To desiccation.As in figure 2 it is shown, the branched pipe 6 on central canal 4 is uniformly distributed along central canal 4 length direction, and along center
The circumferencial direction of pipe 4 then main integrated distribution is on the periphery that central canal 4 bottom is relative with cylinder 3 bottoms material.In second
Branched pipe 6 on heart pipe 5 is also same distribution.Such as Fig. 3, it is shown that central canal 4 and the side view of branched pipe 6, from side view
Seeing, branched pipe 6 is sector distribution in the bottom of central canal 4, and so, the dry gas in central canal 4 can lead in branched pipe 6
Cross different directions to be injected on the material bottom cylinder 3 so that material can sufficiently come in contact with dry gas, thus
To dried.In like manner, the second central canal 5 is also the same with the side view of branched pipe 6 thereon.
In the present embodiment, cylinder 3 bottom is provided with the first hot-air system 13 and the second hot-air system 12, the first hot-air system
The temperature of the 13 dry gases controlling the central canal 4 in the first dry section A1 and flow.It is dry that second hot-air system 12 controls second
The temperature of the dry gas of the second central canal 5 in dry district A2 and flow.Such as: when needing being in the first dry section A1
When material carries out the drying and processing of high temperature, described first hot-air system 13 can doing the central canal 4 in the first dry section A1
Dryness body is heated to preset temperature, when reaching preset temperature, stops the heating to dry gas.Same, when needs are to being in
When material in second dry section A2 carries out the drying and processing of low temperature, described second hot-air system 12 can be to the second dry section A2
The dry gas of the second interior central canal 5 is heated to preset temperature, when reaching this preset temperature, stops adding dry gas
Heat.Utilize two different dry sections that material carries out the dried of different temperatures, make the material moisture flowed out from dry section A
Reach technological requirement, also provide process conditions for follow-up cooling moisture regain.
Described moisture discharge device includes the first moisture discharge device 2 and the second moisture discharge device 7, and cylinder 3 front end is provided with the first humidity discharging
Device 2, it is outside that the moisture after being dried by material in the first dry section A1 discharges cylinder 3.Second dry section A2 and cooling
Being provided with the second moisture discharge device 7 between district B, it is outside that the moisture after being dried by material in the second dry section A2 discharges cylinder 3.
In the present embodiment, the humidity discharging of the first moisture discharge device 2 and the second moisture discharge device 7 can use suitable, adverse current switching or work simultaneously.
In the present embodiment, being provided with outer percolation ventilating system 8 in the B of cooling zone, this outer percolation ventilating system 8 has for inside
The screen drum of mesh structure, for dry gas relatively low for temperature through described screen drum and is applied to material from cylinder 3 outside,
Make temperature of charge be reduced to standard temperature, thus provide process conditions for follow-up material moisture regain.It is provided with rake in moisture regain district C
Pin structure and humidification system 9, described humidification system 9 includes steam nozzle.Utilize steam nozzle uniformly to spray water on material, make thing
Material reaches the moisture of technological requirement, thus realizes the purpose of uniformly moisture regain.
In order to make, the material bottom cylinder 3 is more stable to slide towards cylinder 3 discharge end 10 glibly.In the present embodiment, a side
Face, is obliquely installed cylinder 3 and central canal 4 towards discharge end 10 direction.Preferably, cylinder 3 and central canal 4 axial line and horizontal line
Become 0 °～10 ° of angles.On the other hand, the branched pipe 6 on described central canal 4 becomes 70 °～90 ° of angles with central canal 4, and described second
Branched pipe 6 on central canal 5 becomes 70 °～90 ° of angles with the second central canal 5.From the dry gas of branched pipe 6 discharge to cylinder 3
The material of bottom provides an active force towards discharge end 10 direction so that material slides inside cylinder 3 glibly.This cylinder
Body 3 is obliquely installed and angle appropriate between central canal 4 and branched pipe 6 is arranged, and both can guarantee that the slip that material is smooth, and again could
Ensure that the speed that material slides is unlikely to too fast.Material, again can be steady by while abundant moisture regain dry, sufficiently cool and uniform
Ground is discharged from discharge end 10.
In the present embodiment, also include that driving means 14, described driving means 14 drive cylinder 3 to rotate around cylinder 3 axial line.
When cylinder 3 rotates, central canal the 4, second central canal 5 and branched pipe 6 do not rotate with cylinder 3.Cylinder 3 turns around the axial line of cylinder 3
Kinetic energy enough makes Nicotiana tabacum L. sufficiently contact with the dry gas stream ejected from branched pipe 6, and drying effect becomes apparent from.
In the present embodiment, the work process of burley tobaccos dehydrator is as follows:
Need material is dried, get damp again process time, start dehydrator, cylinder 3 starts to rotate.Managing and control system 15 controls
Blower fan and heat exchanger are operated, and carry out heat exchange to obtain being dried gas (such as: hot blast or superheated steam) with air.Wind
Dry gas is delivered to discharge end 10 by machine, is dried gas and respectively enters central canal 4 He from the dry gas access of discharge end 10
In second central canal 5.When the temperature in the second central canal 5 reaches preset temperature, managing and control system 15 controls material from feed end 1
Entering cylinder 3 internal, material, due to the effect of self gravitation, is in bottom cylinder 3 all the time, owing to cylinder 3 rotates, material along with
Cylinder 3 rotates and rolling agitation occurs, thus completely attaches to the dry gas discharged from branched pipe 6 so that material is filled
The dried divided.First the material entered from feed end 1 contacts with the high-temperature dry air discharged from central canal 4 and is done
Dry process, then contacts with the cold drying gas discharged from the second central canal 5 and obtains further dried, due to the
Temperature in two central canals 5 is less than the temperature in central canal 4 so that after the dry gas contact in material and the second central canal 5
Temperature reduces, and prepares for follow-up cooling.In the dry run carrying out material, the flow direction phase of dry gas stream and material
Instead, the dry gas velocity maximum that the branched pipe 6 of feed end 1 is discharged more it is proximate to.The dry gas discharged from branched pipe 6 and cylinder
Tobacco bottom body 3 is fully contacted, and material, in dry run, occurs a series of chemical reaction, along with drying time
Increase, the moisture in material is gradually evaporated, the moisture with miscellaneous QI evaporated pass through the first moisture discharge device 2 and second row
Tide device 7 discharges cylinder 3.In dry section A fully dried, Flow of Goods and Materials to cooling zone B, worn by outer in the B of cooling zone
It is the most air-cooled that circulation wind system 8 carries out outer flow-through type to the material bottom cylinder 3, enters back into moisture regain district C afterwards, at moisture regain district C
Discharged outside cylinder 3 by discharge end 10 again after interior uniformly moisture regain.
In the present embodiment, as shown in Figures 4 to 6, the end of the on-fixed end of described branched pipe 6 is provided with the spray of dry gas
Mouthful, the bore of described dry gas spout is not more than the caliber of branched pipe 6；Described dry gas spout be shaped as duckbill or
Person is conical or cylindrical.So, it is ensured that be dried gas towards the direction ejection specified and the speed improving dry gas ejection.
The above is only presently preferred embodiments of the present invention, and the present invention not makees any pro forma restriction, though
So the present invention is disclosed above with preferred embodiment, but is not limited to the present invention, any technology people being familiar with this patent
