Description
Technical field
The present invention relates to silo aeration-drying technologies, particularly relate to double stage heat pump runner combined type silo drying system.
Background technique
For grain during storage, the variations such as grain feelings such as temperature, humidity, moisture, insect pest influence whether the matter of grain
Amount and quantity.Temperature in silo is higher, higher temperature influence whether storage grain quality, therefore, it is necessary to silo into
Row ventilation processing, existing ventilating system energy consumption is high and when outside air humidity is larger, and the entrance of outside air causes
The mildew of grain in silo.
With a series of implementation of Huinong's policies of country, the area for promoting grain large-scale planting, concentrator to receive is increasingly
More, peasant sells the wheat newly harvested without drying, and grain depot is increasingly difficult to the quality control of stored grain, this just leads
The phenomenon that causing high moisture grain directly to put in storage.In order to guarantee the safe storage of grain, it is necessary to appropriate drying process is carried out to it,
And existing drying means, such as carrying out drying using dryer needs to consume a large amount of fossil energy, and it is at high cost, and gravity-flow ventilation
