Abstract

The present disclosure relates to the processing of hops. More specifically, an apparatus and method for extracting lupulin from hops are disclosed. Hops are brought into contact with a cooling agent, such as dry ice, to freeze or cool the hops. This cooling is facilitated by mixing the hops and the dry ice together inside of a tumbler. The tumbler continuously rotates to mix the dry ice and hops. Further mixing is afforded by an internal agitator that sweeps the interior of the tumbler. The agitator also pulverizes the hops and separates the hops from the particulate lupulin material. The tumbler is formed from a mesh material that allows the extracted lupulin to leave the tumbler and be collected.

Claims

1. An apparatus for extracting lupulin from hops, the apparatus comprising:

a rectangular frame for supporting the apparatus upon a surface, the frame including an upper peripheral extent;

a cylindrical tumbler adapted for rotation with respect to the frame, the tumbler including an interior area, opposing ends, and an intermediate extent, mounting plates secured at the opposing ends, a mesh screen extending between the mounting plates, the mesh screen allowing particles of between approximately 200 to 1000 microns to pass therethrough, a central axle rotatably mounting the tumbler to the peripheral extent of the frame, a door formed within the mesh screen to provide access to the interior of the tumbler;

a volume of hops and particulate dry ice positioned within the interior area of the tumbler, the dry ice functioning to cool and abrasively contact the hops and thereby facilitate the separation of the lupulin from the hops;

an agitator positioned along the central axle of the tumbler and positioned within the interior area, the agitator including a series of arms that functioning in sweeping the interior of the tumbler and further separating the lupulin from the hops;

a motor powering both a tumbler drive train and an agitator drive train, the tumbler drive train rotating the tumbler at a first rate of rotation, the agitator drive train rotating the agitator at a second rate of rotation, with the second rate of rotation is substantially greater than the first rate of rotation;

a collector positioned about the tumbler and functioning to collect the lupulin passing through the mesh screen.

2. An apparatus for extracting lupulin from hops comprising:

a tumbler including an interior, a screen, and an axle for rotatably mounting the tumbler;

a volume of hops and particulate frozen matter positioned within the interior of the tumbler, the frozen matter functioning to cool and abrasively contact the hops and thereby facilitate the extraction of the lupulin;

an agitator positioned within the interior of the tumbler, the agitator mixing the hops and frozen matter and separating the lupulin from the hops;

a motor powering both the tumbler and the agitator;

a collector positioned adjacent tumbler and functioning to collect the lupulin passing through the screen.

3. The apparatus as described in claim 2 wherein the tumbler is cylindrical and the axle is centrally mounted.

4. The apparatus as described in claim 2 wherein the frozen matter is dry ice that is broken down into pieces of between ½

inch and 3 inches.

5. The apparatus as described in claim 2 wherein the screen allows for the passage of particles having a diameter of approximately 200 to 1000 microns.

6. The apparatus as described in claim 2 wherein the tumbler and agitator rotate in opposite directions.

7. The apparatus as described in claim 2 wherein the agitator rotates at a rate of between approximately 500 and 2000 RPMs.

8. The apparatus as described in claim 2 wherein the tumbler rotates at a rate of between approximately 1 and 60 RPMs.

9. The apparatus as described in claim 2 further comprising a door positioned within the tumbler to gain access to its interior.

10. A method of using dry ice to extract lupulin from hops, the method comprising the following steps:

breaking the dry ice into smaller particles;

combining the dry ice particles and the hops, the contact between the dry ice particles and hops decreasing the temperature of the hops;

agitating the dry ice particles and hops, whereby the dry ice particles abrasively contact the hops and the lupulin is extracted from the hops;

passing the extracted lupulin through a mesh screen whereby the lupulin is separated from the remaining hops materials;

collecting the screened and extracted lupulin.
