2, the drying machine of the overwhelming majority is that cost is higher taking fuel oil as thermal source substantially;
3, there is the problem that drying efficiency is low, energy consumption is high, the batch processed cycle is long in existing grain drier;
4, grain drier life cycle is short, and annual approximately 50 days drying times that use, utilization rate is low.
Utility model content
In order to overcome above-mentioned technical problem, the double-effect heat pump rice drying system that provides a kind of utilization rate high is provided the purpose of this utility model, can also be freezer refrigerating in dry.
The technical scheme that the utility model adopts is:
A kind of double-effect heat pump rice drying system, comprise drying machine, source pump and freezer, the hot-blast outlet of described source pump connects the hot-wind inlet of drying machine by pipeline, described source pump comprises dehumidifying evaporimeter, water evaporimeter and condenser, described dehumidifying evaporimeter and the water evaporimeter condenser that is connected in parallel, in described freezer, be provided with evaporimeter in storehouse, in described storehouse, evaporimeter connects water evaporimeter by circulation waterway.
As the further improvement of technique scheme, the supporting dehumidifying magnetic valve of controlling refrigerant turnover that is provided with of described dehumidifying evaporimeter cuts out dehumidifying magnetic valve in the time being only required to be freezer refrigerating.
As the further improvement of technique scheme, described water evaporimeter is supporting is provided with the cooling magnetic valve of controlling refrigerant turnover, when only needing to close cooling magnetic valve while carrying out paddy dehumidifying.
And cooling magnetic valve and dehumidifying magnetic valve while opening simultaneously system rice drying and freezer refrigerating carry out simultaneously.
As the further improvement of technique scheme, described circulation waterway is provided with water pump and the water storage tank of series connection, and frozen water is stored in water storage tank, stocks for freezer provides sufficient cold, makes the temperature constant of freezer.
As the further improvement of technique scheme, in described water storage tank, be provided with water thermometer, described water thermometer signal is connected with water temperature controller.
As the further improvement of technique scheme, in described freezer, be provided with hygrosensor and freezer electric cabinet, in described freezer electric cabinet, install and be provided with the temperature of ice house controller being connected with hygrosensor signal.
The principle of this heat pump rice drying system is as follows:
System is first draw heat from the air by dehumidifying evaporimeter of the refrigerant in source pump in the time being dried separately, and the temperature of air is quickly fallen to below dew point, and at this moment the moisture condensation of air is separated out (water of separating out is discharged), and now refrigerant temperature raises; Then, condenser draw heat from refrigerant is used for heating by dewatered air, atmosphere temperature rising and relative humidity are significantly declined, become and carry wet very capable dry air, dry air enters drying machine, then, equably by paddy to be dried, takes away moisture in paddy, constantly circulation in drying machine of paddy, paddy thereby be dried.Carry out constantly when dry and refrigeration, refrigerant is by water evaporimeter simultaneously, and refrigerant is drawn the heat in water, thereby the temperature of water is reduced, and the water after cooling flows through evaporimeter in storehouse and carries out heat exchange, reduces the temperature in freezer, realizes the fresh-keeping and storing of agricultural product; Refrigerant is realized drying operation through dehumidifying evaporimeter and condenser simultaneously.In the time that independent example is used freezer, refrigerant only passes through water evaporimeter and condenser, the water of circulation waterway is carried out cooling, for freezer provides cold.
The beneficial effects of the utility model are: the utility model has been introduced water evaporimeter in source pump, this water evaporimeter connects the storehouse evaporimeter that is positioned at freezer by circulation waterway, making system can be also freezer refrigerating in dry paddy, reach the object of economic benefits and social benefits, thereby save the extra refrigeration energy, reduced energy consumption and cost.
