Overview of Heat Exchangers in the Food Processing Industry

This lecture by Pawan S. Takhar from Texas Tech University provides a comprehensive overview of heat exchangers utilized in food processing. It covers various types such as concentric tubes, shell-and-tube, and plate types, including their applications in pasteurization, heating, and concentration processes. Key concepts such as counter-current and co-current flow, overall heat transfer coefficients, and specific heat calculations are discussed, along with practical implementations in processes like juice concentration and ice making.
