ABSTRACT:
A granular, biodegradable carrier made from a naturally occurring cellulose material such as corncobs, wood shavings or saw dust, rice hulls, peanut shells and pecan shells. A maximum density cellulose carrier product is produced in a wide variety of granule size ranges by the process of reducing the cellulose material to produce an intermediate pulverulent product, compressing the intermediate pulverulent product to produce pellets, shearing the pellets to produce the granular product, and classifying the granules to the desired size range. Critical control of a moisture addition to the intermediate pulverulent product before it is compressed or pelletized along with selective tempering of the pulverulent product before compression yields a maximum density pellet and a maximum density granular product.
