Why do cigarette factories use dehumidifiers?

The production process of cigarettes is very complicated. From tobacco procurement to finished cigarettes, multiple processes such as silk-making and packaging are required. At the end of each process, the quality of tobacco raw materials and cigarette products must be maintained.

Tobacco itself contains moisture. With the change of ambient temperature and humidity, moisture is affected by chemical reactions such as evaporation, absorption, and diffusion. When the humidity is high, the tobacco leaves absorb moisture, resulting in mildew and corruption, and the spread speed is accelerated, and the affected area is larger. However, the storage environment of tobacco leaves should not be too dry, as excessive drying will lead to loss of moisture in tobacco leaves, resulting in breakage, which affects the quality of cigarette production. Therefore, the temperature and humidity of cigarette production environments such as tobacco production workshops, cigarette packaging, and tobacco warehouses should be strictly controlled, and the following points should be done.

1. When storing tobacco leaves, it is generally required that the storage place be dry, closed and clean, free from direct sunlight, and not directly affected by changes in temperature and humidity. It can be waterproofed at the bottom and around the floor and can be stored more than 40 cm above the ground.

2. Tobacco leaves from different stoves and different parts should be stacked separately to facilitate classification and sales. When stacking, the tip of the leaf is inward, the base of the leaf is outward, and the layers are neat, and the tobacco leaves should be eliminated. After stacking, strictly cover with plastic film, linen, etc. to cover the sunshade layer, the height should not exceed 1.5 meters, and the length and width should be determined according to the actual situation.

3. Regular inspection. The temperature in the chimney should be controlled below 35℃. The temperature and moisture status of tobacco leaves are usually checked every 4-6 days. When the temperature exceeds 37 ℃, it should be turned over and cooled, and the tobacco leaves with too much moisture should be taken out in time.

Tobacco, finished cigarettes, tobacco products and other industry and national standards are specified in accordance with industry standards and industry standards and national standards such as "Design Specifications for Tobacco Raw Materials and Cigarette Finished Products", "Tobacco Storage and Preservation Methods", "Flavored Tobacco Packaging, Labeling and Storage" The temperature and humidity of cigarette products are 15℃~30℃, and the relative humidity is 55%≤65% to ensure that the products are not wet and dry.

Therefore, temperature control and humidity control are the conditions for tobacco storage, and it is not feasible to use traditional methods for precise control. It is necessary to install special temperature and humidity control equipment, commonly known as "dehumidifier", "constant temperature and humidity machine", and can It is called tobacco leaf dehumidifier, cigarette factory constant temperature and humidity machine, cigarette factory dehumidifier, etc.

The cigarette factory dehumidifier is composed of a compressor, a heat exchanger, a fan, a water tank, a casing and a controller. It belongs to the refrigeration and dehumidification equipment. Its working principle is that the fan pumps the moist air into the machine, and the water in the air is discharged through the heat exchanger. Molecules condense into water droplets, and the treated dry air is discharged from the machine to keep the indoor humidity at an appropriate relative humidity to ensure that tobacco products are not affected by air humidity during storage.
