A highbanker may be used with sluice mats to separate heavier metals from placer deposit. The highbanker includes a hopper assembly, a trough assembly, a brace member, and a plurality of legs. The trough assembly includes first and second trough sections. The first trough section includes a first surface and is pivotably connected to the hopper assembly. The second trough section includes a second surface, with the second trough section being removably attachable to the first trough section. The brace member extends between the trough assembly and the hopper assembly. The plurality of legs is removably attachable to the trough assembly. In an assembled configuration, the second trough section is attached to the first trough section so that the first surface and the second surface define a substantially continuous surface for accepting the sluice mats. In a nested configuration, the second trough section is nested within the first trough section.

A sliding drawer sifter apparatus for sorting plant buds by size includes a frame having a set of drawers comprising a top drawer, a middle drawer, and a bottom draw. Each of the set of drawers has a handle and an inner lip. A set of sifter grates each has a grate perimeter selectively engageable with the inner lip of each of the drawers and a grate body coupled within the grate perimeter. The set of sifter grates comprises a top grate, a middle grate, and a bottom grate. The grate body of the bottom grate is finer than the grate body of the middle grate. The grate body of the middle grate is finer than the grate body of the top grate. The top grate, the middle grate, and the bottom grate are configured to sort progressively smaller plant buds into the set of drawers.

A device for handling seeds and grains, suitable for use in food processing and/or preparation, is disclosed. This device features a semi-spherical bowl with perforations, a wiper that is activated by engaging the handle, and measuring lines on the semi-spherical bowl.

A modular building block sorter comprising: a housing having at least two sides and a base and at least one perforated surface adapted to selectively engage with said at least two sides of said housing, wherein said base comprises a first portion and a second portion and wherein said base is other than substantially planar. In some embodiments the base can include one or more discontinuities.

A mobile sieving apparatus and method for harvesting cannabis pollen and trichomes separates the flowers of a cannabis plant. A large sieve panel, a medium sieve panel, a small sieve panel, and a silk screen panel are arranged in a spaced-apart stacked arrangement inside a harvesting vehicle. The sieved panels have different sized openings to enable passage of corresponding portions of the cannabis plant. The sieve panels are arranged by graduated separation, in which the distance between panels correlates to the size of the cannabis plant components passing through the opening. A harvesting panel has a solid, flat surface, and positions below the sieve panels to catch the pollens and trichomes falling through. The panels are stacked in a harvesting vehicle, sliding onto docking rails that slidably receive the edges of panels. The harvesting vehicle is lightweight to enable manual agitation of the vehicle, and enhance mobility of the panels.
