Claim 1
Independent Claim
143 words
A METHOD OF COOLING, MIXING AND HOMOGENIZING A MIXTURE OF IMMISCIBLE MATERIALS IN A LIQUID CARRIER WHICH COMPRISES PASSING SAID MIXTURE INTO AN ANNULAR SPACE DEFINED BY AN OUTER TUBULAR HEAT EXCHANGE SURFACE AND AN INNER SHAFT DISPOSED WITHIN SAID TUBULAR HEAT EXCHANGE SURFACE WHEREINB SAID OUTER SURFACE IS COOLED BY MEANS OF A LOW TEMPERATURE MATERIAL, APPLYING A ROTATIONAL COMPONENT OF MOVEMENT TO SAID MATERIAL WITHIN SAID TUBULAR HEAT ECHANGER, AND APPLYING A SERIES OF INTERMITTENT PRESSURE PULSATIONS TO SAID MATERIAL WITHIN THE TUBULAR HEAT EXCHANGER, WHEREBY THE MATERIAL IS MOVED IN A SLOW SPIRAL MOTIONB HA VING IMPOSED THEREON A SERIES OF INTERMITTENT LONGITUDINAL BACKWARD AND FORWARD MOTIONS, PASSING SAID MATERIAL LONGITUDINALLY THROUGH THE CYLINDRICAL HEAT EXCHANGE UNIT WHILE IT IS SUBJECT TO ROTATIONAL AND KNEADING ACTION THEREBY TO COOL AND HOMOGENIZE THE PRODUCT INTO A STABLE, SMOOTH, UNIFORM, HOMOGENOUS MATERIAL.
