Description
Technical field
The invention belongs to the tobacco processing equipment technical field, be specifically related to a kind of traditional steam source of change that utilizes and be tobacco high-efficiency feeding process and the device thereof of hot compressed air for thermal source.
Background technology
In the reinforced process of smoked sheet, be that feed liquid is put on the smoked sheet surface uniformly, because feed liquid has certain density and viscosity; Need to carry out mixing jetting by foreign substance; Existing feeding technique is that feed liquid is mixed at the mixing nozzle place through pipeline with saturated vapor, and is after-applied in smoked sheet through nozzle atomization, and this technology can reach feed liquid atomizing effect preferably; But because the steam that adds contains certain moisture content; To the control ratio of reinforced back smoked sheet moisture content difficulty, and the degree that steam is heated to feed liquid is uncontrollable, causes some unfavorable factors in the reinforced process; For example the effumability material in the feed liquid is caused the quickening evaporation rate, possibly cause deactivation reaction etc. because temperature is too high to biology enzyme, and then influence the improvement effect of feed liquid smoked sheet.For this reason, the inventor is through long term test research, develops to have sent out a kind ofly to become traditional steam source into compressed air is the tobacco high-efficiency feeding process and the device thereof of thermal source, overcome the deficiency of prior art, evidence, and effect is good.
Summary of the invention
First purpose of the present invention is to provide a kind of technological design reasonable, can effectively control and apply feed temperature, stablizes the tobacco high-efficiency feeding process of material moisture content.
Another object of the present invention is to provide a kind of isolated plant of realizing tobacco charging technology.
First purpose of the present invention is achieved in that and comprises following operation successively:
A, be that thermal source heats compressed air with steam, promptly steam and compressed air carry out exchange heat through heat exchanger, produce 50～160 ℃ hot compressed air;
B, hot compressed air is mixed at the mixing nozzle place through pipeline with feed liquid, after-applied on smoked sheet through nozzle atomization.
Another object of the present invention is achieved in that
Comprise heat exchanger and control device thereof; Compressed air, steam are delivered to heat exchanger through the PI control valve respectively; The temperature signal that temperature testing equipment detects steam road and compressed air road respectively is transferred to Programmable Logic Controller, Programmable Logic Controller with these data with send control signal after setup parameter is compared to the PI control valve; Be that thermal source is delivered to mixing nozzle and mixes with feed liquid with the hot compressed air, be transported to atomising device.
The present invention adopts heat-exchange device through steam compressed air to be carried out exchange heat, and to feeding device stable hot compressed air being provided is thermal source, and having overcome prior art is the too high tobacco process quality issue of bringing of thermal source moisture with steam.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further described, but never in any form the present invention is limited.
Fig. 1 is a prior art feeding device structural representation;
Fig. 2 is a feeding device structural representation of the present invention.
Among the figure: 1-charging (feeding) equipment, 2-mixing nozzle, 3-mass flowmenter, 4-centrifugal pump, 5-butterfly valve, 6-heat exchanger, 7-PI control valve, 8-temperature testing equipment, 9-Programmable Logic Controller PLC.
The specific embodiment
Fig. 1 shows prior art feeding device structure, is thermal source with steam and is delivered to mixing nozzle and mixes with feed liquid.
Fig. 2 shows feeding device structure of the present invention.
Tobacco charging technology of the present invention comprises following operation:
A, to be that thermal source heats compressed air with steam, promptly steam and compressed air carry out exchange heat through heat exchanger, produce 50～160 ℃ hot compressed air;
B, hot compressed air is mixed at the mixing nozzle place through pipeline with feed liquid, after-applied on smoked sheet through nozzle atomization.
Feeding device of the present invention comprises heat exchanger 6 and control device thereof; Compressed air, steam are delivered to heat exchanger 6 through the PI control valve respectively; The temperature signal that temperature testing equipment 8 detects steam road and compressed air road respectively is transferred to Programmable Logic Controller 9, Programmable Logic Controller 9 with these data with send control signal after setup parameter is compared to PI control valve 7; Be that thermal source is delivered to mixing nozzle and mixes with feed liquid with the hot compressed air, be transported to atomising device.
The course of work of the present invention:
By the power center (PC) delivering vapor to heat exchanger; Compressed air is implemented heat exchange; Heating back compressed air carries out temperature detection by temperature testing equipment 8; The temperature signal that detects is transferred to Programmable Logic Controller, and Programmable Logic Controller PLC sends control signal and arrives PI control valve 7 after the temperature parameter of temperature signal and setting is compared; Steam flow is regulated, reached set temperature value, accomplish closed-loop control compressed air temperature with the control compressed air temperature.Compressed air after the heating mixes at the mixing nozzle place through pipeline with feed liquid, and nozzle atomization is after-applied on smoked sheet, effectively controls the moisture of reinforced back smoked sheet, guarantees the crudy of smoked sheet.
Characteristics of the present invention:
1, owing to can regulate control to compressed-air actuated temperature; Spray temperature to feed liquid also can be regulated control accordingly in 50～160 ℃ of scopes; Can select the suitable temperature that applies to different feed liquids; Guarantee the complete of its chemical composition,, reach the purpose of improving the quality of products to create the suitable environment that feed liquid is had an effect to tobacco leaf.
2, owing to adopt hot compressed air that feed liquid is applied; Solved the problem that saturated vapor condenses easily; Hot compressed air can not produce the condensed water packing phenomenon, has solved the too high problem of stub bar moisture of production material, can not cause the waste of raw material and the fluctuation of crudy.
3, because the water content of hot compressed air own is very low, the moisture content of smoked sheet not have influence basically, just can well control tobacco leaf moisture content, prove through field data, feeding in raw material afterwards, the control accuracy of smoked sheet moisture content is ± 0.5%.
Effect comparison:
In big production, get one batch of (1750kg) full formula leaf group tobacco leaf by the processing of feeding in raw material of traditional charging (feeding) equipment, as control samples; Get one batch of (1750kg) full formula leaf group tobacco leaf again by transforming the processing of feeding in raw material of back charging (feeding) equipment; As test appearance; With control samples and test appearance store under the equal treatment conditions, chopping, drying, mix join dry-ice expanding silk, stem after perfuming; Store, roll into and carry out chemical composition behind the cigarette finished product and the aesthetic quality analyzes
