The Impact Of Continuous Agitation During Fermentation

To evaluate the differences between two batches of the same recipe where was fermented under continuous agitation while the other was fermented with no agitation. METHODS Feeling a tinge of sadness due to not having an Amber Ale on tap, I selected this as the style for the current xBmt and based the recipe off of a NHC winning beer.

Powerhead for surface agitation? General Discussion

Oct 19, 2016I was wondering if there was a powerhead that is easy to aim up for max surface agitation. I have a wavemaker but that was not cutting it, the surface was still messy. And the power of it was keeping my clownfish on the other side of the tank

The Effect of Bath Temperature and Agitation Rate on the

The second parameter of interest is the agitation level. In general, agitation increases the rate of heat transfer throughout the quenching process regardless of the bath temperature. Agitation will breakdown the vapor blanket much earlier in the quench and force the transition to nucleate boiling [2]. As a result, a stage of slow cooling is cut
