Description
Technical field
The invention belongs to Cigarette processing processing quality technical field, be specifically related to the reverse-flow hot blast of a kind of improvement
The device of tobacco leaf moisting machine leaves moisting effect.
Background technology
Hot air conditioning cylinder all it is configured with, before its objective is that air exercise leaf is destemming before the threshing machine of Threshing Re-dry Product Line
Nicotiana tabacum L. carry out last warming and humidifying, by improving the temperature of Nicotiana tabacum L. and moisture, on the one hand improve cigarette
The resist processing of leaf, on the other hand makes Nicotiana tabacum L. under suitable temperature, moisture, and stalk, leaf attachment region occur
" stress concentration " phenomenon, it is simple to realize stalk, leaf separation beating leaf operation.And moisten based on reverse-flow hot blast
Leaf machine advantage soft, progressive, that heat Nicotiana tabacum L. in the entire process, obtains extensively at each threshing and redrying production line
General use.
But reverse-flow hot air conditioning cylinder there is also clearly disadvantageous: the high temperature low humidity after heater heats
Hot blast from tobacco leaf moisting machine discharge end enter cylinder, to feed end flow during, can constantly absorb sky
Between and Nicotiana tabacum L. in moisture improve self relative humidity.This kind " baking leaf " phenomenon is near tobacco leaf moisting machine
The rear of discharge end is especially apparent, and result makes embrittlement after the Nicotiana tabacum L. dehydration that portion of water is little, moisture holding capacity is poor,
Degrading resistance property reduces, and increases marking and consumes.
In view of the existence of the problems referred to above, existing a kind of method of needs research is optimized perfect.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, it is provided that a kind of improvement reverse-flow hot blast profit cutting rear cigarette block
The device of leaf machine leaves moisting effect, it is possible to eliminate " baking leaf " phenomenon of the hot blast of reverse-flow hot air conditioning cylinder,
Thus improve Storage duration water ratio uniformity, improve leaves moisting effect, reduce Nicotiana tabacum L. broken during beating leaf
Cigarette, offal amount.
Technology and method in order to solve the employing of the above-mentioned problem present invention are as follows:
A kind of device improving reverse-flow hot air conditioning cylinder leaves moisting effect, is installed in the heat before tobacco leaf moisting machine cylinder
On wind pipeline, including hot blast and heat nozzle, described hot blast nozzle of heating is connected with flow transducer and pressure
Sensor, described flow transducer is connected with the first Pneumatic diaphragm valve, and described pressure transducer is connected with the second gas
Dynamic membrane valve, described first Pneumatic diaphragm valve is connected with the waterpipe of tobacco leaf moisting machine cylinder, described second pneumatic
Membrane valve is connected with the jet chimney of tobacco leaf moisting machine cylinder.
Further, described hot blast nozzle of heating is connected with automatically controlled program and top_monitor software.
The advantage of the program is, hot blast is heated add wet process after present hot and humid state, high
The hot blast of temperature high humidity enters after tobacco leaf moisting machine cylinder, to space and Nicotiana tabacum L. release temperature and moisture, true to Nicotiana tabacum L.
Just play the leaves moisting effect of heating and moistening, eliminate unborn " baking leaf " phenomenon.
The program achieves and controls hot blast heating and moistening steam and the detection of water applied amount, regulation, it is achieved
When supplied materials moisture content is higher, adds less or do not add water when hot blast is applied steam, and when supplied materials moisture content is inclined
Time low, hot blast is applied steam and water simultaneously, and applied amount is fully achieved and automatically controls, and meets follow-up beating
Leaf operation is to Storage duration temperature and the requirement of moisture content.
Meanwhile, the program directly carries out warming and humidifying to hot blast owing to have employed, and can reduce original tobacco leaf moisting machine
Head, tail end steam and the usage amount of water, and reduce the steam usage amount of hot blast heat exchanger, make steam and
The utilization rate of water is improved, and reduces the energy resource consumption of leaves moisting process links generally.
The invention have the benefit that the phenomenon eliminating hot blast at tobacco leaf moisting machine rear " baking leaf ", fully
Having played the leaves moisting effect of hot blast, Storage duration water ratio uniformity is improved significantly, through actual measurement, profit
Rear Nicotiana tabacum L. moisture content standard deviation is reduced to 0.58% by original 0.83%；Use probability statistics, suitable after profit
The preferably Nicotiana tabacum L. moisture content probability of threshing process is brought up to 87.4% by original 74.2%.In wind dispensing work
Sequence link, in the case of not changing any wind dispensing parameter, the offal rate of generation is by original 2.2%
Left and right drops to about 1.78%, reduces about 0.42%, creates significant economic benefit.
Accompanying drawing explanation
Fig. 1 is existing tobacco leaf moisting machine pipeline structure figure；
Fig. 2 is that the tobacco leaf moisting machine pipeline of the present invention installs figure additional.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in further detail, but they are not to the present invention
The restriction of technical scheme.Based on present invention teach that any conversion made, all fall within the protection of the present invention
Scope.
Refering to shown in Fig. 1-2, a kind of device improving reverse-flow hot air conditioning cylinder leaves moisting effect, it is installed in
On hot air duct 2 before tobacco leaf moisting machine cylinder 1, including hot blast and heat nozzle 3, described hot blast is heated spray
