Abstract
Abstract MEAL WHICH IS TO BE PELLETED IS INTRODUCED INTO A PRESSURE CHAMBER WHERE A PREDETERMINED AMOUNT OF MOISTURE IS ADDED TO THE MEAL AS IT IS AGITATED AND ADVANCED THROUGH THE CHAMBER. THE MOISTENED MEAL IS HEATED IN THE CHAMBER TO A PREDETERMINED TEMPERATURE AND RETAINED THEREIN FOR A SUFFICIENT LENGTH OF TIME TO EFFECT DESTRUCTION OF SUBSTANTIALLY ALL THE BACTERIAL ORGANISMS IN THE MEAL WITH A MINIMUM DESTRUCTION OF THE NUTRITIONAL VALUE OF THE MEAL BY AVOIDING COOKING. PELLETING IS ACCOMPLISHED BY A RINGTYPE PELLET MILL WHICH AUGMENTS SAID DESTRUCTION WITHOUT COOKING.
