Problems solved by technology

In the traditional tobacco processing process, mixed materials such as dried leaf shreds, stem shreds, flake shreds, and expanded shreds form mixed shreds. The design ratio is applied. Since the formula design ratio is a certain value, the actual material liquid application ratio can only be corrected within a small range (the correction ratio is less than 5% of the formula design ratio), and the flow rate of the mixed filament fluctuates greatly, so the material liquid The flow fluctuates greatly, which affects the stability of the internal quality of the product

Embodiment Construction

[0017] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0018] Such as figure 1 Shown, a kind of flow control method that is used for flavoring liquid in the tobacco processing technology of the present invention comprises:

[0019] Step 1, measuring and collecting the instantaneous flow information of the mixed filament within a predetermined period of time with a fixed collection cycle. Specifically, when the system is running, the mixed yarn passes through the metering type flavoring main scale, so as to obtain the instantaneous flow information of the mixed yarn. In this embodiment, the instantaneous flow information of the mixed filaments can be stored in a FIFO queue of size n in chronological order, denoted as M t+0 , M t+1 ..., M t+n-1 . And the data of the instantaneous flow information of the mixed wire is updated according to the collection period. Generally, the collectio...

Abstract

The invention discloses a flow control method for adding spice liquid in the tobacco processing technology. The method comprises the steps that first, instantaneous flow information of mixed filaments is measured and collected in a fixed collecting cycle within a preset time period; second, a programmable controller is used for processing the instantaneous flow information obtained in the step one to obtain moving average information of the mixed filaments and feeding the moving average information back to a spice-liquid-adding flow controller; third, the spice-liquid-adding flow controller is used for controlling flow of added spice liquid according to the moving average information and a preset spice liquid adding formula proportion in the processing technology. The method can effectively lower fluctuation of flow of the added spice liquid caused by too large fluctuation of the instantaneous flow of the mixed filaments, achieve accurate control over flow of the added spice liquid, and improve stability of inner quality of products.

Description

technical field [0001] The invention relates to an industrial control method, in particular to a flow control method for flavoring liquid used in tobacco processing technology. The invention also relates to a flow control system for flavoring liquid in tobacco processing technology. Background technique [0002] In the process of tobacco processing, tobacco flavoring is a process of evenly spraying a prepared spice solution in shredded tobacco. Adding appropriate spices to shredded tobacco can enhance the original beautiful smoke flavor of the tobacco leaf formula, eliminate miscellaneous odors, make up for the lack of or insufficient aroma in the product, and make the smoke aroma of the product more rich and mellow. For the flavoring process, the prepared spices should be accurately and evenly applied to the mixed filaments according to the requirements of product design, that is, when the spices are applied, the flow rate of the material liquid should be stable. In the t...
