Material regain moisture device and method

Abstract

The invention discloses a material moisture regimen device and method, and relates to the field of tobacco machinery for improving the resistance workability of expanded tobacco, reducing the amount of expanded tobacco shredding and sticky wall, and improving the physical quality of the expanded tobacco. The material moisture regaining device comprises a cooling belt, moisture regaining parts and a drum type moisture regaining device. The cooling belt, the moisture regaining parts and the drum type moisture regaining device are in turn adjacent. The moisture regaining parts and the drum type moisture regaining device are provided with spray components for material moisture regaining. The material moisture regain device is capable of performing step-by-step moisture regaining, and a repressive medium added in each step is fully absorbed into the inside of the tobacco in a maximum. The material moisture regain device has the advantages of improving the control precision of the moisture content of the expanded tobacco to make the moisture content more uniform after the moisture regaining, reducing the amount of the tobacco shredding, the moisture tobacco, and stick wall, and greatly improving the resistance workability of the expanded tobacco and the physical quality of the finished tobacco.

Description

technical field [0001] The invention relates to the field of tobacco machinery, in particular to a device and method for moisture regaining of materials. Background technique [0002] Expanded shredded tobacco is an important part of cigarette raw materials, and it is a powerful tool for reducing tar and harm of cigarette products and reducing cigarette production costs. Adding expanded shredded tobacco in the cigarette production process is conducive to improving the filling capacity of shredded tobacco, reducing the amount of tar released from cigarettes, and improving smoking safety; at the same time, it can improve the use grade of medium and low-grade tobacco leaves and reduce the cost of cigarettes, so expanded shredded tobacco is widely used in the cigarette production process . [0003] At present, the production process of domestic expanded shredded tobacco is basically the same, that is, shredded tobacco is impregnated at the cold end and expanded at the hot end (...

AI Technical Summary

Problems solved by technology

Since the expanded shredded tobacco needs to increase the moisture content of the expanded shredded tobacco by 5% to 8% in the drum, a large amount of rehydration medium is applied; at the same time, the entire humidifying device is in the drum of the drum type dampening machine, and the moisture balance time of the expanded shredded tobacco is short, which cannot be achieved in a short period of time. Time is absorbed by the expanded shredded tobacco, resulting in high humidity in the drum, a large amount of shredded tobacco sticking to the wall of the drum and a large amount of wet smoke; in addition, the moisture content uniformity of the expanded shredded tobacco is poor, which seriously affects the product quality, and the water spray device in the drum is seriously hanging , there are problems such as poor processing resistance of expanded shredded tobacco, high crushing rate, and low finished shredded shred rate
