Example Embodiment

[0035] Example 1:

[0036] In a typical implementation of the present application, a method for stabilizing the processing strength of a tumble dryer is disclosed. The mathematical model used is:

[0037] The water loss model of each section before and after moisture, Y1=X1-X2×Z+X3×N1+X4×N2, Y2=X5+X6×N3-X7×N4, among which; Y1 is the water loss in the section from the outlet of moistening leaves to the inlet of drying silk , Y2 is the water loss from the drying silk outlet to the mixed silk section, Z is the storage time after moisturizing the leaves, N1 is the water loss point Y1 ambient temperature, N2 is the water loss point Y1 ambient humidity, N3 is the water loss point Y2 ambient temperature, N4 Water loss point Y2 ambient humidity, X1, X2, X3, X4, X5, X6, X7 are brand coefficient constants, which can be set according to the situation of the previous month or the same period of the previous year, specifically: the previous month or the same period in history as the unit, colle...

[0040] Example 2:

[0041] A system for stabilizing the processing intensity of a drum-type silk dryer, including a dynamic prediction system for the processing intensity of the drying silk, a dynamic prediction system for the processing intensity of the drying silk, communicates with a measurement system and a production control system. The measurement system is an environmental temperature and humidity acquisition module and Historical data analysis module;

[0042] Further, the environmental temperature and humidity acquisition module simulates the distribution of the internal environmental temperature and humidity in the production workshop, and preferably uses a height of 1.5±0.3m as the installation plane, combined with the process route in which the moisture content loss occurs, and selects that can characterize the temperature and humidity changes in the area The area is the installation point. Finally, through the data fusion of the drying silk processing intensity dynamic...

[0045] Example 3:

[0046] Taking a certain brand of cigarettes as an example, the analysis is carried out in units of the same period in history. Collect the water loss value and water loss point environmental temperature and humidity values ​​of all batches from November 1 to 30, 2017, and perform regression analysis to determine the mathematical model, Y1=-0.365-0.006*leaf storage time+0.059*internal temperature -0.006*internal humidity; Y2= 1.192+0.005*internal temperature -0.012*internal humidity.

[0047] After the model validity test, the water loss regression model is significant, the residual error and mean square test are normal, and finally the regression equation of the water loss point in November 2018 is obtained, and the regression equation is used to predict and control the outlet moisture of the moisturizing leaf:

[0048] Moisture at the outlet of the leaves Q1=standard central value of moisture content of mixed silk Q3+Y2+target value of brand drying dehydration+Y...

Abstract

The invention discloses a method and a system for stabilizing the processing strength of a drum-type cut tobacco dryer. The invention discloses the method and system for stabilizing the processing strength of a drum-type cut-tobacco dryer, which belong to the technical field of tobacco control, and comprise the following steps: a mathematical model of the processing strength of the cut-tobacco dryer and moisture loss of cut-tobacco processing is established, and a dynamic prediction system of the processing strength of the cut-tobacco dryer is established based on the mathematical model; before production procedures of tobacco leaf moistening and feeding, the processing strength dynamic prediction system automatically predicts moisture loss of each subsequent procedure section according tothe mathematical model, adjusts and sets moisture at an outlet of the tobacco leaf moistening and processing procedure, and stabilizes the dehydration amount of the cut-tobacco dryer so as to stabilize the processing strength of the cut-tobacco dryer; when a cut tobacco drying process begins, the processing strength dynamic prediction system performs cut tobacco drying outlet moisture correctionaccording to a correction model by collecting the actual value of the cut tobacco drying inlet moisture so as to stabilize the mean value of the batch-to-batch dehydration amount of the cut tobacco drying process, greatly reduce the batch-to-batch fluctuation range of the dehydration amount of the drum-type cut tobacco dryer and stabilize the product processing strength.

Description

technical field [0001] The invention belongs to the technical field of tobacco control, and more specifically relates to a method and a system for stabilizing the processing strength of a drum-type silk drying machine. Background technique [0002] Under the existing equipment conditions, no matter how the control mode of the drum silk dryer changes, the dehydration amount of the silk dryer is used as a comprehensive indicator of the impact of the cylinder wall temperature, hot air volume, and hot air temperature, and its change represents the fluctuation of product processing intensity. In the conventional way, the moisture at the outlet of the leaf moistening and feeding process is controlled through human experience to stabilize the moisture of the subsequent raw silk, that is, the moisture at the inlet of the silk dryer, thereby ensuring the stability of the processing strength of the drum silk dryer. [0003] However, the inventors found that due to the large time span ...
