Cargo size self-adaptive channel type plasma disinfecting and killing system

Abstract

The invention discloses a cargo sizeself-adaptive channel type plasma disinfecting and killing system, which comprises a disinfectiing and killing main channel and a disinfecting and killing channel support main body. The disinfecting and killing main channel is positioned above the disinfecting and killing channel support main body. Two ends of the disinfecting and killing main channel are connected with a goods inlet and a goods outlet respectively, and the goods inlet is provided with a goods inlet size recognition unit. A plasma injection array and / or a spraying unit and a cooling unit are / is arranged in the disinfecting and killing main channel, and the plasma injection array is connected with a high-voltage power supply. According to the cargo size self-adaptive channel type plasma disinfecting and killing system, an array plasma generator directly or indirectly acts on the physical surface and even permeates a certain depth, the surface of an object is rapidly and efficiently sterilized within 3-10 seconds, and rapid disinfecting and killing can be achieved; and meanwhile, article size identification can be realized through the goods inlet size recognition unit, the action space of the plasma is adjusted, and the action efficiency is improved.

Description

technical field [0001] The invention relates to an adaptive cargo size plasma channel type second-level sterilization system, which belongs to the technical field of sterilization. Background technique [0002] Channel sterilization is an efficient continuous sterilization process that kills microorganisms on products, packaging containers, packaging materials, packaging aids, packages or bulk goods, transport vehicles, and personnel, reducing them to the allowable range. . [0003] With the outbreak of the new coronavirus epidemic, people have found that the virus is obviously transmitted from person to person; especially cold chain foods, frequently tested positive on the outer packaging and surfaces. It poses a major threat to the health of the people and causes immeasurable losses to the economy. [0004] At present, the common disinfection method in the market is to use chemical disinfectant such as peracetic acid and 84 disinfectant; although the operation is simple ...

AI Technical Summary

Problems solved by technology

[0004] At present, the common disinfection method in the market is to use chemical disinfectant such as peracetic acid and 84 disinfectant; although the operation is simple and easy to kill germs more thoroughly, it will leave an odor after disinfection, and it is easy to leave chemical residues, which generally have Corrosive and Bleaching

[0005] The current spraying and killing technology discloses a spray sterilizer for beverage production with the application number of 201621394161.4, including a production line, a support frame and a liquid medicine mixing tank, etc. The hot water sprayed by the device is not uniform enough to spray the items, which affects the sterilization effect

[0006] In some food production processes, the commonly used sterilization equipment uses ozone and ultraviolet rays to achieve sterilization, but the sterilization effect is weak, and the bottom of the food cannot be exposed to ozone or ultraviolet rays, which is easy to be infected by bacteria, and the sterilization efficiency is low, especially in the assembly line. Due to the difficulty of sealing the goods in and out of the equipment, it is difficult to guarantee the concentration of the disinfecting factor, and it is generally necessary to work in an unmanned environment

[0007] Traditional plasma sterilization equipment has the advantages of fast killing speed and strong inactivation ability, but it also has a small working space, which is limited by the size and shape of items in the industrial sterilization process
