Method for improving tobacco shred preparing quality stability

Abstract

The invention provides a method for improving the tobacco shred preparing quality stability. The method specifically includes the steps of material putting, primary moisture regaining, stored leaf preparing, secondary moisture regaining, stored leaf distributing, shredding, moisture controlling, shred drying, mixing, flavoring and storing. The moisture controlling process is added after shredding,so the problems that due to the long process route, the material process water content is greatly influenced by the environment temperature and humidity and the shred drying inlet water content of different batches fluctuates obviously are solved, the incoming material water content of the shred drying process is stabilized, the stability of the water content of different batches of materials entering the shred drying process is ensured, the shred drying machine outlet material water content meets the processing requirement, and therefore the processing intensity and dewatering amount of theshred drying process of different batches are stabilized, and the stability of the sensory quality of shred drying outlet materials is ensured; compared with other methods, the method has the advantages of being small in technological change, small in refitting investment, capable of saving energy and reducing consumption and free of newly constructing or refitting of a factory.

Description

technical field [0001] The invention belongs to the field of cigarette shredded processing, and in particular relates to a method for improving the quality stability of shredded tobacco leaves. Background technique [0002] The existing process of shredded tobacco leaves is as follows: shredded tobacco is fed → first dampening → pre-mixed leaf storage → second dampening → blending and storing leaves → shredded → increasing temperature and humidity → drying shreds → blending → flavoring → storage is completed Silk making process. After shredding is completed, the raw silk enters the HT, and through the control of the steam pressure, the moisture and temperature of the raw silk drying inlet material are increased, thereby improving the filling capacity and processing resistance of the shredded leaf, so that it can meet the processing requirements of the silk drying process. However, the existing technology cannot realize the stability of the moisture content of the incoming t...

AI Technical Summary

Problems solved by technology

This method and the method disclosed in the previous patent both ensure the moisture content of the material entering the silk dryer by adjusting the HT intensity, but the change of the HT intensity leads to the sensory quality of the material before drying, and the sensory quality of the material at the outlet of the silk dryer between batches. The quality changes and cannot be adjusted in both directions

[0022] As proposed in the method disclosed in Chinese patent 200610140232.2, the finished cut stems are packed and covered, and then stored in a box-type leaf storage warehouse with constant temperature and humidity in the form of a conveyor or a three-dimensional warehouse. After feeding, it is blended into leaf silk through a quantitative control process, so that the moisture content of the material to be blended is stable and the blending accuracy is guaranteed; the disadvantage is that the amount of investment and equipment renovation is relatively large, and at the same time, it is necessary to renovate or build a factory building, and High energy consumption in industrial warehouses with constant temperature and humidity

In addition, due to the different hygroscopicity of different grades, the required storage environment temperature and humidity are also different, so there are limitations in the use of constant temperature and humidity industrial warehouses
