9 Claims

1. A method for crystallizing aqueous carbohydrate-containing substances, characterized in that it comprises:

i) remove foreign matter from the aqueous substance containing carbohydrates;

ii) mix the aqueous substance containing carbohydrates with at least a water absorbent medium until a mixture of semi-solid particles with a size of 3 mm on average is obtained;

iii) distribute the above mixture in a 1 to 5 mm thick layer on a container;

iv) heat the layer of the mixture from the previous step in a microwave oven at a power of 0.585 kWh per 1 kg of mixture for 30 to 180 sec;

v) cool the mixture layer to a temperature of −80 to 40° C. for 2 to 480 s;

vi) repeat steps iv) and v) consecutively until the mixture layer reaches a moisture content of 2 to 4% and thus crystallization;

vii) pulverize the crystallized layer-mixture until crystals with an average particle size of 2 mm are obtained;

viii) remove the water absorbent medium from the crystals of an aqueous substance containing carbohydrates, by vibration and sieving with mesh number 80, until the absorbent medium is separated; and

ix) to recover the crystals from aqueous substance containing carbohydrates, obtained.
