For year-round processing independent of the weather, modern operations use improved multi-crop dryers. These highly adaptable systems consist of three main parts: a combustion chamber, an efficient heat exchanger, and an insulated drying chamber. They can run on electricity, gas, or clean-burning kerosene stoves.

To prevent heat loss and maintain high energy efficiency, these dryers feature double-walled construction. The outer shell is built from durable coated mild steel, while the inner chamber and tray holders are made from food-grade stainless steel to ensure absolute food safety.
