Just a quick good morning to my homeroasting friends & family from Kona. We got in late last night,
stopped at the KTA Market at 5 to 10pm, they closed at 10! Needed a few essentials for the morning
like good water! Started the morning with a Zass Turkish mill ground French Press of Wood's Captain
Cook Estate 02 Kona, last years cupping competition winner, seemed appropriate! Followed by a pot of
Sulawesi and now a final before we head out cup of Panama Maunier.
FYI I roasted 10 batches for the trip Friday. Vac sealed 32gr individual whole bean pouches direct
from cooling then to the freezer. Of course, out of the freezer for the trip, back in the freezer
now. Oh, 32gr because that's a full load with the Zass Turkish Mill. I make about a 24oz press pot
with it, our travel 32oz press 2/3 full. Our weeks coffee menu will include Wood's & Brocksengate
Kona, ISH (two batches, 8 vac packs), Uganda Budadiri, Australian, JBM MB and I forget the rest and
am too lazy to look through the freezer to see what I missed! I do like variety in my coffee:-)

It's no longer cold! Currently at the Honolulu airport waiting for our
connecting flight to Hilo in a couple hours. Playing with a new *toy*, WWAN.

Yes, Frankie is languishing at home. No biggy. Didn't want to risk being
held up and missing our flight explaining and demonstrating so some other
time... Roasted 1/2# batches of Guatemalan Filedelfia, Kenya Mika, Sumatra
4365, Australian Skybury and Wood's Kona to *tie us over* 'till we pop over
and roast some Kona with Gus (Pele Plantations) and David (Kona Premium
Coffee). That's what I'll call having fun on vacation! Plan on taking and
posting some picks of their operations this time.
Bill if you see this I'll give you a call later this evening or tomorrow.

OK, Mike....
I was about to call the hotel, to see if you had gotten in yet.

Why don't you pick up another roaster to bring home
with all the coffee. http://www.coffeetimes.com/coffee-roaster.htmMike Walls

If someone here built that, I would be rather impressed.  For a $3000 4lb 
roaster with a 30 day lead time, I am less so.

Most of that lead time might be waiting for that Dayton blower to arrive.
Interestingly, that's the same blower I recommended to someone for a hot air
roaster. Notice that there is not recyclling of heat.

Is it possible to recycle heat with the blower itself, i.e. a portion of 
heated exit air fed to the supply side?  An acquaintance familiar with 
blowers said just the heat conduction via the fins and rotor would damage 
the motor.

Yes, it is not only possible, but is done. Heat conducted to the motor bearings
is a problem. The cure is to add a heat slinger. This is an aluminum disc
slipped over the shaft between the motor and blower casing. Heat coming through
the shaft enters the slinger and is dissapated to the atomosphere. The spinning
of the slinger helps in this regard. The mfgr. says the blower can operate at
450F if a heat slinger is added (if memory serves). I'd say that a good portion
of the air could be returned to that blower. Dan

The small Sivetz I believe, though may be mistaken. Though not seriously in
the market I'm going to give them a call to find out who they are! Shipping
would be horendous and if I was looking at a Sivetz I only live a couple or
3hrs away drive...

So yesterday I tried again to lift a pound bean mass with my popper. 
Merely attached the inlet of the Stinger to the top of the lamp chimney. 
When I turned it on, wow, the beans were dancing in that chimney, lots 
of air was blowing through. Then I realized that I really needed a 
screen over the top of the chimney ( to keep those lively little beans 
from getting too involved with the vacuum), and of course I could blow 
the exhaust form the Stinger into the base of the popper,.. and then, 
and then.. if I turned on the heat... the whole vacuum would just melt!
Oh well,

I've seen diagrams of how people in the 1800's created compressed air by 
using water dropping through pipes which had holes in their sides which 
would cause air to be sucked in, which would  then be compressed by the 
weight of the water into an underground container/cave...Darned if I 
remember what they were called...some kinda flue..

Hi Dan,
Please tell me what blower you are referring to, where do I look at one 
or order one?
I for one like the idea of recirculating the hot air for an air popper, 
and would like to try it.
Thanks for mentioning this again.

Hey Mike seems a bit high don't you think?
$2700 for a 4 lb roaster.
But hey, you are there, that would save on shipping:O)

20) From: Ed Needham
The blowers I've seen that can take the heat have the motors isolated from
the body of the blower via a belt drive or a coupling.  I'd assume the fins
and bearings would be designed for high heat.

Peter and Ed,  Here it is, the smallest Dayton blower you can get from =
Graingers. It comes packaged with a sleeved bearing motor which will =
last a long time doing roasting. I can tell you it lasts 3 years running =
10 hours a day, I just changed it out for a ball bearing version last =
The nice thing about this unit is that the exhaust outlet can be rotated =
to any angle and even reversed if you also reverse the motor direction. =
This makes for a easy installation. 
The one I have is the 2C940, 3450 rpm, 1.3Hp, delivers 216cfm at 2"SP.  =
They also have 1725rpm models from 1/6Hp (7C552) to 1/2Hp (7C554), =
delivering less static pressure. The heat slingers I spoke about aren't =
available in 1/2" shaft sizes, but you should be able to make one =
yourself using a 1/4" aluminum disc bored and tapped for a set screw.  =

23) From: AlChemist John
Dan, are you using this for a roaster or some other application?  What 
temperature air were you blowing?
