| titleOfInvention | Method for preparing crystalline d-psicose |
| abstract | The present application relates to a method for preparing crystalline D-psicose. In the present application, crystalline D-psicose is prepared by means of combining an evaporative crystallization method and a cooling crystallization method, so that the preparation process is simple, the operation is easy, and the crystallization period is short. In the present application, a seed crystal is added when the solid content is relatively low (70-75%) in an evaporative crystallization process, so that the crystallization process is facilitated, the growth speed of the crystal in each direction is more uniform, the whole crystallization period can be shortened, and the energy consumption is reduced; and after the evaporative crystallization is finished, crystal regulation is carried out, so that the crystal size tends to be equalized, the crystal surface grows to be smooth, and the crystal form is perfected. Cooling crystallization is carried out after the crystal regulation, and the cooling frequency of specific cooling intervals is designed in the cooling process according to the metastable region curve of D-psicose. After crystallization by means of the preparation method of the present application is finished, the obtained crystal has a high yield, a narrow crystal size distribution, a smooth crystal surface, a mirror-like surface, good reflectivity and a regular crystal form. |
