Description
Technical field
The present invention relates to the tobacco production and processing technology, particularly a kind of for the tobacco stalk pretreatment process to humidification and storage.
Background technology
The offal preliminary treatment mainly refers to humidification and the storage of offal, and the profit pretreated task of stalk and effect are to make the fibr tissue of offal and cell absorb moisture sufficiently uniformly, produces the wet effect of rising, and enlarges the volume of cell to a certain extent.In addition, in the pretreated process of offal, because the increase of offal temperature and moisture can also make its flexibility, plasticity and anti-processability be improved, thereby satisfy the technological requirement of deformation (press stalk and cut stem), reduce the fragmentation of offal in deformation process and grey the damage.
The offal preliminary treatment generally need be passed through: vacuum conditioning → feed liquid is washed stalk → once profit stalk → Terrier Storage → five operations of secondary profit stalk and is handled.Be that parcel post is tight with sack dress during the offal vacuum conditioning, press relatively more in fact between the parcel post, when vacuum conditioning and the contact-making surface of steam less, and the offal eucaryotic cell structure is tight, moisture is not easy to be penetrated in the offal histocyte; As by increasing steam pressure and moisture regain cycle, can turn black by the too high and feasible surperficial offal of Yin Wendu again.The effect that feed liquid is washed stalk mainly is that the minimizing offal is pressed the loss in the operations such as obstructing, cut stalk in later process for contained impurity, particularly nonmetallic inclusion in the further purification offal supplied materials.
After testing, adopt present tobacco stalk pretreatment process, the offal moisture content is 19.0% to the maximum behind the vacuum conditioning, and minimum is 15.43%, average out to 17.236%, and standard deviation is 0.969, moisture content is inhomogeneous; Migration rate of water only is 24.38% to the maximum, and minimum is 16.94%, and is average 19.907%, and standard deviation is 2.477, and migration rate of water is extremely unstable.Behind the vacuum conditioning and since offal through feed liquid wash stalk and once two operations of profit stalk time of handling of short duration, moisture can only fail to be penetrated into the offal cell interior on the offal surface.The offal doubling of Terrier Storage after 2 hours has slight crack, and the offal flexibility is poor, has vertically torn phenomenon separated but still in each other's thoughts.Can not provide necessary quality assurance to follow-up offal deformation process, producing stalk when back operation is produced, to sign the stalk number of blocks many, have the phenomenon that needle-holding hand is arranged after the stem expansion.
Summary of the invention
At above-mentioned the deficiencies in the prior art, the purpose of this invention is to provide a kind of tobacco stalk pretreatment process that the offal moisture content is even, turn-head-rate is stable that makes.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of tobacco stalk pretreatment process, its comprise the steps: offal get the raw materials ready finish after, at first carry out feed liquid and wash stalk operation, then carry out successively vacuum conditioning, once moisten stalk, Terrier Storage, secondary profit stalk, cut stem and stem expansive working.
Preferably, feed liquid is washed after stalk operation finishes, and uses the dolly that has the steam inlet hole to load offal and carries out the vacuum conditioning operation.
Preferably, before carrying out vacuum conditioning operation moisture regain, need to sprinkle water to offal.
Preferably, before cutting stem, need press stalk.
Preferably, once the profit stalk adopts the mode of washing stalk to carry out, and the water temperature during the washing stalk is 30～60 ℃, 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 is after finishing offal and getting the raw materials ready, at first carry out feed liquid and wash stalk, just carry out vacuum conditioning then, carry out feed liquid earlier and wash the moisture that stalk can increase offal, improve the shatter value of offal, like this when carrying out vacuum conditioning, can increase the contact area of offal and steam, make moisture be more prone to enter into the histocyte of offal, thereby improve the migration rate of water of offal, permeability and the uniformity of moisture, improve the offal pretreating effect.Offal is washed stalk operation processing back through feed liquid the stable processing quality of later process is played an important role, and is difficult for as pressing stalk that existing expansion, the stem expansion effect after the baking to a certain degree of stem broken, after cutting is fine, stalk is signed less, the stalk piece is few.
Above-mentioned explanation only is the general introduction of technical solution of the present invention, for can clearer understanding technological means of the present invention, and can be implemented according to the content of specification, below with preferred embodiment of the present invention and conjunction with figs. this patent is elaborated.
