical. In an conventional drying we only have to spread the produce on a suitable surface and let it dry in the sun. Somebody has to stay at home throughout the drying period to chase off domestic animals, to remove the produce when the weather becomes too windy and dusty, or when it rains. The dried product is often of poor quality as a result of grit and dirt. The product is often unhygienic as a result of microorganisms and insects such as flies. A basic cabinet-type low-cost solar dryer can be constructed at home or by village artisans. It is made of wire-mesh cabinets in a wooden framework surrounded by a clear plastic sheet. The solar cabinet dryer type has a capable of drying 20 to 35 kg of fresh produce (depending on commodity) over a period of 3 to 4 days. Smaller portable models of the dryer can be constructed, depending on available funds for the dryer, construction and the purpose of drying (home consumption or marketing).This project research reports based on the automation in cabinet dryer for the safety of operator. This was operated by the using electricity as well as conversion of solar energy into electricity. The safety elements as well as the working elements operated on it. The dryer is protected by the used of RFID reader which can start the dryer and operate different range and controlled by the operator.
