sintered glass filters....or your best filtration systems

[Equality 7-2521]

hi all,

I was wondering if anyone had heard of sintered glass filters...or if anyone has come across a really good filtering process

Never heard of them. If you come up with an efficient filtration process for these extracts, most of us would be very interested. Currently I use unbleached coffee filters and lab filter papers.

how well does the lab filter papers work..do they leave a taste.

No taste I can detect. The ones I'm using are cellulose so they are essentially thicker coffee filters. They are bleached white though.

I can't get VG extracts to pass through any reasonable filter, even a coffee filter, without pressure. Even when hot. Although, maybe it's not hot enough?

Currently, after a quick strain, I'm filling the front-end of a needless syringe with organic cotton and filling it from the back with the extract (removing the plunger to do so). Takes a lot of pressure to get it to pass the cotton, but comes out pretty clean, not perfect though IMO.

Has anyone ever experimented with using a wine plate-filter?

Consumer grades looking something like this?

Perhaps if there were a smaller system out there. Capacity for 5 gallons in one go would be awesome, but totally excessive for most of us.

lol

that is the smaller system

As a brewer, I can tell you right off that a plate filter isn't going to work. It's tough enough pushing beer through one & they clog up very, very quickly, even with minute amounts of yeast and proteins in solution. Also they won't work with just gravity. They're designed to have beer pushed with CO2 in access of 5 PSI.

I use a jelly strainer, you can buy these bags anywhere they sell canning supplies. Their tight woven so no partials from your extraction will get thru but you can squeeze all the goodness out without having to wait for the slow drip of the coffee filters. Toss your scraps in the trash, wash the bag and reuse.

For our coffee maker we use one of the gold plated screen baskets. It's about time to replace the old one and I wonder if this would work for a first pass before the paper filters?

Paul, that strainer should work fine for removing the bulk tobacco. I use a cheap mesh strainer from Walmart.

Thanks. I'm frugal sometimes and lazy and would want to get the most liquid out without too much work.

 

[johni]

I hear ya. Pretty frugal myself and I like things uncomplicated, no drama. Makes the cold soak method perfect for me. Submerge tobacco in PG and wait, about as easy as it gets.

I placed an order tonight with WL. Now I just have to get some tobacco. The most confusing part of reading NET threads is people stating how many grams or ounces of tobacco they use. If they said a half cup or something that I can visualize it would help. I bought off the shelf pipe tobacco years ago but don't remember how much is in them. Guess I have to buy something, probably ciggy stuff. Don't want any BT additives.
