Method for drying shredded tobacco and device for predicting moisture content of outlet shredded tobacco

Abstract

The invention belongs to the field of tobacco manufacturing, and relates to a method for drying cut tobacco, comprising the following steps: obtaining a prediction factor, where the prediction factor includes a preset moisture content of finished tobacco, real-time measurement data of temperature and humidity at a production site, and moisture content of blended cut tobacco; The factors are input into the prediction model to obtain the predicted value of the moisture content of the cut tobacco at the outlet of the dried cut tobacco process; the process parameters of the dried cut tobacco process are adjusted according to the predicted value of the moisture content of the cut tobacco at the exit of the dried cut tobacco process; wherein, the prediction model is based on the historical production of multiple batches of finished cut tobacco. Data establishment, historical production data includes moisture content of finished cut tobacco, historical measurement data of temperature and humidity at the production site, moisture content of blended cut tobacco and moisture content of cut tobacco at the outlet of the drying cut tobacco process. The invention also relates to a device for predicting the moisture content of cut tobacco at the outlet of the drying cut tobacco process. The method of the invention controls the moisture content of the cut tobacco at the outlet of the drying cut tobacco process, so that the moisture content of the finished cut tobacco reaches the design value and remains stable, thereby ensuring the stable quality of the cigarette.

Description

technical field [0001] The invention belongs to the field of tobacco manufacturing, and in particular relates to a method for drying shredded tobacco, and also relates to a device for predicting the moisture content of shredded tobacco at the outlet of the drying shredded tobacco process. Background technique [0002] The moisture content of finished shredded tobacco is directly related to the smoking taste of cigarettes and the physical and chemical quality of cigarettes. It is an important index parameter for cigarette manufacturing. The moisture content of different batches of finished shredded tobacco is unstable and often leads to large differences in the quality of different batches of cigarettes. Therefore, the moisture content of finished cut tobacco should be kept as stable as possible to maintain the quality of cigarettes. [0003] Usually, the production of finished shredded tobacco mainly includes the following processes: cutting shredded tobacco→drying shredded ...

Problems solved by technology

However, this method of empirical adjustment will always bring large errors, resulting in that the moisture content of each batch of finished tobacco can not be kept stable and does not meet the design requirements, thus affecting the stability of cigarette quality
