Description

Technical Field

[0001] The present application relates to the field of BBB technology, and in particular to a sterilization device for concentrated juice production. Background Art

[0002] The sterilization of fruit juice beverages requires killing pathogenic bacteria and spoilage bacteria in the juice and destroying the enzymes in the juice, so that the juice has a certain shelf life under a specific environment. At present, high-temperature sterilizers are often used to heat and sterilize concentrated juice. The juice is quickly heated and sterilized in the heating section of the high-temperature sterilizer, and then cooled in the cooling section.

Although the above-mentioned prior art solution has the beneficial effect of improving the utilization rate of heat energy by passing the high-temperature heating pipe through the preheating pipe and using the residual heat of the high-temperature beverage in the heating pipe to preheat the unsterilized beverage, it still has the following defects;

The contact time between the juice and the cooling tube is insufficient, and it is difficult to achieve uniform cooling, which affects the quality and texture of the juice.

[0005] In view of this, we propose a sterilization device for concentrated juice production. Utility Model Content

When the juice enters the cooling tank 5 through the heating tube 4, it can flow to the spiral channel formed by the multiple groups of guide plates 8. The multiple groups of guide plates 8 are spirally designed from inside to outside to disperse and guide the juice entering the cooling tank 5, so that the juice is distributed from inside to outside, so as to fully contact with the upper surface of the heat conducting plate 7, and fully cooled by the U-shaped first cooling tube 10, thereby increasing the cooling area of ​​the juice;

[0029] It is worth mentioning that drainage channels 9 are provided on both sides of the heat conduction plate 7, and the other end of the first cooling pipe 10 is connected to the second cooling pipe 12, and the second cooling pipe 12 is S-shaped. The second cooling pipe 12 is located below the drainage channel 9, and the other end of the second cooling pipe 12 is connected to the circulation pipe 13, and the other end of the circulation pipe 13 passes through the cooling tank 5 and extends to the outside of the sterilizer 1.
