Way Of Wort Aerate In Craft Brewery Equipment

In complete craft beer brewery equipment, wort aeration device is a necessary part.
Wort aeration is simply adding oxygen to wort prior to fermentation tank. This is an important practice for several reasons:

Adequate oxygen levels in the wort ensure that the yeast grow and reproduce during fermentation
Inadequate oxygen levels can cause poor attenuation (how much sugar the yeast eats)
Adding oxygen to your wort will improve the quality of your beer
In a nutshell, yeast and oxygen need each other. Oxygen promotes healthy, active yeast. Oxygen is essential for the yeast to produce the sterols and fatty acids needed for cell growth. The challenge is to maintain adequate oxygen levels in the wort delivered to the fermentation vessel. Not having proper oxygen levels in the wort that the yeast is feeding on can cause a lag time before fermentation starts, incomplete or stuck fermentation, or excessive ester flavors.

How do you add oxygen?
Inject the oxygen into the wort in the transfer line after the plate chiller using an oxygen stone. Sterile air can also be injected. Ideally, a range of 8 to 10 parts per million (ppm) dissolved oxygen is achieved. The injection rate of air or oxygen must be monitored to avoid too little oxygen or too much oxygen.

When should you add oxygen into the wort?
Temperature and specific gravity affect how oxygen dissolves into wort, colder and less concentrated wort absorbs more oxygen. Since wort loses its oxygen during the boiling process in brewhouse equipment, it must be replenished before fermentation vessel. Oxygen should be put into the wort after it is cooled and before the yeast is pitched.
