A plant press including a container having a cavity for receiving a plant and a plunger disposed within the cavity of the container. The plunger being translatable in a direction transverse to a longitudinal axis of the cavity and adapted to create a shearing force.

Some variations provide an automated system for solvent extraction of a feed stock to produce a botanical extract, fats, oils, or other desirable solute, comprising: an extraction reactor; a distillation unit; and a second-stage purge chamber or a second-stage purge process utilizing the extraction reactor itself. The second-stage purge chamber or process receives or holds the solid material along with a heated inert non-condensable gas and/or solvent vapor, to recover residual solvent contained in the solid material. Other variations provide a process comprising: feeding a raw material and a solvent into an extraction reactor; generating dissolved material in rich solvent and extracted solid material; distilling the rich solvent to generate purified product and recovered solvent; conveying the solid material and a heated inert non-condensable gas and/or solvent vapor into a second-stage purge chamber, or holding the solid material in the same vessel, to recover residual solvent; and recovering the purified product.

A copper/molybdenum separation system uses sea water in the roughing circuit and desalinated water in cleaning circuit. In both roughing circuit and cleaning circuit, hydrophobic engineered media are used to recover the mineral particles of interest. The cleaning circuit includes a molybdenum loading stage configured to contact the conditioned pulp with the engineered media in an agitated reaction chamber, and load the hydrophobic molybdenite on the engineered media.

The system and method of the present invention provides an automated washing and extraction system and method to removed trichomes from cannabis product to create hash resin. Inconsistency is removed from the hash extraction process by automating the washing and extraction cycles thereof. The system and method records the data and tracks all user functions. Manual labor is removed or significantly reduced and time to create the final product is greatly lessened. Thus, more hash can be produced in a shorter amount of time. Moreover, the present invention allows the end user a controlled and accurate and efficient way of producing large quantities of solvent-free hash in a short amount of time while doing so in a consistent, repeatable and cost-effective manner.

A solvent based cannabinoid extraction process and apparatus that retains the flavonoids and terpenes by using low temperature, high surface area inline filtration, vacuum distillation, homogenization and pasteurization to produce a superior finished product.

An apparatus for washing and decontaminating soils includes a high-pressure microbubble generation module, a coarse grain heterogeneous separation module, an ultrasonic shock module, and a fine grain heterogeneous separation module. The high-pressure microbubble generation module generates first microbubbles, and uses a first shock energy generated when the first microbubbles burst to remove an oil contaminant on coarse grain soils. The coarse grain heterogeneous separation module uses the difference in density to separate the oil contaminant and the coarse grain soils from a soil and water mixture. The ultrasonic shock module generates second microbubbles and performs an ultrasonic shock operation to increase a second shock energy generated when the second microbubbles burst to remove another oil contaminant on fine grain soils. The fine grain heterogeneous separation module uses the difference in density to separate the another oil contaminant and the fine grain soils from the soil and water mixture.

The present invention provides a process for fractionating biomass into its individual components. The process includes pretreating a biomass which may include mechanically altering the fibers and/or contacting the biomass with a solvent to provide a fluidized biomass. The pretreated fluidized biomass may be subjected to high frequency pulses and shear forces without denaturing one or more components of the biomass to provide a first liquid fraction and a first fractionated biomass. The first liquid fraction may then be isolated or separated from the first fractionated biomass. The biomass may be separated, isolated or purified into lignin, extractives for use in pharmaceuticals or nutraceuticals, cellulose, hemicellulose, and other sugars and proteins.
