Abstract
The invention discloses a method for drying tobacco shreds in a drum way and accurately processing the tobacco shreds. The discharging end of a drum cut-tobacco drier is provided with a pressure detector, firstly, corresponding drum wall temperature, hot air temperature T1, hot air amount N, and moisture removing opening M are set according to the processing characteristics of the cigarette, the preheating is started, and the tobacco shreds can be gone into production after the temperature in the drum reaches the set requirement; secondly, the tobacco shreds are gone into production, the steam consumption is tracked and regulated so as to enable the steam consumption to be quickly stabilized to the set requirement, material water W at a discharge port during the processing is on the low side and or the high side, the moisture removing opening M is quickly regulated and the change of internal pressure P is monitored, if the P value exceeds a certain limitation, the hot air amount N is tracked and regulated so as to enable the temperature of the drum wall to be stabilized to the requirement of the processing parameter of the product. The method can effectively improve the stability, the uniformity and the controllability of the drum drying processing of tobacco shreds, realizes the drying accurate processing of the tobacco shreds, and realizes that the device of the method has simple structure, convenient manufacture and reliable performance.
Description
Technical field
The present invention relates to a kind ofly, particularly relate to and a kind of pipe tobacco is carried out drum-type drying accuracy method for processing, the invention still further relates to the device of this method of realization the pipe tobacco method for processing.
Background technology
It is requisite link in the cigarette process that tobacco shreds drying is handled, and its treatment effect is most important to the cigarette product aesthetic quality's, and particularly the suitable of barrel temperature selected for use and stable control.The stability, uniformity and the controllability that improve the tobacco shreds drying processing are difficult problems that needs to be resolved hurrily in the industry.
With regard to the drum-type cut-tobacco drier, can be divided into three sections in theory: front end dryer section, middle-end breeze way, rear end balancing segment, the distribution length of dryer section and balancing segment have determined dry employed barrel temperature, the corresponding variation that also determines the cigarette product inherent quality.The distribution of dryer section and balancing segment length then is decided by the size of intake and exhaust air rate.Exhaust air rate is greater than intake, and dryer section prolongs, balancing segment shortens, and uses baking temperature to reduce, and inner barrel presents negative pressure state simultaneously, otherwise otherwise.Existing control technology is only controlled the barrel temperature, and the inner barrel air pressure is not had monitoring means, in case the variation of intake and exhaust air rate occurs, the unstable phenomenon of barrel temperature control often occurs, causes the variation of product quality.
Summary of the invention
First technical problem to be solved by this invention provides a kind of processing stability height, controllability and preferably pipe tobacco is carried out drum-type drying accuracy method for processing.
Second technical problem to be solved by this invention provides a kind of device of this method of realization of simple in structure, dependable performance.
In order to solve the problems of the technologies described above, what the present invention adopted carries out drum-type drying accuracy method for processing to pipe tobacco, at original drum-type tobacco dryer discharging end configuration pressure detector P, its detection information and intake N and humidity discharging amount M set up chain control relation, the steps include: for the 1st step: set corresponding barrel temperature, hot blast wind-warm syndrome T1, hot blast air quantity N, humidity discharging aperture M according to the cigarette product processing characteristics, start preheating, treat to put into production after an interior temperature reaches the setting requirement; The 2nd step: drop into pipe tobacco production, follow the tracks of and adjust the hot blast air quantity, make it fast and stable and setting requirement, process middle outlet material moisture W changes, occur on the low side or higher, the variation of then rapid adjustment humidity discharging air quantity M, and monitoring internal pressure P is then followed the tracks of adjustment hot blast air quantity N if the P value surpasses certain limit; Make the barrel temperature stabilization in the requirement of product machined parameters.
In order to realize said method, device provided by the invention is: comprise the drum-type cut-tobacco drier, hot blast self-acting valve, automatic humidity discharging valve, dispose pressure detector at described drum-type tobacco dryer discharging end, described pressure detector and hot blast self-acting valve, the automatic chain control connection of humidity discharging valve.
That adopts technique scheme carries out drum-type drying accuracy method for processing to pipe tobacco, in implementing the tobacco shreds drying process, at certain concrete cigarette product, at first determine the barrel temperature and the inner barrel pressure parameter P of suitable processing, the barrel temperature is implemented stable control by quantity of steam, and internal pressure is then by adjusting intake N, humidity discharging amount M control.W is dried partially for the outlet moisture in cut tobacco, at first reduces humidity discharging amount M, and the variation of internal pressure P reaches certain limit, then corresponding reduction intake N, otherwise otherwise, thereby guarantee the stable of barrel temperature.Detect by internal pressure simultaneously and numerical value P change can also monitor air intake, whether air draft working properly, effectively instructs rapidly removing faults to guarantee the normal stable operation of equipment.
Drum-type cut-tobacco drier internal gas pressure Detection ﹠ Controling technology is to improve the stability, uniformity of tobacco shreds drying processing and the desirable technique of controllability.Drum-type cut-tobacco drier internal pressure Detection ﹠ Controling technology of the present invention has overcome the uncontrollable obstacle of original cooked mode bottom roll internal gas pressure.Simultaneously, traditional processing stability, the relatively poor problem of controllability have been solved.Pipe tobacco obtains heat by heat conduction, heat radiation form and dewaters in cylinder baking silk process, setting up a stable gas field in the inner barrel of drum-type cut-tobacco drier is the key that improves processing stability, controllability.
In sum, method of the present invention can effectively improve stability, the controllability that the pipe tobacco drum-type drying is handled, and realizes the processing that becomes more meticulous to tobacco shreds drying, realizes that the apparatus structure of this method is simple, easily manufactured, dependable performance.
