Apparatus and method for separating plant trichomes using a double vortex turbulence
A method and apparatus for separating trichome heads containing resin from cannabis plants using a double vortex liquid flow to remove the trichome heads without macerating the plant material and a multi-tiered filtration process to isolate the resin product.
1. An apparatus for separating trichome heads containing resin from plants using liquid, the apparatus comprising:
a basin comprising a D-shaped tub when viewed from above, a cover at a top of the basin, a bottom that is flat, a front portion that is semi-cylindrical along a vertical axis, a back portion that comprising a rounded box having two rounded corners extending in a vertical direction, a radial distance from a center of the semi-cylindrical front portion to a flat portion of the rounded box back portion is equal to or greater than a radius of the semi-cylindrical front portion;
a rotator plate located inside and exclusively adjacent to the bottom of the basin, the rotator plate is circular, flat and has a vertical axis of rotation with a top surface comprising ribs extending vertically therefrom;
a motor that is reversible and coupled to a bottom of the rotator plate, such that when the basin contains liquid and plant material and the rotator plate rotates, a double agitation is configured to form in the liquid comprising a first vortex about the vertical axis of rotation, and a second agitation adjacent to alternating ones of the two rounded corners of the basin, depending on a rotational direction of the rotator plate;
a cart, the basin is mounted on top of the cart, the motor is vertically below the basin, and a filtering system extends out of and is located on a side of the cart below the basin; and
a control panel configured to automatically control the apparatus and reverse a rotational direction of the rotator plate at selected intervals, and the control panel is configured to automatically increase a speed of the reversible motor during operation.
2. The apparatus of claim 1 , further comprising:
a drain in the flat bottom coupled to the filtering system comprising a valve and two or more removable filters in series such that, when the valve is opened and the liquid is drained from the basin, processed plant biomass and trichome heads containing resin are captured in the filters; and
a cooling jacket on the basin configured to regulate a temperature of the liquid, and tops of the ribs on the rotator plate are located vertically below the cooling jacket.
3. The apparatus of claim 1 , wherein the control panel is configured to automatically increase a speed of the reversible motor during operation, and the speed is in a range of 300 rpm to 1700 rpm.
