Abstract
Abstract A method of making animal litter consisting of grinding peanut hulls into a size that will allow the ground hulls to pass through a one-sixteenth to a one-half inch sieve. Mixing the ground hulls with a ground vegetable product such as alfalfa, broom grass, or a like product containing chlorophyl to give the mixture not less than one percent chlorophyl content. The mixture is subjected to a steam bath to moisten and soften the hulls and the added product which are then forced through a die to form the mixture into small pellets. The moisture in the pellets is reduced by heating as they pass through the die thereby removing at least eighty percent of the moisture.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
107 words
A method of making pelleted animal litter comprising: a. grinding peanut hulls to a particle size which will pass through a sieve of one-sixteenth to one-half inch; b. mixing said ground hulls with a chlorophyl-containing material in an amount to give the mixture a chlorophyl content of substantially one percent; c. heating said mixture with steam to soften and saturate said mixture with moisture into a pliable continuous state, and d. forcing said heated mixture through appropriate dies wherein said mixture in passing through and from said dies is thereby formed into dry pellets having a density of three to six times that of loose peanut hulls.
Claim 2
Independent Claim
107 words
A method of making pelleted animal litter comprising: a. grinding peanut hulls to a particle size which will pass through a sieve of one-sixteenth to one-half inch; b. mixing said ground hulls with a chlorophyl-containing material in an amount to give the mixture a chlorophyl content of substantially one percent; c. heating said mixture with steam to soften and saturate said mixture with moisture into a pliable continuous state, and d. forcing said heated mixture through appropriate dies wherein said mixture in passing through and from said dies is thereby formed into dry pellets having a density of three to six times that of loose peanut hulls.
Claim 3
Dependent Claim
29 words
The method of claim 1 wherein the chlorophyl-containing material in step (b) is a natural carrier of chlorophyl selected from the group consisting of alfalfa, broom grass and straw.
