Agitator speeds

[Palmetto Coast]

What speeds are you looking at as optimal for your mash agitator? We received agitators that only spun at 40rpm (WAY too slow). We are looking to purchase one or two new motors now. We are using a 600g mash tun.

Thanks,

Todd

Depends on your mash viscosity, mash density, geometry and size of tun, and the geometry of your mixing impeller. Under the right conditions, 40 rpm could actually be correct, on other conditions, 1000 rpm might be. Although most likely you will be somewhere between.

Todd, might need to change just the gearbox, or invest in a variable speed drive.

Thanks for your help. We are looking at switching the gearbox or having the coil redone. A VFD would have allowed us to slow it down. It was geared crappy to begin with.
