I’ve never used a pollen separator! I go with four screens and then clean! But 150 µm is the equivalent of 100 mesh US! And in my opinion 100 mesh is going to let a lot of plant material through with it! Your stuff is Still pretty crumbly suggest a lot of contaminant! The puck doesn’t look bad, but you can make some pretty contaminated stuff into a puck by using a lot of pressure! If cleaned correctly, you should be able to put your clean sift into cellophane and press it by hand with a wine bottle containing boiling water! If it’s quality, it will immediately melt and when you are through rolling the bottle over it, you throw it in the freezer for a few minutes, then pull it out and strip the cellophane off! Then you can work the hash like taffy! It pretty much has the consistency of taffy is all I can come up with! So you work it and fold it and pull it and work it and fold it and pull it and you wind up with full melt hash or close to it! I don’t know the quality of material you are starting with or maybe you are running the separator too long but it looks like you are getting too much contaminant and it needs to be cleaned manually for best results! I’m sorry, man, but that’s the best I can come up with! I have never gotten real top quality by just sifting alone! That gets you in the ballpark, but you still have to clean the contaminant out in my opinion and that requires certain environmental conditions, mainly cold and low humidity! In my book sifting is a winter sport! Maybe someone else will chime in that is more familiar with separators! I know I’m not much help to you, but don’t give up! Sifting and bubble washing requires a lot of material to get anything out the other end! And the condition of that material and the quality of that material can have a huge difference on the results!


help me Mr. wizard!


maybe Gnick we’ll see this and offer an opinion! I use a Loupe to inspect the sift! Makes it easy to see how dirty it is! Or clean!
