Crystallization is a method generally used for purifying substances, so that the constituents of a solution can be separated. A solution must reach a supersaturated condition in order to crystallize its solute. To saturate a solution, a product, called solute, is dissolved in it to such a degree that the solution is unable to dissolve more solute.

There are several methods used to obtain a supersaturated solution:
By evaporation.
By cooling.
By adding aggregates.

The Crystallization Unit (QUCB), developed by EDIBON, is a cooling crystallization unit. Therefore, it is suitable to perform crystallization
experiments with those constituents whose solubility changes according to the temperature. One of the main advantages of the cooling method is its low energy costs. A crystallizer is a reactor where a crystallization process takes place. A crystallizer can be batch or continuous operated.

The QUCB is an unit for the study of the cooling crystallization process. EDIBON has developed this unit to study the crystallization reaction of
those constituents whose solubility changes with the temperature. This unit is devised to perform batch crystallization, that is to say, the crystallizer is filled once with the solute and solvent until the supersaturated solution is obtained and crystals are obtained from that solution. It is a batch (or discontinuous) process because the crystallizer must be filled again to carry out a new experiment.

QUCB unit includes a crystallizer, which is basically a jacketed chemical reactor. There is a bath outside the crystallizer, through which the reaction temperature is controlled. The solution is stirred by a stirrer located at the upper side of the crystallizer. Besides, there is a temperature sensor at the upper side of the crystallizer to know the temperature of the solution inside at any moment.

The unit also includes a conductivity sensor to know the conductivity of the solution when it is required. To obtain the supersaturated solution, it must be heated so that it is able to dissolve a higher concentration of solute at high temperatures. There is a thermostatic bath to supply water to the crystallizer's jacket. Its control is done by means of a potentiometer.

Once a supersaturated solution at a high temperature is obtained, the crystallization stage starts. For that purpose introduce cold or room temperature water. The unit includes a pressure regulation valve kept to the minimum pressure. A sample of the collected product is analyzed with the filters set provided with the unit. The size of generated crystals can be obtained thus. It has an optional accessory: Continuous Feed Unit (QUCB/C) to turn this unit into a continuous crystallization unit.
