Blowouts happen if the fermentation creates too much foam (krausen) that pushes through the airlock, perhaps causing a large number or contaminating the beer.
Suppose we want to prevent cross-contamination by Bubble airlock for granulation spot, We're going to Develop an airlock place in between granulation spot and corridor and develop favourable in airlock force by providing much more air by way of HVAC say it can be 20 Pa.
This process successfully retains ambient air out of your fermenter whilst also providing a good amount of duration of tube for the foam to bubble up.
If your DP from the airlock is reduce compared to 1 within website the adjoining rooms a “sink impact or downturn” is made, as you will discover airflows to the airlock.
