Material moisture content control system, drum-type cut tobacco dryer and material moisture content control method

Abstract

The invention discloses a material moisture content control system, a drum-type cut tobacco dryer and a material moisture content control method, which relates to the field of tobacco machinery, and are used for improving the accuracy of material moisture content control. The material moisture content control system comprises a roller, a temperature adjusting device, a humidity adjusting device, afeeding flow detecting device and a control device, wherein the roller has a feeding end, a discharging end and an inner cavity; the temperature adjusting device conveys process air into the roller through the feeding end or the discharging end of the roller; the humidity adjusting device is communicated with the inner cavity of the roller; the control device is in signal connection with the temperature adjusting device, the humidity adjusting device and the feeding flow detecting device; and the control device is constructed to control the temperature of process air conveyed into the rollerby the temperature adjusting device and the humidity of fluid conveyed into the roller by the humidity adjusting device according to the flow detected by the feeding flow detecting device. According to the material moisture content control system, the drum-type cut tobacco dryer and the material moisture content control method, the accuracy of material moisture content control is improved.

Description

technical field [0001] The invention relates to the field of tobacco machinery, in particular to a material moisture content control system, a drum type shred dryer and a material moisture content control method. Background technique [0002] Shredded drying is the core process of cigarette shreds, which is directly related to the sensory quality of cigarette products. It directly affects the style characteristics, shape, quality of the product, the agile response ability of the control of the production operation system, material consumption, energy consumption, etc. It is a key link to realize product value and improve product quality. At present, the mainstream equipment for drying silk is drum-type silk drying machine. [0003] In the related art, shredded tobacco enters the drum of the drum-type shred dryer from the feeding hood through the feeding vibrating groove, and the drum continuously rotates under the action of the transmission device. The shredded tobacco rol...

AI Technical Summary

Problems solved by technology

[0004] The inventor found that there are at least the following problems in the related art: the hot air entering the drum is the air in the equipment environment heated by the heater, and the humidity of the hot air is greatly affected by the natural environment, resulting in environmental changes and / or material flow changes The dehydration rate of the material is difficult to control, which eventually leads to poor control of the moisture content of the material
