Industrial mixer for small scale manufacturer- emulsions

@johnsutw, you should see if they’ll make a blade that will fit one of the dremel shafts, but let us know about the high-torque, high-speed drill.
-
At some point, it just becomes more cost-effective to buy one of these:

>Will now look for a high torgue and high speed electric drill, and use tonyh’s
>idea of using the “Speed Controller, Variable AC Motor Rheostat” (from his post above)@johnsutw: The plan I gave above is just a surface (not too involved) plan. In this plan the “Speed Controller” does not range from 0 - 15,000 rpm (etc). To have 100% rpm Rheostat control, the 2-speed switch in the stick blender has to be disabled internally. (Many squirm at this dirty work). Doing this will give the Rheostat 100% speed control from 0 to 15,000 rpm (for example). You will be able to mix gels, shampoos, etc.
If you are going to mount the drill to a lab stand, and to have 100% speed control, you are going to have to disable the power switch and connect the wires from motor to internal power cable of drill. As is, the drill switch is between the motor and power cable. If you can do that, then connect the Rheostat always, and buy shafts and blades/impellers.

Something I considered at some point was to use a woodworking router to power a saw tooth dispersing blade. Then I got a homogenizer and forgot about it. Routers come in different powers (up to 2.5 HP), with variable speed controls up to 30,000 rpm, and have collets (basically a fix diameter chuck) of 1/4 ,3/8, or 1/2 inch.
Routers can be expensive; but there are some cheap ones that could serve to prove the concept. I wouldn’t use a long shaft to mount the dispersing blade, though. A collet is designed to hold short bits and I don’t know how it would behave with a long rod. I am afraid that if it is too long it could start vibrating and break the collet.Like with any other equipment, a router would need some type of stand or support to hold it in place.This is just an idea I wanted to share. -
I have bought an 18 volt battery powered hand drill and 2 varieties of paint stirrers for mixing my lotions. I would appreciate any advice or suggestions regarding use. I have cetearyl alcohol & ceteareth 20 e-wax.

This is the one for cool down phase

How do I post a picture?

I have started a new discussion, but I can’t work out how to post the pictures

@Perry?

@ botanicalsecrets
Did you try to copy and paste your pictures? I just tried and worked. -
To post pictures…
In the icon bar above where you type in your comment you’ll see a bunch of different icons. ‘B I abc, etc.The 6th icon from the right is a box with a green screen on it. Click on that and put the web address of the picture that you want to upload.Of course just pasting the picture into the comment box might work too. -
@ Ruben while this is a novel idea. I would recommend to anyone. Do not try to use a shaft impeller on a router motor. At 30,000 rpm’s it will fold up like a pretzel. The low speed of a drill motor is ok for slow speed mixing.

Found a decent deal on Amazon: Generic Chinese brand 100 - 2500 rpm 60W mixer with digital readout, 110 - 230V, 2 yr warranty for $440 including shipping, impeller and stand.
https://www.amazon.com/gp/product/B00CF3J07E/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1And a 8 mm shaft 55mm sawtooth disperser for $64 (I bought the last one)
https://www.amazon.com/gp/product/B00CF3J07E/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1Seems like a good deal for the home gamer / semi-professional who only use the tool on occasion. One concern, is there any need for higher RPMs?
-
You can buy a Chinese emulsifier for not much more.
-
Not a good option for small scale sample making which Is what I’d use it for:
Rotor/Stator won’t fit into small vessels.
Higher minimum speed.
Slow China shipping, and imagine warranty returns, lol.Other emulsifier/homogenizer options are typically repackaged dremels with 5000 rpm minimum speed or used giants which require $500 rotors to work. At that point you might as well use an industrial immersion blender instead.
You could get a 40 - 6000 RPM overhead mixer used for $500 on ebay though: http://www.ebay.com/itm/Caframo-Ultra-Speed-Digital-Stirrer-BDC6015-40-6000-rpm-/232010563536?hash=item3604e83fd0:g:0SMAAOSwyKxXhQm-
New $1500.
-
Actually found a $600 homogenizer that goes from 300 - 23000 rpm http://www.ebay.com/itm/2016-New-Lab-Homogenizer-Disperser-Mixer-AD200L-PN-300-23000rpm-12-18G-220V-A-/282052997980

Catering machinery suppliers may come up with the goods.
Good thing there is that they will/should be able to supply sizes from domestic kitchen/small restaurant to large scale industrial production. -
Restaurant supply stores can frequently be a source of instant gratification for buying lab supplies.

$160 including shipping, variable speed from 530-3100 RPM with LED readout. I mean what more could you ask for - changing beakers has never been easier
No lotion too thick lol.I tested the Generic Chinese unit described above, comes with an external 110 - 220V PSU outputting 24V DC, 72W. Can be overclocked to run at 2750 RPM through the menu. Silent brushless DC motor and nice timer feature, but too much run-out (spindle wobble) for my liking causing vibrations at certain RPMs. If not for that it would have been 5/5.
Tip speed with 55 mm sawtooth disk:
Circumference = 3.14 * 0.055m = 0.173m
Speed = 0.173m * 2750 rpm = 475 m/min or 8 m/s -
That would be perfect for my basement - a creams/lotions mixer and a woodworking drill press, all in one package. What more could you ask for?
Seriously, it’s stuff like this that gets me so annoyed at the lab mixer companies. Something just like this on a lab stand and in different colors would run about $2,000 - $3,000.

A problem I’ve found using an engineering drill press press as a mixer is that there can sometimes be an oil leakage from the gearbox. This wouldn’t matter using the drill for its intended purpose but it could spell ruin for your delicate emulsion.
I’ve experienced this twice when the mixer/drill was working very hard for a long period and over a heater but, for normal uses and as long as an eye is kept on proceedings, these drills are excellent for the purpose.
-
Fixed the Chinese unit, chuck wasn’t seated all the way up the spindle from the factory. Now runs totally true and quiet and it actually goes up to 3000 rpm. 4.5/5.

I make lipstick, lip glosses and body butter. Would any of the mixer listed in this thread work for these thick bases? Batch size would be 100 grams or more. I reached out to a company called Silverson to ask if they had anything for small batch formulators. Waiting to hear back from them.
