Sterilization treatment device for aseptic packaging system and sterilization treatment method

Abstract

The invention provides a sterilization treatment device for an aseptic packaging system. The device is characterized by comprising an aseptic chamber and an air filter device; air is filtered through an air filter device, and then is sent to the aseptic chamber with a sterilization groove; an atomizing nozzle and an ultraviolet lamp are arranged on the top in the aseptic chamber; the atomizing nozzle is connected with a hydrogen peroxide device; a packaging material is passed through the sterilization groove, and is sterilized by the ultraviolet lamp; a filling tube is partially arranged in the aseptic chamber; the top end of the filling tube is connected with a cleaning valve through a flow control valve; and one end of the cleaning valve is connected with a steam input device. The invention also provides a method by utilizing the device, which comprises the following steps: forming the aseptic chamber; forming aseptic air by an air filter method; and sterilizing the packaging material by the hydrogen peroxide and the ultraviolet ray. The device and the method cannot consume mass water resource or mass energy like heating and cooling, and the packaging material and mechanical parts are not easy to be destroyed at the same time.

Description

technical field [0001] The invention relates to a disinfection and sterilization treatment device and a disinfection and sterilization treatment method of a coiled cardboard bag-making aseptic packaging machine. Background technique [0002] In the food industry, the paper roll forming packaging system is currently the most widely used packaging system for aseptic packaging of commercial aseptic liquid foods such as fruit juices, beverages, and milk. The packaging material is continuously supplied to the packaging machine by paper rolls, and goes through a series of forming processes for filling, sealing and cutting. The material used for aseptic packaging is essentially a composite material, which is a multi-layered cardboard composed of paper, polyethylene, aluminum foil, and sarin resin. The paper is the structural material, and the aluminum foil is a high-barrier material. The aseptic packaging system of roll cardboard bags is most represented by the Tetra Pak aseptic p...

AI Technical Summary

Problems solved by technology

Therefore, the energy consumption is large

[0010] 2) Using sterile air at 120°C will easily cause defects such as blistering, brittleness, and fracture of the packaging material

At the same time, it is easy to cause the gap change of mechanical parts, causing problems such as mechanical jamming

[0011] 3) When the packaging machine uses the water ring compression pump to provide pressure air, it needs to use water as the sealing medium, resulting in a large consumption of water resources
