Yunhai’s AutoSieve works seamlessly with your Max Flow recirculation system to automate the sieving process for ice water hash. Instead of shaking bags and lifting heavy buckets, the vibrating stack of high-quality stainless steel micron screens handles the filtration for you. It streamlines production by removing the most labor-intensive part of washing, so once the cycle is done, all that’s left is to drain, collect, and transfer your hash to freeze dryer trays.
With true absolute micron separation for consistent, repeatable results, the AutoSieve takes hash collection to a new level of speed and ease. It comes standard with five screens — 220µm, 160µm, 120µm, 90µm, and 45µm — and micron sizes can also be customized to match your specific preferences.
Easy hash collection:Makes collecting ice water hash easy—no more hauling or heavy lifting
