Wort cooling, monitoring of process and plate heat exchanger
Wort cooling, monitoring of process and plate heat exchanger
What is measured and for what reason:
Temperature: Is the main parameter to monitor and to control the process. Pressure: Is used to increase the performance. Rising pressure difference between in and outlet indicates a build up on the plate, that need to be cleaned then. Flow: Is used for process control. Data recording: Is used to save the important quality relevant process data, but also to monitor alarm points in flow and temperature.Why is it special:
Hot wort is coming in with temperatures about 100°C. This means thermal stress. The other end is cold wort between 8 and 14°C which has a very high need for hygienic installations. The differential pressures that need to be detected are very small. Temperature, as well of the wort, but also of the cooling media needs to be monitored. The wort temperature affects the fermentation.How can it be solved best:
Temperature: a PT100 is recommended. Pressure: beside very fast hydrostatic, also normal hydrostatic measurement are good solutions. Flow: electromagnetic is the solution. Depending on hot or cold side use, the standard or the Endress + Hauser Promag 50 H sensor is the favorite. Data recording: Endress + Hauser Memograph is the ideal choice or heating or cooling systems. Recording all needed data with including alarm point signals.Voor meer informatie: Endress+Hauser GmbH
