The technology for the production of cut rag tobacco includes the main technological processes:
- Moisturizing leaf tobacco
- Splitting and sаuсing of leaf tobacco
- Mixing different types of leaf tobacco
- Cutting leaf tobacco
- Drying cut tobacco
- Cooling cut tobacco
- Aromatization of cut tobacco
- Packaging of finished products
- Moisturizing leaf tobacco
In this primary, for the preliminary humidification of the tobacco, a “Quester” horizontal humidifier of sheet tobacco with a production capacity of 1 t / h is used. To pre-moisten the tobacco, it is necessary to remove the leaf or stripped tobacco from the bales on the unpacking table (item 1), loosen and lay the bale on a layer no more than 15 cm thick and feed into the horizontal Quester humidifier (item 2)
This machine is a pore thermally protected tunnel with steam nozzles, inside which a segment belt conveyor made of stainless steel with holes for steam penetration moves at a given speed. Steam is supplied from the bottom and from the top of the conveyor by spraying steam through the nozzles. Due to this, the leaf tobacco is pre-moistened.
The need for this machine in steam – 400 kg / hour
During the movement of leaf tobacco through the steam tunnel, the moisture content of leaf tobacco increases from 10-13% to 16-18%
Splitting and sаuсing of leaf tobacco
After moistening leaf tobacco in a horizontal humidifier, by means of an inclined tobacco cleaver conveyor (pos. 3) and a vibratory conveyor (pos. 4), leaf or stripped tobacco enters the “Drum for cleaving and saucing leaf tobacco” (pos. 5) with a capacity of 1 t / hour
This drum is a food grade stainless steel cylinder on rollers with a slope of 3%, which can rotate around its axis in different directions. This drum is equipped with both steam nozzles and nozzles for dispensing preheated sauce (mixture of monopropylene glycol with tobacco sauces)
Also, in this drum, the tobacco bales are stratified into separate sheets for better absorption of the sauces.
Mixing monopropylene glycol with tobacco sauces and feeding it into the drum for cleaving and sаuсing takes place in the “Sauce Kitchen” (item 8)
Mixing different types of leaf tobacco
After the Drum, the cuttings and sauced leaf tobacco with the help of a vibrating conveyor (Pos 6), goes to the “Separator” (Pos 7).
The separator is designed to separate solid impurities in tobacco such as stones, iron. After the separator through the pipe system and with the help of the aspiration system, the tobacco enters the “settling chamber” (Pos 9)
It makes for stopping tobacco and transferring it to the horizontal transverse conveyor (Pos 10), then to the longitudinal application for filling “Mixers of leaf tobacco” (Pos 11, Pos 12)
In these mixers, leaf tobacco is mixed by grade. In them, leaf tobacco is laying down, moisture redistribution and impregnation of leaf tobacco with sauces.
The volume of each mixer is 1000 kg / leaf tobacco.
After lying down, the tobacco goes to the vibrating conveyor (Pos 13), then to the belt conveyor (Pos 14). Above these conveyors there is a “Magnet” (Pos 16) for catching metal parts to protect the tobacco cutting machine.
Cutting leaf tobacco
After mixing leaf tobacco in mixers, leaf tobacco using a vibrating conveyor (Pos 13) (, a belt conveyor (Pos 15) enters the tobacco cutting machine
tobacco cutting machine KTH 8 (Pos 17)
This machine is designed for cutting tobacco sheets with a moisture content of up to 22%. It Allows to cut tobacco sheet with fiber width from 0.5 to 1.5 mm. With capacity up to 1t / hour/
Drying cut tobacco
After cutting leaf tobacco in a tobacco cutting machine, the cut tobacco through a belt conveyor (Pos 18), then with the help of a vibrating conveyor (Pos 19), gets into the “Drying drum of cut tobacco” (Pos 20). This drum is designed for drying cut tobacco. During the drying process, the moisture content of the cut tobacco is brought to the specified moisture content, which corresponds to 13.5-15%.
Drying occurs due to the supply of water vapor to special steam lines in the inside of the drum. This leads to heating of the drum jacket and, due to this, the tobacco is dried.
After the drying drum, dried tobacco with a given moisture content through a belt conveyor (Pos 22) enters the cooler.
At this stage, the cut or extended tobacco stem is added to the cut tobacco with the help of the storage feeder for feeding the tobacco strand (Pos 23).
Cooling cut tobacco
Since after drying the tobacco in a drying drum and adding an extended(cut) stem, the tobacco goes hot enough with a temperature of up to 50 degrees Celsius.
In order for tobacco aromas not to evaporate during tobacco aromatization, it is necessary to cool the cut tobacco to 30 degrees Celsius, for high-quality penetration of aromas into the tobacco body.
For these purposes, the Cutting Tobacco Cooler is used. (Pos 24)
Cooling takes place by blowing the cut tobacco with ambient air using nozzles and fans built into the cooler.
Aromatization of cut tobacco
After the cut tobacco is cooled down to 30 degrees Celsius, the cut and extended tobacco is fed by means of a belt conveyor (Pos 25) into the Drum for aromatization of cut tobacco with an aroma supply device (Pos 28)
In this drum, the cut tobacco is uniformly mixed with the cut (extended) stem and the tobacco aromatization process takes place.
Then the tobacco flavored and mixed with a vein through a belt conveyor (Pos 27) enters the storage box between the cut tobacco box (Pos 29) and goes to the packaging of finished products (Pos 30).
