vacuum pump in vacuum humidity control

With the application of vacuum pump more and more, what is the function of vacuum pump in different fields? This time, we will give you a detailed understanding of the application of vacuum pump in vacuum humidity control. Vacuum humidity control: natural fiber (such as silk), man-made fiber, tobacco, paper and other products need to adjust their water content (mainly to increase its moisture), so that its water content is uniform and constant. Why choose to use vacuum pump in tobacco industry? What are the specific characteristics of vacuum pump?

First of all, let’s introduce the steps of vacuum humidification.

Vacuum humidity control steps:

1. Through water vapor;

2. Hot water is injected into the separator;

3. Steam and water are mixed and injected through the separator. The humidity regulation of wires is usually vacuum dried and cooled after water or steam injection to regulate humidity evenly and moderately.

At present, in our tobacco industry, water ring vacuum pump is used in tobacco vacuum resurgence. The disadvantage of water ring vacuum pump is that the vacuum degree is low, and the moisture regain cycle is not easy to reciprocate under the appropriate recovery temperature. For example, if the recovery temperature rises, the quality of tobacco leaves will be destroyed.

Later, the rotary vane vacuum pump was used in tobacco factory, which improved the vacuum degree of treatment and the quality of recovery. The recovery of moisture in the vacuum moisture regain cylinder mainly depends on the cigarette box under vacuum condition. After the steam in the cylinder is released, there is a pressure difference between the inside and outside of the cigarette package, and there is a temperature difference between the steam and the tobacco leaf. The higher the vacuum in the cylinder, the steam is released. The greater the pressure inside and outside the cigarette package, the higher the amount of steam entering the cigarette package. The temperature difference between the leaves of the steam flue is large, the steam is easy to condense, and the vaporization heat is released at the same time, which makes the temperature of tobacco leaf and the temperature of cigarette package rise. It is conducive to moisture absorption, so as to achieve rapid and uniform recovery.

rotary vane vacuum pump performance :

1, high limit vacuum degree, less than 0.5 mbar

2. High pumping speed, easy to use

3. Low working noise, less than 62 dB

4. Strong steam extraction capacity

5. Environmental protection. The pump is equipped with an oil mist eliminator, which can remove 99.99% of the oil in the exhaust gas

6. Compact structure, scientific and reasonable design, light weight, easy to install in industrial system

The working process of vacuum pump, transmission mode is often a very important part, so every friend also attaches great importance to these problems. From the perspective of the overall transmission mode, we can also notice that the characteristics in the actual work process are often very prominent, so I hope we can better grasp these characteristics, so that people can find a better answer.

When paying attention to the transmission mode of vacuum pump, it can be noticed that the overall pumping speed is proportional to the pressure range, and the two should achieve a more coordinated effect in each part. From the point of view of the whole wheel, it can be noted that the equipment is often very good in terms of wheel geometric symmetry, so it is very stable in the operation process, the overall fault sound is also very low, and the noise range is lower.
