## CPC

- B30B 9/121: {Screw constructions}
- B30B: PRESSES IN GENERAL (producing ultra-high pressure or ultra-high pressure and high temperature to effect modifications of a substance, e.g. for making artificial diamonds B01J3/00 ){(compressing means for refuse receptacles B65F1/1405)}

## Abstract

A low speed seed oil expeller press with the capability of extracting oil through a new seed compression design that eliminates the need for filtration, and maintains the captured seed oil at a temperature below 130 degrees F. It has a seed preheating capability and controls the pressure and extraction oil temperature by adjustments of the expeller speed, the head volume and the size of the pressed seed exit orifice in the thorn. The seed oil expeller press eliminates seed rotation within the head volume so as to eliminate crushing, grinding or tearing of the seed by a symmetrical knived press head. The seed oil expeller press regulates seed temperature, seed feed rate, seed pressure, seed rotation and extracted seed oil temperature so as to compensate for the seed size, seed hardness and seed oil content.

## Claims

### Claim 1

An expeller for a tunable seed oil press comprising:
a body having a cylindrical side wall, a convex proximal end and a distal end;
a flange extending perpendicularly from said distal end of said body, said flange having a planar distal face and a planar proximal face;
a single feed groove helically formed in said cylindrical side wall extending between said proximal face of said flange and said convex proximal end;
a convex proximal end hardened to a Rockwell C scale of hardness of 55-66; and
wherein said convex proximal end has a polished ASTM A480-12, #8 finish formed thereon.

### Claim 2 (depends on 1)

The expeller of claim 1 further comprising:
a taper formed at a perimeter edge of said planar proximal face of said flange.

### Claim 3 (depends on 2)

The expeller of claim 2 further comprising:
a circular cylindrical stopped bore formed parallel to and centrally located around, a linear axis of said expeller, said stopped bore extending inward from said distal end of said expeller and terminating in a cone.

### Claim 4 (depends on 3)

The expeller of claim 3 further comprising:
an internal keyway formed along an internal side wall of said stopped bore for the frictional insertion of a key.

### Claim 5 (depends on 4)

The expeller of claim 4 wherein said helical feed groove has a concave bottom surface with a first width, and a planar top surface with a second width, wherein said second width is less than said first width.
