Topic: OT: Food grade silicone plug for drip cones? (22 msgs / 491 lines)
1) From: Greg Hollrigel
I posted this on the Forum, but thought I should post here, especially for
those who don't venture to the forum, and since many of you seem a lot
handier than I am.
I'm trying to find something to plug up 2 of 3 holes in my Melitta drip
cone. I was thinking a food grade silicone plug would be a nice choice. Does
anyone know of something like this or have another idea for plugging up the
drip holes on the bottom of the filter cone? Any internet links?
And, just in case it comes up, I already have the CCD and Aeropress, so this
would be for a different project.
Thanks,
Greg

Try a google search for "high temperature food grade rtv"
There is stuff that conforms to NSF standard 51, but I don't have that  
standard, so I can't say exacly how it can b used. Some sources say  
"food contact" while others say "incidental food contact". Anyway, rtv  
is pretty decent stuff, but I'm not sure how it would do in that  
situation. Anyway, just a thought to get you started.

I'd start with round wooden toothpicks because they'll answer the 
question if you really want to do it essentially for free. Then I'd 
tap it and use stainless screws or see if it's plexi or polycarb and 
use the proper glue to glue in a small piece of the same plastic.  If 
you need something silicon take it to a cooking store and see if one 
of those silicon brushes has strands of the correct diameter.

You could probably use some aluminum foil.  Make a tube of it.  Stick
it through the hole.  Mash the protruding ends down.    It's simpler
than trying to track down some kind of silicone.

Over the past few decades there has been some research indicating a link
between aluminum and Alzheimer's disease. Purists have tossed their aluminum
cookware & antiperspirants, but the research has been inconclusive: several
studies confirming and several studies denying any link.

I would think that the silicon caulk that is used to construct fish 
tanks would be safe. Fish seem to be very sensitive to chemical 
toxins in the water...

FWIW, I recorded brew times on all my pourover cones using the same grind and bean mass and found that it didn't change  based on the amount or size of the holes in the device. I think the Melitta has one hole, the beehouse has two and the Hario has one huge ~1/2" hole. YMMV, but I think the grind will give you more of a brew-time difference than playing with the holes. Nothing wrong with testing it out though and doing some experiments...that's half the fun!

I scored a ceramic cone at a thrift store with one hole.  I experimented
with a removable aluminum foil plug to control the contact time.  Worked ok
at home when I first tried it, but when I was making coffee for a tasting at
work, it made a mess.  I don't really recommend this very highly.
I ordered a second Clever Coffee Dripper when Tom got them back in stock,
and I ran them both this morning to make coffee for four instead of using
the vac pot like I have been doing since Thursday.  I had a conference call
to be on and needed a less user-intensive method.  Worked great and I just
grab the filters and put them in my grounds tray for later transport to the
garden.
I was also able to score Abid's Miraculous Tea Maker (under another label)
at a thrift store that stays in regular use by my tea loving daughter.

A number of people in the homebrewing world have worried over the years
about aluminum boiling pots.  Studies have been done showing that the amount
of aluminum leached into boiling water over hour long boils of beer is
miniscule, unless you scour the pot just before you boil (and even then it's
still pretty low).  Aluminum very quickly forms a layer of oxide that is
rather inert and forms a protective barrier on the surface.  You get
somewhere around 20 mg of Aluminum a day from your food (It's one of the
most abundant elements on the planet), so a few extra micrograms from your
cookware or your coffee gear is a non-issue.
The link between Alzheimers hasn't been proven either, but it's debated
rather heavily.

Thanks everyone.  Ben and Chris, your comments are noted.  My Melitta has 3
holes, so I wanted to plug up 2 of the 3 to see if I can increase the
extraction time.  I will see if my results mirror either of your two.

Have you considered altering the grind, or using different filter paper?

15) From: Greg Hollrigel
Interestingly enough, my cone has 4 holes and when I plugged 3 of the 4,
there was only a slight increase in brew time (less than 10% increase),
which surprised me.  So I guess my original idea is wrong.  I will play with
grind fineness as others have suggested, or just stick with the CCD or
Aeropress.
Can you engineering types explain why the flow time did not change that much
when you block 75% of the holes and all other parameters are relatively the
same, as much as I can control?
Thanks for the insights/suggestions.

Because the holes aren't the main restriction.

17) From: Sam49
If there is only a 10% increase in time using only one hole, it means 
that one hole can handle approximately 91% of the flow that the filter 
and the grind fineness created by your current setting allow.

Pressure equals force over area. If the area is reduced pressure will
increase. There will be a point where the increased pressure will not
compensate for the decreased area. Apparently, this has not occurred yet.

If changing the holes don't affect it, think. What other variables  
contribute to extraction speed upstream of the hole?

Yes, that is my next set experiments.  After my experiments this morning, I
was a bit on caffeine overload.  Grind fineness is next.

leads me to wonder why then there's a flow restrictor thingie on Technivorm
drippers if it's not going to reduce the flow all that much, or increase it
that much.  i haven't done the experiment there though!

My guess is they designed it that way. They want the basket to almost 
fill up but not overfill during the brew cycle so the coffee gets the 
most contact with the water.  I'd guess if you look closely that they 
have restrictors at both ends, water coming in and coffee going out 
and their choices for those has something to do with why they brew 
such good coffee.
