  • Publication number: 20240409966
    Abstract: Systems and methods are described for processing a plant material, such as cannabis and/or hemp. An example method includes: providing a slurry of plant material; providing an inert gas; adding the slurry and the inert gas to a tank; applying heat and pressure to the slurry inside the tank to generate a processed plant material; removing the processed plant material from the tank; and drying the processed plant material in a dryer to produce a dried product comprising cannabidiol (CBD).

  • Patent number: 10124962
    Abstract: A roll-formed steel slat for use in a reciprocating floor slat conveyor system. The roll-formed steel slat is formed in a manner so as to have an upper, load-carrying surface, and a pair of downwardly depending side legs. Each side leg terminates in a foot. One foot is vertically offset from the other to provide a “hold-down” function that prevents the slat from vertically rising as the slat reciprocates back-and-forth.

  • Publication number: 20180222684
    Abstract: An all-aluminum cross-drive member for a drive unit assembly that is used to reciprocate floor slats back and forth in a conveyor system, The cross-drive member is extruded or milled from a single piece of aluminum, One side of the member carries connecting pieces for linking the member to floor slats, with the member driving the floor slats back and forth as the member is likewise moved lengthwise in back and forth movement, The other side of the member has stiffening ribs that extend lengthwise for giving the member sufficient stiffness to carry loading forces in lieu of the steel cross-drives used in the past.
