Sterilization method of full-automatic ultra-high temperature sterilization machine

Abstract

The present invention relates to a technological process of full-automatic ultra-high temperature sterilization equipment. Said technological process includes the following steps: making material be passed through a balance tank, then be fed into tubular heat exchanger (P1.1), then making said material be passed through tubular heat exchangers (P1.2, P2, and P3), after its temperature is progressively raised, making said material be fed into tubular heat exchanger (P4) to make high-temperature sterilization; then making said material be fed into heat-insulating system to implement heat-insulating sterilization, then making said material be passed through tubular heat exchanger (H1) to make its temperature be reduced, and making said material be passed through a homogenizing machine and a tubular heat exchanger (I) so as to make temperature of said material be reduced to proper filling temperature, then making filling operation.

Description

technical field [0001] The invention relates to a milk product sterilization process, in particular to a process flow of a fully automatic ultra-high temperature sterilizer. Background technique [0002] Improving the physical fitness of the whole nation is an arduous process, and increasing the per capita consumption of milk is a key indicator. A glass of milk strengthens a nation. The ultra-high temperature sterilization process can make milk reach absolute sterility, and with the aseptic filling machine, the shelf life of milk can reach 6 months, which is one of the key technologies to popularize the consumption of milk. [0003] The advanced milk ultra-high temperature sterilization process is used to prolong the shelf life of milk and improve the problem of long-distance milk transportation. However, the existing domestic equipment cannot meet the requirements well. The main reasons are as follows: [0004] 1. Domestic equipment has poor sterility reliability. The des...

AI Technical Summary

Problems solved by technology

[0003] The advanced milk ultra-high temperature sterilization process is used to prolong the shelf life of milk and improve the problem of long-distance milk transportation. However, the existing domestic equipment cannot meet the requirements well. The main reasons are as follows:

[0004] 1. Domestic equipment has poor sterility reliability

The design of the sterilization process is unreasonable, and the aseptic reliability of the product cannot be completely guaranteed, and the product will deteriorate

[0005] 2. The degree of automation of the equipment does not meet the requirements, and it cannot be integrated with the degasser, vacuum flasher, and sterile homogenizer, and cannot realize intelligent control itself

[0006] 3. High energy consumption of equipment: heat utilization rate>=85%
