Method of treating dry aspartame and aspartame recovered thereby

摘要

The present invention relates to a method for treating dry aspartame, wherein in the first separation step, more than 5% by weight of aspartame has a particle size smaller than 20 μm and more than 10% by weight of aspartame has a particle size larger than 400 μm. The particles obtained smaller than 50 μm were removed from the aspartame having an air stream, and after the screening step using a screen for separating the product obtained in the first step at a value of 150 to 250 μm in the second separation step, The smaller particle fraction thus obtained is recovered as the first product, and the smaller particle fraction thus obtained is optionally subjected to a further separation step using a screen to recover the larger particle fraction as the second product or to separate at a value of 400 to 1000 μm. It is characterized by a recovery box.;Aspartame has a particle size distribution of 97% of particles larger than 20 μm and 97% of particles smaller than 250 μm, which shows particularly good properties in terms of processability and dissolution rate.
