I Wonder If This Would Work For A Presto Stirrer

Recommended Posts

That is awesome. I think the only factor would be the thickness of the plastic and if the stirrer has enough power to mix it up. It is definitely worth a try.

@Ghost: Let us know if it works out.

I'm thinking you could heat the plastic stirring with a spoon or spatula and only add the robostir once it's gotten to pouring consistency.

Here is a link. This company sells pots for commercial operations from lures to food services. There is a viscosity chart on the near the bottom that someone smarter than me could use to help find a good motor that's small enough to fit a presto, but strong enough for plastisol.

Here is another for some plastisol, It even has a viscosity chart at the bottom, anyone use this stuff?

Thanks,

George

Not to drag up an old thread, but mine arrived this morning. I tried it out in a pot of water and it works as advertised. If I get a chance, I'll try it in the presto with plastic later. I can see I'll probably have to hand stir the plastic until it passes the gel stage, but after that this thing should work fine.

Well... let me put this one to bed. Evidently, 325 degrees Fahrenheit in the U.S. is hotter than 570 degrees Fahrenheit in China . Within 20 seconds of hitting my 325 degree plastisol, the stirrer paddle melted off. On the bright side, they are going to refund the purchase price and shipping and handling.

Oh well.. Somebody had to be the guinea pig.

Thanks for the report bryanmc, I'm sure this will help others in the future.

Pity it didn't work out. It is very good that they are refunding your money, considering what you used it for, LOL. You will have the guys in R+D scratching their heads for months, trying to figure out how Momma's soup did this to the plastic stirer. My ex wifes cooking would twist a stainless steel stirer.

Thanks for reporting back.

Actually Dave, I told them on the phone exactly what I used it for. The customer service guy agreed that it shouldn't have done that at only 325.

Well that is honest and the company seems good to deal with. Just a pity it didn't work out. It is always nice to deal with companies that have a code of ethics.

I have just been doing some research on wiper motors, for another project. These commonly available motors are more than capable of dealing with the loads involved with stirring plastic and they are already geared down to suitable ratios. A bit tedious to power, but a cheap car battery charger is well capable of delivering enough power. The motors are readily available from scrap yards, second hand parts or reconditioned, at reasonable prices. If I was to build a stirrer, this would be my route.

Thanks for taking one for the team.

I'm disappointed. It seemed like a really neat idea. :(

Wonder if you could have adapted a metal blade to replace the plastic one. Looks like the three glides were also made of plastic.

I think it was a bit of hype suggesting the 700 degree tolerance and they never expected to be called on it by cooks who only use it for sauce and soup. Still, something my wife might like for the price.

Too bad they didn't include shipping both ways in your refund.

Well.. I'm only out $4 to ship it back. As far as the blades, my thought would have been to maybe try a cut piece of a high temp silicone spatula. The other issue that I didn't address was that because of the 1/2" forward lean my pot has, it didn't want to turn, it stuck at the low side. I'm sure with a level pot it would have rotated fine.
