Abstract

The invention discloses ultrasonic crystallizing equipment used in natural product or chemical agent crystallization and purification. The equipment comprises a crystallization chamber, an ultrasonic transducer, a temperature probe, a turbidity probe, a stirring device and a master controlling system. The crystallization chamber has a sandwich structure. An inlet is arranged on the upper part of the crystallization chamber, and an outlet is arranged on the lower end of the crystallization chamber. The ultrasonic transducer is arranged on the outer wall of a circulation pipeline. The temperature probe and the turbidity probe are arranged in the crystallization chamber, and are used for transmitting electrical signals to the master controlling system. With ultrasound, nucleation is reinforced and excited, and crystal growth speed is improved, such that crystallization period is shortened, and production efficiency is improved. The particle sizes of the crystals are uniformly distributed, such that the product quality is improved. The equipment is time-saving, and is advantaged in high efficiency and high product quality. The entire production process is controllable, and the equipment can be used in industrialized productions.

Description

technical field [0001] The invention relates to a device for crystallization and purification of natural products or chemical drugs, in particular to an ultrasonic crystallization device for crystallization and purification of natural products or chemical drugs. Background technique [0002] Ultrasound refers to sound waves with a frequency above 20KHz. It cannot cause human hearing. It is a propagation process of mechanical vibration in a medium, and has the characteristics of beamforming, orientation, reflection, and transmission. As a form of physical energy, ultrasound has been widely used in natural product extraction, chemistry and chemical engineering, environmental protection, food industry, bioengineering, etc. [0003] The solution crystallization process is a process in which a substance changes from a liquid state to a crystalline state, and it goes through two steps: crystal nucleation and crystal growth. Crystallization nucleation is to generate a certain numb...
