Anyone experience a "worn" bowl for a Hobart 60qt?
« on: July 24, 2022, 01:36:15 AM »
Hello,
I am experiencing an odd problem when mixing dough in my current Hobart 60qt mixer.
Based on my 20+ years of experience making dough using several other similar Hobart 60qt mixers, I find that when using my current mixer, once the "ball" of dough roughly takes shape, and then throughout the rest of the mixing process, it does not move around the bowl as it has done with all the previous units I have worked with. The dough hook seems to primarily be mixing the center of the dough mass, and the outer part of the dough mass rotates very slowly like it is experiencing some type of "drag" from the inner surface of the bowl.
With every other unit I have used, once the ball had initially balled up (-oil), and again after re-balling after oil added, the entire dough mass would freely follow closely behind the hook in its entirety, familiarly “slapping” freely around the inside of the bowl as one complete mass.
Even in the later minutes of mixing, I can see that the lower part of the dough mass moves around the bowl very slowly relative to the upper dough mass closer to the hook.
My dough recipe is solid and time tested, and has never been an issue before.
My prime suspect at the moment is the bowl when considering it’s age and condition.
The bowl is likely easily 40+ years at the least.
Besides it’s many dings and dents, the inner surface is 85% shiny on the upper part, but the closer to the bottom there are many grey non-shiny areas, as well as the bottom center having a very slight yellowish-orange tone to it, as if possibly being some type of rust or corrosion.
I am hoping to find someone who may have had a similar experience to give me some insight as to whether I am on the right track or not regarding my suspicion that my problem is likely due to the age and poor condition of the bowl.

Thanks

not sure your model but you should be able to adjust the agitator clearance. page 16 and 17 of the attached manual. https://www.hobart.com.mx/pdf/ManualOper/F37287.pdf

Interesting to know about models having an agitator clearance adjustment.
Thanks
Not sure older P660 have such a feature.
I will look into it...
Appreciate it..

That bowel is SHOT!  Get rid of that and should have a long time ago, surprised this did not happen a long time ago.  Bowels do wear and it does take years.  What you first find is the surface inside is no longer polished and moving your hand over the inside you feel resistance. Over time the surface wears and become more resistant.  Some bowels are layered alloys with a harder polished surface coating that eventually wears.  Time for that bowel to go…
