EP 3938197

Separation equipment

Europe: granted. Mechanical separation apparatus and optimized flow geometry.

PCT filing

Process technology

International: filed. Process and apparatus for scalable mechanical separation.

The directional-flow geometry in these patents also shortens the rosin's path off the heat and into a seated collection cylinder, an emergent quality benefit of the design, not a claim of the patents themselves. The science of the collection path →

The parchment cone and folded-pouch geometry are likewise described in these granted patents (US 11,040,510 / 11,511,465) as components of the press system. See the parchment write-up →

Filed: In Examination

Patent-Pending Technologies

  • Improved extraction bag geometry (V3.7): U.S. application pending. The fold-over-bottom, side-seam-only, flapless, directional-channel design is engineered to keep flow channels open under load; see the flow-control write-up.
  • Smart agitation water separation system: U.S. application pending.
