Abstract
The utility model relates to a microwave disposing equipment in the continuously expanding drying tobacco shred system with a high temperature pipe type. A plurality of microwave units is combined to a microwave disposing equipment corresponding to the shape and the size of the original system expansion joint between the venturi tube of tobacco shred inlet and the cyclone separator of the system. Each microwave comprises a microwave source, a wave guide of surface wave, a loading, a wave guide groove clearance and a ridge. The inner moisture formed in the pre disposing process and in the expansion joint which is higher than the outside moisture dumpling tobacco shred passes the microwave field, the moisture of the dumpling tobacco shred is dried by the microwave, reaching the exact adjusting and controlling to the tobacco shred moisture.
Description
Technical field: the utility model relates to the preparation of tobacco, the microwave heating appts in the continuous expansion drying pipe tobacco of the particularly a kind of high-temperature pipe formula system.
Background technology: application number be 92104082.2 by British American Tobacco in Chinese patents, disclose a kind of in high-temperature pipe the method and apparatus of continuous drying expanded cut tobacco.This be a kind of a pipeline high speed by high-temperature hot air and high-temperature vapor, and pipe tobacco is mixed in this pipeline with high-temperature hot air and high-temperature vapour and dry, the drying means that separates through cyclone separator also has many other patents simultaneously then.Such as hot junction with dry-ice expanding tobacco device system.These methods all make pipe tobacco fully mix in pipeline with high hot-air and high heat steam, and drying is common feature very fast, also are so-called impingement drying.The filling power of pipe tobacco in this drying mode is more higher than alternate manners such as drum-types, and quality also improves.It is method and apparatus the most advanced in the present technology for making tobacco threds.But, in the actual use of China, still have many problems to fail to solve, as the damage to tobacco shred intrinsic fragrance that high temperature causes, in pre-treatment and the dry run " pipe tobacco conglomeration ", the conglomeration moisture in cut tobacco is not up to standard, do not expand, and can not be used, cause waste by the postorder cigarette.Because its dry rapidity and system thermal inertia own are very big, cause the outlet moisture in cut tobacco long period of waves, local moisture imbalance or the like.
Summary of the invention: the purpose of this utility model is at system outlet pipe tobacco conglomeration of high-temperature pipe formula tobacco shreds drying and moisture in cut tobacco long problem period of waves, between this system's pipe tobacco import Venturi tube and cyclone separator, constitute microwave heating appts, and make it consistent with the shape and size of the expansion joint (dryer section) of original system by a plurality of microwave unit permutation and combination; The microwave unit of power supply control is made up of microwave source, surface wave guide, ridge, load and the waveguide line of rabbet joint, and the waveguide slot of microwave unit chamber wall is sewed on and is provided with removable interlayer.
The utlity model has following advantage:
1. form microwave field at expansion joint (dryer section) internal chamber wall, and the power density of microwave field is successively decreased to the center, chamber by the chamber wall.To heat the conglomeration pipe tobacco that rolls across the chamber wall emphatically like this, work and misalign heart place.
2. some surface wave trapezoidal waveguides of forming microwave field can make up according to the needs of expansion joint (dryer section) size, also can arrange the combination of density combination and watt level according to " conglomeration " reason in this section of testing.
On the microwave cavity wall as the microwave low-loss materials of interlayer, when having tar to adhere to, can change.
4. it is short that system's thermal inertia is little, moisture is regulated period of waves, makes system have advantages of higher stability and controlled.
5. in the microwave drying of expansion section and cyclone separator upper area to " conglomeration pipe tobacco ", make its dry atmosphere of expanding of keeping, do not influence its expansion rate.

According to accompanying drawing utility model is described further below:
Specific embodiment: as shown in Figure 1, a kind of microwave heating appts of continuous tobacco expanding drying.Between pipe tobacco import 1 and pipe tobacco outlet 13, form and expansion joint 2, the consistent microwave heating appts of cyclone separator 4 internal chamber wall shape and size; Shown in Fig. 2,3, this microwave heating appts is by surface wave guide 8, microwave source 7, the power supply of a plurality of microwave units 5 and control 6, load 10 forms; Shown in Fig. 4,5, in the surface wave trapezoidal waveguide of microwave unit ridge 9 is arranged, the surface wave guide fluting face and the line of rabbet joint 11 are located on the internal chamber wall of expansion joint 2 and cyclone separator 4, also be provided with the interlayer 12 of removable low-loss material on the chamber wall of surface wave guide face 8, and structures such as the cooling that needs on the engineering, insulation, heat radiation, installation form, and its load is used to consume remaining power.Its operation principle and concrete technical descriptioon are as follows: after pipe tobacco was handled through moisture regain, by pipe tobacco import 1, enter in the dryer section of being made up of microwave device and expansion joint 2, high hot blast and high heat steam mixed with pipe tobacco through the hot blast steam-gas inlet.Microwave source 7 by power supply 6 control microwave units 5, through surface wave guide 8, ridge 9, form microwave field at surface wave conducting surface (face of promptly slotting), and produce a microwave field that successively decreases to the center power density by the microwave cavity wall, also promptly forming the microwave field that power density is stronger near wall place, chamber.And the surface wave line of rabbet joint is isolated by interlayer 12 that pastes microwave low-loss materials thereon and hot blast pipe tobacco.Because in the hot blast pipe tobacco mixed process, " the conglomeration pipe tobacco " that various reasons forms will be dried during through this microwave field in pre-treatment process neutralization, and the pipe tobacco that is dried can conglomeration, and can not influence the expansion rate of pipe tobacco in the microwave drying of expansion area.
