Abstract
Abstract Homogenized whole, fresh, green bone, cooked or uncooked, or animal or fish or shellfish calcareous material, useful as a mineral and protein food supplement suitable for animal and human consumption is prepared by supplying such material in particle form and containing the normal inorganic and organic constituents thereof to a pan, the surface of the pan moving relative to a heavy rotatable wheel positioned above or on the surface of said pan, e.g. a pan crusher, the particle form material being supplied to said pan so as to come under said wheel as it moves relative to the surface of said pan to crush the particle form material between the wheel and the surface of the pan to a particle size below about 10-50 microns, more or less, and recovering the resulting crushed material.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
114 words
A METHOD OF PREPARING A FOOD PRODUCT USEFUL AS A PROTEIN AND MINERAL FOOD SUPPLEMENT SUITABLE FOR ANIMAL AND HUMAN CONSUMPTION WHICH COMPRISES SUPPLYING PARTICLE-FORM ANIMAL BONE OR OTHER ANIMAL, FISH OR SHELLFISH CALCAREOUS MATERIAL TO THE SURFACE OF A PAN, THE SURFACE OF SAID PAN MOVING RELATIVE TO A HEAVY ROTABLE WHEEL POSITIONED CLOSELY ABOVE OR ON THE SURFACE OF SAID PAN, THE PARTICLE-FORM MATERIAL BEING SUPPLIED TO THE SURFACE OF SAID PAN SO AS TO COME UNDER SAID WHEEL AS IT MOVES RELATIVE TO THE SURFACE OF SAID PAN TO CRUSH THE PARTICLE-FORM MATERIAL TO A PARTICLE SIZE BELOW ABOUT 50 MICRONS AND RECOVERING THE RESULTING CRUSHED MATERIAL AS SAID FOOD PRODUCT.

Claim 15
Independent Claim
142 words
A method of preparing a food product useful as a mineral and protein food supplement suitable for animal and human consumption which comprises breaking animal bone containing the normal inorganic and organic constituents thereof to a size of about 1 inch, further reducing the size of the resulting broken animal bone to a size of about 1/8 inch, thereupon reducing the bone to a particle size of about 200-300 microns, supplying the thus-treated animal bone to a pan, the surface of said pan moving relative to a heavy rotatable wheel positioned above said pan surface, the thus-treated bone being supplied to said pan so as to come under said wheel as it moves relative to the surface of said pan to crush the bone to a particle size below about 10 microns and recovering the resulting crushed bone as said food product.
