Description

A food packaging disinfection device

Technical Field

The utility model belongs to the field of food processing, and more specifically relates to a disinfection device for food outer packaging.

Background Art

Food packaging bags are easily contaminated by bacteria, and safety issues have always been a concern of consumers. During the production and transportation of outer packaging, there is a risk of infection by bacteria or viruses. If the outer packaging that has not been disinfected is directly transported or flows into the market after packaging, it is not conducive to ensuring the safety and quality of the product. If the outer packaging is not disinfected, viruses and bacteria will be brought directly into daily life, affecting people's health. Therefore, a solution is needed to disinfect independent outer packaging bags to avoid the risk of infection and prevent viral and bacterial infections. Existing disinfection operations generally adopt the form of manual spraying, that is, spraying disinfectant on the outer packaging of food by manually using a sprayer. This disinfection method has a large workload, low efficiency, and there are blind spots for disinfection. In addition, there is also the problem of environmental pollution caused by the splashing of disinfectant, so it needs to be improved.

At present, the patent with announcement number CN214824666U discloses a disinfection device for food outer packaging, including a gas cylinder and a conveyor table supported on a bracket, wherein the conveyor table includes a conveyor belt and an inclined slide connected to the input end of the conveyor belt; a disinfection chamber is arranged on the conveyor table; the conveyor belt is a mesh belt; both ends of the disinfection chamber are open, and the disinfection chamber is at least partially arranged on the conveyor belt; the top and both sides of the disinfection chamber are provided with nozzles facing the inside thereof; the lower end of the mesh belt is provided with a disinfectant receiving tank; the bottom end of the disinfectant receiving tank is connected to a filter tank, and a filter screen is arranged at the upper inlet of the filter tank; the filter tank is connected to each nozzle through a pipeline; the gas cylinder is connected to each nozzle through a pipeline.

However, a common problem with the outer packaging disinfection device in the prior art is that the food outer packaging disinfection device in the prior art can only disinfect the food outer packaging bags on the conveyor belt below through the nozzle fixed at the top of the disinfection cabinet. Because the bottom of the packaging bag is in contact with the conveyor belt, it is difficult for the packaging bag to fully contact with the disinfectant, resulting in the inability to disinfect the bottom of the outer packaging, resulting in the bottom of the packaging bag not being well sprayed with the disinfectant, and the disinfection efficiency is low. Therefore, further improvements are needed.

The advantages of this solution are at least that the collection or storage tanks provided in the disinfection devices of the prior art are mostly square and rectangular structures. Since the bottom surface of the tank is horizontal, the disinfectant flowing from the conveyor belt into the tank can generally only form hydraulic pressure by accumulating to a certain amount, and finally flow into the next place from the filter port. The utility model adopts an inverted trapezoidal structure of the collection tank, which can make the disinfectant quickly form hydraulic pressure when flowing from the conveyor belt to the collection tank and flow into the discharge port, greatly improving the flow speed and ensuring that a series of equipment behind the discharge port can operate normally.

The utility model is further configured as follows: the conveyor belt is mesh-shaped.

The advantages of this solution are at least that: the utility model adopts a mesh conveyor belt, which can prevent excessive retention of disinfectant on the conveyor belt and reduce the phenomenon of excessive loss of disinfectant. On the other hand, it can cooperate well with the collection tank. When the disinfectant falls on the mesh conveyor belt, it will reduce the time it stays on the conveyor belt and quickly flow into the collection tank, forming a large amount of rapid drainage, ensuring the full operation of a series of subsequent equipment.

In summary, the utility model has at least the following advantages:
