Gear reduction unit or a VFD is another way. I am not in favor of the pulley system. 20:1 or 15:1 reduction ratio would work. I am working on one myself.
You can find a decent price gear reduction unit at surpluscenter.com.
Good lucks
Do you happen to have the size of the shaft for the roller? Is it 5/8" or 3/4"? I am planning to build a motorized grain mill. I just want to be able to couple it with the same size gear reduction shaft.
Thanks,
As others had posted previously, 55 gallons kettle needs a dual 5500W heater elements. I have 25 gallons pot with a single heater element, it would take close to an hour to bring the cold tap water up to 160F for mashing. Dual 5500W elements would require at least 50 or 60 AMP circuit from the...
I am curious about the price of the control box at time you put the system together. I am looking at options to build a second box to support a 25 gallons boil kettle.
Hotel room in Augusta, GA is really expensive during the master week. I would recommend staying the next town closer to it, traffic is really bad too.
The River walk is very interesting area, take your time to explore the area during your visit.
Have a safe trip to the South.
