Regarding steam condensers for brewing kettles, we have two types to choose from.
Our standard configuration is designed with the steam piping inside the chamber. The steam piping is fitted with a nozzle that is directly connected to the tap water, so the nozzle can spray water to condense the steam. However, steam can also come in contact with the piping surface and at lower temperatures, the steam may liquefy and flow back into the kettle tank, which will affect the wort. To prevent backflow, a recess is welded inside the pipe and additional small tubes are installed through the kettle tank, and then the condensate drains out through the small tubes.
Considering that not much steam will be generated, we think this is fine for a small capacity brewery.
In addition, the condensate can be used for tank cleaning, but not for brewing due to the low level of sanitation.
However, for high-capacity breweries where there are no local government regulations on steam and the steam does not affect neighbors, we believe it is best to consider venting the steam directly, which can result in significant savings in municipal water consumption. Depending on the configuration, the steam piping is connected directly to the roof with a chimney, and additional T-pipes are added to prevent backflow.
