PU value control system of intelligent sterilization machine

Abstract

The invention discloses a PU value control system of an intelligent sterilization machine. The system includes a user input module, a system input module, and a system management module. The user input module includes a parameter setting module which includes a bottle parameter setting module, a sterilization machine parameter setting module, an operation parameter setting module, and a technology parameter setting module. An input end of the parameter setting module is connected to a sensor module, a switch control module, and a human computer interface. An output end of the parameter setting module is connected to the system output module. The system output module includes a temperature output module, a PU value output module, an alarm display module, and an error reporting display module. The output end is connected to the system management module. The system management module includes a technology querying module, a data operation module, and a data management module. According to the invention, the system reduces fluctuation range of the PU value, guarantees stable sterilization effects in a maximum manner, and reduces energy consumption.

Description

technical field [0001] The invention relates to the field of control systems, in particular to a PU value control system for an intelligent sterilizer. Background technique [0002] Beer is a low-alcohol beverage brewed from wort by adding brewer’s yeast through fermentation. The existence of these yeasts and other bacteria and other microorganisms will directly affect the quality and shelf life of beer. Therefore, the brewed fresh beer Generally, sterilization treatment is required to ensure the biological stability and long-term preservation of the product. [0003] However, in the beer sterilization process, the beer is in a closed state, and the internal temperature cannot be accurately detected. We can only detect the temperature of the spray water. What about the actual temperature of the beer in the bottle? At the same time, in actual production, the sterilization time will also fluctuate with the efficiency of the assembly line, which further affects the temperature...

Problems solved by technology

[0003] However, in the beer sterilization process, the beer is in a closed state, and the internal temperature cannot be accurately detected. We can only detect the temperature of the spray water. What about the actual temperature of the beer in the bottle? At the same time, in actual production, the sterilization time will also fluctuate with the efficiency of the assembly line, which further affects the temperature of the beer in the bottle. Therefore, we currently use the temperature of the spray water, and calculate the temperature in the bottle based on statistical data. There is a large deviation between the theoretical PU value and the actual sterilization PU value, resulting in large fluctuations in the actual detected PU value

In order to ensure the effective killing of microorganisms, beer production enterprises will increase the minimum PU value, that is to say, the average PU value in actual production is much higher than the theoretical safe PU value for killing microorganisms. While losing the taste of beer, it will increase energy consumption and waste resource
