Overview
Vacuum odor removal equipment is widely used in the tobacco industry and food packaging printing materials. The tobacco industry is organizing the implementation of industry standards for limiting volatile organic compounds (V0Cs) in cigarette strips and packaging paper. For a long time, the volatile odor substances generated in cigarette packaging paper printing have not been effectively controlled, and there is a significant gap compared to well-known foreign brands. If used for packaging food, it will directly contaminate the food. Affects the health of consumers. Based on this, Dachang Air Conditioning Equipment Company has collaborated with tobacco printing professionals to design and use vacuum (negative pressure) method to remove odors according to the requirements of printing technology. This is a new technology to solve the solvent residue and various odor limit indicators in cigarette strips and packaging paper. Proven by users, it can significantly improve production efficiency and product quality. This set of equipment has a large daily processing capacity, easy operation, and reliable operation, making it an ideal supporting equipment for cigarette label printing enterprises.
Principle
1. The product (printed matter) is placed in a vacuum chamber and evacuated with a vacuum pump. As the pressure inside the chamber decreases, the volatile odor substances in the printed material on the paper accelerate their evaporation. Under the pressure difference, they leave the surface and diffuse into space with the molecules that have already evaporated and attached to the surface, and are then discharged to the outside by the vacuum pump. Due to the tight overlap between the overlapping papers, the diffusion of odor molecules in the middle is not smooth, requiring a certain amount of time. The pumping time is proportional to the paper area and stacking thickness. The water loss of deaerated paper is inversely proportional to pressure and directly proportional to time. After three years of use by users, it has been proven that the equipment meets the design requirements and achieves ideal results. It can complete the odor removal work in 2-3 hours.
2. The vacuum deodorizer keeps the product in a vacuum dynamic pressure state, and the odor substances in the product quickly detach from the adsorption surface under the fluctuating pressure difference, and are discharged to the outside by the vacuum pump, thus achieving the effect of deodorization. The vacuum deodorization machine deodorizes quickly and uniformly, significantly reducing the deodorization time compared to traditional methods, greatly improving production efficiency and product quality.
Scope of application
The vacuum deodorizer is suitable for quickly removing various volatile organic compounds such as benzene, toluene, formaldehyde, ethylbenzene, butanone, etc. contained in cigarette label paper, food packaging paper, tableware, artificial boards, furniture, etc. The implementation of the "Limit Index for Volatile Organic Compounds (VOCs) in Cigarette Strips and Paper Packaging Materials" standard in the cigarette label printing industry has played an important supporting role.
