solar energy for crop drying
By reducing the rate at which air passes through a solar wall into a building, more heat is absorbed by the air, which results in a much high temperature indoors. One can increase the indoor temperature to such a high value that the solar wall can be used for crop drying. Solar heat is often the preferable choice for crop drying because this type of heating doesn't burn or harm delicate foods, which often occurs when using steam or burning fuels.
Installing a solar wall system is fairly easy to do. The system is mounted onto already existing structures and can utilize the fan system that is already present. Advantages for using solar heating for crop drying include:
