Description
Technical field
The invention belongs to tobacco processing, particularly relate to a kind of control method of loosening and gaining moisture of tobacco.
Background technology
In the process of tobacco processing, need to carry out loose and warming and humidifying to smoked sheet in loosening and gaining moisture process, make the moisture content of smoked sheet and temperature increase to certain level, in order to meet the technological requirement of following process.The conventional cigarette loosening and gaining moisture control method of tradition is: production process is according to the trade mark by batch to produce, and the random outbound in tobacco leaf formulation storehouse pressed by every batch of sheet cigarette raw material.Loosening and gaining moisture operation is processed according to the order of sheet cigarette outbound, and moisture regain system carries out warming and humidifying according to mass flow.Loosening and gaining moisture discharge end Moisture Meter does not participate in controlling, and only plays the effect of monitor procedure, process exception warning.
Existing system exist deficiency mainly as follows: one be every trade mark every batch produce time, although formulation library presses tobacco leaf formulation outbound, but each tobacco leaf degree presses the random outbound of optimal path according to the dispatching patcher in composition of raw materials storehouse in same formula, therefore, moisture regain operation can only be processed according to the order of sheet cigarette outbound, because the processing characteristics of each grade tobacco leaf is different, tobacco leaf moisture-absorption characteristics and to heat performance different, causes moisture regain moisture content of outlet, drop temperature fluctuates larger; Two is that the infrared moisture meter applied in loosening and gaining moisture process is to better for one matter measurement effect, and the sheet cigarette raw material in tobacco leaf formulation is because of the difference such as the place of production, grade, storeroom differs greatly, and Moisture Meter is demarcated and can only be demarcated by whole tobacco leaf formulation, cause moisture measurement error larger.
Summary of the invention

(2) loosening and gaining moisture entrance belted electronic balance carries out weight weighing to each module sheet cigarette, wherein the operation principle of belted electronic balance calculates instantaneous weight flow according to weight signal, rate signal, then calculate weight build-up amount, when weighing, belted electronic balance is shown as 0;
(3) in system in advance stored according to Moisture Meter passage corresponding to rate of water absorption (< 1.8), (2.1 ~ 2.4), (1.8 ~ 2.1), (2.4 ~ 2.7), (2.1 ~ 2.4), (2.7 ~ 3.0) and (> 3.0), add water coefficient and the coolant-temperature gage supplemental characteristic that gets damp again, as table 1, the rate of water absorption information of each module cumulative weight information claimed and correspondence is inputted loosening and gaining moisture control system successively, and system is according to weight cumulative amount difference disparate modules;
(4) during production and processing, disparate modules carries out loosening and gaining moisture processing according to the order of module weight information input system each in step (3), the Moisture Meter passage that loosening and gaining moisture control system is corresponding according to first module rate of water absorption of input, add water coefficient, moisture regain coolant-temperature gage parameter is processed first module, belted electronic balance weighs first module weight simultaneously, when belted electronic balance weigh cumulative amount reaches first module weight of input system described in step (3), system will carry out processing process to second module, go down successively, until last module, add and undertaken by sequence of modules man-hour, but the sheet cigarette in same module is with machined.
(5) according to the moisture regain coolant-temperature gage, the belted electronic balance flow that arrange and the coefficient calculations amount of water that adds water, carry out loosening and gaining moisture to sheet cigarette, amount of water formula is as follows:
In formula, L is amount of water, and F is belted electronic balance flow, X
ofor loosening and gaining moisture operation moisture content of outlet setting value (X
oscope is 17 ~ 25%), X
ifor inlet water score value (X
iscope is 8 ~ 12%), k is for adding water coefficient.
In described step (1), number of modules N is generally 3 ~ 4, and n is the tobacco leaf degree number of lots processed to the maximum.
In described step (1), add and undertaken by sequence of modules man-hour, but the sheet cigarette in same module can with machined.
The module that table 1 sets according to rate of water absorption, Moisture Meter passage, add water coefficient, moisture regain coolant-temperature gage parameter:
| Moisture Meter passage | Add water coefficient | Moisture regain coolant-temperature gage (DEG C) | Rate of water absorption (%/min) |
| 3 | 0.75 | 60 | (2.1～2.4) |
