Description
Technical field
The present invention relates to tobacco leaf production processing technology, particularly a kind of for the tobacco stalk pretreatment process to humidification and storage.
Background technology
Offal pretreatment mainly refers to humidification and the storage of offal, and the pretreated task of terrier and effect make the fibr tissue of offal and cell absorb moisture sufficiently uniformly, produces wet effect of rising, expands Magnocellular volume to a certain extent.In addition, in the pretreated process of offal, due to the increase of offal temperature and moisture, its flexibility, plasticity and resist processing can also be made to be improved, thus meet the technological requirement of deformation (pressure is obstructed and cut stem), reduce the fragmentation of offal in deformation process and damage with ash.
Offal pretreatment generally need through: vacuum conditioning → feed liquid is washed stalk → mono-time terrier → Terrier Storage → secondary terrier five operation and is processed.That parcel post is tight, presses more real between parcel post with sack dress during offal vacuum conditioning, less with the contact surface of steam when vacuum conditioning, and offal eucaryotic cell structure is closely, moisture is not easy to penetrate in offal histocyte; As by increasing steam pressure and moisture regain cycle, again can Yin Wendu too high and surperficial offal is turned black.Feed liquid washes the effect of stalk mainly in order to purify impurity, particularly nonmetallic inclusion contained in offal supplied materials further, reduces offal in later process pressure stalk, the loss of cutting in the operations such as stalk.
After testing, adopt current tobacco stalk pretreatment process, after vacuum conditioning, offal moisture content is 19.0% to the maximum, and minimum is 15.43%, average out to 17.236%, and standard deviation is 0.969, and moisture content is uneven; Migration rate of water is only 24.38% to the maximum, and minimum is 16.94%, and average 19.907%, standard deviation is 2.477, migration rate of water extremely unstable.After vacuum conditioning, the time of washing stalk and two the operation process of a terrier through feed liquid due to offal is of short duration, and moisture can only, on offal surface, be failed to penetrate into offal cell interior.The offal doubling of Terrier Storage after 2 hours has slight crack, and offal flexibility is poor, has longitudinally torn phenomenon separated but still in each other's thoughts.Necessary quality assurance can not be provided to follow-up offal deformation process, produce stalk label stalk number of blocks when rear operation is produced many, there is the phenomenon having needle-holding hand after stem expands.
Summary of the invention
For above-mentioned the deficiencies in the prior art, the object of this invention is to provide and a kind ofly make the tobacco stalk pretreatment process that offal moisture content is even, turn-head-rate is stable.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of tobacco stalk pretreatment process, it comprises the steps: after offal has been got the raw materials ready, and first carries out feed liquid and washes stalk operation, is then carrying out vacuum conditioning, terrier, Terrier Storage, a secondary terrier successively, is cutting stem and stem expansive working.
Preferably, feed liquid is washed after stalk operated, and uses the dolly with steam inlet hole to load offal and carries out vacuum conditioning operation.
Preferably, need to sprinkle water on offal before carrying out vacuum conditioning operation moisture regain.
Preferably, need to carry out pressure stalk before cutting stem.
Preferably, one time terrier adopts the mode of washing stalk to carry out, and water temperature during washing stalk is 30 ~ 60 DEG C, and the water consumption of washing stalk is the 30%-35% of tobacco stalk quality.
Preferably, the water consumption of washing stalk is 32% of tobacco stalk quality.
Technique scheme has following beneficial effect: this tobacco stalk pretreatment process completes after offal gets the raw materials ready, first carry out feed liquid and wash stalk, then just vacuum conditioning is carried out, first carrying out feed liquid and wash the moisture that stalk can increase offal, improving the shatter value of offal, like this when carrying out vacuum conditioning, the contact area of offal and steam can be increased, make moisture be more prone to enter into the histocyte of offal, thus improve the migration rate of water of offal, the permeability of moisture and uniformity, improve offal pretreating effect.Offal is washed after the processing of stalk operation through feed liquid and is played an important role to the crudy of later process is stable, as pressure stalk not easily broken, cut after stem have expansion to a certain degree, dry after stem expansion effect very well, stalk signs less, stalk block is few.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of description, coordinates accompanying drawing to be described in detail to this patent below with preferred embodiment of the present invention.
