Wort cooling with heat recovery
A brewery wort cooler is a heat-recovery opportunity as much as a cooling duty. A single- or two-stage plate heat exchanger cools hot wort to pitching temperature: the first stage recovers heat into brewing liquor sent to the hot-liquor tank (cutting energy for the next brew), and the second stage trims to pitching temperature against glycol or chilled water.
The design levers are the approach temperature on the recovery stage, the glycol supply temperature and the allowable pressure drop on the wort side (which is fouling-prone from trub and hop matter). DFT sizes the cooler for the recovery target and pitching temperature, integrates the glycol supply and specifies a plate pattern and gasket suited to wort duty and CIP.
