Moisture chain control method for tobacco shred manufacturing process

Abstract

A moisture chain control method for a tobacco shred manufacturing process includes two synchronous steps of adjustment based on moisture fluctuation of blended stems and shreds and adjustment based on moisture fluctuation of tobacco shreds at an HT (humidifying tunnel) inlet. Detection to moisture of stems and shreds before the stems and the shreds are blended is added, moisture of an HT joint and moisture of a stem and shred blending joint are detected, when the HT inlet tobacco shred moisture and stem and shred moisture in the two joints are abnormal, key parameters of other relevant work procedures at joints in front and rear of the two joints on a tobacco shred processing chain are quantitatively adjusted, effective front and rear feedback is realized, stability of shred blending moisture after the stems and the shreds are blended is guaranteed, and stability of technological parameters of a shred drying procedure is ensured.

Description

technical field [0001] The invention relates to a water chain control method in the leaf silk making process. Background technique [0002] The process of making shredded tobacco, that is, the process of processing the raw materials of threshing, redrying and aging tobacco into finished shredded tobacco for rolling, is the main link of cigarette processing. In this process, the loose and rehydrated formula tobacco raw materials are sequentially fed, stored, shredded, HT rehydrated, and dried, and blended with auxiliary raw materials such as stem shreds to form mixed shreds, which are flavored and stored. Rolling process. The moisture control of materials in the silk making process is the key to ensure the stability of the moisture in the finished cut tobacco after blending, and then to ensure the quality of product rolling. [0003] In the leaf line blending process, the moisture stability of the output mixed silk is affected by the moisture of auxiliary raw materials such...

Problems solved by technology

However, at the blending point of shredded leaves and shredded stems, there is no material moisture detection and control measures

The problem existing in the current moisture control process of the leaf line is that since the shredded stems are mostly dried in a fluidized bed at present, compared with the shredded leaves, the moisture uniformity is poor, and there is a certain deviation in the input moisture of the shredded stems in the blending process. Even when the fluctuation is large, although the water content of the leaf silk remains relatively stable, it will still cause a certain deviation in the water content of the mixed silk after blending, which will affect the rolling process.

[0004]On the other hand, during the processing and circulation of materials on the leaf line, the moisture in each process link will affect the indicators and parameters of the upper and lower processes. Fully consider the interaction of moisture control factors between different processes. Each process adopts a relatively independent moisture control method. When the moisture of cut tobacco at the entrance of HT is abnormal, only by adjusting the key parameters in the drying process, although it can stabilize the cut tobacco at the outlet of the cut tobacco. However, since the drying process is a key process that affects the sensory and flavor quality of shredded leaves, the adjustment range of parameters in the shredded shredded process is too large, which may easily lead to unstable flavor absorption quality of shredded leaves after drying
