Stainless steel sieve vs bags

I see quite a few people running Low Temp’s nest with bags instead of their autoseive. Id think if someone had the capital to back an osprey and nest, theyd be able to swing the autoseive as well. Does anybody here have experience with one? Is there some con I’m not seeing?

A few hundred for a set of bags is cheaper and does the same

I have a nest and bought the auto sieve and was quite disappointed with the inconsistency’s in micron size and the microns it came with vs a normal set of bags from any of the big brands

Can you expand upon this? Interested to hear the details regarding

Would love to hear more about the sieve vs bags

Basically the sieve sizes were not accurate. For example the 160 screen should let everything pass through except 160u or bigger. After doing side by side test with brand new rosin evolution bags we could clearly see with multiple microns that it was not accurate. We tested this by re running the hash in each collected area through rosin evolution bags again to see what came through. Small amounts wouldn’t concern me but what we saw definitely concerned me enough to never use the sieve and stick with bags.

For the record: that merely tells you the sizes don’t match.

It does NOT tell you which is more accurate.

You might even be dealing with “mesh” vs “micron”.

I suggest you get a microscope . See maybe: USB Microscopes so you can compare them.

If you really want to know which is more accurate, the machine shop at your local university probably has the correct tooling.

Specialized Tools

  • Linear Mesh Counters (PIC Gauges): These are specialized hand-held magnifiers with a built-in calibrated scale used for quick, on-site measurements of mesh count.
  • Optical Comparators/Profile Projectors: These project a magnified image of the mesh onto a screen or sensor for detailed measurement and quality control, especially in an industrial setting.
  • Densi Meters (Lunometers): These instruments use an optical phenomenon (moiré patterns) to quickly determine the thread count or density of a mesh.

It’s even possible that it is the material rather than the actual pore size that is responsible for the difference you’re seeing…

I guess I should add that I’m basing my opinion off what makes the best hash and not what is true micron size. My only concern is quality so that was the decided factor for me if the 160 µm for example is letting through heads into my 90 U and that is a problem for me.

Totally valid…AND understanding exactly how shit is broken often goes a long way towards fixing it.

Did you provide feedback to the OEM?

Would one not expect ALL heads to pass through 160um?

Are you referring to that which sits ON your 90um bag as 90u? Because that’s the only way I can make sense of “160um letting through heads into my 90U”.

90U should be that what passed through 90u but failed to pass through next smaller screen. Eg if that’s a 70um then “90u” should be stuff between ~70 & 90um.

If you’re going 160=>90 and calling what’s on the 90u screen “90u”, let me reiterate that you expect everything between 160um and 90um on there. Which (should) will only contain heads if they are still attached to the stalk or are exceptionally large

IMO everything you’re after SHOULD pass through the 160um….and your 90um…so blaming your 160 for your 90 “having heads in it” seems strange.

The cannabis industry needs people like you. Not a pure scientist but RESULT oriented. why doest any weed sold in Illinois have intact trich heads? I can bounce it on a black sheet and no trichs fall off? DAMMIT

I am in total agreement…I can not make any sense out of what that post means. (@DabmasterDon) 160u should retain perhaps stalks with out heads, if they are not already in the 220u bag. Cold ice wash that is. ??? If you are working in this field operators should buy yourself a High Quality binocular microscope.(Nikon, Olympus, Zeiss) and fiber optic illumination. And for your system, method of harvesting, and all variables…take a close look at what goes into the Ice wash, and then inspect each bag down to 40u and classify what you are looking at, each strain, each harvest each lot. ..Including and especially the biomass bulk. Expect different outcomes for outdoor product vs indoor and strains., The bulk biomass, that does not go any where , retains upwards of 50% of your cannabinoids..form my estimations…??? Do not be surprised at low yields compared to the biomass material COA. ( @ cyclopath..This is just meant as a directive to the forum. I’m just adding a bit more to your astute observations.)
