Spray mist generating device

Abstract

The invention discloses a spray mist generating device. The spray mist generating device comprises an atomization container device, hydrogen peroxide temporary storage devices and a pipeline system. When the spray mist generating device works, external compressed air enters the hydrogen peroxide temporary storage devices so as to push hydrogen peroxide out and feed the hydrogen peroxide into the atomization container device, and the hydrogen peroxide passes through a hollow-cone nozzle in the atomization container device to form mist-like air flow and is sprayed out; in another pipeline, external sterile air is fed into an atomization container through pressure from the bottom of the atomization container device, the sterile air is closely mixed with the mist-like air flow generated by thehydrogen peroxide to form uniform spray mist, and the spray mist is output from the top of the atomization container to the parts which need to be sterilized through pipelines. The spray mist generating device has the advantages that the spray mist generating device generates the spray mist composed of the sterile air and the peroxide, the spray mist has a powerful and efficient sterilization anddisinfection capacity, less condensate water is generated, the pipeline structure is simple, and the generated condensate water is drained through a pipeline.

Description

technical field [0001] The invention belongs to the technical field of liquid food sterilization, and particularly designs a spray generating device capable of high-efficiency sterilization. Background technique [0002] Most dairy products, milk, beverages and other liquid foods are filled by aseptic cold filling process, and the filling needs to be operated in a sterile environment. Sterilize PET bottles, cups or lids before filling. Among the existing sterilization technology schemes, one is to use the traditional wet method of sterilization—peracetic acid (PAA) sterilization, peracetic acid is a widely used high-efficiency disinfectant with strong bactericidal ability, and has a strong oxidation effect , can quickly kill all kinds of microorganisms, including viruses, bacteria, fungi and spores. However, peracetic acid can only be used for the sterilization of non-heat-resistant packaging materials, and it is not suitable for bottles and cups that require higher steril...

AI Technical Summary

Problems solved by technology

[0003] 1. The existing atomization container device has no heating function inside itself, hydrogen peroxide cannot be fully atomized, and more condensed water is generated in the atomization container device, which affects the sterilization effect;

[0004] 2. An atomization container device is equipped with a hydrogen peroxide buffer container device, and the flow supply in the pipeline is not timely, which affects the spray efficiency;

[0005] 3. Pump the hydrogen peroxide from the hydrogen peroxide buffer container into the atomization container device, the structure of the pipeline is complicated and the cost is high;
