For the utility model, in order to more understand that ground understands the technical solution of the utility model, below to this practicality
New operation principle is illustrated.
When running for the first time, the first material inlet valve 9 and the second material inlet valve 11 are opened, material to be dried is passed through into feed hopper
In second conveyer 12 in 10 feeding drying boxes 8.Second conveyer 12 is run, and material to be dried is passed through into first
Air deflector 13 is imported in second conveyer 14.At this time, by adjusting charging rate and second conveyer 12 and second
The running speed of conveyer 14, can adjust spreading depth of the material on conveyer.When material to be dried is first
After being evenly distributed on conveyer 12 and second conveyer 14, stop charging, and close the biography of second conveyer 12 and second
Send device 14.Then, the first material inlet valve 9 is closed, the second discharge valve 18 of holding is closed mode, opens vavuum pump 22, beats
The first discharging opening 16, the first vacuum valve 20 and the second vacuum valve 21 are driven, the air in drying box 8 is discharged so that in drying box 8
In vacuum state；Then, the second material inlet valve 11, the first discharge valve 16, vavuum pump 22, the first vacuum valve 20 and the are closed
Two vacuum valves 21.Start compressor 1, after the refrigerant heat in compressor 1, formed HTHP refrigerant be delivered to it is cold
In condenser 2, and heat exchange is carried out with flowing through the outer loop air at the condenser 2 in condenser 2 so that refrigerant becomes
Into liquid, then, the refrigerant of liquid carries out throttling cooling at choke valve 3, continues through refrigerant tubing 5 and flow to evaporator

At condenser 2, the heat that circulation air discharges when the refrigerant in absorptive condenser 2 is condensed passes through after temperature rise
Air channel 7 enters in drying box 8, the material to be dried for drying, then, and circulation air is after evaporator 4 is flowed through, and by heat
Pass to the refrigerant of the low temperature liquid in evaporator 4, the temperature drop of circulation air, while the moisture inside circulation air
Condense and separate out.
After the completion of first dry materials, in order to change material, it is necessary to open the first discharging opening 16, start first and transmit
Device 12 and second conveyer 14, the material dried are concentrated in discharging by the first air deflector 13 and the second air deflector 15
Bucket 17, is then shut off the first discharging opening 16, opens the second discharging opening 18 and takes out material, and outside air can be avoided again and enters dry
In dry case 8, take out after dry material, close the second discharging opening 18.At the same time, first charging aperture 9 is opened by next group
Material to be dried add feed hopper 10, be then shut off first charging aperture 9.Vavuum pump 22 is opened, the He of the first vacuum valve 20 is opened
Second vacuum valve 21, the air in feed hopper 10 and discharge bucket 17 is discharged, and is maintained and the vacuum state in drying box 8, it is to avoid
The oxygen having in feed hopper 10 and discharge bucket 17 in air flows into and drying box 8 is had undesirable effect.Second is opened to feed
In second conveyer 12 in mouth 11, material feeding drying box 8.Second conveyer 12 is run, and material to be dried is led to
Cross the first air deflector 13 to import in second conveyer 14, hence into the drying process process of next group.
When the dry materials of last batch are to after presetting the moisture content needed, the first discharging opening 16 is opened, starts first
Conveyer 12 and second conveyer 14, the material dried are concentrated in by the first air deflector 13 and the second air deflector 15
Discharge bucket 17, is then shut off the first discharging opening 16, opens the second discharging opening 18 and takes out material, is then turned off the second discharging opening
18.Therefore, the drying process operation to the material of whole batches is realized.
It should be noted that for the utility model, terminating until the material of all batches is all dry, Analysis of Heat Pump Drying System
All the time work, to maintain it internal with higher drying air temperature and relatively low humidity, and vacuum system is then simply in heat
Start during vacuum degree deficiency in pump drying system.
In summary, compared with prior art, a kind of continuous type heat pump vacuum that the utility model is provided is done
Dry machine, it can be while realizing to multiple batches of material progress continuous drying processing, it is ensured that during material is changed,
Avoid causing unnecessary energy resource consumption and thermal loss, at the same avoid the oxygen being rich in extraneous air directly with drying box
Material to be dried come in contact, reduce occur oxidation reaction, so as to ensure the nutrient composition content inside material, favorably
In widely popularization and application, it is of great practical significance.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as protection domain of the present utility model.
