Double-layer design baking improves both baking speed and energy savings. The working principle of the material drying system is to use the coal-fired hot air stove to heat the cold air from the outside into the furnace, and then the hot air is extracted and sent into the drying pool through the work of the exhaust fan. The double-layer drying pool divides the upper and lower layers and the two layers The peanuts are dried at the same time, the moisture is discharged from the upper layer, and the seeds are dried to a half dry state. After the pneumatic valve is opened and closed, the horn box is opened, and the seeds are dropped on the lower layer for baking at high temperature. After baking, the seeds are put into the hopper through the pneumatic valve, and then transported to the next process via the conveyor belt. At the same time, adding the seeds to the upper layer is equivalent to covering the breathable woven fabric during the traditional baking, which effectively avoids the loss of the spice taste during high-temperature baking and improves the spice utilization efficiency. The observation window is provided in the lower layer of the drying box to make it easy to observe the state of peanuts.

The height of the production workshop is not enough, it can be customized according to the actual situation, and other materials can also be dried. According to the daily production volume, single or multiple series drying can be adopted. It is a new type of economical simple drying equipment. It can be equipped with a skillet and the wok becomes a flow production line.
