The wort boiling is done either inside the wort pan (internal boiler) or externally with an external boiler, which can be designed as a tube bundle or plate heat exchanger. The boiling times per brew are between 50 and 75 minutes. Objectives of wort boiling:
- Adjusting the desired wort concentration
- Destruction of malt enzymes or fixation of wort composition
- Sterilization of the wort
- Protein coagulation
- Hop isomerization
- Aroma formation
- Evaporation of unwanted aroma substances
For quality and efficiency reasons, the wort concentration in the brewhouse must be continuously monitored.
LiquiSonic® Sound velocity measurement in the wort kettle
Application
The LiquiSonic® Plato system determines the original gravity at different stages of the brewing process. In the wort pan, it is LiquiSonic® Plato system used for:
- Control of the cooking process
- Determination of the concentration of the cast wort
The immersion sensor is made entirely of stainless steel and operates maintenance-free, drift-free, and long-term stable due to its robust construction. The integrated LiquiSonic® high-performance technology enables stable measurement even with gas bubble contents. Through the LiquiSonic® controller automatic product switching is possible. An internal limit monitoring signals exceedances and shortfalls and sends the real-time information via analog or digital outputs, serial interfaces, or fieldbus (Profibus DP, Modbus) to the process control system.
Installation
In the internal kettle, the sensor is mounted directly in the wort pan. The installation length is variable and can be up to 3 m. A special design of the sensor minimizes the influence of deposits. Additionally, the sensor in the internal kettle can be equipped with a cleaning head to avoid crusting from foam. When used in an external kettle, the sensor is mounted directly in the circulation line between the wort pump and heat exchanger. During the installation of the LiquiSonic® sensor no bypass is necessary and dead spaces are avoided.
The LiquiSonic® Controller 30 can be connected to up to 4 sensors. Additionally, up to 99 types of beer can be stored with the corresponding calculation models. This makes it possible to monitor multiple measuring points simultaneously.
Konzentrationsbereich: 0 °P bis 20 °P | Temperaturbereich: 40 °C bis 120 °C
Customer benefits
LiquiSonic®reduces time-consuming laboratory measurements and makes manual sampling unnecessary:
- Time required: 2 h per day
By continuously determining the knockout wort, the cooking time can be reduced.
LiquiSonic® Plato ensures a precise analysis of the original wort concentration with permanent data recording. The system is used in both internal and external boilers. Expensive bypass solutions are not necessary.
