DETAILED DESCRIPTION
[0022] Reference will now be made to the accompanying drawings, which at least assist in illustrating the various pertinent features of the presented inventions. The following description is presented for purposes of illustration and description and is not intended to limit the inventions to the forms disclosed herein. Consequently, variations and modifications commensurate with the following teachings, and skill and knowledge of the relevant art, are within the scope of the presented inventions. The embodiments described herein are further intended to explain the best modes known of practicing the inventions and to enable others skilled in the art to utilize the inventions in such, or other embodiments and with various modifications required by the particular application(s) or use(s) of the presented inventions.
[0023] The present disclosure is directed to press devices that are utilized to remove materials such as oils or rosins (hereafter rosin) from plant material using compression and/or heated compression. The press devices are configured to receive plant material between compression plates and compress the plant material to extract rosin. In addition, the press devices are configured to rotate the compression plates from a generally horizontal position to a generally vertical position to allow extracted rosin to drip from the press device onto, for example, a collection plate.
[0024] A first embodiment of a press device 10 is illustrated in
[0025] An actuator or ram 50 is fixedly connected to the upper plate 34 between the brackets 32. The ram 50 may be any actuator that is configured to move a movable plate relative to a stationary plate for the purpose of compressing material there between. IN Various embodiments the actuator may be electric, pneumatic, hydraulic and/or mechanical (e.g., a screw actuator). In the illustrated embodiment, the ram 50 is a hydraulic actuator that includes a cylinder 52 that is fluidly connected to a source of hydraulic fluid such as a pump (not shown). In the present embodiment, the cylinder 52 is threaded and is received in a threaded aperture in the upper plate 34 and secured with a set screw. Other connections are possible. A piston 54 of the ram 50, which moves relative to the cylinder 52 in conjunction with the insertion or removal of hydraulic fluid, connects to a piston plate or press plate 35. Upper and lower platens 44, 46 are attached to the press plate 35 and the lower plate 34, respectively. These platens 44, 46 may be heated and/or cooled as is more fully discussed in a further embodiment. In one embodiment, insulation plates 37, 47 may be disposed between the platens and their mating plate.
[0026] In operation, the piston 54 of the ram 50 extends such that the upper press plate 35 and platen 44 are advanced toward the lower platen 46 and lower plate 36 as illustrated in
[0027] In the present embodiment, the C-shaped brackets 32 are formed from thick metal plates such the brackets are able to withstand significant expansive forces applied between their upper and lower jaws without significant deformation. Of further note, the C-shaped brackets 32 have open sides, which allows rosin compressed out of plant material disposed between the compressed platens to drip out of the press when the press plates/platens are rotated into a vertical orientation. Along these lines, the press 30 is adapted to rotate relative to the stand 20 such that the upper and lower plates 35, 34 and upper and lower platens 44, 46 move from a generally horizontal orientation (e.g.,
[0028] Operation of the device 10 to extract plant rosin includes the following steps. Plant material is typically prepressed with a mold kit (not shown) prior to disposal between the platens of the device. Generally, loose plant material is compacted into a puck of material that will later be compressed. The puck is typically wrapped in a layer of silk or nylon fabric or other similar material with a specific filtering mesh size, and the wrapped again into a plastic layer with no filtering properties that allow directioning of the rosin flow. For instance, the plastic layer may, in one embodiment, be formed from a plastic a bag having three closed edges and one open edge. When the puck is compressed within the bag, rosin is directed out of the open edge (e.g., escape side) of the bag. Accordingly, the escape side of the bag may be positioned within the press such that it faces downward when the press is rotated into the vertical position. Similar directioning may be achieved utilizing an appropriately wrapped plastic sheet. In any arrangement, the puck is positioned between the platens 44, 48 of the press 30, with the escape side facing in the direction that will be rotated downward when the press is rotated. Typically, the platens are pre-heated to a desired temperature, though this is not a strict requirement. The platens are closed together hold the puck in position. The press is then tilted 90 and the remainder of the pressing operation may be performed. That is, the plates/platens are compressed to a desired pressure to expel liquefied rosin from the plant material. The liquid falls into the collection plate, which may by previously cooled or may be actively cooled to at least partially congeal the liquid.
