Abstract

Abstract Free-flowing particles of glucose, fructose or mixtures thereof are produced by kneading an anhydrous powder of the sugar with a 40-90% by weight solution of said sugar to give a kneaded mixture having a moisture content of less than 7%, shaping the resultant mixture into the form of granules, pellets or the like and drying at a temperature below 70* C.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 112 words
A METHOD FOR PREPARING ANHYDROUS, FREE-FLOWING SOLID PARTICLES OF A SUGAR SELECTED FROM THE GROUP CONSISING OF GLUCOSE, FRUCTOSE AND ADMIXTURES THEREOF, WHICH COMPRISES: A. KNEADING AN ANHYDROUS POWDER OF SAID SUGAR WITH A 40-90% BY WEIGHT SOLUTION OF SAID SUGAR IN AN AMOUNT OF 5-65% BY WEIGHT OF SAID POWDER WITHIN THE AREA SHOWN BETWEEN POINTS A, B, C AND D OF THE ATTACHED DRAWING WITHOUT SUBJECTING SAID SOLUTION TO A CRYSTALLIZATION STEP TO FORM A KNEADED MIXTURE HAVING A MOISTURE CONTENT OF LESS THAN 7% BY WEIGHT; B. SHAPING SAID KNEADED MIXTURE INTO PARTICLES; AND C. DRYING THE SHAPED PARTICLES AT A TEMPERATURE LOWER THAN 70*C. TO FORM ANHYDROUS PARTICLES.
Claim 2
Independent Claim 112 words
A METHOD FOR PREPARING ANHYDROUS, FREE-FLOWING SOLID PARTICLES OF A SUGAR SELECTED FROM THE GROUP CONSISING OF GLUCOSE, FRUCTOSE AND ADMIXTURES THEREOF, WHICH COMPRISES: A. KNEADING AN ANHYDROUS POWDER OF SAID SUGAR WITH A 40-90% BY WEIGHT SOLUTION OF SAID SUGAR IN AN AMOUNT OF 5-65% BY WEIGHT OF SAID POWDER WITHIN THE AREA SHOWN BETWEEN POINTS A, B, C AND D OF THE ATTACHED DRAWING WITHOUT SUBJECTING SAID SOLUTION TO A CRYSTALLIZATION STEP TO FORM A KNEADED MIXTURE HAVING A MOISTURE CONTENT OF LESS THAN 7% BY WEIGHT; B. SHAPING SAID KNEADED MIXTURE INTO PARTICLES; AND C. DRYING THE SHAPED PARTICLES AT A TEMPERATURE LOWER THAN 70*C. TO FORM ANHYDROUS PARTICLES.
Claim 3
Dependent Claim 15 words
