Centrifuges

A system, comprising:

• a solvent vessel configured to store a solvent at a controlled temperature for use in extracting products from a quantity of biomass;
• a centrifuge, comprising:
• a basin configured to contain the solvent and a residual amount of the quantity of extracted products and comprising a drain;
• a rotor connected to the basin and configured to rotate a circular basket;
• a solvent inlet connected to the solvent vessel and configured to selectively permit inflow of the solvent into the basin;
• a lid connected to the basin via a hinge and configured to selectively close a top opening of the basin;
• the circular basket disposed within the basin, the circular basket comprising:
• a basket wall;
• a perforated solvent distributor disposed along a longitudinal axis of the circular basket;
• and
• four perforated baffles disposed within the circular basket and connected to the perforated solvent distributor, wherein the four perforated baffles are configured to define four quadrants within the circular basket and force a quantity of cannabinoid resin through the solvent;
• and
• wherein:
• the circular basket is configured to receive a bag containing at least a portion of the quantity of the biomass;
• the centrifuge is configured to spin the contents of the basket to effect a separation of constituent products from the biomass for processing;
• and
• the system further comprising:
• a filter configured to permit passage of the solvent but not of a biomass constituent;
• a solvent cooling vessel and/or a warming vessel configured to control the solvent temperature;
• and
• a pump configured to pump the solvent into the solvent vessel for reuse.
