Pressure Transducers Keep Food Safe
High-pressure sterilizers are widely used as an alternative to heat sterilization in food and beverage products. Several of WIKA’s pressure transmitters are specifically designed for sanitary food and beverage applications for high-pressure sterilizers.
Heat sterilizers use steam to destroy pathogens that cause disease or food-borne illnesses without affecting the taste or nutrition of food products. On the other hand, high-pressure sterilizers use high-pressure hydraulic fluids, typically water, at moderate temperatures to sterilize food and beverage products. High-pressure sterilization is particularly effective with higher-acid-content foods such as juices and precooked meats. Low-acid foods like vegetables and milk cannot be fully sterilized using the high-pressure sterilization process.
High-pressure sterilization uses a pressure transducer in a sanitary pressure transmitter to monitor processes that ensure proper sterilization. The following WIKA pressure transmitters are designed for such applications:
A typical cycle of a sanitary pressure transmitter in a sterilization phase includes four steps
Temperature and pressure transducers are used to monitor the environmental conditions in the sterilization chamber. Pressure transducers monitor hydraulic fluid pressure inside the sterilization chamber along with the pressure output and control of the high-pressure water pump.
They are also used to monitor and control sterilization chamber pressure, in addition to monitoring and controlling water pump pressure.
The figure above is an example of a typical horizontal high-pressure sterilizer for food and beverage sanitation.
High-pressure sterilizers in sanitary applications call for pressure transducers that are compatible with high-pressure water and lower temperature ranges. Components used in high-pressure sterilization machinery typically meet FDA and USDA regulations for traditional high-temperature pasteurization and sterilization.
When selecting a sanitary pressure transmitter, it’s best to consider:
