Method and device for carrying drum-type drying and accurate processing of tobacco shred

Abstract

The invention discloses a method for drying tobacco shreds in a drum way and accurately processing the tobacco shreds. The discharging end of a drum cut-tobacco drier is provided with a pressure detector, firstly, corresponding drum wall temperature, hot air temperature T1, hot air amount N, and moisture removing opening M are set according to the processing characteristics of the cigarette, the preheating is started, and the tobacco shreds can be gone into production after the temperature in the drum reaches the set requirement; secondly, the tobacco shreds are gone into production, the steam consumption is tracked and regulated so as to enable the steam consumption to be quickly stabilized to the set requirement, material water W at a discharge port during the processing is on the low side and or the high side, the moisture removing opening M is quickly regulated and the change of internal pressure P is monitored, if the P value exceeds a certain limitation, the hot air amount N is tracked and regulated so as to enable the temperature of the drum wall to be stabilized to the requirement of the processing parameter of the product. The method can effectively improve the stability, the uniformity and the controllability of the drum drying processing of tobacco shreds, realizes the drying accurate processing of the tobacco shreds, and realizes that the device of the method has simple structure, convenient manufacture and reliable performance.

Description

technical field [0001] The invention relates to a method for processing shredded tobacco, in particular to a method for precisely processing shredded tobacco by drum drying, and also relates to a device for realizing the method. Background technique [0002] Shredded tobacco drying treatment is an essential link in the cigarette processing process, and its treatment effect is crucial to the sensory quality of cigarette products, especially the appropriate selection and stable control of the tube wall temperature. Improving the stability, uniformity and controllability of shredded tobacco drying is an urgent problem to be solved in the industry. [0003] As far as the drum type silk dryer is concerned, it can be divided into three sections in theory: front-end drying section, middle-end buffer section, and rear-end balance section. The distribution length of the drying section and the balance section determines the temperature of the cylinder wall used for drying. It also de...

AI Technical Summary

Problems solved by technology

The current control technology only controls the temperature of the cylinder wall, and there is no means of monitoring the air pressure inside the cylinder. Once the air intake and exhaust volume change, the temperature control of the cylinder wall is often unstable, resulting in changes in product quality.
