Attributes of the resulting crystal depend largely on factors such as temperature, air pressure, and in the case of liquid crystals, time of fluid evaporation.Д¬rystallization occurs in two major steps.

Some of the ways by which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas.

CrystallizationД¬rystallization is the (natural or artificial) process by which a solid forms, where the atoms or molecules are highly organized into a structure known as a crystal. For other uses, see Crystallization (disambiguation). 'Crystallizing' and 'Crystallized' redirect here.

ChemicalsпїЅcommercial grade material as per choice.

To determine the crystal yield and the efficiency of crystallizer.

To study the performance of a Swanson Walker Crystallizer.

Necessary instrumentation is done for temp measurement Experiment : Arrangement for Cooling water circulation and flow measurement in jacket is made by using storage type water tank, a pump and a rotameter. The crystals sediments at the bottom of the trough, and can be washed out at the end of process. This hot saturated solution is fed at one end of the crystallizer and flows slowly towards the other end while being cooled and is allowed to flow back in hot feed tank making the process continuous. The saturated solution is prepared in a tank fitted with heater and a stirrer. A ribbon mixer is provided in crystallizer trough, which rotates at low rpm for agitation of saturated solution. The setup consists of a top open jacketed round bottom trough. The mechanical design of the crystallizer has a significant influence on the nucleation rate due to contact nucleation.
