Description
Technical Field
The invention belongs to the technical field of auxiliary devices of vacuum moisture regaining machines in the tobacco industry, and particularly relates to a humidifying water supercharging device of a vacuum moisture regaining machine, which is used for increasing the moisture content of tobacco flakes subjected to vacuum moisture regaining.
Background
The tobacco leaf is a colloid capillary porous substance, and the water absorption function of the tobacco leaf is similar to that of a capillary porous body, and mainly comprises the adsorption function and the permeation function.
The moisture absorption process of the tobacco leaves is carried out by the surrounding medium, namely air. When dry tobacco leaves in the air meet the water vapor in the air, the water vapor is absorbed by the capillary porous bodies of the tobacco leaves to form non-combined water. On the other hand, the movement of moisture occurs due to the difference in partial pressure of water vapor in the tobacco leaves and the air. The water vapor permeates into the tobacco leaves to form combined moisture.
The humidifying of the tobacco leaves is mainly carried out by the following three ways: directly spraying moisture on the tobacco leaves; putting tobacco leaves in high-humidity water vapor; the method comprises the steps of directly spraying moisture on the tobacco leaves, and meanwhile, placing the tobacco leaves in high-humidity water vapor, mainly placing the tobacco leaves in the high-humidity water vapor.

Softened water used for vacuum moisture regaining is pressurized and supplied by a power part, the pressure is about 0.45MPa, but at the moment when a vacuum moisture regaining and humidifying water nozzle is opened, the humidifying water pressure is obviously reduced to about 0.3MPa due to the suction effect of a vacuum box body, so that the moisture absorbed by tobacco flakes in the box body is insufficient instantly, and the moisture of the tobacco flakes after moisture regaining is low. The moisture content of the tobacco flakes treated by the vacuum moisture regaining machine is low, the processing resistance is poor, the tobacco flakes are easy to be broken, and the raw material consumption is increased.
Based on the analysis, the moisture content of the tobacco leaves after moisture regain is low because the humidifying water pressure is obviously reduced to about 0.3MPa due to the suction effect of the vacuum box body at the moment when the vacuum moisture regain humidifying nozzle is opened, so that the moisture absorbed by the tobacco flakes in the box body is insufficient instantly, and the moisture of the tobacco flakes after moisture regain is low.
