   Reaction Crystallizer
Position:Home > Reaction Crystallizer >

Reaction crystallization refers to the chemical reaction between a gas and a liquid or liquid or liquid to produce insoluble or insoluble solid matter. Reactive crystallization can make some easily precipitated substances separate from other compounds, so as to achieve the purpose of purification. The reaction crystallization process is characterized by high selectivity and is often used in the separation and purification of products.

普通結晶罐自動化程度低,兩相或多相物料混合,為了達到好的混合效果,攪拌強烈,容易產生大量細晶,當細晶小于1μm 時,細晶會有團聚現象,即范得華力會起作用。因此產品粒度分布過寬,粘度變大,洗滌量增加,離心后晶間包裹的殘液量相對增大,導致產品純度低,另外操作靠經驗和簡單的指標控制,不同班次工人操作有差異??寇囬g管理難解決問題,導致產品批間差異大,粒度分布不均勻,產品質量不穩定;從綜合成本考慮,間歇操作繁瑣,動力消耗高,不適合批量產品的生產。
Several factors affecting reactive crystallization: degree of saturation, temperature, mixing uniformity, agitation strength, and material purity. The ordinary crystallization tank is low in automation, and when the two phase or multiphase materials are mixed, In order to achieve good mixing effect, the stirring process can be strong and easily producing a lot of fine grains. When the fine grain is less than 1 m, the fine grain will reunion, the Van der Waals force will come into effect. Therefore, when the product size distribution is too wide, the viscosity becomes larger, the washing capacity increases, and the residual liquid content between the crystals increases relatively after centrifugation, the low purity of the product will be caused. In addition, the operation is controlled by experience and simple indicators, and there are differences in the operation of workers in different shifts. The difficulty to solve problems by workshop management results in large differences among the products, uneven distribution of grain size, and unstable quality of products. Considering the comprehensive cost, the intermittent operation is tedious, the power consumption is high, and it is not suitable for the production of mass products.
The reaction crystallization equipment can completely solve the above problems, and the product quality has reached the foreign advanced standards.  The reaction crystallization is a complex process of heat and mass transfer. In different physical and chemical environments, the control steps of the crystallization process may change and reflect different behaviors. Especially for the pharmaceutical crystallization products. They have strict requirements on the crystal type, and also on the particle size distribution of the products, which directly affects the quality of drugs.
ND Crystallizer: easy to control the internal temperature, pH value of solution; simple structure, low energy consumption, uniform distribution of crystals; can produce high-purity large crystal grains based on indications; easy to filter; a great improvement to product quality.
The inner wall and draft tubes of ND Crystallizers are polished to reduce wall scars.
equipped with crystal elimination device; The upper micro crystal enters the fine crystal eliminator and then becomes supersaturated solution, continues to crystallize.
The lower part of the crystallizer is provided with a panning leg, which is beneficial to the extraction of the larger crystals.
If necessary, the crystal seed feeder can be added to further improve the particle size distribution
we can adjust the reaction crystallization temperature according to the optimum reaction rate
Operating voltage: 380V; working time: 24h/d
Automatic control part: according to the design requirements of the automatic control part, the system can achieve the following goals:
The technical parameters of each controller ensure the requirements of the process, and can automatically monitor and control the crystal temperature and other indicators. The pump adopts frequency conversion control, and the feed and discharge operations can be automatically controlled;
The field executing organization has the system information uploading interface, and can access the DCS system.
