[0002] In many industries such as chemical industry, pharmacy and food, concentration crystallization is a very common and important process link, which aims to separate specific solute from solution or mixture to obtain high-purity crystalline product. Traditional concentration crystallization process often uses relatively simple reaction kettle equipment. Such equipment usually only has basic stirring function, aiming to mix materials in the reaction kettle uniformly to promote heat transfer and chemical reaction.
[0003] However, with the continuous improvement of product quality requirements in various industries, the traditional reaction kettle has many limitations. In the material processing process, due to the lack of effective material pretreatment mechanism, material caking phenomenon is easy to occur. These caked materials not only cause local concentration to be too high, thus causing uneven crystallization, resulting in uneven quality of the final crystalline product, different particle sizes and reduced purity, which seriously affects the performance and application value of the product. Moreover, the traditional reaction kettle has obvious shortcomings in material screening, which cannot effectively separate materials of different particle sizes in the reaction process, resulting in large particle materials that do not meet the crystallization requirements continuously participating in the reaction, which reduces the crystallization efficiency and increases energy consumption and production cost.
