Abstract
The utility model discloses a control device for stabilizing of hot wind humidity of drum drying of pipe tobacco. Fresh wind enters a rotary drum after going through a fresh wind volume control device and being heated by a hot wind temperature control device. A hot wind moisture removal system is arranged at a tobacco scrap outlet end of the rotary drum, and a drum wall temperature control device is disposed outside the rotary drum. A steam supply control device is additionally arranged between the fresh wind volume control device and the hot wind temperature control device. A proportion-integration-differentiation (PID) control unit is connected with the steam supply control device, the fresh wind volume control device and a fresh wind temperature and humidity detection element. The control device for stabilizing of the hot wind humidity of the drum drying of the pipe tobacco can be utilized to achieve that hot wind humidity in the drum drying process of the pipe tobacco cannot be affected by seasons and weather conditions, and therefore technological parameters of the drum drying can be stabilized, and stability of sensory quality of the dried pipe tobacco can be guaranteed.
Description
Technical field
The utility model relates to tobacco business, the particularly stable control of Tobacco drying link cylinder class tobacco shreds drying hot blast humidity in the tobacco processing course.
Technical background
The tobacco shreds drying operation is one of critical process in the cigarette fiber tow production process.In this operation, through drying, make pipe tobacco fully loose, and produce certain curling, increase the filling capacity of pipe tobacco.Advantages such as drum apparatus has that treating capacity is big, flexible operation, expense are cheap relatively become the dry main mode of tobacco cutting process material.
The process of moisture from the pipe tobacco diffusion into the surface to hot blast is the important step of dry materials mass transfer in the cylinder.The main motive force of this mass transport process is the pressure differential of moisture dividing potential drop in pipe tobacco surface moisture dividing potential drop and the hot blast.Pipe tobacco surface moisture dividing potential drop and pipe tobacco temperature correlation, and the humidity of hot blast moisture dividing potential drop and hot blast is closely related.Conventional rollers class tobacco shreds drying device is as shown in Figure 1, and fresh wind gets into cylinders through hot blast temperature control device 2 heating behind fresh wind air quantity controller 1, is provided with the hot blast moisture discharge device in the pipe tobacco port of export of cylinder.The hot blast of fresh wind does not circulate in cylinder, and its source is the fresh air in the environment, so the humidity of environmental air determined the humidity of hot blast, and the transfer rate of moisture from the pipe tobacco diffusion into the surface to hot blast had significant role.
Conventional rollers class tobacco shreds drying device adopts stablizes hot blast air quantity and hot blast temperature, is arranged at the outer barrel temperature control equipment of cylinder and regulates cylinder barrel temperature according to outlet pipe tobacco moisture content.Under different seasonal and the weather condition, the humidity of environmental air has than great fluctuation process (relative humidity 20%～80%), causes the humidity of hot blast also to exist than big-difference.In actual production process; Under different seasonal and the weather condition, even other process conditions are in full accord, because the greatest differences of the humidity of environmental air; The average fluctuation range of cylinder barrel temperature reaches ± and 10 ℃, aesthetic quality's stability of pipe tobacco after the drying is caused certain influence.
Summary of the invention
To the problems referred to above that exist in the prior art; The utility model patent provides a kind of control device that is used for stablizing cylinder class tobacco shreds drying hot blast humidity; Utilize this device can realize that the humidity of pipe tobacco roller drying process hot blast does not receive the influence of season and weather condition; Thereby stablize the technological parameter of roller drying, guarantee dry back pipe tobacco aesthetic quality's stability.
The technical solution of the utility model is:
A kind of control device that is used for stablizing cylinder class tobacco shreds drying hot blast humidity; Fresh wind gets into cylinder through the heating of hot blast temperature control device behind fresh wind air quantity controller; The pipe tobacco port of export in cylinder is provided with the hot blast moisture discharge device, and a barrel temperature control equipment is arranged at outside the cylinder; It is characterized in that: increase is provided with a steam and applies control device between fresh wind air quantity controller and hot blast temperature control device, and a PID control module connects this steam and applies control device, fresh wind air quantity controller and a fresh wind-warm syndrome moisture detection device.
The usefulness of above-mentioned technical solution is:
The utility model is set at 85%RH (25 ℃) with fresh rheumatism degree controlling value; This value is greater than the surrounding air humidity under most conditions; And steam pipework of setting up and PID control module can replenish steam to fresh wind automatically and effectively according to temperature, the Humidity Detection value of fresh wind air quantity of production process and fresh wind; Avoided changing influence to hot blast humidity because of surrounding air humidity under Various Seasonal and the weather condition; Increase substantially the stability of production process technology condition under Various Seasonal and the weather condition, guaranteed the cigarette product quality of stability.Through test contrast, before and after technology was implemented, under different seasonal and the weather condition, other process conditions were in full accord, the average fluctuation range of cylinder barrel temperature by ± 10 ℃ be reduced to ± 2 ℃.

The specific embodiment
A kind of control device that is used for stablizing cylinder class tobacco shreds drying hot blast humidity as shown in Figure 2; Fresh wind gets into cylinder through 2 heating of hot blast temperature control device behind fresh wind air quantity controller 1; The pipe tobacco port of export in cylinder is provided with the hot blast moisture discharge device, and a barrel temperature control equipment 3 is arranged at outside the cylinder.The utility model increases between fresh wind air quantity controller and hot blast temperature control device and is provided with a steam and applies control device; This steam applies the air bladder valve 6 that is provided with on the control device vapor injection line and is connected PID control module 5 with mass flowmenter 7, and this PID control module 5 connects a fresh wind air quantity controller 1 and a fresh wind-warm syndrome moisture detection device 4 simultaneously.The fresh rheumatism degree of the utility model controlling value is set at 85%RH (25 ℃), and temperature, Humidity Detection value according to fresh wind air quantity of production process and fresh wind calculate the steam applied amount by the PID control module, applies control device completion steam by steam and applies.
