Reliable leakage monitoring in the Hallertau, Germany

 

When producing the Germans' favourite drink - beer - hops from the world-famous Hallertau hop-growing region are a must. Along with barley malt, yeast and water, hops are one of the 4 ingredients permitted by the German Purity Law for brewing beer.

 

Hops season and preserve the beer in a natural way. And to ensure that there are no fluctuations in the quality of the beer, the hop refinement process standardises the bitterness of the hops. The hops also keep longer and retain their full, naturally fresh aroma.

About 45 kg of hop pellets are produced from 100 kg of raw hops. Hop refinement makes transport much easier and allows better storage and freshness.

Refinement takes place after the hop harvest. During this process, the hop cone is freed from heavy material and metal. The purified mass is pulverized by means of a cutting mill and homogenised again in mixers with a capacity of approx. 3 tons, and afterwards dried in hordes.

 

Finally, the powder reaches the pellet press where it is processed into hop pellets with the help of rollers and matrices and dried again. During the drying process CO2 is added, which is subject to permanent monitoring. This is achieved by using CO2 gas warning systems from MSR-Electronic.

 

CO2 gas warning systems from MSR-Electronic

 

The alternating sensor (type SC2 and type MC2) protects people and plant by continuously monitoring the ambient air for gases and vapors thanks to:

  • digitized measured value processing

  • temperature compensation
  • self-monitoring

The sensors include:

  • sensor element with infrared sensor
  • measuring amplifier
  • μController for measured value processing

The IR measuring principle ensures highest accuracy, selectivity and reliability despite long calibration intervals.

All data and measured values of the sensor element are stored in the μController in a fail-safe way and are transmitted digitally via the local bus to the sensor board SB2 or MSB2. Calibration management is also integrated in the μController of the sensor.

Calibration is done either by simply replacing the sensor cartridge or by using the comfortable, integrated calibration routine directly at the system.

The DGC-06 Digital Gas Controller from MSR-Electronic is the central unit for the entire gas monitoring in the drying process of hop refinement - a measuring, warning and controlling device system for toxic and combustible gases.

The DGC-06 Digital Gas Controller has been developed for large systems or even for extensive connections, e.g.:

 

The DGC-06 gas controller series is designed according to EN 50545 and can monitor and evaluate up to 128 gas sensors, 96 of which are digital and/or 32 analog sensors (4–20 mA).

Each sensor has 4 freely adjustable alarm thresholds. For alarm messages, the controller system has up to 128 relays with potential-free change-over contact and up to 16 analog outputs with 4–20 mA signal.
