Description
Technical field
The present invention relates to a kind of cereal cooling dryer.
Background technology
As everyone knows, in the cereal storing process, need suitable low temperature environment, so that cereal is in resting state, be unlikely to germinate, also can reduce the respiration of cereal itself simultaneously, prevent that the consumption of cereal self-energy is too much.Described low temperature generally is to maintain about 10 degrees centigrade.All need to be equipped with grain cooling machine in bulk storage plant or special cereal deposit base for these reasons.The effect of described cooler is that the cereal heap is lowered the temperature, and makes the temperature of cereal heap not be higher than 10 degrees centigrade.Grain cooling machine of the prior art only has refrigerating function.When reality is used, be not higher than 10 degrees centigrade though can control the temperature of cereal heap, but under this temperature, insect in the cereal heap still can survive and mobility unaffected, so grain cooling machine of the prior art in use, can not be extremely except the insect in the cereal heap, insect can be destroyed cereal.Be exactly that grain cooling machine of the prior art does not possess drying function in addition, can not remove the moisture in the cereal heap, the cereal heap becomes damp and rotten easily.In sum, there is the weak point that can not remove the insect in the cereal extremely and can not remove the moisture in the cereal in grain cooling machine of the prior art.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of energy to kill the cereal cooling dryer that can also remove the moisture in the cereal except the insect in the cereal simultaneously by the high temperature in the drying course.
For solving the problems of the technologies described above, technical scheme provided by the invention is: a kind of cereal cooling dryer, and it comprises casing and power supply, casing is provided with controller; Also be provided with first regenerator volume, second regenerator volume and at least one working cell in the casing, described working cell mainly is in turn connected into closed circuit by first compressor, cross valve, first heat exchanger, throttle part, second heat exchanger and first gas-liquid separator by pipeline; Described first heat exchanger is installed in first regenerator volume, first air outlet, first return air inlet also are installed in first regenerator volume and are used for the air in first regenerator volume discharged to first pressure fan in the drying room; Described second heat exchanger is installed in second regenerator volume, second air outlet, second return air inlet also are installed in second regenerator volume and are used for the air in second regenerator volume discharged to the second outer pressure fan of drying room; Described power supply is connected with each consuming parts electric wire, and described controller is electrically connected with each electric-controlled parts.
After adopting above structure, the present invention has following advantage: by the combination of first gas-liquid separator, first compressor, second pressure fan, first heat exchanger, second heat exchanger, device for drying and filtering, throttle part and cross valve, again in conjunction with the control of controller.Described cereal cooling dryer has cooling and two kinds of functions of oven dry desinsection, when needs are lowered the temperature to the cereal heap, unit moves with refrigeration mode, ringing by refrigerant, make first heat exchanger that the heat absorption of the air in first regenerator volume is made air cooling-down, and the air after will being lowered the temperature by first pressure fan is sent into the cereal heap from first air outlet, air at room temperature in the middle of this process in the warehouse can constantly enter first regenerator volume from first return air inlet, sent in the cereal heap by supporting airduct after the heat exchange cooling by heat exchanger, operational mode in this process in second regenerator volume is identical with pattern in first regenerator volume, and just this moment carried warmed-up air through supporting airduct by second heat exchanger outside the warehouse.When needs are dried desinsection to the cereal heap, unit moves with heating mode, ringing by refrigerant, make the release of the air of first heat exchanger in first regenerator volume make atmosphere temperature rising, and the air after will being heated up by first pressure fan is sent into the cereal heap from first air outlet, air at room temperature in the middle of this process in the warehouse can constantly enter first regenerator volume from first return air inlet, sent in the cereal heap by supporting airduct after heat exchange heats up by heat exchanger, operational mode in this process in second regenerator volume is identical with pattern in first regenerator volume, just this moment carried desuperheated air through supporting airduct by second heat exchanger outside the warehouse, when temperature is controlled the insect that can kill under the situation of not damaging cereal about 50 degree and after keeping a period of time in the cereal, and this temperature just can make being evaporated of water effective in the cereal, can remove the moisture of cereal, prevent that cereal from becoming damp and rotten.
As preferably, be provided with two working cells in the described casing.Two working cell operating efficiencies are higher, can well tackle large-scale cereal heap.
As improvement, on described second heat exchanger defroster is installed, described defroster is connected with power cable, and described defroster is electrically connected with controller.This structure can effectively solve and use the oven dry insecticidal function in winter, and the frosting phenomenon that second heat exchanger produces during to outdoor eliminating cold wind is to ensure entire machine stable operation in low temperature environment.
As improvement, the bottom of described casing is provided be used to the roller that casing is moved freely.It is more convenient that roller structure makes that machine moves.
