(10) In a preferred embodiment, the system for rosin extraction 100 comprises a press ram 14, wherein the press ram 14 includes an adjustable shank rod 1, wherein the adjustable shank rod 1 is connected to an adjustable rod mating tube 4. In one embodiment, a lock rod 2 with a corresponding lock handle 3 is located on the adjustable rod mating tube 4 to allow for the variation of the height and depth of the adjustable shank rod 1 during operation. Furthermore, a top press disk 5 with an associated O-ring 12 is connected to and located beneath the adjustable rod mating tube 4. A pressure vessel 6 with an associated pair of handles 13 sits below the top press disk 5, wherein the pressure vessel 6 preferably stores the material utilized in the extraction process.

(11) Additionally a filter 7 is disclosed in connection with the pressure vessel 6 to allow for the filtration of the desired material during the extraction process while preventing any unwanted elements from moving through the system 100. A bottom press disk 8 is used for material extraction and contains the filter 7 between the pressure vessel 6. Furthermore, a bottom heat plate 9 is located below the bottom press disk 8, and a plurality of insulation disk 10 are located below the heat plate 9. Finally, a cooling plate 11 may be placed at the bottom of the system 100.

(12) In certain embodiments, the system for rosin extraction 100 may be configured for use with a number of press systems, including, but not limited to an electric drive press, air or pneumatic press, air-over-oil press, or a full hydraulic press (see FIG. 2). Ideally, the press may be any type of press, wherein the force cycle and the cycle initiation may be controlled by the user.

(13) In one embodiment, the pressure vessel 6 is a heated chamber. In a preferred embodiment, the pressure vessel 6 is an appropriate size in order to accommodate the top press disk 5. In yet another preferred embodiment, the pressure vessel 5 should also be able to accommodate the attachment of the filter 7. The filter 7 is preferably constructed from a material suitable to withstand the force of the press ram 14. The filter 7 in some embodiments may comprise a filter disk-like plate. Further, in some preferred embodiments, the filter 7 may assist in the material handling of the rosin for selling purposes in order to avoid contamination and the use of unnatural bagging systems. The filter 7 may be attached to the pressure vessel 6. In a preferred embodiment, the filter 7 may be perforated to allow for the extraction of the rosin substance; the filter 7 may also be used to seal the pressure vessel 6. Additionally, a collection bin 15 may be provide for storage of any extracted material following the extraction process. The storage of the extracted material in the collection bin 15 may be accomplished via individual cups, a drip tray or other similar systems.

(14) In preferred embodiments, the rosin collection device is removable, portable, storable, containment device. After the rosin is extracted, the end product may be packaged through a bag-less system in order to preserve the organic qualities of the final rosin product.

(15) FIG. 2 illustrates a diagrammatic perspective view of the system for rosin extraction 100 configured for use with a standard press assembly 20. In this embodiment, the rosin extraction system 100 is maintained within an H frame 22 and a pneumatic press 24 located above the H frame 22. Additionally, a programmable touch screen interface 26 is provided and attached to the H frame 22 to enable a user of the system to configure a variety of operational parameters (see FIG. 3) depending on the specific extraction process desired.

(16) FIG. 3 illustrates a flow diagram of one embodiment for rosin extraction utilizing the system for rosin extraction 100. In certain embodiments, the system 100 may function by a user first inputting necessary operating parameters via the touch screen interface 26. For instance, the user may set the desired temperature, pressure (force applied), and time. With each use, the user may desire differing temperatures, pressures, and times, in order to achieve the preferred product and vary the parameters via the touch screen interface 26.

(17) Initially, at step 40, a user sets the desired parameters of temperature, pressure and heat for operation of the rosin extraction system 100. Alternatively, the user of the system may select a predetermined recipe (pre-set parameters) via the touch screen interface 26. Following selection and inputting of the operating parameters, at step 42 the pressure vessel 6 is locked into place via a pair of L brackets on either side. Next, at step 44, a quantity of material for extraction is loaded into the pressure vessel 6. Following the loading of material, at step 46 the lock rod 2 is removed to adjust the height of the press ram 14 in order to secure the top press disk 5 into the pressure vessel 6. At step 48, a pre-press and pre-heat process is undertaken to both compact and heat the material for extraction. In one embodiment, during the pre-heat/pre-press process in step 48, the purpose is to compress and densify the material for extraction in order to achieve uniform and fast heat transfer. One example of this process may involve the press ram 14 actuating to a certain position/pressure while the material is being heated. It is important to note that no actual extraction occurs at this step, but rather it assists in the preparation for an ideal extraction process.

(18) Subsequently at step 50 the pressure vessel 6 is heated to the desired temperature set during step 40 and then pressure to the desired pressure also set at step 40. Lastly, at step 52 the extracted rosin is collected and stored.

(19) In one embodiment, the three main parameters during the extraction will be the temperature of various elements in the system 100, the amount of force applied to the pressure vessel 6 by the press ram 14, and the time of the material being exposed to the desired temperature and force. In one embodiment, the O-ring 12 and the bottom heat plate 9 will each have a temperature setting in the range between 0-375 degrees Fahrenheit, and more particularly in a range between 190-225 degrees Fahrenheit. Additionally, the cooling operates in a temperature range between 0-70 degrees Fahrenheit. In yet another embodiment, force applied by the press ram 14 is in the range between 0-120 Tons, however depending on the specific application, one may envision utilizing a greater force above the high end of the stated range.

(20) As stated above, a user of the system 100 has the option to either input the settings for each parameter, or alternatively, the user may choose from various programmable recipes including, but not limited to:

(21) 1. Static: Single static press applied. Ideal for small batches.

(22) 2. Pre-Press Static: Single static pre-press applied then a single high pressure full press. For compacting higher volumes and minimizing blowout.

(23) 3. Pre-Press Ramp: Pre-Press applied then incrementally increase to high pressure full press. Optimized for densifying low water content material while minimizing blowout. Ideal for hash.

(24) 4. Pre-Press Liquification: Static pre-press applied then increases to high pressure frequency cycling. Provides the best extraction yields for high volumes.

(25) 5. Custom: Customizable force curve with fully programmable sequences of pressure, temperature and Time

(26) All of the methods stated above may be programmed with Force loop-back controlsthis feature may determine the optimum squeezing time based on the force drop-off as rosin is expressed. The escaping rosin causes the applied force to drop-off, the machine will monitor and adjust the force incrementally, until the drop off is below a set threshold to represent the point at which the remaining material has reached max densitythus expelling the most rosin achievable under the programmed conditions. Sending a machine complete signal to allow operator to proceed with next batch.

(27) In some embodiments, when controlling the force, the user may wish the force to be pre-press, high pressure, ramping, pile driving (liquefy), or static, again depending on what the user wants as the end product. Time may be adjusted in certain embodiments to include prepress dwell, static delay, static dwell, ramp step duration, ramp step delay, liquefy dwell, and liquefy delay. In certain embodiment, temperature may be adjusted to hold, soak, energize, limited to the top plate, limited to the bottom plate, or collar. Other additional controls the user may be able to manipulate include the vacuum to assist the rosin extraction pump, wherein the user may adjust the vacuum in order to draw out the extracted rosin into a holding/collection vessel at room or cooled temperature to maintain the product's purity.

(28) It should be understood that various alternatives to the embodiments of the disclosure described herein may be employed in practicing the disclosure. Elements of an implementation of the systems and methods described herein may be independently implemented or combined with other implementations. It is intended that the claims to follow with the utility application define the scope of the disclosure and that systems, methods, and devices within the scope of these claims and their equivalents be covered thereby.
