I bought the grandaddy of all whirling blade grinders
on eBay. It's 400W, and has hose barbs for attaching
coolant lines to both the grinding chamber and the
lid on the grinding chamber, which are both cast metal.
I think I paid $30, with shipping.Brand? And if you were the one bidding against me I'm going to smack
you silly! Just kidding 🙂 I hope you enjoy your new purchase.
It's a Chemical Rubber Company Micro-Mill. I would
guess the intended use was to grind mineral fillers
to be added to rubbers and plastics. Of course,
I'll clean it extremely well before trying to run
any food through it.
Only one person bid against me, with a max just
above the starting bid, so I sniped it from them
for something like fifty cents or a dollar above
the starting bid. It was like $10 for the machine
and $20 for shipping.
It has unusually nice styling for a piece of lab
equipment. It's got a jadite finish, like an old
Hamilton Beach malt mixer, and a nice squarish
truncated pyramidal body.
Another piece of lab equipment I've been thinking would be
interesting would be a microfluidizer from Microfluidics.
I've seen a couple on eBay, which went for very
reasonable prices, but in unknown functional condition.
The drawbacks are a) the countertop versions run off
of compressed air, not electricity, b) replacement
parts are out-of-sight expensive, and c) they cannot
be cleaned, except by passing cleaning fluids through
it. If you don't know what the previous owner used
it for, you really can't use it for food.
What would be cool is that the microfluidizer is the
best machine I've ever seen for producing an emulsified,
smooth product. One of their major uses is in the
production of high-priced cosmetics -- this machine is
one of the highly guarded secrets in that industry.
I'm very curious what it would do to chocolate.
I think it could achieve a texture that might be
beyond anything any other technology has yet achieved.
