10. blade 11. supporting legs 12. inlet tubes

(13. transfer plate) through hole

Below in conjunction with accompanying drawing embodiment of the present utility model is further described.With reference to Fig. 1, it is by microwave cavity 1, and chain transmits net row 2, dense block 3, and discharge duct 4 grades are formed an active section (unit).One or several active sections (unit) are end to end has just formed the equipment that complete being used to dried or heated.

The power of this machine is motor, and heating power is microwave generator, and its control circuit is a prior art.

Microwave cavity 1 is the heater block of active section, and internal arrangement the magnetron of some, by launched microwave, provides heat energy.The quantity of configuration magnetron is by active section job specification of living in and need add the heat decision.

Chain transmits net row 2 to be made up of shell 5, transmission chain 6, track 7, transfer plate 8 etc., and it is moving not stop transport under reductor drives, and bears tobacco and carries task.Transfer plate 8 has two kinds of principal modes, and is with holes and not with holes.Transfer plate 8 with holes is mainly used in cooling section and oven dry section, and transfer plate 8 not with holes is mainly used in bringing-up section, soaking zone and moisture regain section.

Dense block 3 is mainly by housing 9, and blade 10 is formed.Blade 10 does not stop rotation in housing 9 under reductor drives.It mainly acts on: 1. loose tobacco.Tobacco is every just can to obtain once inside out and loose through a dense block 3, so that better got damp again or drying effect; 2. organize every microwave, prevent that microwave from outwards or to neighbour's active section leaking; 3. organize every air, make each active section obtain independently ventilated environment.

Discharge duct 4 provides negative pressure to each active section, combustion gas under the blower fan effect of (accompanying drawing does not show).On discharge duct 4, volume adjusting apparatus is installed, to control the ventilation of each active section.Oven dry section and cooling section need provide big ventilation to discharge hot-air and the humid air in the active section.Bringing-up section, soaking zone and moisture regain section only need to keep a negative pressure in active section, make that damp-heat air is unlikely to escape.

Different active sections adopts different intake methods, and bringing-up section, soaking zone and moisture regain section can not established air inlet pipeline.Cooling section can directly air inlet from air.The oven dry section can utilize the hot-air that the magnetron heat radiation is obtained to carry out air feed.

The critical piece of each active section is essentially identical, and heating power configuration, draft type, transfer plate form have determined the effect of active section: bringing-up section disposes a fairly large number of magnetron, adopts transfer plate not with holes to form the draft type of no air inlet.The moisture regain section is that with the difference of bringing-up section tobacco added atomized water before entering bringing-up section.The difference of soaking zone and bringing-up section is to dispose the negligible amounts of magnetron.The a spot of magnetron of oven dry section configuration to replenish the thermal loss of tobacco, adopts transfer plate form with holes, needs bigger ventilation.Cooling section need not dispose magnetron, adopts transfer plate form with holes, needs bigger ventilation.

A typical drying plant is combination like this: bringing-up section+oven dry section+cooling section.A typical moisture regain equipment is combination like this: moisture regain section+soaking zone.According to the actual conditions needs, can increase the progression of a certain active section, as secondary heating, secondary moisture regain, also can make an active section play two active sections.As strengthen the power configuration of drying section, just formed the heating, drying section.Tobacco is through heating, dried, cool off, reached the purpose of removing excessive moisture in the tobacco in drying plant.In moisture regain equipment, tobacco has reached the raising moisture content through moisture regain, insulation, improves the purpose of temperature.Drying plant and moisture regain equipment also can be combined in together, form oven dry one moisture regain equipment, and according to the production capacity difference, oven dry or moisture regain equipment can be made into the series of products of different length, width.
