Objectives Of Heat Transfer:
Heat is a form of energy that can be used in many forms to perform industry scale operations.
Electricity and steam are two main sources of the energy that are used in industries.
Knowledge of heat transfer is essential in order to avoid heat loss.
Knowledge of heat transfer helps in designing efficient and economical plants.
Applications of Heat Transfer:
Heat transfer has numerous applications in the industry, the notable applications related to the pharmaceutical engineering are as follows,
Crystallization:
It is an important process employed for the purification of pharmaceutical products.
Application of heat to a saturated solution of a substance brings supersaturation causing the crystallization of the substance.
Distillation:
In this process the liquid mixture is boiled and the mixture components are separated in the form of vapours and collected separately.
For boiling the mixture, heat is used.
Drying:
It simply means removal of moisture or a solvent, which can be achieved by application of heat.
Evaporation:
In this pharmaceutical process heat is applied to a liquid to convert it into vapors which can be removed.
This process is used for concentrating the preparations particularly vegetable extracts
Sterilization.
It is the complete removal of microbes from any given object or substance.
Dry as well as wet forms of heat are employed to achieve sterilization of pharmaceuticals.
