A filter extractor may include a first gutter fixed to a tool body and a second gutter being pivotably connected to the tool body. Additionally, a lifting device may be provided on the filter extractor. The lifting device is configured to extend and retract a line through the first gutter and the second gutter to extract a filter from a fluid conduit.

A bar-type screen cage has profiled screen bars which are spaced apart in a circumferential direction. Multiple support arrangements which are spaced apart in an axial direction of the screen cage are fastened by welding to the profile bars at the outside. The screen bars, which are spaced apart in an axial direction, form screen slots between them. Each support arrangement includes at least two support wires which are closely spaced apart in the axial direction of the screen bars and which are fixed to the screen bars by resistance welding. The two support wires of each support arrangement and the profile bars-are fixedly connected to one another by way of an additional weld seam.

A rotary separation apparatus is deployed in a process for separating resinous trichomes rich in flavoring, aromatic and/or medicinal components produced in plant trichome glands from unwanted plant matter. A liquid freezing agent is introduced into a container of the plant matter to fragment the undesirable matter while the desired portion rich in trichome remain intact.
