Embodiment 1

[0035] In this embodiment, sucrose is used as the solute, water is used as the solvent, and methanol is used as the eluent.

[0036] The results of particle size analysis of the seeds induced by ultrasound and the seeds produced by grinding are as follows: image 3 and 4 As shown, it can be seen from the figure that the main particle size and particle size distribution range of the sucrose seed crystals induced by ultrasound are far superior to those produced by grinding, so it is easier to produce crystals with uniform particle size distribution. Seed crystals are easier to disperse in the crystallization mother liquor container. Therefore, when the volume of the crystallization module can ensure uniform mixing, there is no problem of dispersion of the ultrasonically induced seeds.

Embodiment 2

[0038] Two sets of ultrasonic crystallizers are installed on the 100-liter crystallization mother liquor container, each group contains three 60W ultrasonic generators, and the generated ultrasonic waves are focused on the circulation area of ​​the crystallization mother liquor. In the crystallization mother liquid container, water is used as solvent and methanol is used as eluent to produce sucrose crystals. Dissolve 2.6 kg of sucrose in 15 kg of water. Add 80 kg of methanol at a uniform speed to carry out intermittent elution and crystallization.

[0039] When the ultrasonic nucleation inducer is not turned on, the crystal nuclei are precipitated when 19 kg of methanol is added. Stop feeding methanol for half an hour and resume feeding. After adding all 80 kg of methanol, the crystallization system continues to stir for 40 minutes, and filter , drain the mother liquor, wash the crystals with methanol at room temperature, and conduct particle size analysis. The particle size...

Abstract

The invention discloses a crystallizer capable of controlling crystallization and nucleation process through ultrasonic wave. The crystallizer comprises a crystallization mother liquid container (3) and at least one group of nucleation inducers (6), wherein each group comprises a plurality of nucleation inducers (6); each nucleation inducer (6) comprises an ultrasonic transmitting sheet (1) and an energy guide head (2); the energy guide head (2) is fixed with the outer wall of the crystallization mother liquid container (3) in a fitting mode. The quality of crystal products is effectively improved. The ultrasonic wave enables the nucleation process of the crystals occurs under the condition of low supersaturation degree or enables an object system difficult to nucleate to realize nucleation, so that the control of the crystallization process is controlled, and the granularity, the granularity distribution and the crystal form of the products are improved.

Description

technical field [0001] The invention belongs to the field of crystallization equipment, in particular to a crystallizer for controlling the crystallization nucleation process through ultrasonic waves. Background technique [0002] Modern industrial crystallization technology and equipment are the common core technology for the preparation of high-end biomedical products, the core technology for finishing processing with green and intelligent features, and the core technology for realizing the upgrading of biomedicine from low-end crude products to high-end functional products. The overall improvement of the competitiveness of the biomedical industry is a key common core technology that has a driving and overall impact. Strengthening research and development in this field has become a strategic commanding height that must be seized. [0003] Crystal nuclei are tiny crystal particles newly produced in a supersaturated solution and are the essential core of the crystal growth ...
