New Agitator!

edited February 2016 in Accessories

Needed to replace the weak and ineffectual agitator on the mash tun - we wanted to reuse the bulk tank paddle and mounting.

The old man worked this up in CAD, had a few parts fabricated at the machine shop, and we had the neighbor weld it up.

3/4 hp - 3ph run off a frequency drive. The gear reduction is 25:1. Everything is wash down.

  • Pretty good for some surplus deals and called favors.

  • The name of the game .... favours.

    Need a photo of the shaft coupling. They lathed it out of heavy rod stock and milled in the key ways. Needed to go from 7/8ths out of the reducer to 3/4 on the shaft. It'll get welded to the shaft once we get the length worked out.

    Can't believe the work those guys do, everything they mill looks like it should be on a rocket.

    Favors are awesome until you to hold someone accountable.

    Looks good. Work good?

    Always thought the amount of favors required in return was directly related to the quality of the favor provided.

    Will know how well it works the next mash. The old motor was only 1/20th HP and geared down to 30rpm - this is 3/4 HP geared down to 70rpm. I would have liked to go a bit larger, but the stainless washdown motor turned up at a price too good to pass up, and a local surplus guy just so happened to have the washdown reducer that was in the ballpark.

    Not to mention the poor milk tank agitator was nearly dead from trying to use it to mix a thick corn mash. We all thought it was crazy that it worked at all. Last week though, it was routinely stalling and overheating at the start of mashing, when the corn was settling at the bottom. Probably doesn't help that we were beating the poor thing to hell trying to get it to do something it wasn't designed for. Hopefully the higher speed can keep a bit more in suspension.

  • Lesson of the day - a thousandth of an inch might as well be a mile.

    After we sorted that out - it works great.

    Lesson two - if you can't fix it with a hammer...

  • Nah, another trip back to the machine shop where they reamed it out.

  • just heat up the outside... it is called an 'interference fit'... of course, getting it off is a different story...
