Problems solved by technology

[0002] At present, in order to preserve some crops, the dry storage method is usually used. At present, many workshops or self-employed people use ovens to dry crops. The existing ovens adjust the oven temperature by adjusting the exhaust air volume of the oven and setting the heater. To achieve the purpose of quickly drying agricultural products, however, there are still shortcomings in this drying method. The heat energy used in the drying process is discharged to the external environment through the exhaust pipe and is not fully utilized, resulting in environmental pollution and heat loss.
