Abstract

A high speed, high volume fruit sectionizer is comprised of a pair of suction cup conveyors onto which fruit is loaded. The fruit is coupled by means of suction attachment to a first conveyor and carried to a position wherein the opposing side of the fruit is suction coupled to the second conveyor. The fruit is drawn through a halving guillotine and coring blade. The fruit halves are then positioned on scooping and sectioning assemblies. A rotating semicircular hoop blade cuts the fruit meat away from the peel while leaving the fruit meat and peel in place. The separated peel and fruit meat are moved across the scooping and sectioning assembly through a blade assembly which sections the fruit meat. The meat sectioning blade has a first portion which cuts through the peel and fruit meat to establish a first radial extent of the section cut. A following portion of the same blade is provided with a dull edge which completes the section cut of the fruit meat, but is not sharp enough to cut the peel or to cut any portion of the conveyor. The conveyor retains uninterrupted suction attachment with the partially sliced fruit peel and is undamaged by the suctioning blade(s). The fruit meat sections then fall away from the peel, which latter is moved by the conveyor to a disposal position.

Claims

1. The apparatus for extracting at least one chunk of meat from a cut fruit section, said fruit section having a peel and meat therein, comprising:

rigid base, having a straight line defined therein;

at least one slicing blade extending outwardly from said straight line;

a cutting band rotatable about said straight line;

first motive means to cause relative motion between said slicing blade and said fruit sections said first motive means causing said slicing blade to create a linear cut within the meat in said fruit section; and

second motive means to cause said cutting band to rotate through the meat of said fruit section after said cut has been imposed therein.

2. The apparatus as recited in claim 1, wherein said fruit section comprises one half of a fruit, said fruit having an axis, said fruit having been halved by means of a planar cut through the axis thereof, and said slicing blade produces a cut extending from said planar surface to the proximity of the inside of the peel.

3. The apparatus as recited in claim 2, wherein the radius of said cutting band is substantially identical to the maximum radius of the meat of said fruit about the axis thereof.

4. The apparatus as recited in claim 1, wherein:

said rigid base includes a semi-cylindrical member extending along said line; and

said fruit section contains a semi-cylindrical void about the axis thereof, and said first motive means causes said fruit section to move across said rigid base by sliding said semi-cylindrical void along said semi-cylindrical member of said rigid base.

5. The apparatus as recited in claim 1, wherein said slicing blade extends along said straight line and the width of said slicing blade, measured outwardly from said straight line to the outer periphery of said slicing blade, increases from a minimum at the leading edge of said slicing blade to a maximum which is not substantially greater than the radius of the meat within said fruit section.

6. The apparatus as recited in claim 5, wherein the edge of said slicing blade is sharp from its leading edge to a selected distance behind said leading edge, and dull in the portion of said slicing blade in proximity to the region of said blade having its maximum width.

7. The apparatus as recited in claim 6, wherein said slicing blade is substantially symmetric about a line radially outward from said straight line to the point on the periphery of said blade having maximum width.

8. The apparatus as recited in claim 7, wherein the trailing edge of said slicing blade is sharpened symmetrically with the sharpened portion of its leading edge.

9. The apparatus as recited in claim 1, having at least two said slicing blades.