[0029]
[0030] Referring again to
[0031]
[0032] The present embodiment of the device 110 also includes two guide rods or shafts 138a, 138b (hereafter referred to 138 unless specifically referenced). The guide shafts are each connected to the upper plate 134 at an upper end and connected to the lower plate 136 at a lower end. The guide shafts 138 guide the linear motion of the movable platens. In this embodiment, the guide shafts are also tension rods that adding additional reinforcement of the upper and lower plates to expansionary forces. As illustrated, the shafts 138 are round linear motion shafts that extend through apertures in plates, 134, 136. Other embodiments contemplate shafts 138 with different cross-section profiles such as a square configuration and/or different guide structures. In any embodiment, the guide shafts 138 (or equivalent structure) engage one or more platens 144, 146, while allowing these platens 144, 146 to move along the length of the guide shafts 138. More specifically, in the present embodiment, an actuator (e.g., hydraulic ram 50) is operative to advance a movable lower platen 146 and a movable intermediate platen 144 against an upper platen 142. See.
[0033] To permit movement of the movable platens 144, 146, the linear guide shafts 138 interface with linear bearings 143 connected to opposing edges of these platens 144, 146. That is, a first set of linear bearings 143 are connected to the lower platen 146 and a second set of linear bearings 143 are connected to the intermediate platen 144. The linear bearings 143 slide relative to the shafts 138 in a direction parallel to the longitudinal axis of the shafts 138 allowing the intermediate platen 144 and the lower platen 146 to move axially between the lower plate 134 and the upper plate 134.
[0034] As noted, an actuator or ram 50 is operative to move the movable platens 144, 146 against the upper platen 142. The ram 50 is substantially similar to the ram described above in relation to
[0035]
[0036] As shown in
[0037] In further embodiments (not shown) the press 130 may have multiple intermediate platens 144 (e.g., two or more) arranged with various combinations of features discussed above. In this regard, each additional intermediate platen 144 results in adding an additional cavity for compressing additional material. Of note, adding an additional intermediate platen 144, further multiplies the area of compression without increasing the force on the ram.
[0038] As noted above, the brackets 132 connect the press 130 to the stand 120 while allowing the press 130 to be rotated from a generally horizontal position (e.g., see
[0039]
[0040] Of note, positioning of the brackets 132 on the side edges of the plates 134, 136, results in the press 130 having an open front and back that allows material to drip out of the press 130 when the plates/platens are rotated into the vertical orientation. Operation of the device 110 to extract plant rosin includes the following steps. The plant material is prepressed with a mold kit, as described above, to produce partially compacted pucks 180 of material to be processed by the device 110. A first puck or set of pucks 180b, 180d are then positioned between the lower platen 146 and the intermediate platen 144. See
[0041] After the press has been rotated 90 from a horizontal orientation to a vertical orientation the extraction compression procedure may be completed. That is, once the platens 142, 144, 146 are vertically oriented and the extraction pressing procedure may be completed. Specifically, the platens are compressed by the ram 50 driving the piston 54 against the lower platen 146, which translates the force generated by the ram 50 through all of the platens until a desired pressure is achieved between the platens. When the platens 142, 144, 146 are compressed together to the desires pressure, liquid rosin is expelled rosin from the plant material. The liquid falls below the press 130 into the open area between the legs 124. A plate, which may be cooled, is placed between the legs 124, under the press 130, to catch the expelled liquid.
[0042] As previously noted, any or all of the platens may be heated to facilitate the removal of extracts from the compressed plant material.
[0043] To control the operation of the heaters 164, the platen 146 further includes a cylindrical thermocouple recess 166, which houses a thermocouple 168. The thermocouple 168 generates an output indicative of the temperature of the platen 146. This output may be received by a control panel 182 of the device 110, which may include a temperature control. Accordingly, a user may adjust the temperature of the platens. Along these lines, it will be noted that different plant materials may require different temperatures for effective processing. Though discussed as utilizing a thermocouple, it will be appreciated that any heat sensor may be utilized.
[0044] Variations may be made to the presented device. For instance, various sensors (e.g., weight sensors) may be incorporated into the collection plate to determine when fluid/rosin ceases dripping onto the plate. Accordingly, an output (e.g., alarm) may sound alerting a user that extraction is complete. Further, various control systems and motors may be incorporated to allow for automated operation of the device. In such an arrangement, after a user loads a puck into the device, the user may simply start the device and the initial compression, rotation secondary compression and collection of resin may proceed automatically.
