Cooling and aeration of wort before the beer fermentation

Equipment intended to the cooling and aeration of wort before the beer fermentation

We use several different types of the wort cooling and aeration systems in our breweries : System devices, providing cooling of hot wort (an intermediate product produced by wort brew machine) to the desired fermentation temperature. Fermentation temperature depends on the type of beer and yeast type that is used for the beer fermentation process.

Wort is usualy cooled down with iced water or glycol solution which are pre-cooled and stored in the water cooling tanks. There the cooling of water and glycol takes place using the external or integrated cooling unit.

Main parts of all the wort cooling equipment are the plate heat exchanger, pipe aeration candle with stainless steel porous stone, temperature sensors and connection elements.

More about the wort cooling and aeration

What is wort cooling and aeration and why it is necessary in beer production?

What is the plate heat exchanger ?

A plate heat exchanger is a type of heat exchanger that uses metal plates to transfer heat between two fluids. This has a major advantage over a conventional heat exchanger in that the fluids are exposed to a much larger surface area because the fluids are spread out over the plates.

What is the aeration the wort ?

After the wort brew process is very important to cool the wort rapidly to below 26°C (80°F) to prevent oxidation, and then to aerate it to provide the dissolved oxygen that the yeast need in start of the wort fermentation process. Cooling rapidly is important because this temperature region is ideal for bacterial growth to establish itself in the wort. The aeration of the wort is ensured with the porous stone which saturated cooled wort with sterile air during pumping the wort from the brewhouse machine into fermentors.

Plate heat exchangers

Plate heat exchangers for cooling of hot wort before start the beer fermentation process. We include these plate heat exchangers into our compact wort cooling systems and we offer them also separately.

Wort aeration candles

The saturation of cold wort with sterilized air or oxygen is usually carried out before or during the beer fermentation process. The aeration candle is equiment for aeration of wort in the pipes before pumping wort into fermenters.

Compact wort coolers and aerators

Compact systems for cooling and aeration of wort . The compact unit includes the plate heat exchanger for cooling of hot wort to the beer fermentation temperature. Wort is saturated too by pure air or oxygen to easy start of the yeast activity during the beer fermentation.
