Heat Exchangers for Breweries: Wort Cooling and Heat Recovery

Breweries rely on plate heat exchangers because they cool hot wort rapidly, recover energy efficiently and meet hygienic standards. The compact, high-efficiency plate design hits the close temperature approach needed to chill wort to pitching temperature in a single pass, while the serviceable, gasketed construction allows full cleaning and inspection.

The classic brewery duty is the wort cooler (heat exchanger), which drops boiled wort from around 95–100 °C to pitching temperature (8–20 °C depending on yeast). A two-stage plate unit uses cooling water in the first stage — recovering heat into hot liquor for the next brew — and glycol or chilled water in the second stage for final cooling. Fast, hygienic cooling protects flavour and reduces contamination risk.

The heat removed from wort is recovered into a hot liquor tank rather than wasted, cutting energy use for the next mash. A well-designed wort cooler recovers a large share of the boil energy, making heat recovery one of the biggest efficiency levers in a brewhouse.

Brewery exchangers are built in 316L stainless steel with food-grade EPDM gaskets and are designed for clean-in-place (CIP). Smooth flow paths, full drainability and the ability to open the plate pack for inspection are essential to meet hygiene standards and avoid off-flavours from biofilm.

Shanghai Jiangxing supplies hygienic gasketed plate heat exchangers for wort cooling, CIP heating and energy recovery, in 316L with food-grade gaskets and CIP-ready construction.
