Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of sterilization equipment, and particularly relates to a UV sterilization system applied to fruit juice. BACKGROUND

[0002] Traditionally, fruit juice beverages commonly used are divided into pasteurization, high-temperature short-time sterilization method and ultra-high temperature instantaneous sterilization method. The so-called pasteurization is a low-temperature long-time sterilization method, the sterilization temperature is lower than 100 DEG C, and the holding time is 30 min. The high-temperature short-time sterilization method (HTST) is generally below 100 DEG C, such as the HTST sterilization temperature of milk is 85 DEG C, and is maintained for more than 15 s. The ultra-high temperature instantaneous sterilization method (UHT) is above 120 DEG C, and is maintained for only a few seconds. The two sterilization methods can effectively control the total number of microorganisms in the beverage, but the two sterilization methods change the color and taste of the fruit juice to some extent, and many nutritional components in the fruit juice, such as various phenolic antioxidants in natural fruits, are lost in large quantities. Ultraviolet sterilization is a high-efficiency low-energy sterilization method, which has been widely used in beverage and medical raw water sterilization. However, due to the deep color of fruit juice and sugar syrup, the ultraviolet transmittance is not high, and the relative application technology is difficult. The specific problems are as follows: the ultraviolet transmittance of fruit juice is very poor (such as tomato juice, orange juice, grape juice, etc.), and in order to achieve 99.99% sterilization, the ultraviolet must penetrate the fruit juice, otherwise there will be a blind area, and the sterilization is not complete.
