Method for manufacturing shortening

Claim 1

THE METHOD OF CONVERTING LARD INTO A HIGH-RATIO SHORTENING WHICH COMPRISES CONTAINUOUSLY INTRODUCING THE LARD INTO A CLOSED SYSTEM AS A FLOWING STREAM AND, WHILE IN SAID CLOSED SYSTEM, PERFORMING THE FOLLOWING STEPS SUCCESSIVELY, NAMELY, MIXING AIR WITH A STREAM OF MOLTEN LARD, PUMPING MOLTEN LARD-AIR MIXTURE INTO A COOLING WORM AT HIGH PRESSURE, PASSING THE LARD-AIR MIXTURE THROUGH A CHILLING VESSEL AT HIGH PRESSURE AND SUBJECTING IT TO AGITATION AS IT PASSES THROUGH THE CHILLING VESSEL, SAID LARD-AIR MIXTURE BEING REDUCED IN TEMPERATURE WITHIN THE CHILLING VESSEL TO SUCH AN EXTEND THAT IT LOSES ITS LIQUIDITY AND IS REDUCED TO THE VISCOSITY OF A FREE-FLOWING PASTE, PASSING THE CHILLED LARD-AIR MIXTURE THROUGH A FIRST AGITATOR AT HIGH PRESSURE AND BEATING IN THE ENTRAINED AIR TO PRODUCE A SUBSTANTIALLY SMOOTH LARD-AIR DISPERSION, FORMING A HOT AQEOUS DISPERSION OF ANIMAL PHOSPHATIDES, COLLOIDALIZING THE AQUEOUS DISPERSION TO FORM A SMOOTH AQUEOUS EMULSION, KEEPING THE EMULSION WARM, PUMPING THE WARM EMULSION TO FORM A FLOWING STREAM THE VOLUMETRIC RATE-OF-FLOW OF WHICH IS PRECISELY PROPORTIONATE, AT SELECTED RATIO, TO THE VOLUMETRIC RATE-OF-FLOW OF THE LARDAIR MIXTURE INTO THE COOLING WORM, INJECTING THE PROPORTIONED FLOW OF THE WARM EMULSION AT HIGH PRESSURE INTO THE FLOURING STREAM OF THE LARD-AIR DISPERSION, TRANSMITTING THE EMULSION-DISPERSION MIXTURE THROUGH AN EXTRUSION CHAMBER IN WHICH THE STREAM IS RENDERED TURBULENT, AND PASSING THE EMULSION-DISPERSION MIXTURE THROUGH A SECOND AGITATOR TO PRODUCE A SMOOTHLY EMULSIFIED SHORTENING.

Claim 2

THE METHOD OF CONVERTING LARD INTO A HIGH-RATIO SHORTENING WHICH COMPRISES CONTAINUOUSLY INTRODUCING THE LARD INTO A CLOSED SYSTEM AS A FLOWING STREAM AND, WHILE IN SAID CLOSED SYSTEM, PERFORMING THE FOLLOWING STEPS SUCCESSIVELY, NAMELY, MIXING AIR WITH A STREAM OF MOLTEN LARD, PUMPING MOLTEN LARD-AIR MIXTURE INTO A COOLING WORM AT HIGH PRESSURE, PASSING THE LARD-AIR MIXTURE THROUGH A CHILLING VESSEL AT HIGH PRESSURE AND SUBJECTING IT TO AGITATION AS IT PASSES THROUGH THE CHILLING VESSEL, SAID LARD-AIR MIXTURE BEING REDUCED IN TEMPERATURE WITHIN THE CHILLING VESSEL TO SUCH AN EXTEND THAT IT LOSES ITS LIQUIDITY AND IS REDUCED TO THE VISCOSITY OF A FREE-FLOWING PASTE, PASSING THE CHILLED LARD-AIR MIXTURE THROUGH A FIRST AGITATOR AT HIGH PRESSURE AND BEATING IN THE ENTRAINED AIR TO PRODUCE A SUBSTANTIALLY SMOOTH LARD-AIR DISPERSION, FORMING A HOT AQEOUS DISPERSION OF ANIMAL PHOSPHATIDES, COLLOIDALIZING THE AQUEOUS DISPERSION TO FORM A SMOOTH AQUEOUS EMULSION, KEEPING THE EMULSION WARM, PUMPING THE WARM EMULSION TO FORM A FLOWING STREAM THE VOLUMETRIC RATE-OF-FLOW OF WHICH IS PRECISELY PROPORTIONATE, AT SELECTED RATIO, TO THE VOLUMETRIC RATE-OF-FLOW OF THE LARDAIR MIXTURE INTO THE COOLING WORM, INJECTING THE PROPORTIONED FLOW OF THE WARM EMULSION AT HIGH PRESSURE INTO THE FLOURING STREAM OF THE LARD-AIR DISPERSION, TRANSMITTING THE EMULSION-DISPERSION MIXTURE THROUGH AN EXTRUSION CHAMBER IN WHICH THE STREAM IS RENDERED TURBULENT, AND PASSING THE EMULSION-DISPERSION MIXTURE THROUGH A SECOND AGITATOR TO PRODUCE A SMOOTHLY EMULSIFIED SHORTENING.
