A PROCESS FOR THE CRYSTALLIZATION OF NON-SUCROSE SUBSTANCES
摘要
The invention relates to a process for the crystallization of substances having a narrow metastable supersaturation zone. In the process the saturation of a solution is gradually increased and the solution is seeded for the crystallization. The seeding is performed at a seeding point which is selected in response to a signal received from said process indicating imminent or initial spontaneous nucleation. The process provides a good crystal yield and a crystalline product having a uniform crystal structure and a narrow crystal size distribution.
