Introduction
The oscillator of a clapper gate type crystallizer may be described as a combination of a force generator, an elastic member, a mass, and a damping device. The force generator may be spring loaded or otherwise linked and can provide an oscillating force to the system. The elastic member, typically in the form of a plate, is attached to the force generator and serves to store energy in the system through its deformation which is forced upon it by the oscillations of the force generator. The mass may also be attached to the elastic member and serves to further store energy in the system. The damping device may be any type of mechanical or hydraulic damping device which serve to dissipate energy from the system.
The operational principle of clapper gate type crystallizers is that when the force generator is set in motion, the elastic member will deform and thus store energy in the system. As the system oscillates, part of the energy stored in the system is released, while the other part is absorbed by the damping device. This process of energy being stored and then released is called an oscillation.
In practical terms, a clapper gate type crystallizer vibrates at a certain frequency which depends on the properties of the force generator, the elastic member, the mass, and the damping device. The frequency of oscillation is also affected by the type of material used in the force generator and the elastic member. The period of oscillation is also affected by the type of material used in the damping device and the mass of the system.
The use of clapper gate type crystallizers is mainly used for the creation of crystalline materials such as sugar, salt and various other minerals. The oscillations created by the force generator and elastic member are used to shape and orient the crystalline material into its desired form. As the oscillation period of the clapper gate type crystallizer vibrates at its specified frequency, the crystalline material is forced to orient itself in certain manners, thus creating a uniform crystal structure.
The use of clapper gate type crystallizers has also become widespread in the manufacture of pharmaceuticals as it allows for the production of highly homogenous crystalline structures with extremely small dimension. This type of crystalline structure is highly sought after in the pharmaceutical industry due to its better bioavailability.
Conclusion
In summary, a clapper gate type crystallizer is a specialized device used for the production of homogenous crystalline materials. The device works by forcing its force generator to oscillate at predetermined frequency, thus forcing the material to orient itself in certain ways. The use of clapper gate type crystallizers is mainly for the production of pharmaceuticals, as the homogenous crystalline structures produced have better bioavailability.
