Problems solved by technology

However, due to the strong irritant of ozone, it will cause great harm to the human body, so it is subject to certain restrictions in terms of food sterilization.
The existing ozone sterilization device basically adopts a tank type or a box type device, and puts the items to be sterilized into a closed container for sterilization, and the efficiency is low

Embodiment Construction

[0011] A best embodiment of the present invention will now be described in detail in conjunction with the accompanying drawings.

[0012] Such as figure 1 As shown, a water-sealed ozone continuous sterilization device includes: an oxygen bottle 1, an ozone generator 2, an air-water mixing device 3, the air-water mixing device 3 adopts a Venturi tube, and one end of the ozone generator 2 is connected to the oxygen bottle 1 The other end is connected with the gas-water mixing device 3; the two ends of the ozone water tank 7 are provided with an isolation tank 6 outside the tank wall; baffles are installed at regular intervals on the conveyor belt 8, and the chain and the gear 9 drive system are driven to run. The guide wheels at both ends of the mesh belt 8 are below the water surface of the isolation tank 6, and the guide wheels in the middle are set above the ozone tank 7, so that the conveying mesh belt 8 enters the device through the isolation tank 6, passes through the ozon...

Abstract

The invention discloses a water-sealed ozonic continuous sterilization device, which comprises an oxygen cylinder, an ozonizer, an air and water mixing device, an ozonic flume, a conveyer belt mesh and an ozonic watering device. One end of the ozonizer is connected with the oxygen cylinder and the other end is connected with the air and water mixing device. An insulating flume is arranged outside the flume walls on both ends of the ozonic flume. Guide pulleys on both ends of the conveyer belt mesh are arranged below the water surface of the insulating flume and guide pulleys in the middle of the conveyer belt mesh are arranged above the ozonic flume; the ozonic watering device is arranged above the ozonic flume and the conveyer belt mesh and connected with the air and water mixing device through pipelines, the air and water mixing device is connected with the ozonic flume through pumps. The water-sealed design adopted in the invention enables the ozone gas or the ozone water to be insulated from the external environment so as to avoid the damage to human health by the ozone and achieves continuous sterilization operation through the mesh belt mechanical transmission device. The device is applicable to the sterilization of the food material containing more harmful microbes.

Description

technical field [0001] The invention relates to a water-sealed ozone continuous sterilization device, which belongs to the field of food processing. Background technique [0002] Many pickled vegetables and aquatic products themselves contain more harmful microorganisms, which affect the food safety of the products and the shelf life of the products. Preservatives are used to prolong the shelf life of products, but this will have adverse effects on the health of consumers; and the safer and more effective thermal sterilization measures will seriously affect the taste and quality of some products (such as radishes, etc.) . [0003] Ozone sterilization technology is one of the cold sterilization technologies used in the modern food industry. This technology has the characteristics of wide sterilization spectrum, simple operation, no residue and instant sterilization. It is an ideal new technology for sterilization. However, due to the strong irritant of ozone, it will cause ...
