Low-temperature aseptic system and process for filling plastic bottled drink

Abstract

The invention discloses a low-temperature aseptic system and a low-temperature aseptic process for filling plastic bottled drink, and belongs to the technical field of food processing. The system and the process are technically characterized in that: the heating sterilization adopts a countercurrent instantaneous heating sterilization device, and the device comprises a countercurrent heat exchange pipeline and an instantaneous heating sterilization pipeline; and a material is heated and sterilized in the instantaneous heating sterilization pipeline, the heated and sterilized material performs heat exchange and temperature reduction in the countercurrent heat exchange pipeline, the heating sterilization temperature is between 150 and 155 DEG C, the time is between 8 and 12 seconds, and the outlet temperature is between 25 and 30 DEG C. A countercurrent heat exchange structure and a countercurrent heat exchange process are adopted, so the system and the process have less heat loss and short heating time, avoid the high-temperature oxidation of the drink, effectively maintain nutritional components of finished products, and reduce the energy consumption. The system and the process adopt normal-temperature filling, have low filling temperature, effectively overcome the 'cooked soup taste' caused by high-temperature filling, and maintain the original flavor of tea and fruit juice. The system has the advantages of simple structure, steady operation and convenient maintenance.

Description

technical field [0001] The invention relates to a filling equipment and process, in particular to equipment and a process for aseptically filling plastic bottled concentrated tea drinks and fruit juice drinks, and belongs to the technical field of food processing. Background technique [0002] At present, plastic bottled beverages in the prior art, such as tea beverages and fruit juice beverages, generally adopt a high-temperature filling process above 85 degrees Celsius. During the filling process, the materials are in a high-temperature state for a long time, and the taste becomes poor and nutrients are easily lost; especially green tea. I am most afraid of being heated for a long time, which will easily produce a "cooked soup taste"; at the same time, the nutrients in the drink will also be damaged to varying degrees. Therefore, the high-temperature filling process cannot produce high-quality bottled tea and fruit beverages. In addition, high-temperature filling requires ...

AI Technical Summary

Problems solved by technology

[0005] Another object of the present invention is to provide a process for aseptically filling plastic bottled beverages at low temperature, so as to overcome the defects in the prior art that the high temperature filling is easy to produce cooked soup taste, poor taste and easy loss of nutrients.
