Method for controlling hot air temperature of drum type equipment used for tobacco sheet processing

Abstract

A hot air temp controlling method for the drum-type apparatus used to prepare tobacco sheets features that the constant sprayed steam quantity is used as reference and the steam in the heat exchanger is regulated to stably control the temp of hot air, resulting in high quality of tobacco shreds.

Description

technical field [0001] The invention relates to the technical field of tobacco processing equipment control, in particular to a method for controlling the hot air temperature of a drum type equipment in the process of processing tobacco leaves in cigarette processing. Background technique [0002] For the cigarette industry, the tobacco leaf treatment process on the silk production line is very important, which is related to the quality of cigarettes. Therefore, the control of the hot air temperature of the drum equipment used for tobacco leaf treatment naturally becomes the focus of technological research and production processing. Focus, the current hot air temperature control method for drum equipment used in the blade treatment process is generally: use a heat exchanger to provide a constant heat source, steam injection as a means of regulation, steam injection regulation is mainly through the steam film valve to control the amount of steam injected Realized, the steam m...

[0002] For the cigarette industry, the tobacco leaf treatment process on the silk production line is very important, which is related to the quality of cigarettes. Therefore, the control of the hot air temperature of the drum equipment used for tobacco leaf treatment naturally becomes the focus of technological research and production processing. Focus, the current hot air temperature control method for drum equipment used in the blade treatment process is generally: use a heat exchanger to provide a constant heat source, steam injection as a means of regulation, steam injection regulation is mainly through the steam film valve to control the amount of steam injected Realized, the steam membrane valve adopts a quick-response control method when controlling the hot air temperature, that is, when the hot air temperature is lower than the set value, the opening of the membrane valve is opened, and it lasts for a period of time until the hot air temperature rises to the set value and then closes. Repeat the same action back and forth, the temperature of the hot air fluctuates and presents ups and downs, which can easily affect the moisture of the tobacco leaves, thereby affecting the quality of the shredded tobacco
