One end connection of heat pump 1, the other end of heat pump is connected with microwave cavity 7 bottom by discharge pipe 4, is opening heat-pump dehumidification mould
During formula, the thermal cycle of hot blast, more effective dried material can be realized.It is respectively arranged with automatic vacuum on backwind tube 2 and discharge pipe 4
Isolating valve 3, the unlatching of automatic vacuum isolating valve and Guan Bi can realize microwave vacuum heating and heat-pump dehumidification two kinds of drying modes
Effectively freely change.Self-draining arrangement 13 it is provided with, when the water produced after microwave vacuum drying can be bottom microwave cavity 7
Automatically flow out after opening self-draining arrangement, be not required to manually dehumidify.Microwave cavity 7 is additionally provided with the vacuum pump of external vacuum source and connects
Mouth 9.
The technical scheme that this utility model limits further is:
Further, microwave cavity 7 is installed in frame 14, makes the work that microwave cavity is stable, is moved easily.
Further, microwave cavity 7 is outside is provided with door 12.
Further, microwave tube 6 is powered by microwave power supply case 5.
The beneficial effects of the utility model are: utilize the advantage of each self-desiccation of microwave, vacuum, heat pump to carry out combined drying,
Have following features: 1) after microwave vacuum drying terminates, carry out heat-pump dehumidification can rapidly remove material surface moisture, overcome
Air-flow does not flows under vacuo, and moisture is difficult to the difficult problem removed.2) on heat pump backwind tube, automatic vacuum isolating valve it is provided with, can
