Claims

1. THE PROCESS OF PRODUCING STABILIZED PRODUCTS OF THE TYPE DESCRIBED FROM RAW OR PREPARED MATERIALS IN A NORMAL LIQUID STATE, SUCH PROCESS COMPRISING THE STEPS OF MOLDING THE LIQUID INTO THE FORM OF A PELLET OF SUBSTANTIALLY PREDETERMINED SIZE BY HEAT TRANSFER FROM THE LIQUID TO ANOTHER MATERIAL BY FIRST DROPPING A PREDETERMINED QUANTITY OF THE LIQUID INTO A CAVITY OF PREDETERMINED SIZE ON THE SURFACE OF THE OTHER MATERIAL TO FORM A GLOBULE, FREEZING THE GLOBULE IN THE CAVITY TO FORM A GLOBULE, THEN REMOVING THE FROZEN PELLET FROM THE CAVITY, THEREAFTER FEEDING THE FROZEN PELLET ONTO A CONVEYOR IN A MANNER TO FORM A RELATIVELY UNIFORM LAYER THEREON, DESICCATING THE PELLET IN SUBSTANTIALLY THE FORMED SIZE WHILE MAINTAINING THE FROZEN STATE THEREOF IN A RAREFIED ATMOSPHERE, AND COLLECTING THE DESICCATED PALLET FROM THE CONVEYOR.
