Air supply control system for cut tobacco dryers

Abstract

The invention discloses an air supply control system for cut tobacco dryers, which comprises a plurality of rows of air supply holes, a plurality of electric heating fans, a plurality of temperature detection units, a plurality of air quantity detection units, a plurality of rotation speed detection units, a plurality of air quantity regulation valves, a memory unit, a controller and a parameter-setting unit, the air supply holes are arranged from the front to the rear on the inner wall of the drying chamber of a controlled cut tobacco dryer, the electric heating fans are respectively connected with the air supply holes through a plurality of air supply pipes, the air quantity regulation valves are respectively mounted on the air supply pipes, multi-level standard air supply control parameters are stored in the memory unit, and the rotation speed and heating temperature of the electric heating fans and the opening degrees of the air quantity regulation valves are controlled by the controller according to the multi-level standard air supply control parameters. The air supply control system has the advantages of simple structure, high intelligentization degree and good using effect, is easy to operate, and can effectively solve the defects of the conventional air supply control system for cut tobacco dryers, such as single function, air supplier control only based on set control parameters, low intelligentization degree and poor drying effect.

Description

technical field [0001] The invention relates to an automatic control system, in particular to an air supply control system for a silk drying machine. Background technique [0002] The shred dryer is an important equipment in the production line of the shred workshop of the cigarette factory. Its main function is to ensure that the shredded tobacco at the outlet of the shredded drier reaches the moisture content that meets the requirements of the cigarette process, improve the shredded rate and filling value of the shredded tobacco, and change the physical properties of the shredded tobacco. Make the tobacco aroma mellow. The function of the air supply control system of the silk dryers used today is relatively single. It can only control the air supply device according to the preset air supply temperature, air supply volume and air supply speed, but it cannot be realized in the drying room by According to different control parameters from front to back, the shredded tobacco ...