Description of drawings
Fig. 1 is the flow chart of the embodiment of the invention.
The specific embodiment
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 at first carrying out offal gets the raw materials ready, carry out feed liquid after offal is got the raw materials ready and finished and wash the stalk operation, the effect that feed liquid is washed stalk mainly is in order to purify impurity contained in the offal supplied materials, nonmetallic inclusion particularly reduces offal and presses stalk in later process, cuts the loss in the operation such as stalk.After washing stalk through feed liquid simultaneously, can increase the moisture in the offal, improve pliability and the reliability of offal.To be placed on the dolly that has the steam inlet hole then with the offal that tobacco leaf was washed and carry out the vacuum conditioning operation, before carrying out vacuum conditioning, can on offal, spill a little water earlier, to increase the moisture in the offal.
With respect to using sack to load offal, offal is placed on the dolly that has the steam inlet hole can makes offal more loose, increase the gas permeability between offal, can improve the problem that offal turns black in the vacuum conditioning process.Dolly is provided with the steam inlet hole, can solve the moisture regain problem of non-uniform by steam by supercharging and the pressure differential of finding time to produce in when moisture regain.Carry out just carrying out vacuum conditioning after feed liquid is washed stalk, carry out feed liquid earlier and wash the moisture that stalk can increase offal, improve the shatter value of offal, like this when carrying out vacuum conditioning, can increase the contact area of offal and steam, make moisture be more prone to enter into the histocyte of offal, thereby improve the migration rate of water of offal, permeability and the uniformity of moisture.
Can moisten stalk after the vacuum conditioning operation is finished, profit stalk comprises and once moistens stalk, Terrier Storage, secondary profit stalk.Once the profit stalk adopts washing stalk mode to carry out, compare following advantage with other several profit stalk modes: 1) dirt and the part emplastic (as pectic substance) on offal surface can be washed off, avoid or reduce glutinous cutter, fouling and skidding in cutting the stem process, occurring, reach and both improve the chopping quality, prolong the effect of blade life again; 2) can utilize the fouling characteristics of offal, make the internal fiber of offal fully absorb moisture by " siphonage "; 3) can reduce run, drip, leak phenomenon in the offal processing procedure, reduce energy consumption, and operation is very simple, convenient.The stalk of profit stalk employing washing for the first time mode is carried out in this tobacco stalk pretreatment process, and the profit stalk can adopt the fluid bed mode to carry out for the second time.
When once profit is obstructed, the water temperature of washing stalk generally is set in 30～60 ℃ of scopes, the water consumption of washing stalk 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, in pressing stalk or chopping process, produces easily to make brokenly, and be that stem contains last rate and increases; Otherwise the offal surface moisture is too much, offal is run more in the chopping process cut mashed with the offal epidermis.The profit stalk can adopt the fluid bed mode for the second time, and general temperature should be controlled more than 80 ℃.Adopt the advantage of twice profit stalk mode to be: one can promote infiltration and the absorption of moisture, and two are conducive to the offal cell produces the wet effect of rising.After secondary profit stalk is finished, stalk be need press, stem and stem expansive working after being compacted to offal to a certain degree, can be cut.
This tobacco stalk pretreatment process is after finishing offal and getting the raw materials ready, at first carry out feed liquid and wash stalk, just carry out vacuum conditioning then, carry out feed liquid earlier and wash the moisture that stalk can increase offal, improve the shatter value of offal, like this when carrying out vacuum conditioning, can increase the contact area of offal and steam, make moisture be more prone to enter into the histocyte of offal, thereby improve the migration rate of water of offal, permeability and the uniformity of moisture, improve the offal pretreating effect.Offal is washed stalk operation processing back through feed liquid the stable processing quality of later process is played an important role, and is difficult for as pressing stalk that existing expansion, the stem expansion effect after the baking to a certain degree of stem broken, after cutting is fine, stalk is signed less, the stalk piece is few.
More than a kind of tobacco stalk pretreatment process that the embodiment of the invention is provided be described in detail; for one of ordinary skill in the art; thought according to the embodiment of the invention; part in specific embodiments and applications all can change; in sum; this description should not be construed as limitation of the present invention, and all any changes of making according to design philosophy of the present invention are all within protection scope of the present invention.
