Anyone have an interest in rotary mixers?

I sure do, but not for liquids. In regards to fluid dynamics, I can't for the life of me see how this would accomplish much with liquids.

Not my line of work, but that looks more like it's intended to give just enough mixing to keep solids in suspension. With liquids of different densities like PG and VG, I don't see how this would do anything at all.

Here's my rotary mixer before the sides and hinged lid were put on. It handles 2 5qt barrels are a time.

perhaps if the insides had holey baffles? still I think if I had a chunk to plunk I'd go magnetic stirplate.

For liquids, stir plates are far superior.

Can you make one lightly heated? Like those hot dog things at 7-11?

Only for hot dog flavorings.

There goes my bacon pizza juice.

it's ok if you do a bacon pizza rolled up tortilla thingy they got on those heated rotary's (what the f are those called again?)

Wouldn't this separate the flavors?

IIRC this should mix them by agitating them. If they were mounted to something by one fix point on the bottle and spun fast enough, that would separate them.

Right, the effectiveness is getting the correct RPM so the air bubble pushes the liquid around itself. So the air bubble is always "chasing" to the top. I think 0-30 RPM should cover anything from a 15ml to 1 gallon.

It will be faster to mix by hand. Btw, magnetic stirrers are dirt cheap and they work.

No. This is a common method for mixing in several industries.

Off topic but, could I duck tape a 30ML flavor I REALLY want to try to my tire and go out for a 20 min night cruise?

Wrap a towel over them and put them in the dryer for like 5 minutes

if you attach it well to the rim then it may work. This assumes that you neither throw the bottle or smash it.

I've been ~~thinking~~ dreaming about when I get really big on production, mixing batches in 55 gallon drums and not mixing them but slowly rotating them like this for 3 months. than releasing.

just make 5 gallons and run down to home depot....I should do this just because it is possible.

I used a similar setup at a previous job to process soil samples. We put titanium rods of different sizes inside the containers and rotated them for several days. It doesn't seem like that would be an ideal method for liquids though. It works great on hard to grind solids because they get trapped between the rods where they overlap and are broken down, you wouldn't get the same effect in a liquid medium.

We use ar-12 thumblers rock tumblers for 1l and 1gal aliquots to accomplish the same task :) ~150-200 for a new unit

We did something similar with potting polyurethanes. If you want to go hardcore - http://www.globalindustrial.com/g/material-handling/drum-barrel/drum-mixers/portable-drum-rollers-99690

Off topic, but I use this for mixing mine, and it does an awesome job.

oooh, this shows promise, considering I could make one of these very easily with technic legos.

hah! yes, but rotary mixers are seriously fucking weird as hell to mix on. was forced to DJ on a UREI one time and felt like I was buttoning my shirt with one hand.
