Craft beers is more and more popular in the world, so more and more microbreweries were established. To keep up with the competition, they are trying to make the operations to be as efficient as possible to make the cost lower . In beer brewing equipment, beer cooling is an important part for increasing efficiency. So heat exchanger is very important.
Benefits of heat exchangers during production
One of the biggest benefits a heat exchanger can provide is a decrease in energy usage and emissions, both of which benefit the brewing process and the environment. A quality heat exchange system also cuts down on the amount of water during the brewing and tank cleaning procedures.Once the liquid has been made into wort, it needs to be cooled down as fast as possible. Lowering the temperature of wort as quickly as possible is crucial in the brewing process, and the bigger an operation is, the more difficult this process becomes. This can be done in a number of ways, including adding ice to the kettle, putting the kettle in ice, and using either a wort chiller or heat exchanger.
The heat exchangers most often used in breweries are plate heat exchangers, which consist of a series of plates. As a hot liquid flows along one side of the plate, a cold liquid flows along the other side of the plate, producing a “heat exchange” across the plates.
In the brewhouse, hot wort is run through a heat exchanger and cooled by the water or refrigerant running along the reverse side of the plate in the opposite direction. A properly sized heat exchanger can get the right temperature in less than an hour. Once the wort cools sufficiently, it is ready for fermentation.
The cold water then gets heated and returned to a hot water tank to be used for the next brew or for some other purpose in the brewery. The heat used to bring the wort to a boil can be reused to heat cold water entering the building. If a plate heat exchanger uses refrigerants, it can also be used after fermentation to lower the beer’s temperature and allow the aging process to take place.
That’s how heat exchanger used in microbreweries. Within Tiantai beer brewing equipment, the heat exchanger efficiency is very high.
