Action fans and centrifugal fans in mechanical ventilation in a grain temperature due to the temperature difference between the larger and axial fans 380v, the first time to choose the ventilation during the day, in order to reduce the gap between food mild temperatures, reduce condensation occurs. After ventilation as much as possible at night, because this is a cool airy main evening relatively high atmospheric humidity, low temperature axial fan t35, so that reduces moisture loss sidewall axial fans, but also make full use of the low temperature at night, improved cooling effect. When retarder ventilation axial fans, axial fans due to the small amount of wind, in addition to food is a poor conductor of heat, ventilation prone to individual parts of the initial slow ventilation axial fans, ventilation continued with full warehouse grain temperature will gradually Slow food were balanced ventilation must be vibration sieve cleaning, and food into the impurity regions must be promptly cleaned compartment caused the automatic classification, otherwise easily lead to uneven local exhaust ventilation. Proof axial fans, axial fans, ventilation equipment from Plumper Plumper Shandong Dezhou ventilation plant. Dezhou Plumper ventilation plant (0) strong, credible, in Dezhou fan, ventilation equipment industry has accumulated a large number of loyal customers.
