Tobacco shred feeding treatment device and method capable of improving the heat energy and feed liquid absorption efficiency of tobacco shred

Abstract

The invention relates to a tobacco shred feeding treatment device and method capable of improving the heat energy and feed liquid absorption efficiency of tobacco shred. The tobacco shred feeding treatment device mainly comprises a tobacco shred feeding machine, wherein the tobacco shred feeding machine comprises a process circulating warm-air pipe, a roller, a power blower, a steam nozzle and an air inlet pipe; process circulating warm air is blown into the roller from the air inlet pipe via the steam nozzle under the action of the power blower to be mixed with the tobacco shred; the air inlet pipe is arranged under the central axis of the roller; the opening of the air inlet pipe faces up, and the included angle between the air inlet pipe and the horizontal plane is adjustable within 0-60 degrees. Under the premise that no heating and humidifying equipment is configured, the tobacco shred feeding treatment device can enable the process circulating warm air with steam to be contacted with the tobacco shred fully to improve the heat energy and feed liquid absorption efficiency and ensure the feed liquid absorption efficiency and uniformity of the tobacco shred.

Description

technical field [0001] The invention relates to the field of tobacco electric automation control, in particular to a shredded tobacco feeding and processing device and method for improving the heat absorption efficiency of shredded tobacco and the efficiency of feed liquid. Background technique [0002] At present, in the production process of shredded cigarettes, the processing technology of shredded tobacco has been applied in more and more cigarette production lines in recent years. figure 1 Shown is the structural schematic diagram of existing shredded tobacco feeding treatment device; figure 1 As shown, the shredded tobacco feeding processing device comprises a shredded tobacco feeder, a vibrating tank 1' and a warming and humidifying device 2', and the vibrating tank 1' and the warming and humidifying device 2' are sequentially arranged at the feeding end of the shredded tobacco feeding machine ( figure 1 The shredded tobacco feeder right end shown in ), the shredded ...

AI Technical Summary

Problems solved by technology

[0005] 1. The process circulating hot air A' with steam is blown in at the upper position of the central axis of the drum 4', and can only contact the shredded tobacco on the surface of shredded shredded tobacco falling from top to bottom, and the contact area with shredded shredded tobacco is small, so it cannot fully contact The shredded tobacco in the inner layer performs heat exchange, and the shredded tobacco has poor absorption effect on the feed liquid

In order to ensure that the shredded tobacco reaches the required process temperature and moisture content, it is necessary to increase the amount of steam injection, which will easily cause uneven moisture and temperature of the shredded tobacco

At the same time, the process circulating hot air with steam and material liquid is directly discharged to the end of the drum 4' without fully contacting and absorbing the shredded tobacco in the drum 4', most of which are discharged by the moisture removal system, which causes energy and material liquid waste

[0006] 2. When the saturated steam after hydrophobicity enters the process circulation hot air pipe and mixes with the hot air at about 80°C, a large amount of condensed water will be generated. Condensed water is generated, and when the condensed water enters the feeder, it will directly contact the shredded tobacco, resulting in the generation of wet lumps and water-stained tobacco, which is not conducive to the processing of subsequent processes and affects the quality of shredded tobacco

[0007] 3. The front end needs to be equipped with heating and humidifying equipment 2', and the heating and humidifying equipment 2' is a silk-making equipment with high energy consumption and serious environmental pollution, and its daily cleaning and maintenance workload is heavy
