Problems solved by technology

Compressed air is mostly used to gently blow the moisture-discharging hood on the loose moisture regainer. Since the air source pressure of the compressed air is positive pressure, when the compressed air gently blows the hood, the area around the moisture-discharging hood will instantly become In the positive pressure area, since the negative pressure detection probe is installed near the moisture exhaust cover, the interference of lightly blowing compressed air will cause severe oscillation of the negative pressure control system, which will affect the normal work of the loose moisture regainer, and further cause Affects the quality of tobacco moisture regain

Embodiment Construction

[0015] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0016] Such as figure 1 As shown, the method for stabilizing the moisture regain pressure of the moisture conditioner includes the following steps: firstly, a negative pressure value is set, and the actual pressure in the drum of the loose moisture conditioner is detected by a pressure sensor and fed back to the controller. The opening degree keeps the pressure in the drum of the loose damp conditioner stable. When the tobacco leaves and powders adsorbed on the drum of the loose moisture conditioner affect the normal use of the loose moisture conditioner and need to be cleared by blowing with compressed air, the compressed air will be blown back and forth on the cylinder of the loose moisture conditioner through a blowing pipe. The light blowing method can minimize the impact of compressed air on the negative pressure in the drum of the loos...

Abstract

The invention discloses a method for stabilizing the dampening pressure of a dampening machine. When compressed air gently blows a roller of the loose dampening machine, the opening of a damp removing air door of the loose dampening machine is enlarged, positive pressure formed by the compressed air can be partially counteracted, negative pressure environments are maintained in the roller of the loose dampening machine, a negative pressure control system of the loose dampening machine cannot generate large vibration, normal operation of the loose dampening machine can be ensured, and the dampening quality of cut tobaccos is improved.

Description

technical field [0001] The invention relates to the field of cigarette production, in particular to a method for controlling the moisture regain pressure of a loose moisture conditioner. Background technique [0002] The loosening and dampening machine is one of the key main equipments on the tobacco silk making line. Its main function is to loosen the block tobacco slices cut by the slicing machine into tobacco leaves, and at the same time appropriately increase the temperature and moisture content of the tobacco leaves to provide a process for subsequent processing. condition. The dehumidification system is one of the important components of the loose moisture regaining equipment. Its main function is to maintain the stability of the internal pressure of the drum, form a certain negative pressure inside the drum, and at the same time discharge part of the water in the drum to keep the hot air in the drum Stable moisture content. The negative pressure control system of th...
