Dry sift setup

[Labrat1987]

Hi there,

I have a boatload of unsifted kief that i am going to sift down to 160 & 75 micron. Any suggestion for a dry sifting kief screen? i am looking for a large scale setup to do several pounds at a time.

If you have a ton of “dirty” kief, I would suggest a small shop vac attached to a foot pedal for a power switch. Place a bubble bag on the vacuum hose and just use short bursts of vacuum to clean up the kief. It works best to have it in a deep walled container spread really thin.

Have you done this before? if so, how well does this work?

try getting a Hogentogler sieve shaker and a stack of stainless test sieves: i’d say 22u + 75 + 160u + 240u should give you two good cuts (fine and extra fine) 12" is the larger size, could handle lbs per hour
extra trays add volume, batch capacity
the 22u will pass dust and undersirables out from your extra fine sift

I’m old school, but found kitchen grade stainless steel, supplier. I’ve found that 120 micron screen was the sweet spot screen size. I would make drums, 5 gallon, up to 55 gallon trammal. Spin at 18 rpm +/- 4 rpm.

Here is link for TWP.

I’ve seen stackable bucket micron filters like dudadiesel sells and they place them on top of a vibrating she’ll cleaner.

The foot petal is essential, u litterly wanna just tap it quick. Have a brush on you and ur gonna be holding it about 1-2" above the pile.
20-40micron screen works well

Pulse it on. Brush it off.
Repeat.
