Apparatus for forming a cake of compressed plant material, comprising a bottom die having a cylindrical upper portion, an inverted conical lower portion and a post extending vertically upwardly from a small-diameter region of the lower portion, wherein plant material is introducible into a cavity of the bottom die surrounding the post; a top die designed and configured to conform to the cylindrical upper portion and the post and having an inverted conical lower portion with a narrower diameter than a corresponding portion in the bottom die; a power train operable to drive the top die into the bottom die so as to be in pressing relation with the plant material interposed between the top and bottom dies for a sufficient duration to produce a cake of compressed plant material.

A juice pressing machine and methods for pressing juice from a foodstuff includes embodiments having a removable pressing chamber and one or more filters which may be assembled and loaded with macerated foodstuff to form thin layers separated by a pressing plate. Once a juicing operation has been completed, the pressing chamber can be removed from the machine for emptying the pressed filters and solids contents therein. The empty pressing chamber may then be rinsed if needed and reattached to the machine for a subsequent pressing operation with newly filled filter(s). The platen may also be easily removed from the machine for cleaning as desired.

Systems and methods are described for salvaging red blood cells from patients during a surgical procedure. In one general aspect, a system is described for extracting blood from blood-soaked absorbent surgical materials such as surgical sponges, gauze, tape, and the like. The collected blood and fluids from these materials can be transferred to a cell salvage machine for harvesting viable red blood cells for autotransfusion.

Described is a rosin press system for extract rosin (oil) from plant material. The rosin press system includes a cone-shaped male plate and a cone-shaped female plate formed to matingly receive the cone-shaped male plate. The plates can be heated such that when plant material is pressed between the plates, rosin is pressed from the plant material and allowed to drain from a drain hole positioned at the bottom of the cone-shaped female plate.
