Background technology
In the prior art, the conventional tumble that cut tobacco, stem drying equipment are mainly used dries silk, two-part cut-tobacco drier, air-flow
The equipment such as drying, fluidized bed drying, by the heating to cut tobacco, stem, make moisture be changed into gaseous state, depart from cut tobacco and stem, because
This processes that intensity is universal higher in process of production, and roller dries silk barrel temperature, and fluidized bed drying gas flow temperature is basic at 120 DEG C
More than, pneumatic conveying drying hot blast temperature highest is even up to more than 280 DEG C, and processing intensity is big, and the fragrant chemical composition of the cause in cut tobacco is damaged
Mistake is more, and the small molecule for especially having obvious positive influences to cigarette quality causes fragrant chemical composition loss to become apparent, for cigarette,
Particularly high-grade cigarette product, its raw tobacco material quality selected is high, and shortcoming is few, and the processing of high intensity often brings pipe tobacco product
The reduction of matter, therefore the processing intensity of reduction tobacco drying process, for high-grade cigarette, demand is more urgent.
The content of the invention
The present invention, which is provided, to be provided a kind of hypoxemia low pressure drum-type cut-tobacco drier according to the deficiencies in the prior art and dries silk method, should
Simple in equipment, it is easy to operate, by reducing the air pressure inside baking silk cylinder, so as to reduce the boiling point of water and the oxygen of inner barrel
Gas content, realizes the drying process of cut tobacco at a lower temperature, simultaneously because being greatly reduced for inner barrel oxygen content, can
To reduce oxidation reaction of the cut tobacco in cut tobacco drying, the small molecule aroma component inside tobacco leaf is kept to greatest extent.
The technical scheme that the present invention is provided：A kind of hypoxemia low pressure drum-type cut-tobacco drier, including support, electrical heating dry silk
Roller and drum drive mechanism, feed space is provided with the feed end for drying silk roller, and discharge end is provided with discharge chamber, it is characterised in that：

Electric heating device, the electric heating device electric heater unit is resistive heater or electrothermal heating rod or heating coil.
The present invention preferably technical scheme：Sealing strip is provided with each gas lock blade and airlock chamber engagement edge.
The present invention preferably technical scheme：The charging aperture being opened in airlock chamber and discharging opening are separately positioned on not phase
In two adjacent seal cavities.
A kind of hypoxemia low pressure that the present invention is provided dries silk technique, using drum-type cut-tobacco drier, it is characterised in that in electrical heating
The charging aperture of silk roller is dried provided with charging gas lock, and discharging opening is provided with air extractor, its specific steps provided with discharging gas lock, cylinder
It is as follows：
(1) before charging, it is evacuated by air extractor to drying silk roller, air pressure in silk roller will be dried and be reduced to a standard
The 20%-50% of atmospheric pressure；
(2) when the pressure that step (1) is dried in silk roller reaches design requirement, pipe tobacco is locked into by feeding gas and rolled into baking silk
In cylinder, the inner wall temperature for controlling to dry silk roller is 60-90 DEG C, and pipe tobacco is defeated to discharging opening in the presence of the rotation of roller and harrow nail
It is sent into row and dries silk, controls the air pressure in roller to be 0.2-0.5 by pressure test device and air extractor in cut tobacco drying
Standard atmospheric pressure；The pipe tobacco being baked dries silk roller by the gas lock output that discharges, into next process.
The present invention before use, by gas extraction system extract cylinder in air, reduce inner barrel air pressure and
Oxygen content, makes pressure in cylinder be reduced to the 20-50% of normal atmosphere (An), the floating-point of water is changed into 60-80 DEG C, in relatively low baking
At a temperature of silk, input and output material gas lock prevents the exchange of an inner air and outer air, prevents extraneous other gases from entering in cylinder, pressure in holding cylinder
Stable, when production starts, material is locked into baking silk cylinder by feeding gas, is dried silk cylinder and is heated up by electric heater unit, to pipe tobacco
Dehydration is dried, under relatively low pressure, temperature is less than the purpose that moisture vaporization can be achieved under the conditions of 100 DEG C in cylinder, real
The low-intensity processing of existing cut tobacco.The cylinder of the present invention is heated up using electrically heated mode, and temperature can be adjusted automatically according to demand
Section, adjustment amplitude is big, and minimum temperature can be less than 100 DEG C, adapts to large range of temperature adjustment, and discharging gas lock blade journey is clockwise
Rotation, sends out material, and discharging gas lock can prevent that air enters in cylinder outside cylinder while material detachment roller, in holding cylinder
Pressure is stable, and gas extraction system possesses in extraction cylinder atmospheric pressure in air reduction cylinder, extract moisture that cut tobacco drying process produces,
Dedusting, a variety of functions of holding cylinder internal pressure strong stability.
Whole equipment reasonable in design of the present invention, exchange construction is simple and convenient to operate, and is dried by reducing inside silk cylinder
Air pressure, so as to reduce the boiling point of water, just can make water be converted into gas, reduce the processing of production process at a lower temperature
Intensity, can be compared with the drying to cut tobacco be realized, simultaneously because air is largely extracted out in cylinder, in drying equipment under low-intensity
Portion's oxygen content is substantially reduced, and reduces the loss for answering oxidation reaction to cause of cut tobacco drying small molecule aroma component, limits
Keep tobacco leaf inside small molecule aroma component, the organoleptic quality of high-grade tobacco leaf can be kept, thus improve processing after roll up
The quality of cigarette.
