Topic: coffee cooler (was Tamale Steamer) (14 msgs / 317 lines)
1) From: kevin creason
No... the conversation wasn't "Tamale Steamer", the coffee cooler used to be
a tamale steamer but the company was just too short-sighted to see my needs.http://picasaweb.google.com/ckevinj/CoffeeBeanCooler/photo#5220237944482943410I still have work to do on it, i hesitated posting it yet, but I do need a
little insight. I was really wanting to go all-stainless but gave up and got
this giant aluminum tamale steamer because it is just nearly perfect.
Nearly. The grate at the bottom has holes just too large and I would lose
nearly all my coffee beans to the heat sucking apparatus (was shop vac). So
I bought a 3-pack of grease splatter screens and bent the handle of the
large one perpendicular, and it fits perfect in the tamale steamer. But the
screen is too fine, the chaff collects at the bottom (underneath the coffee,
mostly) and eventually gets back into the coffee as I try to get the coffee
out.
So.... where can I find some aluminum or stainless steel hardware cloth of
the screen size I want for my cooler's tray? The big box home improvement
stores have bare or galvanized steel and that doesn't seem food safe. I
thought about stopping by the boat shops that repair aluminum boats-- do you
think they have what I need or could just weld wires across the openings?
The way my device works is very simple, and based on the ideas of people on
this list who have gone before me down this path:
drill hole in bottom of bucket and suck air through the beans to cool them
down. My heat sucker apparatus is a 5 HP shop vac, the bucket is an aluminum
32qt Tamale steamer, and the screen is a large grease screen. I cut a hole
for the shop vac tube to go in the bottom under the steamer's grate, I put
an ice pack inside the hole to cool the air entering my heat sucker
apparatus so it doesn't melt (I hope), put the steamer grate in, and the
grease screen on top.
I dropped in 3# of beans snapping into second and the IR thermometer showed
me 100 degrees (almost ambient) in just over one minute. Not bad!!!!!
I'll be very very very happy when I have a screen that allows the chaff to
leave the premises too.

Hi Kevin, Today I paid my first visit to our new super walmart. In the 
kitchen section is a package of pizza pans called pizza crisper. One is 
about 14 " in dia with lots of holes. Sorry, I did not notice the price..
Could be what you are seeking.
If I already did not have a SS Japanese soil sieve I'd a been all over it!
Good luck with your quest.

Hi Kevin;
Did you get the file I e-mailed to you that showed my cooling setup?
(others that want to see the file, let me know I am happy to send it).
Just wanted to check because sometimes the spam filters nab messages I
send directly.

Yup! Thanks- I will have to watch that nozzle and make sure it doesn't melt on me.
I went looking at perforated pizza pans but didn't find the right one yet... Need to take some measurements and go back/ try another store.

"My heat sucker apparatus is a 5 HP shop vac"
First, Is it a fact that you actually have a 5 HP shop vac? 1 HP = 746
watts, by definition.   746 X 5 = 3,730 of James Watt's personal units.
3730 watts / 120 v = 31 amperes, or 15.5a @ 240v.
A 120v 30a circuit would be overloaded, and a 10/3 SO or SOW copper wire
pigtail would be over for an insulated wire cable. I doubt if you have a
spare 240 volt circuit, that most home espresso baristas don't seem to have.
Cheers, Mabuhay -RayO, aka Opa!

It probably just sounds like it has five HP. No telling what might be
written on it. I think mine says, "quiet". Ha!

Good point, so how do they manage to put a label on my Ridgid shopvac
that says 5.0 peak horse power?  It only has a 14 gage cord, and I
know it does not pull much over 10 amps, or 1,100 - 1,200 watts.
(10amps X line voltage)

Most Likely with a silk screening machine.
Da Dum Chi!
Sorry.  Couldn't resist.
 It's early, and I have had no coffee...

I think you posted to the wrong list, Rayo.
You probably should over to alt.bash.siriuscybernetics or something to
complain about the marketing practices of companies such as Ridgid, and
Sirius Cybernetics Corporation.
I'm just telling you what big freaking heat sucker says on the label.
If it's that big of a deal fly down and measure it while I cool a roast and
take it up with the Man.

10) From: Rich
Peak surge current(RMS), not the developed HP of the motor.  Just like 
they manage to seriously over rate audio equipment power.
That would be the maximum peak surge current(RMS) multiplied by the RMS 
value of the rated applied voltage.  You will find that the starting 
load of a motor that is powering a centrifugal device is 3 to 5 times 
full load running load.

Ray,
While your figures are correct, they are based on the erroneous assumption 
that one mechanical HP is equal to one vacuum HP.  The HP rating of a vacuum 
is only vaguely related to the mechanical input.
First, a quick history lesson:  When James Watt first invented the steam 
engine, its first use was to pump water out of coal mines. This was 
previously done by horses pulling containers out of the mines.  Each horse 
had a quota of water it could haul in a day and for each horse replaced by 
the steam  pump, the pump was said to have one horsepower.  Much later this 
was standardized into a mechanical standard measurement.  For some unknown 
reason, vacuum devices adopted a different definition of a HP.  I don't know 
the standard, but I believe that it goes back to the original in that it 
relates to the amount moved in a specific time.  As a result of the two 
different definitions of HP, you have a situation where a 1/4 HP electric 
motor can power a 2 HP vacuum.  This sounds like it breaks the laws of 
physics, but it is more of a breaking of the rules of language.
As a result of this dichotomy, the OP may well have a vacuum rated at 5 
vacuum HP that will easily run on a 110 volt circuit.

"...you posted to the wrong list, Rayo."
 Au contraire- I was responding to the cited text. I understand the
arguments, but I have never been able to understand the success of Madison
Avenue in twisting physical descriptions to yield $ales increase.
I thought it was interesting that the biggest Heathkit amplifier I had built
in the early 60's was rated at 70 watts. Playing "Bach on the Biggest," a
Mercury LP of the Atlantic City Convention Hall organ would cause the
masonry living room floor to shake at '315' in Peoria.
RMS power vs "Music power" -ro
Engineering disasters- assume nothing.
