Most people probably know that the oxygen could easily cause wort aeration during brewing with your brewery equipment, that would make the wort with darker color, worse mouth feel and not good for the beer stability. But how to avoid it when brewing with your beer brewery equipment? You need to know firstly how did this happen.
So what would cause the wort aeration?
There are generally three main reasons as below:
(1) . The mash flowing into the vessel on top of the tank
(2) . Much faster stirring speed
(3) . Transporting the mash via pump
And what should we do to avoid it when brewing with your brewery equipment?
Please following the methods as below:
(1) . Installing the malt hydrator
(2) . Making the mash goes into vessel from bottom of the tank
(3) . Better avoiding cavitation when transporting mash
(4) . Making the grain rake or agitator with VFD
The current brewery equipment or brewhouse working generally do not use strong or powerful agitator any more, instead with the one could be modulating rotating speed via VFD according to the capacity of mash tun or cereal cooker. Besides, when separating the mash under decoction mashing, the agitator should be stopped for about 5~10 min, that would make the undissolved malt settle down to the tank bottom, and stirring the mash for 3 min after combined mash
(5) . Using inert gas like N2 etc during mashing