Accompanying drawing explanation
Fig. 1 is the flow chart of the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
As shown in Figure 1, this tobacco stalk pretreatment process comprises the steps: that first carrying out offal gets the raw materials ready, offal carries out feed liquid and washes stalk operation after having got the raw materials ready, feed liquid washes the effect of stalk mainly in order to purify impurity contained in offal supplied materials, particularly nonmetallic inclusion, reduces offal in later process pressure stalk, the loss of cutting in the operations such as stalk.Wash after stalk through feed liquid simultaneously, the moisture in offal can be increased, improve pliability and the reliability of offal.Then by the offal washed with tobacco leaf, the dolly be placed on steam inlet hole carries out vacuum conditioning operation, before carrying out vacuum conditioning, first can spill a little water on offal, to increase the moisture in offal.
Load offal relative to use sack, the dolly be placed on by offal with steam inlet hole can make offal more loose, increases the gas permeability between offal, can improve the problem that offal turns black in vacuum conditioning process.Dolly is provided with steam inlet hole, get damp again time can by steam by supercharging and find time generation pressure differential, moisture regain problem of non-uniform can be solved.Carry out just carrying out vacuum conditioning after feed liquid washes stalk, first carry out feed liquid and wash the moisture that stalk can increase offal, improve the shatter value of offal, like this when carrying out vacuum conditioning, the contact area of offal and steam can be increased, make moisture be more prone to enter into the histocyte of offal, thus improve the migration rate of water of offal, the permeability of moisture and uniformity.
Can carry out terrier after vacuum conditioning operation completes, terrier comprises terrier, Terrier Storage, secondary terrier.One time terrier adopts washing stalk mode to carry out, following advantage is had: 1) dirt on offal surface and part emplastic (as pectic substance) can be washed off compared with other several terrier mode, avoid or reduce cutting the glutinous cutter of appearance in stem process, fouling and skidding, reach and both improve chopping quality, extend again the effect of blade life; 2) the fouling feature of offal can be utilized, make the internal fiber of offal fully absorb moisture by " siphonage "; 3) the run, drip, leak phenomenon in offal processing procedure can be reduced, reduce energy consumption, and operation is very simple, convenient.In this tobacco stalk pretreatment process, first time terrier employing washing stalk mode is carried out, and second time terrier can adopt fluid bed process to carry out.
During a terrier, the water temperature of washing stalk is generally set within the scope of 30 ~ 60 DEG C, the water consumption that washing is obstructed is that the 30%-35% of tobacco stalk quality is advisable, be preferably 32%, unsuitable excessive or too small, if offal moisture content is too small, the wet effect of rising of offal is poor, flexibility is poor, and easily in pressure stalk or chopping process, generation is made broken, is that stem contains the increase of last rate; Otherwise offal surface moisture is too much, then easily make offal run in chopping process and more cut rotten with offal epidermis.Second time terrier can adopt fluid bed process, and general temperature should control more than 80 DEG C.Adopt the advantage of twice terrier mode to be: infiltration and the absorption that can promote moisture, two are conducive to offal cell produces wet effect of rising.After secondary terrier completes, pressure stalk need be carried out, to a certain degree can carry out afterwards cutting stem and stem expansive working offal is compacted to.
This tobacco stalk pretreatment process completes after offal gets the raw materials ready, first carry out feed liquid and wash stalk, then just vacuum conditioning is carried out, first carrying out feed liquid and wash the moisture that stalk can increase offal, improving the shatter value of offal, like this when carrying out vacuum conditioning, the contact area of offal and steam can be increased, make moisture be more prone to enter into the histocyte of offal, thus improve the migration rate of water of offal, the permeability of moisture and uniformity, improve offal pretreating effect.Offal is washed after the processing of stalk operation through feed liquid and is played an important role to the crudy of later process is stable, as pressure stalk not easily broken, cut after stem have expansion to a certain degree, dry after stem expansion effect very well, stalk signs less, stalk block is few.
Above a kind of tobacco stalk pretreatment process that the embodiment of the present invention provides is described in detail; for one of ordinary skill in the art; according to the thought of the embodiment of the present invention; all will change in specific embodiments and applications; in sum; this description should not be construed as limitation of the present invention, and all any changes made according to design philosophy of the present invention are all within protection scope of the present invention.
