Description
Technical field
The present invention relates to drying equipment technical field, more particularly to a kind of grain drying device.
Background technology
Cereal is to need cereal to be dried processing from harvesting to the process of storage, in order to cereal following process or
Person stores for a long time.And the more traditional drying machine by burning fuel mode of crop dryer of heat-pump-type, pollute small, energy consumption
The advantages of low, at low cost, is particularly evident, and therefore, the prior art already has more and more heat-pump-type crop dryers for substituting
The drying machine of traditional burning fuel mode.
The grain drying machine of the prior art mainly includes heat pump and drying tower, and heat pump is by gaseous refrigeration by compressor
The gaseous refrigerant of agent boil down to high temperature and pressure is then delivered to after condenser heat dissipation as the liquid refrigerant of normal temperature high voltage,
Heat that condenser distributes during this is delivered to granary by wind turbine, and then liquid refrigerant is through capillary, into evaporator,
Due to refrigerant from capillary reach evaporator after space increase suddenly, pressure reduces, and the refrigerant of liquid will vaporize, become
The refrigerant of gaseous state low temperature, so as to absorb a large amount of heat, evaporator will turn cold, and the water vapour in air encounters cold evaporation
Water droplet will be condensed into after device.Particularly under winter or the north colder environment, often condensation frosts on evaporator.
Therefore existing heat-pump-type crop dryer needs to set defroster, and a kind of method is to make refrigeration by four-way valve
Agent is at the flow direction of condenser and evaporator and drying machine normal processes state on the contrary, the refrigerant for passing through high temperature and pressure
It flows into evaporator and reaches defrosting effect, but since the heat transfer effect of condenser and evaporator is converted, supply granary originally
The condenser of interior dry-heat air is converted to offer cold wind, this process will be such that cold wind pours in down a chimney to granary, destroys former in granary
Some dry environments；Another method is to set resistance wire on an evaporator, and resistance wire is connected to controller, passes through resistance wire
It defrosts to evaporator heating, although this method will not destroy the dry environment in baker, increases the consumption of resource.
The present invention is therefore.
