Fig. 2 is internal structure schematic diagram of the present invention;
Specific implementation mode
In conjunction with description of the drawings, the present invention is further described with embodiment:
Such as Fig. 1 and Fig. 2, a kind of efficient dehumidification type heat pump drying unit, including body 1;Wherein:The internal body difference It is provided with hothouse 2, compressor 3, condenser 4, evaporator (51,52), heat regenerator 6, liquid storage device 7, electric expansion valve 8, row Wet blower 9 and breeze fan 10;2 front end of the hothouse is equipped with return air inlet 11, and hothouse rear end is equipped with air outlet 12;It is described dry Dry room 2 is internally provided with multiple layer tray 13;9 one end of the wet-emitting blower is connected with moisture exhausting port 14;The connection storage of the moisture exhausting port 14 Liquid device 7;The breeze fan 10 connects air outlet 12;The evaporator includes the first evaporator 51 and the second evaporator 52.Two A evaporator reaches optimum Working, maximum dehydrating amount in different operating mode adjust automaticallies;Outside air is absorbed using evaporator In heat source or recycling drying process in the waste heat that is vented product is dried, reach energy-efficient purpose, and heat pump drying The working efficiency of unit is not influenced by area and season.
A plurality of parallel air paths 15, gas channel 16 are additionally provided in the body 1;The parallel air paths 15 are by multigroup wind-guiding Board group is at the wind deflector is mounted in body 1, the side of the gas channel setting wind deflector;The gas channel 16 divides It Lian Jie not air outlet and parallel air paths.Parallel air paths are set, and air duct is short, and uniform drying is consistent;Body is closed loop drying structure, energy Amount is not scattered and disappeared externally.
The wet-emitting blower 9 and breeze fan 10 are all type strong wind type wind wind turbine.High wind without dead angle convection current, it is not necessary that stir can be equal Even drying;Quickly removal surface moisture film, allows mould without life condition.
Strong magnetic absorbing door 17 is additionally provided on the body 1;The strong magnetic absorbing door 17 is closed by magnetic mode, two stainless steels Door is directly attracted without lock, easy to use, non-maintaining.
The electric expansion valve 8 is connected with temperature sensor and humidity sensor.It is controlled, is allowed by electric expansion valve precision System is in optimum Working always.
The pallet 13 is PP food grade plastic pallets.It directly stacks, is efficiently convenient;Cancel shelf, not only saved cost but also Save space;It can at most place that 40 pallets, to pave area big.
The engine body exterior is equipped with control panel 18;The control panel is equipped with graph image control interface, visualization Operation is convenient for the use of user, reduces the difficulty of operation, be conducive to the promotion and application of heat pump drying unit;Without outer Enclose accessory;Power supply need to be only connected to can be used;It is general, practical using single-phase electricity.
The compressor 3, wet-emitting blower 9 and breeze fan 10 are connected separately with muffler.It is dry that muffler reduces heat pump The noise generated in the dry unit course of work, provides good working environment.
The operation principle of the present invention:When work, the product dried according to different need by control panel sets drying Time and other drying parameters, compressor compress air, and the hot-air by condenser heating is by breeze fan from air-supply Mouth feeding hothouse, hothouse are equipped with parallel air paths;Uniform drying is consistent, high wind without dead angle convection current, be not necessarily to turning over materials Evenly drying;Quickly removal surface moisture film, allows mould without life condition;Material in hothouse carries out damp and hot after damp and hot exchange Air returns to gas channel by return air inlet, and when requiring to need dehumidifying according to drying control, the wet of return air inlet is discharged to from hothouse Hot-air after damp-heat air is by heat regenerator recovery waste heat, then is mixed with damp-heat air, and air is carried out by condenser after mixing Heating, the air after heating are fed again into hothouse by breeze fan.Material in hothouse exchanged heat after damp and hot sky Steam is discharged into liquid storage device through moisture exhausting port by wet-emitting blower after gas and recovery waste heat.When heat pump drying unit is stopped When make electric expansion valve fully closed, prevent condenser high-temp liquid flow into evaporator, energy loss when causing to be again started up.It opens Before machine, by electric expansion valve standard-sized sheet, so that system high and low pressure side is balanced, be then switched on.Light-load starting is not only realized in this way, but also is reduced Heat loss in shutting down.In addition, can shorten freeze-off time using electric expansion valve, electric expansion valve is in freezing overall process It can accomplish load and cold balancing, freezing efficiency can be improved, and freeze-off time can also shorten 10% than heating power expansion valve, together When also just reduce the energy consumption of compressor.It can be prevented because of delivery temperature using electronic expansion valve controls compressor exhaust temperature The adverse effect generated to system performance is increased, while ad hoc protector can be saved again, it is cost-effective, save power consumption.
In conclusion after those skilled in the art read file of the present invention, according to the technique and scheme of the present invention with Technical concept is not necessarily to creative mental labour and makes other various corresponding conversion schemes, belongs to the model that the present invention is protected It encloses.
