Continuous crystallizer Vacuum continuous cooling crystallization System 2021 Applications:
Vacuum continuous cooling crystallization system is widely used in chemical, pharmaceutical, pesticide and other industries such as oxalic acid, succinic acid, sodium citrate, manganese sulfate heptahydrate and other biochemical enterprises have special requirements for crystallization temperature, particle and grain distribution.
The traditional crystallization industry generally adopts intermittent crystallization process. As an important part of chemical operation unit, the size of crystal particles directly affects the quality, purity and final sales price of the products. The vacuum continuous cooling crystallization technology developed by our company is the leader of the industry technology. It can realize high-tech problems such as adjustable crystallinity, which makes the product granularity more uniform, purity higher, and automation higher. In addition to reducing investment cost and production operation cost, the products with stable quality and high quality have stronger market competitiveness..
Working Principle:
In vacuum state, the hot saturated solution is cooled and crystallized by adiabatic vacuum cooling. When the hot solution enters the crystallizer and reaches the liquid level of the separation chamber, the solution will flash and evaporate. Part of the solvent will absorb heat, and the solution will cool down to produce supersaturation and crystallize. In essence, the solute is separated from the solution in the form of crystal by lowering the temperature( It is especially suitable for substances whose solubility increases with temperature.
The Main Features:
Good hydrodynamics
The high efficiency internal circulation is realized without secondary nucleation
There is little scaling on the inner wall
Used in pharmaceutical plants to meet GMP requirements
The slurry supersaturation is uniform, the particle distribution is good, and the high efficiency is achieved
Low energy consumption
Continuous production operation can be realized
It can be used for cooling crystallization or vacuum evaporation cooling crystallization
The System Composition:
The system is mainly composed of raw material tank, condenser, crystallizer, vacuum system, axial flow pump, material pump, automatic control system, platform and all pipeline valves. Steve Sales Manager
