In many countries of the world, the use of solar thermal systems in the agricultural area to conserve vegetables, fruits, coffee and other crops has shown to be practical, economical and responsible approach environmentally. Solar heating systems to dry food and other crops can improve the quality of the product, while reducing wastes produce and traditional fuels - thus improving the quality of life. However the availability of good information is lacking in many of the countries where solar food processing systems are most needed. This work presents the performance of several individual, medium and large-scale food processing systems, which incorporate solar drying. A general purpose of solar crop dryer for drying of various agricultural products such as coffee, fruits, Vegetables, cereals, etc, is simulated. The simulated solar dyer consists of the solar air heater ( solar collector) which uses low emissivity glass cover, weather data, and an integrated dryer chamber attached to the collector where the products to be dried are placed.
