Abstract
Disclosed is a concurrent cut tobacco dryer with a drum, which can reduce over-dried cut tobacco. The utility model comprises a drum, a hot air inlet fan and a moisture discharging fan. The utility model is characterized in that the hot air inlet fan and the moisture discharging fan are both adopted to be variable frequency fans; and the time of drying the cut tobacco inside the drum is controlled by the adjustment of the air speed of the variable frequency fans. The utility model mainly changes the hot air inlet fan and the moisture discharging fan into the variable frequency fans. In three minutes before the production is started and over, the frequencies of the two fans are adjusted to be higher so that the air speed of the drum can be increased to 2.5 to 3 m/s from the normal speed of 1 to 1.5 m/s. The utility model improves the blowing action force, which makes the staying time of the cut tobacco is reduced to 2 to 2.5 minutes from normal 4 to 5 minutes. Thus, the produced over-dried cut tobacco is greatly reduced. With such method adopted, the produced amount of the over-dried cut tobacco generally occupies within 0.5 percent of the production capability, and the produced amount of the over-dried cut tobacco is reduced by 1 to 1.5 percent, and thus the fragments in the follow-up processes are obviously reduced. The consumption of the tobacco in a single box can be reduced by 0.2 to 0.3 kg per box with remarkable economic benefits.
Description
Technical field
The utility model relates to tobacco processing equipment, relates to a kind of downflow type cylinder cut tobacco dryer that can effectively reduce the over-dried cut tobacco phenomenon specifically.
Background technology
At present, domestic cigarette enterprise adopts the online leaf silk drying mode of " HT warming and humidifying+following current baking silk " more.Because dry initial period and ending phase mass flow reduce relatively, it is bigger to fluctuate, and environment temperature is higher relatively simultaneously, produces a large amount of over-dried cut tobaccos (moisture content of cut tobacco≤8%) inevitably, and this generation generally accounts for the 1.5-2% of production capacity.Because over-dried cut tobacco, moisture content of cut tobacco is little, in subsequent handling wherein become offal more than 50%, be discharged to the dedusting room, direct result increases the consumption of cigarette list case tobacco leaf, has reduced economic benefit of enterprises.In order to reduce the over-dried cut tobacco generation, many enterprises have adopted multiple measure to be avoided.Document " reducing the new method of baking silk over-dried cut tobacco " is seen " tobacco science and technology " 04 year 11 phase 10-12 page or leaf, summarized the measure that reduces over-dried cut tobacco: heat, annotate in the tube measure such as heat after vapour, cylinder speed governing, control heated wall temperature, control humidity discharging air quantity and the baking before the baking, introduced the material method of collecting together automatically that the improvement that this factory adopts " is done head ", the automatic blowing method and the on-line automatic aggregate measures that add the wet method combination of improvement " dried tail " simultaneously.Facts have proved, more than existing method can partly reduce the generation of over-dried cut tobacco, but general effect is bad, brings adverse consequences such as cylindrical shell shortening in service life simultaneously.
Summary of the invention
A kind of control mode that the purpose of this utility model designs at above-mentioned existing in prior technology problem just is simple, can obviously reduce the subsequent handling pipe tobacco makes the broken downflow type cylinder cut tobacco dryer that can effectively reduce the over-dried cut tobacco phenomenon.The present invention utilizes the wind effect of following current hot blast to pipe tobacco, and material is quickened to blow to the port of export, reduces the heat effect of barrel to material.
The objective of the invention is to be achieved through the following technical solutions: the downflow type cylinder cut tobacco dryer that reduces the over-dried cut tobacco phenomenon of the present utility model comprises baking silk cylinder and the hot blast air intake blower fan and the moisture-eliminating blower that are communicated with baking silk cylinder charging and discharging end, wherein: hot blast air intake blower fan and moisture-eliminating blower all adopt frequency conversion fan, by the drying time of wind speed adjustment control pipe tobacco in cylinder to frequency conversion fan.
In the present invention, described frequency conversion fan all adopts commercially available frequency conversion fan.
Main feature of the present utility model is to make hot blast air intake blower fan and moisture-eliminating blower into frequency conversion fan, in produce initial and finish preceding 3 minutes, heightens the frequency of two blower fans simultaneously, makes the cylindrical shell wind speed be increased to 2.5-3m/s from normal 1-1.5m/s.Improved the wind active force, made pipe tobacco holdup time 4-5 minute, reduced to 2-2.5 minute from normal drying.Thereby significantly reduced the generation of over-dried cut tobacco.Adopt over-dried cut tobacco generation after this method generally account for production capacity 0.5% in, can reduce over-dried cut tobacco generation 1-1.5%, thereby it is broken obviously to have reduced making of subsequent handling, the consumption of cigarette list case can reduce the 0.2-0.3Kg/ case, the economic benefit highly significant, equipment is changed little simultaneously.
Use this method and can reduce the generation of over-dried cut tobacco in the following current baking silk process effectively, have simultaneously control mode easy, do not damage cylindrical shell, do not influence the baking silk cylinder advantage in service life.
Description of drawings
Accompanying drawing is a structural front view of the present utility model.
Among the figure: 1, charging aperture, 2, a baking silk cylinder, 3, moisture-eliminating blower, 4, dedusting room conveyance conduit, 5, discharging opening, 6, heater, 7, the hot blast air intake blower fan, 8, the hot blast conveying pipe road.
The specific embodiment
The utility model is further described below in conjunction with accompanying drawing:
As shown in the figure: the utility model comprises baking silk cylinder 2 and the hot blast air intake blower fan 7 and the moisture-eliminating blower 3 that are communicated with baking silk cylinder charging aperture 1, discharging opening 5, be in existing following current cut-tobacco drier flow process, the hot blast drum porch installs frequency conversion fan additional, and the two ends of frequency conversion fan link to each other with hot blast conveying pipe road 8 with heater 6 respectively.The place installs frequency conversion moisture-eliminating blower 3 additional at cylinder humidity discharging mouth, and moisture-eliminating blower 3 two ends are connected with dedusting room conveyance conduit 4 with cylinder humidity discharging mouth respectively.
In use, when produce initial and finish preceding 3 minutes, heighten the frequency of hot blast air intake blower fan 7 and 3 liang of blower fans of moisture-eliminating blower simultaneously, make a baking silk cylindrical shell wind speed be increased to 2.5-3m/s from normal 1-1.5m/s.Improved the wind active force, made pipe tobacco holdup time 4-5 minute, reduced to 2-2.5 minute from normal drying.Use this method and can control the generation of over-dried cut tobacco in the following current baking silk process effectively, have simultaneously control mode easy, do not damage cylindrical shell, do not influence the advantage in its service life.
