Sterile preparation process based on sterile liquid beverage

Abstract

The invention relates to a sterile preparation process based on a sterile liquid beverage. The sterile preparation process comprises the following steps: carrying out ultraviolet sterilization on a raw and auxiliary material material bag, weighing and proportioning raw and auxiliary materials in the material bag by using a negative pressure weighing bin after the sterilization is finished to obtain a mixed material, carrying out online cleaning and online sterilization on a mixing tank, and after the cleaning and the sterilization are finished, putting the mixed material into the mixing tank for preparation to obtain a preparation solution, conveying the preparation solution with sterile compressed air to obtain a stock solution, in the process, carrying out integrity detection on filter elements of a first degerming-level filter and a second degerming-level filter by using a water immersion detection method, and according to a detection result, carrying out re-filtration treatment on a first stock solution which does not meet the condition during detection, and carrying out filtration pressure adjustment on the second stock solution which does not meet the condition during detection, and obtaining the sterile liquid beverage without using preservatives in the whole process. The resources are saved, the effective finished product of the sterile liquid beverage is kept, and no loss of nutritional ingredients of the sterile liquid beverage is ensured.

Description

technical field [0001] The invention relates to the field of food processing technology, in particular to an aseptic preparation technology based on aseptic liquid drinks. Background technique [0002] With the improvement of people's living standards, aseptic liquid drinks have become an indispensable daily drink for people to pursue a safe and healthy life. Sterility means the absence of viable bacteria and is an important concept in biotechnology. Only under the premise that the culture medium and fermentation equipment are sterile, after the microorganisms are inoculated, can pure culture be achieved, and the desired product can be finally obtained. The method of preventing microorganisms from entering the body or objects is called aseptic manipulation or aseptic technique. [0003] In order to obtain aseptic liquid drinks, the current preparation process in the industry is to sterilize the raw materials and auxiliary materials (such as preservatives) separately, and t...

Problems solved by technology

[0003] In order to obtain aseptic liquid drinks, the current preparation process in the industry is to sterilize the raw materials and auxiliary materials (such as preservatives) separately, and then mix them according to the required ratio in a sterile state, and fill them with filling equipment. The use of preservatives will cause a waste of resources, and will change the effective finished product of aseptic liquid drinks, resulting in the loss of its nutritional content
