Description
Technical field
The present invention relates to tobacco manufacture field, relate in particular to a kind of method of cutting rear moisture of cut stem qualification rate by controlling the raising of terrier machine amount of water.
Background technology
Stem processing mainly comprises that soaking stalk machine soaks stalk, terrier machine terrier, terrier storage cabinet terrier storage, cuts the operations such as stem.Cutting rear moisture of cut stem is an important index in Cigarette processing production process, in tobacco manufacturing, moisture of cut stem is an extremely important factor in scrap prodn. line production process, has determined flexibility, plasticity and the resistance to processability of stem, affects igniting and sucking quality and the physicochemical property of cigarette.If it is bigger than normal to cut rear moisture of cut stem, can cause follow-up baking stem process energy consumption to increase, entreprise cost rises; Moisture is less than normal, can cause the unusual fluctuations of the physical and chemical index such as tobacco fill value, resistance to suction, affects consumer's interests.
In prior art, the manufacturing procedure of stem mainly by soaking stalk machine, terrier machine, terrier storage cabinet, cut the operations such as stem and form.Cut the control of rear moisture of cut stem and mainly set amount of water by terrier machine, water is evenly sprayed onto on the offal that enters terrier machine.
Offal moisture content is often subject to the impact of environment temperature, humidity and memory time.Stalk storage cabinet place of a lot of tobacco processing enterprise is without constant temperature, humidity control; simultaneously; offal after terrier needs transhipment, stores in workshop; in the time that dry offal in season is stored more than 4 hours; easily cause offal moisture loss in stalk cabinet; and the amount of water of setting terrier machine is owing to there is no concrete control method, so often cause cutting rear moisture of cut stem qualification rate lower, impact is cut rear moisture of cut stem qualification rate and is dried stem crudy.Therefore need to improve the method for cutting rear moisture of cut stem qualification rate by a kind of by controlling terrier machine amount of water; for the offal of the various trades mark; in process of production, consider that temperature, humidity and time causes the impact of offal moisture content, these influence factors are compensated.
Summary of the invention

As preferably, described significance is 5%-15%.
As preferably, described significance is 5%-15%.
Compared with prior art, the beneficial effect for the method for controlling terrier machine amount of water of the present invention is:
1, by environment temperature, ambient humidity, the impact of the time in terrier storage cabinet of storing on stem moisture content; control terrier machine amount of water; caused the variation of stem moisture content to compensate these factors; improve and cut rear moisture of cut stem qualification rate, guaranteed igniting and sucking quality and the physicochemical property of follow-up finished cigarettes.
2, according to the method, make terrier machine amount of water question blank, operating personnel can show according to this, control fast, efficiently terrier machine amount of water, are conducive to improve production capacity.
The specific embodiment
Below in conjunction with specific embodiment, the method for controlling terrier machine amount of water of embodiments of the invention is described in further detail, but not as a limitation of the invention.
Tobacco stem shred moisture content is in tobacco processing scrap prodn. line production process, affects extremely important factor of finished cigarettes igniting and sucking quality and physicochemical property.In the processing of offal, offal cleans through soaking stalk machine, removes the dust of offal, then enters terrier machine through adding water terrier, enters terrier storage cabinet after processing, after terrier storage, enters silk cutting machine and carries out chopping, reinforced through stalk charger after chopping.In this process, by terrier machine, offal is added water, make the moisture content of offal reach one and cut the desired target moisture content of rear stem, to guarantee the carrying out of subsequent handling.Due to the moisture-absorption characteristics of offal, the time that temperature, humidity and the offal of offal environment of living in (for example plant building) storE in terrier storage cabinet has a great impact the moisture content of offal, and between them, has the associated change relation of highly significant.
The control terrier machine amount of water that passes through of embodiments of the invention improves the method for cutting rear moisture of cut stem qualification rate, comprises the following steps:
S1: take stem from terrier to cutting environment temperature, ambient humidity stalk process, the numerical value that storEs the amount of water of time in terrier storage cabinet, terrier machine and cut rear stem moisture content is one group, gathers many this numerical value of group.The explanation as an example of workshop actual production example, records environment temperature in normal productive process, ambient humidity, storE time in terrier storage cabinet (pressing the cabinet time), terrier machine amount of water and cut the multi-group data of rear stem moisture content, as shown in table 1.
Certainly, well known to a person skilled in the art, the data group number of collection is more, is more conducive to linear regression analysis.In table 1, gathered 50 groups of data and described, for example gathering P1.1 is 23.5 ℃, and P1.2 is that 42.2%, P1.4 is 365 minutes, and Y1 is in 35.2% situation, the data that terrier machine amount of water is P1.3.The scatter diagram of cutting rear stem moisture content and environment temperature, ambient humidity, storing time in terrier storage cabinet between (pressing the cabinet time), these four independents variable of terrier machine amount of water by making, find to cut rear stem moisture content therewith four independents variable there is linear relationship.
