• In the wort filtering process, the system automatically senses the underpressure under the sieve and controls the suction speed of the pump to prevent malt spent grains from being squeezed on the sieve – preventing sieve clogging.
• In the wort cooling process, the system automatically regulates the wort flow rate across the plate heat exchanger to achieve a constant desired wort temperature at the cooler outlet to the fermenters.
• The centrifugal pump is equipped with an induction flow meter connected to the PLC.
• Pneumatic valves are fitted to the water inlet and steam inlet in the brewhouse, they can be operated from the touch screen.
• A pulse flowmeter is installed at the water inlet of the brewhouse.
