HEAT TRANSFER IN THE FOOD PROCESSING INDUSTRY

One of the common engineering disciplines used in food processing is heat transfer.

It plays a pivotal role in enhancing the safety, nutritional and sensory aspects of the product. There are multiple sub-processes like sterilization, freezing, preservation, and freezing in the food processing industry. All of which rely on delivering the right and consistent quality to its customers.

One of the challenges of heat transfer in the food and beverage industry is steady and unsteady heat transfer taking place in different sub-processes. As well as heating raw materials with irregular shapes, physical properties which vary during the process cycle, non-uniform and sometimes variable consistency.

Because of the non-Newtonian nature of the foods, their thermal behavior has always remained a challenge to model and a better engineering understanding to solve the unsteady heat transfer differential equations by analytical solution with simplifying assumptions is required.
