As an aside, our whole plant is state of the art and is designed to be as energy efficient as possible, recovering heat from one part of the process to the next. We produce steam via a pressurized steam boiler which is gas fired. This is used as our heat source throughout the process. Steam is carried around the plant in the two largest pipes on the pipe rack. They become so hot that the pipes expand in length and must have 6 large u-bends along their length simply to absorb the movement. In terms of heat recovery, when wort is extracted from the lauter tun, our heat recovery system reduces the temperature to 20°C for fermentation using heat exchangers, with the extracted heat being used to heat the water for the next pass through the lauter tun. Similarly, hot water in various parts of the process is stored in insulated vessels for the next day’s production.
