Later, it was dried in the form of coal/fuel, but the temperature was too high, the nutrients of the pumpkin seeds were easily lost, and the taste was also changed. Some people now use gas boilers, electric drying, microwave drying, etc., but they all have certain defects, such as high drying costs.
