Description

Technical Field

[0001] The invention relates to the technical field of film material disinfection equipment, in particular to a film material surface disinfection device used in a packaging production line. Background Art

[0002] In the process of unpacking, installing the packaging machine and completing the packaging of ice products, the packaging film of the multi-channel packaging machine is affected by the operating procedures and the environment, and is contaminated by environmental microorganisms. In addition, since the plastic film is prone to generate static electricity and absorb dust particles in the environment during operation, it affects the food microbial safety and quality experience of the packaged ice products. In order to solve the above problems of packaging film, the current main disinfection methods are ultraviolet radiation disinfection and ozone disinfection.

[0003] There are two main methods of disinfection at present; Technical Solution 1: The conventional microbial control and disinfection method for the packaging film used in the current multi-channel packaging machine for ice products is to place it in the auxiliary material temporary storage room after unpacking, and perform static disinfection using ultraviolet rays and ozone.

[0004] Technical solution two is to install an ultraviolet lamp tube at the packaging film running position of the packaging machine, and the packaging film moving at high speed is exposed to UVC ultraviolet radiation when passing through the ultraviolet lamp tube.

[0005] The technical solutions currently used mainly have the following defects: For technical solution 1, static disinfection is carried out in the auxiliary material temporary storage room. This disinfection method can only effectively disinfect the exposed surface of the packaging film, but the inside of the packaging film roll cannot be disinfected synchronously. When the packaging film roll is transported to the packaging machine and installed, it will still be affected by the pollution of the environment and personnel operation; For technical solution 2, when the packaging film is in operation, the running speed is generally around 180mm / s. At such a fast speed, the irradiation dose of conventional UVC ultraviolet lamps cannot reach the dose required to disinfect microorganisms, and is thus useless.

The specific sterilization principle is as follows: the filtered air is transported to the plasma module 20 through the air duct 11. The plasma adopts the high-voltage discharge technology to form a local ionization zone, which can release high-concentration positive and negative oxygen ions and hydroxyl active particles. When the clean air passes through the ionization zone, it carries high-concentration positive and negative oxygen ions and hydroxyl active particles and is sprayed onto the inner surface of the packaging film, forming a layer of ion layer on the inner surface of the packaging film, and at the same time quickly kills the microorganisms attached to the surface.
