Problems solved by technology
[0004] At present, there are many studies on adding necessary flavors, fragrances or humectants during the threshing and re-roasting process, such as the utility model patent "A System for Adding Materials and Fragrances to Threshing and Redrying" (publication number: CN203692512U), which adds The feeding nozzle and the flavoring nozzle of the aroma device are respectively located at the entrance of the drum feeder, which solves the problem that the traditional leaf threshing and re-roasting cannot be flavored, and the flavoring is uneven and inaccurate; the invention patent "a tobacco leaf alcoholizing agent And its application in the process of threshing and rebaking" (public number: CN100336476C) discloses that a certain amount of humectant is added in the threshing and rebaking stage, and the tobacco leaf alcoholizing agent is either added on the original tobacco leaves, or stored after threshing. In short, it is added in the leaf moistening cabinet. In short, it is added before rebaking. This patent adds humectant through threshing and rebaking, which improves the biological characteristics of tobacco leaves and significantly improves the smoking quality of cigarettes.
In the prior art, the spraying method is often used to re-roast and feed the tobacco leaves. This type of spraying method has the following disadvantages: low degree of automation, poor spraying uniformity, poor spraying effect, easy to cause waste of spraying liquid, and cannot be effective. Control the moisture content of the tobacco after filling

Embodiment Construction
[0028] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0029] Such as Figure 1-3 , the spraying device shown includes a plurality of dual-medium spray nozzles 17 arranged on both sides of the lamina blanking path and staggered or distributed along the laminar tobacco blanking path. The width of the laminar tobacco blanking path is relatively wide, which is beneficial to The material liquid is evenly attached to the tobacco leaves, which not only improves the uniformity and effect of spraying, but also reduces the waste of material liquid. Including a plurality of nozzles, the nozzles include a gas-material mixing chamber 29, one end of the gas-material mixing chamber is axially connected with a material-liquid nozzle 28, and the other end is closed, and the side walls on both sides of the gas-material mixing chamber are respectively connected with nozzle air inlets 26 and the nozzle inlet 27, the nozzle inlet is fed wi...

The invention discloses a spraying device, a spraying system and a spraying method for threshed and redried lamina. On one hand, a plurality of double-medium spray heads are arranged, so that the spraying uniformity and effect are improved. The waste of feed liquid is reduced. On the other hand, each double-medium spray head comprises a plurality of spray nozzles. Each nozzle comprises a gas-material mixing cavity and a feed liquid nozzle. The flow of the feed liquid nozzle can be accurately controlled by comprehensively regulating and controlling compressed air flowing into the gas-material mixing cavity and the flow and flow velocity of feed liquid. The spraying uniformity and effect are further improved. The moisture of the fed tobacco strips is effectively controlled. According to thespraying system, feeding and discharging of the feeding system are accurately controlled through the electric cabinet. The integrated accurate control is achieved. The reliable maintenance of the whole system can be achieved by arranging the cleaning unit. According to the spraying method, by strictly controlling the ratio of the spraying amount of the double-medium spray head to the material flowof the tobacco leaves, trace spraying in the true sense is achieved.
Description
technical field [0001] The invention relates to the technical field of tobacco processing, in particular to a spraying device, a spraying system and a spraying method for sheet tobacco after threshing and redrying. Background technique [0002] Leaf threshing and redrying is an indispensable and important link in the cigarette industry. It not only separates and redakes tobacco leaves and tobacco stems, but also plays an important role in the formulation and quality of shredded silk. [0003] Tobacco leaf rebaking and feeding is the process of threshing and rebaking production. The feed liquid is accurately and uniformly applied to the surface of the material, and is fully absorbed or adsorbed by the material, so as to play the role of the feed liquid in improving the quality defects of tobacco leaves and improve the raw material quality of tobacco leaves. use value. There are usually several ways to add ingredients during the threshing and redrying stage: 1. Add flavor, ad...
