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

Abstract

The invention belongs to the field of tobacco manufacturing and relates to a method for drying cut tobacco. The method comprises the following steps: acquiring predictive factors, wherein the predictive factors comprise preset moisture content of finished cut tobacco, real-time determined data of temperature and humidity in production places and moisture content of blended cut tobacco; inputting the predictive factors into a prediction model so as to obtain a predicted value of the moisture content of the outlet cut tobacco in a cut tobacco drying process; and adjusting process parameters of the cut tobacco drying process according to the predicted value of the moisture content of the outlet cut tobacco in the cut tobacco drying process, wherein the prediction model is established according to historical production data of the finished cut tobacco of multiple batches, and the historical production data comprises the moisture content of the finished cut tobacco, historical determined data of the temperature and humidity in production places, the moisture content of the blended cut tobacco and moisture content of the outlet cut tobacco in the cut tobacco drying process. The inventionfurther relates to a device for predicting moisture content of outlet cut tobacco in the cut tobacco drying process. According to the method disclosed by the invention, the moisture content of the outlet cut tobacco in the cut tobacco drying process is controlled, so that the moisture content of the finished cut tobacco reaches a design value and is kept stable, and the stable cigarette quality is further ensured.

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
