Project overview

There are a lot of dissolution, reaction, crystallization, concentration, adsorption, purification and other processes in the production process of API. Through stirring, each group can be dispersed and dissolved, and its flow can be fully contacted with each other, strengthening the material transfer, increasing the reaction speed and transfer rate, and the effect of stirring also directly affects the quality of concentrated crystallization. The efficiency of mixing directly affects the production cost of the raw material, so the selection calculation is very important.

Description of materials and working conditions

1, preparation of mixture: two or more kinds of liquid, through stirring to achieve a uniform mixture of mass and heat transfer.

2, preparation of suspension or emulsion: the two kinds of non-disintegrating liquid fully emulsified, increase the interphase contact area, through dispersion to achieve a state of uniform mixing of two-phase liquid.

3, preparation of solid-liquid suspension: the solid and liquid mixing, so as to achieve the effect of uniform suspension of solid particles in the liquid.

4, concentrated crystallization: through the evaporation of the solvent, the material in the tank will crystallize when it reaches a certain concentration, and the size of the shear force generated by the stirring paddle and the speed of the liquid flow determine the crystallization result.

5, accelerate the reaction: strengthen the heat transfer effect, forced convection, to achieve a variety of materials evenly mixed.

The newly launched Re3 magnetic suspension stirring series can meet the fast mixing of low viscosity liquids, has the characteristics of large torque and small volume, has the function of zero gravity dry operation, simple installation, stable and reliable.

The magnetic stirring high-torque semi-submersible design on the Re7 can meet the requirements of aseptic mixing, and various mixing paddles can be configured according to the process.

Re16 magnetic anchor paddle stirring, large torque semi-submersible design, can meet the requirements of concentrated crystallization, can also choose the mechanical seal structure mixing, can also meet the working conditions.
