Described on-line control system (not shown) comprises temperature sensor, humidity sensor, the temperature rise sensor that is installed in the bakery 1, tobacco leaf water content checkout gear and PLC control centre (above equipment is not shown in the figures); The floor data in each stage in the detection bakery of temperature sensor, humidity sensor, temperature rise sensor and tobacco leaf water content checkout gear real-time online, control the transmission speed of tobacco leaf loop transmission 5, the thermal source supply size of the concentrated heating system 6 of tobacco flue-curing and air output, the exhaust air rate of tobacco flue-curing novel air duct system 7 respectively in real time by PLC control centre, accurately each stage parameter of control baking process is in the desired indicator biochemical reactions each stage in bake process in the tobacco leaf.
In conjunction with the embodiments, the concrete course of work of the present invention is done to describe in detail:
During the work of this tobacco flue-curing mechanized production system, clamping tobacco leaf on the cigarette car 52 of track driving-chain 50 at first, simultaneously, and the PLC control centre of on-line control system, the boiler heating of heating system is concentrated in control tobacco flue-curing, supplies with hot water in attemperater; After clamping finished, PLC control centre was by the drive unit of tobacco leaf loop transmission, and the cigarette car on the control drive track driving-chain enters the district that homogenizes in the bakery.
After tobacco leaf enters interior the homogenizing district of bakery on the cigarette car, PLC control centre controls tobacco flue-curing respectively and concentrates heating system and tobacco flue-curing novel air duct system to enter duty, the district that homogenizes at bakery, air-supply EGR and return air EGR by tobacco flue-curing novel air duct system, to entering different moisture levels in the bakery and the tobacco leaf of temperature regime, (concrete heating and dehumidification process is identical with the heating and dehumidification of dry section tobacco leaf to carry out preliminary heating and dehumidification, elaborate afterwards), after reaching the humidity and temperature conditions of unified area requirement, send into the dry section in the bakery; Then, in the dry section of bakery, filter by the air-supply EGR, remove impurity such as the interior airborne bulky grain dust of dry section, through the state point of dehumidifier dehumidifying section dehumidifying to the baking process requirement, deliver to heating period in air channel by breeze fan, after wind-water heat exchanger heating of heating system is concentrated in tobacco flue-curing in the air channel, deliver in the dry section again.In dry section in the tobacco flue-curing dehumidification process, after the air in bakery inner drying district heats through the tobacco leaf to dry section, after collecting through the current collector of return air EGR earlier, send back to the air-supply EGR by the road, the air-supply EGR is according to the detection of humidity sensor in the dry section; When needs increase fresh air is regulated the humidity in the bakery dry section, splitting leafy control valve by first of air-supply EGR regulates, the input quantity of loopback air behind the outside air input quantity that the control bakery is outer and the baking tobacco leaves, and then definite outside air and loopback Air mixing ratio, reduce the humidity load of air in the bakery dry section, after mixed processing, again behind air-supply EGR heating and dehumidification, send into the heating that circulates in the dry section of bakery.In this circulation heating and dehumidification process, the humidity value that the return air EGR detects according to humidity sensor in the dry section simultaneously, compare with standard value, when the air humidity in the bakery dry section is loaded greater than technological requirement, the exhaust air rate that leafy control valve is regulated humid air in the dry section 1 is split in control second, and by wet-emitting blower and exhaust outlet, the air of discharge section high humidity is finished in the bakery dry section tobacco leaf heating and dehumidification that circulates is for the first time handled outside bakery.Certainly, in the tobacco flue-curing dehumidification process, also can utilize extraneous Changes in weather in dry section, the air after changing by the external world is regulated the humidity in the bakery dry section.
Tobacco leaf is after the dry section heating and dehumidification finishes, PLC control centre is by the drive unit of tobacco leaf loop transmission, cigarette car on the control drive track driving-chain enters the auxiliary region in the bakery, according to tobacco leaf humidity and drying regime, tobacco leaf is carried out redrying or moisture regain processing, when tobacco leaf humidity does not also reach desired standard, by the heating and dehumidification device (not shown) in the auxiliary region, the tobacco leaf that had toasted is carried out redrying, make tobacco leaf reach predetermined water content; Too dry when tobacco leaf, humidity is crossed when low, by in the auxiliary region the sprayer unit (not shown), the tobacco leaf that has toasted is carried out spraying and dampening handles, make tobacco leaf be unlikely to overdrying; After the redrying or moisture regain processing of auxiliary region, tobacco leaf is sent bakery, finish cyclic process one time.
PLC control centre by on-line control system, the drive track driving-chain cycle operation of control tobacco leaf loop transmission, constantly will enter tobacco leaf in the bakery, concentrate the heating and dehumidification of heating system and tobacco flue-curing novel air duct system through tobacco flue-curing after, send bakery, finish the cyclic process of tobacco leaf.
Tobacco flue-curing mechanized production system of the present invention can also have other distortion, can be belt-type or other forms as track; Heating system can be heat pump or other heating plants; The air channel can be the air channel of rectangular duct or other types, and air outlet can be other form air ports of similar air diffuser; Control system can be Single-chip Controlling etc.; In a word, do apparent change according to the prompting of above-mentioned example, and other every change that does not break away from patent essence of the present invention all should be included within the described scope of claim.
