[0002] In the production process of liquid milk and dairy products, many types of processing aids or nutritional enhancers are used, some of which are heat-sensitive substances. Due to their specific biological and chemical functions, heat treatment will destroy their structures. It will cause it to lose its activity, thereby losing its nutritional value or auxiliary function, and heat treatment is a necessary process in the production process of liquid milk dairy products. Only after heat treatment can it achieve the sterilization effect. Therefore, from this aspect, heat treatment limits the Application of thermosensitive substances in liquid milk dairy products
[0003] Based on the above reasons, this type of heat-sensitive substance needs to be prepared as a sterile substance before it can be added aseptically (the aseptic heat-sensitive substance is quantitatively added to the milk in the pipeline after the UHT sterilizer); in addition, there are some heat-sensitive substances Although the substance is sterile, it is a powder substance and cannot be directly used for aseptic post-addition (the aseptic post-addition process is useless for solid powder substances and can only be used to add liquid substances). Heat-sensitive substances can only be added aseptically after being prepared into liquid state substances, and are used in the production of liquid milk dairy products
[0004] However, the parameters required for sterilization and filtration of various heat-sensitive substances are different, including: pressure, type of filter membrane, filtration speed, etc. Therefore, if the matching of equipment in industrial production does not meet the requirements of the substance If the various parameters are carried out, there will be problems, which is not conducive to expanding the use range of heat-sensitive substances

Embodiment Construction
[0026] The test equipment for determining the parameters of heat-sensitive substance membrane filtration sterilization according to the present invention will be described below with a specific example.
[0027] Such as figure 1 As shown, the equipment includes two parts: a pre-filter part and a sterilizing part, and the pre-filter part includes a three-stage filter device, which is mainly used for impurity removal and pre-sterilization of the solution to make the product more pure, according to different substances The nature and its cleanliness can reduce the pre-filtration process, and at the same time, the sample filtered by the upper-level equipment can be taken out from each sample barrel to test the turbidity of the sample and the biological activity of the product, verify the impurity removal effect of the filter membrane and prevent the filter membrane from The effect on the activity of the sample, which can monitor each level of filtration, select the appropriate fil...

The invention relates to test equipment for determining membrane filtering sterilizing parameters of heat-sensitive substances. The test equipment comprises a plurality of stages of sample barrels and filtering units which are arranged in series; the filtering unit in each stage is arranged between the sample barrel in the stage and the sample barrel in the next stage; a non-return valve is arranged between the filtering unit in each stage and the sample barrel in the next stage; and the sample barrel is connected with a high-pressure sterile air pipe through a filtering pressure-reducing valve. The plurality of stages of filtering units which are arranged in series are of two stages; the first stage of filtering unit is used for impurity removal and pre-sterilization; and the second stage of filtering unit is used for final sterilization. High-pressure sterile air in the high-pressure sterile air pipe is in a pressure range of 1-20 bar. The test equipment disclosed by the invention is beneficial to studying sterilizing parameters and properties of various heat-sensitive substances, and can provide strong evidence for matching of equipment in industrial production, and reduce procurement risk of the equipment.
