As seen from Table 1, " doing head " has obvious reduction with " dried tail " amount, illustrates that the cut-tobacco drier humidifying device has reached intended purposes.
The applicant has also carried out the discussion of others to the relevant technologies problem, make following explanation at this.To note after adopting humidifying device:
1. the wet pipe tobacco of anti-sealing
Increase humidifying device and make steam directly enter baking silk tube 4 contact with pipe tobacco, if the steam water content is too high or the humidification pipeline in water is arranged, water will enter baking thread tins 4, just might cause the water pipe tobacco that wets.For being very difficult for this to happen, on the one hand, it is moisture that the design of humidifying device steam pipework has steam-water separator 13 to be used to remove steam; On the other hand, designing again behind the gas force open type membrane valve 14 that control steam sprays has a gas force closed type membrane valve 16, is used for controlling the condensed water that the discharge line entrained steam produces, and makes it enter trench 17; Two valves are controlled with one road compressed air, because the valve body type selecting is opposite, form the anti-duty of one open-one close automatically.That is: add logical compressed air of the time of tide, gas force open type membrane valve 14 is opened, and gas force closed type membrane valve 16 closes, and steam is entered in the drying cylinder 4 by hot air duct 3.Disconnect compressed air during ordinary production, gas force open type membrane valve 14 closes at this moment, and gas force closed type membrane valve 16 is opened, and condensed water flows into trenches 17 by gas force closed type membrane valve 16 in the pipeline, avoids influencing operate as normal.
2. prevent to influence normal moisture control, the high-moisture pipe tobacco occurs
Because reducing the major measure of " doing head " and " dried tail " amount is decreasing temperature and increasing humidity, if control improperly, overlong time or amount of humidification are excessive, are easy to influence normal moisture control, cause outlet material moisture excessive.At first, we need determine suitable steam pressure., comprehensively relatively and through processing quality department approve same trade mark test according to repeatedly, determine to carry out the humidification processing with the steam pressure of 0.4Mpa.Following table is different steam pressure humidification test effects:
Different steam pressure over-dried cut tobaccos measure takes temperature
The trade mark | Supplied materials moisture (%) | Steam pressure (MPa) | A pipe tobacco amount (KG) of doing | Dried tail pipe tobacco amount (KG) | Moisture content of outlet (%) |
Dragon is risen in nine divisions of China in remote antiquity | 19.2 | 0.1 | 42 | 63 | <11 |
Dragon is risen in nine divisions of China in remote antiquity | 19.4 | 0.2 | 35 | 45 | <11 |
Dragon is risen in nine divisions of China in remote antiquity | 19.1 | 0.3 | 26 | 37 | <11 |
Dragon is risen in nine divisions of China in remote antiquity | 19.2 | 0.4 | 20 | 32 | <11 |
Dragon is risen in nine divisions of China in remote antiquity | 19.2 | 0.5 | 20 | 30 | <11 |
Secondly, the time of cooling and humidification through overtesting decision time started and concluding time, prevents that the excessive situation of moisture content of outlet from just often appearring in mass flow when must be noted that " doing head " processing on the one hand; Must be noted that " dried tail " processing time on the other hand, begin to lower the temperature and time of humidification, prevent to move and cause the excessive situation of moisture content of outlet too early.
In addition, the size of control humidification quantity of steam is particularly important.Theoretically, the humidification quantity of steam should be a changing value, and quantity of steam should be from big to small when " do head " handled, otherwise quantity of steam should be from small to large when " dried tail " handled.In the actual tests, grasp the time that steam sprays, adopting fixedly, emitted dose also can obtain good effect.But be noted that maximum steam emitted dose will consider capacity of equipment, the ability of particularly humidity discharging dust pelletizing system prevents from the humidity discharging dust pelletizing system is impacted, and influences ordinary production.
