Aggregate washing systems are described including mechanisms for slurrying, washing and/or dewatering aggregate material.

Aggregate washing systems are described including mechanisms for slurrying, washing and/or dewatering aggregate material.

Systems and methods for cryogenic separation of plant material are provided. A vessel is filled with cryogenic fluid having a temperature at or less than −150 degrees Celsius. Plant material is placed into the vessel via a basket and agitation is provided to the plant material in the vessel for a predetermined time period. Upon completion of the time period, the basket having at least a portion of the plant material is removed from the vessel. Plant particulates separated from the plant material during the agitation settle to the bottom of the vessel. The vessel is drained of the cryogenic fluid, including plant particulates separated from the plant material.

An apparatus for processing aggregate material includes a chassis, a trough mounted on the chassis at an inclined angle, and at least one shaft rotatably mounted within the trough and extending from a lower to an upper end of the trough. The at least one shaft has blades mounted thereon, the blades being angled so that they carry material within the trough towards the upper end of the trough when the at least one shaft is in a normal direction of rotation. A discharge opening is formed in a base of the trough adjacent the upper end of the trough, a weir being provided in the trough upstream of the discharge opening over which processed material must pass to reach the discharge opening.

A Cannabis trichome separator. At least one storage vessels are provided, each vessel having an open top and adapted to receive a plant material and chilled or ice water mixture. A mechanism for agitating the mixture is also provided. Another mechanism raises, lowers, and pivots the agitating mechanism, so the agitating mechanism can be placed over the open top of each of the at least one storage vessels. The mixture can be agitated in each of the storage vessels, seriatim. Also disclosed is a method for processing raw plant material. A plant material and chilled or ice water is introduced into each of at least one storage vessels. The agitating mechanism agitates the mixture in a first of the storage vessels, pivoting the agitating mechanism from a first position to a second position, and agitating the mixture in subsequent storage vessels, seriatim.

Apparatus for cleaning contaminated aggregate includes at least one channel arranged in use to receive a liquid containing contaminated aggregate; and first and second banks or groups of at least one jet. The first bank or group of jets is arranged to direct pressurized fluid at the contaminated aggregate in order to agitate the contaminated aggregate against a surface and promote the separation of cleaned aggregate from contaminated aggregate. The second bank or group of jets is arranged to direct and/or urge the cleaned aggregate to a drainage outlet.

Systems and methods for cryogenic separation of plant material are provided. A method of cryogenic separation of plant material, includes placing a sieve into a vessel. Plant material is placed in the sieve. Cryogenic fluid is provided at or below −150 degrees Celsius to the sieve. The plant material is agitated within the sieve and the vessel to separate plant particulates solidified by the cryogenic fluid from the remainder of the plant material. The cryogenic fluid and plant particulates are removed from the vessel.
