Embodiment 1

[0016] Embodiment 1: The process standard of air drying outlet material moisture content is 12.6 ± 1.0%, the air flow drying inlet material flow rate is 3045kg / h, the air drying inlet material moisture content is 35.87%, the outlet material moisture content is 12.37%, and the moisture content is lower than The process standard requires the central value, and the drying control program automatically calculates and adjusts the airflow drying inlet material flow rate, and adjusts the inlet material flow rate to 3055kg / h. After the flow rate is adjusted, the airflow drying outlet material moisture content is 12.59%.

Embodiment 2

[0017] Embodiment 2: The process standard of air drying outlet material moisture content is 12.6 ± 1.0%, the air flow drying inlet material flow rate is 2977kg / h, the air drying inlet material moisture content is 36.0%, the outlet material moisture content is 12.84%, and the moisture content is higher than The process standard requires the central value, and the drying control program automatically calculates and adjusts the airflow drying inlet material flow rate, and adjusts the inlet material flow rate to 2949kg / h. After the flow rate is adjusted, the airflow drying outlet material moisture content is 12.54%.

Abstract

The invention discloses a method for controlling the moisture content of materials at the outlet of airflow drying. The detection point of the moisture content of materials at the outlet of airflow drying is set on the electronic scale after the airflow drying and sent by the air, and at the same time, a The metering tube controls the thickness of the material on the electronic scale, so that the detection value of the moisture meter is consistent with the moisture content of the material at the outlet of the airflow drying, and the control accuracy of the moisture content of the material in the airflow drying process is increased.

Description

technical field [0001] The invention relates to a method for controlling the moisture content of the material at the airflow drying outlet of a tobacco manufacturing enterprise, in particular to a control method for the moisture content of the material at the airflow drying outlet. Background technique [0002] The control and adjustment of the moisture content of the airflow drying outlet material is realized by automatically adjusting the flow rate of the airflow drying inlet material through the drying program control. After the moisture content of the material is detected by the moisture meter at the drying inlet and the moisture meter at the drying outlet, the moisture content data is transmitted to the drying control program. Calculate, automatically adjust the flow rate of the airflow drying inlet material, and realize the adjustment of the moisture content of the outlet material through the adjustment of the material flow rate. The existing technology is that the dete...
