Description
Technical field
The present invention relates to technical field of tobacco processing, relate in particular to the method that control cigarette throwing cylinder class receives warm working procedure processing quality conformance.
Background technology
Along with the raising of cigarette brand concentration degree, the product of the same specification of same brand increases in the situation of different factories processing gradually, keeps the uniformity of different factories product processed quality and style to become the current technical problem that needs to be resolved hurrily.The uniformity of different factories product processed liquor style not only depends on employed raw material, material, essence and flavoring agent, and also with cigarette processing, especially each working procedure processing quality conformance of throwing is closely related.
Cigarette throwing is made up of a plurality of operations, and wherein throwing flow process intermediate roll class receives warm working procedure processing process that physical quality, chemical quality and the aesthetic quality of raw material are had appreciable impact (" tobacco science and technology ", 2005 (3): the 3-6 page or leaf; 2005 (11): the 7-9 page or leaf; " Chinese tobacco journal ", 2007,13 (4): the 1-5 page or leaf).Cigarette throwing process cylinder class receives warm operation to comprise operations such as loosening and gaining moisture, reinforced leaves moisting, smoked sheet heat, roller drying; Its operation task is to change tobacco temperature and moisture content through modes such as uperize, hot air convection or the conduction of barrel heat, to satisfy the following process requirement and to reach the purpose of improving the aesthetic quality.
At present, to receive the method for warm working procedure processing quality conformance be through guaranteeing that working procedure processing physical quality index and the consistent of technological parameter realize to the index drum class.Control processing physics quality index unanimity only can guarantee to satisfy back working procedure processing requirement at the goods physical quality in consumption of raw materials and the process, can not guarantee that the material aesthetic quality is consistent with chemical composition change; Because when same raw material is produced in different factories; The cylinder class that is adopted there are differences by warm processing apparatus structure, production capacity and machining medium etc., and under same process parameter condition, temperature of charge and heated time are also not quite identical; The research proof; In the material process variation of aesthetic quality and chemical composition depend primarily in the process material temperature change with heated time (" tobacco is scientific and technological ", 2009 (12): the 9-12 page or leaf), therefore; Because existing method is difficult to guarantee that throwing process cylinder class receives warm operation temperature of charge consistent with heated time, thereby influences final products style and aesthetic quality's uniformity.
Summary of the invention
The object of the invention provides a kind of method that cigarette throwing cylinder class receives warm working procedure processing quality conformance of controlling to above-mentioned technical deficiency just.This method is consistent with suffered temperature process time in roller equipment through the control material, guarantees that the cylinder class receives warm working procedure processing quality conformance.
The objective of the invention is to realize through following technical scheme:
Control cigarette throwing cylinder class of the present invention receives the method for warm working procedure processing quality conformance, may further comprise the steps:
(1), under normal production conditions; Measure cigarette brand output enterprise throwing cylinder class and receive warm operation (this operation comprises that loosening and gaining moisture, reinforced leaves moisting, smoked sheet heat, drum-type leaf silk warming and humidifying and drum-type leaf silk drying etc.) material process time; And roller equipment imports and exports temperature of charge and material some somes temperature of process in cylinder, the drafting material roller equipment process temperature with process time change curve 1..
Material mensuration process time in this step can adopt label method (" cigarette process standard ", Central Party Literature Publisher, the 90th page) or the weight method in the known technology.
The method that described weight method is measured material process time is following: set cylinder blower fan frequency, drum rotation speed, mass flow; Starting drive, treat that the cylinder input and output material is stable after, close feed arrangement, material in the cylinder is discharged collects, with pipe tobacco weighing on an electronic scale of collecting, promptly obtain material lagging amount in the cylinder.Confirm the process time (t) of material in cylinder according to hold-up (W) and mass flow (Q):
(2), select the identical throwing cylinder class of cigarette brand input enterprise to receive warm operation, measure the process time of material in cylinder.
(3), regulate the material that cigarette brand input enterprise selects and receive warm operation drum rotation speed, make consistent (△ t≤5s), definite enterprise's drum rotation speed of importing of material process time with cigarette brand output enterprise.
(4), under the drum rotation speed condition that step (3) is confirmed; Other apparatus and process parameters adopt the normal production conditions processing of input enterprise; Measure cigarette brand input enterprise same processes throwing roller equipment and import and export temperature of charge and material some somes temperature of process in cylinder, the drafting material roller equipment process temperature with process time change curve 2..
(5), comparison curves 1. with curve 2., relatively roller equipment is imported and exported some somes temperature of charge differences in temperature of charge and the process intermediate roll, through adjusting supplied materials state, makes inlet feed temperature be consistent (△ T≤1 ℃); To the manufacturing procedure characteristics, regulate material and receive warm machined parameters (loosening and gaining moisture, reinforced leaves moisting, smoked sheet heat, to receive warm machined parameters be return air temperature to drum-type leaf silk warming and humidifying equipment; It is barrel temperature, hot blast temperature and humidity discharging aperture that the drum-type cut tobacco drying equipment receives warm machined parameters), make material outlet temperature consistent (△ T≤1 ℃); Through regulating mass flow, make in the process intermediate roll each point for measuring temperature temperature of charge change consistent (△ T≤2 ℃);
(6), the throwing of adopting above-mentioned steps to confirm receives warm operation roller equipment working process parameter, enterprise carries out ordinary production in the cigarette brand input.
It is to record through being arranged on roller equipment import and export infrared radiation thermometer that mensuration roller equipment in step (1), (4) is imported and exported temperature of charge; Measuring tobacco temperature in the roller equipment, is through being fixed on several infrared temperature probes on the cylinder frame, sees through measurement window on the roller tube and shines in tube material and measure.
Advantage of the present invention is to guarantee that cigarette throwing cylinder class receives in the warm working procedure processing process temperature of charge consistent with heated time, helps guaranteeing that different factories same processes crudy is consistent.
