Description
Technical field
The utility model belongs to tobacco processing unit (plant) technical field, specifically, being related to a kind of multiple suitable for smoked sheet roller
Air-distribution device in roasting cylinder.
Background technique
Piece cigarette redrying is very important process in tobacco preliminary working technique, and the quality of piece cigarette redrying is special to the physics of blade
Property and organoleptic attribute have large effect.Currently, beating and double roasting enterprise generallys use net belt type tobacco redryer, with to spreading
Heated drying mode carries out piece cigarette redrying processing.It makes rear blade conveyer to be uniformly transported on redrying mesh belt, on foraminous conveyer
Certain thickness blade layer is formed, dryer section, cooling section and the resurgence section for then passing sequentially through tobacco redryer carry out at technique
Reason.
In existing net belt type redrying technique, blade redrying link is more, long flow path, and energy consumption is larger, while dry redrying
It needs in the process piece cigarette is over-drying to critical moisture content hereinafter, leading to that smoked sheet multiple roasting processing intensity is big, influences high-grade raw material
Organoleptic quality.Based on this, the smoked sheet multiple roasting technique of drum-type and device are increasingly led by tobacco processing procedure technology in recent years
Pay close attention to (ZL201210089215.6 in domain；The size changes in distribution feature of roller redrying mode bottom sheet cigarette, tobacco science and technology, 2016
(3): 84-90).Under roller redrying mode, target of the smoked sheet directly from initial aqueous rate drying and dehydrating to 11-13% is aqueous
Rate without cooling, the resurgence processing in traditional redrying technique, thus can simplify redrying technique, reduce the over-drying energy consumption of smoked sheet
And dry processing intensity.
For smoked sheet multiple roasting process, uniformity meeting of the dry-heat air in roller medium temperature moisture condition and air volume adjustment
Significantly affect the uniform drying of smoked sheet in cylinder.Roller redrying device is usually respectively equipped with air-heater in inlet port and outlet port
And moisture-eliminating blower.During roller drying, when high-temperature hot-air blows over material, it is right simultaneously that caloic occurs between material and hot wind
Stream transmitting, hot wind continual will take away the moisture in wet stock before reaching its saturated humidity, realize the dry of material
It is dry.In the drying process, the wet component of gasification rate and material inside of hot blast temperature and air quantity meeting extreme influence wet stock surface
Diffusion rate.Cloth wind mode in existing drum dryer is usually to be passed directly into heat via ventilation terminal in roller one end
Wind, hot wind are directly entered inner barrel through aperture on ventilation terminal, flow with material cocurrent or countercurrent, and this cloth wind mode leads to heat
Wind distribution randomness in roller is excessive, and hot wind contacts unevenly with material, and mass transport process is adversely effected, and drying efficiency is significantly
It reduces, meanwhile, this cloth wind mode makes the hot wind of outlet end contain a large amount of steam, and hot blast temperature, moisture distribution are uneven in cylinder,
The drying effect of drier end materials is very poor, affects smoked sheet multiple roasting drying effect.

Hot wind wind-distributing pipe both ends are connected with the exhaust outlet for being located at the hot wind inlet of roller feed end, being located at roller discharge end respectively, heat
Segmentation is evenly equipped with aperture on wind wind-distributing pipe tube wall.
The hot wind wind-distributing pipe diameter is 100 ~ 300mm；Hot wind wind-distributing pipe is divided into three sections of laying apertures, and cloth wind aperture is straight
Diameter is 8 ~ 20mm, and every segment length is the 1/3 of cylinder, and each section of upper percent opening is identical, from roller feed end to discharge end percent opening
Successively rise, since feed end, first segment wind-distributing pipe percent opening is 20% ~ 30%, and second segment percent opening is 25 ~ 35%, third section
Percent opening is 30% ~ 40%.Roller is tilting installation, and hot wind wind-distributing pipe is also tilting installation, and tilt angle and roller are kept
Unanimously.
More specifically, air-distribution device in the cylinder of the utility model, roller both ends inner wall is fixed with bracket, bracket and cloth wind
Pipe junction is equipped with bearing, to stablize wind-distributing pipe and rotate it with roller, further hot wind is kept to be evenly distributed.
Air-distribution device in the cylinder of the utility model, hot wind wind-distributing pipe both ends are connected with hot wind into, exhaust outlet respectively, wind-distributing pipe
Even tube wall is provided with aperture for heat air delivery, makes to be evenly distributed along cylinder axial direction hot blast temperature, may advantageously facilitate drying process
Progress, accelerate drying efficiency, so that dry materials effect in cylinder is reached unanimity.
The utility model has the following beneficial effects: being changed original by fixing a wind-distributing pipe inside conventional rollers drier
Hot wind cloth wind mode, be directly entered hot wind in air hose from air blower, and small by uniformly opening up around three sections of tube walls
Hot wind is uniformly distributed by hole, and three sections of tube wall percent opening gradients rise, and effectively prevents hot wind state axis in original drying process
To the problems such as being unevenly distributed, smoked sheet multiple roasting drying efficiency and effect are substantially increased.
