Abstract
The invention discloses a low flow speed steam nozzle for tobacco processing, which comprises a steam pipeline (1), wherein the steam pipeline (1) is connected with a straight cylinder type nozzle (2) of which the diameter is multiple times larger than that of the steam pipeline (1); and the outer layer of an outlet of the straight cylinder type nozzle (2) is provided with a second level mesh choke plate (4), the inner layer thereof is provided with a first level mesh choke plate (3), the aperture of meshes on the first level mesh choke plate (3) is larger than that of the meshes on the second level mesh choke plate (4), and the number of the meshes on the second level mesh choke plate (4) is more than that of the meshes on the first level mesh choke plate (3). The low flow speed steam nozzle for tobacco processing can achieve loosening and dampening precision processing of tobacco flakes in a common loosening and dampening machine, can effectively improve the stability and evenness of the loosening and dampening precision processing of the tobacco flakes, and achieve the fine processing of tobacco leaves; besides, the low flow speed steam nozzle has the advantages of simple structure, convenient manufacture and reliable performance.
Description
Technical field
The present invention relates to the processing unit (plant) that grows tobacco, particularly relate to and a kind ofly in tobacco flake remoistening, reinforced process, smoked sheet is carried out the tobacco low-flow speed steam nozzle for processing that steam accuracy, uniformity apply.
Background technology
Tobacco flake remoistening, the reinforced processing are requisite links in the cigarette process, and its treatment effect is bigger to cigarette product aesthetic quality's influence, and main cause is that the heat in the passive absorption steam of smoked sheet changes tobacco components.Stability, uniformity and controllability that raising steam applies are difficult problems that needs to be resolved hurrily in the industry.The smoked sheet material obtains the opportunity of passive heating in the current process in equipment unequal, original device exists and causes in the process part smoked sheet to be blown into the less smoked sheet that causes of equipment discharge end, radiating surface by moment accepting obstacles such as steam thermal energy is inconsistent because of steam flow rate is too fast, make the variation of tobacco components in being subjected to thermal process can not get effective control, simultaneously, there is the relatively poor problem of uniformity in tradition processing.
Therefore, tobacco leaf obtains heat by hot conductive form and improves temperature in the loosening and gaining moisture process, and setting up a vapour field stable, wide coverage in inner barrel is the key that improves processing uniformity, stability.
Summary of the invention
Technical problem to be solved by this invention provides a kind of tobacco low-flow speed steam nozzle for processing of realizing the processing of tobacco flake remoistening accuracy in common loosening and gaining moisture machine.
In order to solve the problems of the technologies described above, tobacco low-flow speed steam nozzle for processing provided by the invention, comprise jet chimney, on described jet chimney, be connected with the straight barrel type nozzle of its diameter greater than described jet chimney diameter several times, skin in the outlet of described straight barrel type nozzle is provided with secondary mesh-type spoiler, internal layer is provided with one-level mesh-type spoiler, mesh aperture on the described one-level mesh-type spoiler is greater than the mesh aperture on the described secondary mesh-type spoiler, and the mesh quantity on the described secondary mesh-type spoiler is greater than the mesh quantity on the described one-level mesh-type spoiler.
Mesh on mesh on the described one-level mesh-type spoiler and the described secondary mesh-type spoiler all adopts tapered mesh.
Adopt the tobacco low-flow speed steam nozzle for processing of technique scheme, caliber changes and the principle of speed change when utilizing gas to flow in pipeline, nozzle adopts the straight barrel type nozzle, and its diameter is greater than jet chimney diameter several times, and speed moment reduces when making steam enter nozzle; Design on the one-level mesh-type spoiler and secondary mesh-type spoiler at jet expansion simultaneously, its mesh adopts tapered mesh, makes the vapor stream speed that ejects low, and diffusingsurface is big.Can make the thermal vapor stream zone that speed of the interior formation of tube is small and weak, have a wide reach.In conjunction with steam consumption being implemented control, and then make the inner barrel gas flow temperature keep a required stable state of tobacco processing.The application of this device will the device interior front end form relatively-stationary between a steam radiation area, temperature is metastable, cover the hot vapour field of whole cylindrical shell cross section, make the smoked sheet material in equipment, obtain the opportunity equalization of passive heating in the current process, having overcome original device causes in the process part smoked sheet to be blown into the less smoked sheet that causes of equipment discharge end, radiating surface by moment accepting obstacles such as steam thermal energy is inconsistent, the variation of tobacco components in being subjected to thermal process is effectively controlled because of steam flow rate is too fast.Simultaneously, solved the relatively poor problem of traditional processing uniformity.
In sum, the present invention is a kind of tobacco low-flow speed steam nozzle for processing of realizing the processing of tobacco flake remoistening accuracy in common loosening and gaining moisture machine, can effectively improve the stability, uniformity that tobacco flake remoistening is handled, realization is to the processing that becomes more meticulous of tobacco leaf, simple in structure, easily manufactured, dependable performance.

The specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, Fig. 2 and Fig. 3, on jet chimney 1, be connected with the straight barrel type nozzle 2 of its diameter greater than jet chimney 1 diameter several times, skin in the outlet of straight barrel type nozzle 2 is provided with secondary mesh-type spoiler 4, internal layer is provided with one-level mesh-type spoiler 3, mesh aperture on the one-level mesh-type spoiler 3 is greater than the mesh aperture on the secondary mesh-type spoiler 4, mesh quantity on the secondary mesh-type spoiler 4 is greater than the mesh quantity on the one-level mesh-type spoiler 3, and the mesh on mesh on the one-level mesh-type spoiler 3 and the secondary mesh-type spoiler 4 all adopts tapered mesh 5.
Referring to Fig. 1, Fig. 2 and Fig. 3, the application of this device will the device interior front end form relatively-stationary between a steam radiation area, temperature is metastable, cover the hot vapour field of whole cylindrical shell cross section, make the smoked sheet material in equipment, obtain the opportunity equalization of passive heating in the current process, having overcome original device causes in the process part smoked sheet to be blown into the less smoked sheet that causes of equipment discharge end, radiating surface by moment accepting obstacles such as steam thermal energy is inconsistent, the variation of tobacco components in being subjected to thermal process is effectively controlled because of steam flow rate is too fast.Simultaneously, solved the relatively poor problem of traditional processing uniformity.
Referring to Fig. 1, Fig. 2 and Fig. 3, adopt the loosening and gaining moisture device of technique scheme, in implementing tobacco processing course, the 1st step: according to raw tobacco material separately processing characteristics set corresponding steam applied amount, hot blast wind-warm syndrome T2, hot blast air quantity N, humidity discharging aperture M, start preheating, reach the preheat temperature requirement fast; Treat that an interior temperature reaches setting and requires steam off, and time-delay control is treated can put into production after the cylinder inboard wall drying.The 2nd step: drop into leaf tobacco production, follow the tracks of and enable steam.Bigger variation takes place in temperature of charge T1 in the process, and appearance is serious on the low side or seriously higher, then revises steam consumption D fast and follows the tracks of adjustment humidity discharging aperture M; If slight fluctuations occurs, then suitably adjust humidity discharging aperture M, make an interior temperature T 3 reach the requirement of product machined parameters.
