Temperature control method for barrel body of cut-tobacco drier

Abstract

The invention discloses a temperature control method for a barrel body of a cut-tobacco drier. The temperature control method includes the steps of: establishing mathematical models of flow rates of cut-tobaccos, moisture contents of incoming materials, increase of the moisture contents, the moisture contents at exit and standard work dewatering quantity, calculating corresponding relationship between the flow rates of the cut-tobaccos and different moisture contents of the incoming materials under the premise of keeping work pressures of HT steam, temperatures of the cut-tobacco drying barrelbody and temperatures of cut-tobacco hot wind to be constant and setting the increase of the moisture contents, the moisture contents at exit and the standard work dewatering quantity as preset constant quantities, and using a cut-tobacco flow rate calculation value as a set value after adjustment of parameters of the drier. The temperature control method has the advantages that the accurate flowrates corresponding to different moisture contents of the incoming materials can be quickly determined, and accuracy and reliability of adjustment are achieved; the operation is simple and applicable, and head materials can be adjusted in one time usually after entering the cut-tobacco drying barrel body; and the temperature of the barrel body can achieve control of "constant temperature" in order to ensure stability of quality within and between batches and consistency of processing intensity, and the method has a far-reaching significance to the stability of cigarette sensory quality and isworth popularizing and applying.

Description

technical field [0001] The invention belongs to the technical field of silk making in the tobacco industry, and in particular relates to a method for controlling the cylinder body temperature of a KLD-2 silk dryer during the silk making process. Background technique [0002] In the tobacco industry, the shred drying process, as a key process of shredded tobacco, has always attracted the attention of enterprises. How to produce shredded tobacco with stable quality has been a long-term research issue for enterprises. [0003] In the long-term production process of enterprises, each factory has its own experience and methods, but the uncertainty of the moisture content of incoming raw materials for drying silk is a common problem for all enterprises. [0004] Due to the long process of silk drying, the difference in the accuracy of feeding control in the previous process, the change of production environment, the inconsistent residence time of tobacco leaves in the storage room...

AI Technical Summary

Problems solved by technology

[0006] One is the lag in adjustment, which can only be adjusted after the shredded tobacco is delivered to the outlet of the shredded shreds and the moisture meter shows stability;

[0007] The second is that the adjustment accuracy is not high, and it often needs to adjust the flow rate several times to meet the control of the cylinder temperature;
