Sterilizing machines for bottling

This is a fast process and it is expected that the bottles will be filled with the same amount of liquid. For the most part, these machines operate continuously 24 hours a day, seven days a week.

Bottles are directed to the taps by a conveyor belt and filled. Machine downtime is minimized.

Since these liquids are food products, it is important to comply with strict requirements, including machine sterilization. The filling machine taps are cleaned several times a day. To eliminate bacteria, the taps are rinsed with a sterilizing agent at a certain pressure and temperature ratio for 20 minutes. 

Specially designed by KELLER, the pressure sensors 25Zio monitor the temperature and pressure of the sterilizing agent. If the pressure or temperature does not meet the specified tolerances, sterilization is not guaranteed. An alarm is triggered and the rinsing process is repeated.

The equipment components used in the food industry meet special requirements, and KELLER's Zio line pressure sensors are no exception. The washing membrane in the 25Zio model ensures easy cleaning. Food residues do not stick to the thread because the thread does not come into contact with the measured medium. Food-grade sealing rings are used to seal the transmitter, and the sensors are filled with oil that does not pose a health hazard. If the membrane bursts and oil enters the liquid filling the bottles, it will still be safe for consumption.

Previously, the 25Y series used a built-in temperature sensor for this purpose, which required two input modules and two controllers. The Zio line makes this unnecessary as it is equipped with an IO-Link interface. One 25Zio monitors each filling tap, and the measurement data is transmitted via cable to the IO-Link device and from there to the controller.

IO-Link offers additional advantages:

• interference-free data transmission
• reliable communication system
• integration into existing systems
• connection of other interfaces via gateways
• communication protocol
• harmonization and simplification of smart networks
• automatic sensor ID verification
