Description
Technical field
The present invention relates to the cooling dryer of a kind of cereal.
Background technology
As everyone knows, in cereal storing process, need suitable low temperature environment, so that cereal in resting state, is 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 is generally to maintain 10 degrees Celsius of left and right.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 cereal heap is lowered the temperature, and makes the temperature of cereal heap not higher than 10 degrees Celsius.Grain cooling machine of the prior art, only has refrigerating function.In the time that reality is used, although can control the temperature of cereal heap not higher than 10 degrees Celsius, but at this temperature, insect in cereal heap still can survive and mobility unaffected, so grain cooling machine of the prior art in use, can not kill except the insect in 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 cereal heap, cereal heap easily becomes damp and rotten.In sum, grain cooling machine of the prior art exists and can not kill except the insect in cereal and the weak point that can not remove the moisture in cereal.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of and can kill the cooling dryer of cereal that can also remove the moisture in cereal except the insect in cereal simultaneously by the high temperature in drying course.
For solving the problems of the technologies described above, technical scheme provided by the invention is: the cooling dryer of a kind of cereal, and it comprises casing and power supply, casing is provided with controller; In casing, be also provided with First Heat Exchanger chamber, the second regenerator volume and at least one working cell, described working cell is mainly in turn connected into closed circuit by the first compressor, cross valve, First Heat Exchanger, throttle part, the second heat exchanger and the first gas-liquid separator by pipeline; It is indoor that described First Heat Exchanger is arranged on First Heat Exchanger, First Heat Exchanger is indoor be also provided with the first air outlet, the first return air inlet and for by air indoor First Heat Exchanger discharged to the first pressure fan in drying room; The second described heat exchanger is arranged in the second regenerator volume, in the second regenerator volume, be also provided with the second air outlet, the second return air inlet and for by the air in the second regenerator volume discharged to the second pressure fan outside drying room; Described power supply is connected with each consuming parts electric wire, and described controller is electrically connected with each electric-controlled parts.
Adopt after above structure, tool of the present invention has the following advantages: by the combination of the first gas-liquid separator, the first compressor, the second pressure fan, First Heat Exchanger, the second heat exchanger, device for drying and filtering, throttle part and cross valve, then in conjunction with the control of controller.The cooling dryer of described cereal has cooling and dries two kinds of functions of desinsection, in the time that needs are lowered the temperature to cereal heap, unit moves with refrigeration mode, by the ringing of refrigerant, make First Heat Exchanger that the heat absorption of the air in First Heat Exchanger chamber is made to air cooling-down, and by the first pressure fan, the air after cooling is sent into cereal heap from the first air outlet, air at room temperature in the middle of this process in warehouse can constantly enter First Heat Exchanger chamber from the first return air inlet, after heat exchange cooling, sent into by supporting airduct in cereal heap by heat exchanger, operational mode in this process in the second regenerator volume is identical with the pattern in First Heat Exchanger chamber, just the second heat exchanger is now carried warmed-up air through supporting airduct outside warehouse.In the time that needs are dried desinsection to cereal heap, unit moves with heating mode, by the ringing of refrigerant, make First Heat Exchanger make atmosphere temperature rising to the release of the air in First Heat Exchanger chamber, and by the first pressure fan, the air after heating up is sent into cereal heap from the first air outlet, air at room temperature in the middle of this process in warehouse can constantly enter First Heat Exchanger chamber from the first return air inlet, sent into by supporting airduct after heat exchange heats up by heat exchanger in cereal heap, operational mode in this process in the second regenerator volume is identical with the pattern in First Heat Exchanger chamber, just the second heat exchanger is now carried desuperheated air through supporting airduct outside warehouse, after being controlled at 50 degree left and right and maintaining a period of time, temperature can in the situation that not damaging cereal, kill the insect in cereal, and this temperature just can make being evaporated of water effective in cereal, can remove the moisture of cereal, prevent that cereal from becoming damp and rotten.
As preferably, in described casing, be provided with two working cells.Two working cell operating efficiencies are higher, can well tackle large-scale cereal heap.
As improvement, on the second described 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 in winter and use and dry insecticidal function, and the frost that the second heat exchanger produces during to outdoor eliminating cold wind, to ensure the stable operation in low temperature environment of whole machine.
As improvement, the bottom of described casing is provided with the roller for casing is moved freely.It is more convenient that roller structure moves machine.
