Heat Enhancement of Plate Heat Exchanger Working Efficiency by using Turbulators in Dairy Milk Pasteurization System

The heat exchangers are generally used to transfer heat from one medium to another medium. The heat exchanger are generally used for space heating, refrigeration, air conditioning, power plants, chemical plants, petrochemical plants, petroleum refineries, natural gas processing, and sewage treatment. A Plate Heat Exchanger is a type of heat exchanger that uses metal plates to transfer heat between two fluids. An experimental was conducted in Bhopal Sahakari Dugdh Sangh (BSDS) on Plate Heat Exchanger. Plate Heat Exchangers are used to pasteurize milk in BSDS, in which the hot water is used to transfer heat towards milk by which milk is pasteurized. The temperature of pasteurization milk is set on 78°C in Bhopal Sahakari Dugdh Sangh plant for milk properties, when the temperature of pasteurized milk become below 78°C the milk come in raw milk tank to again pasteurize. By which we got the working plate heat exchanger efficiency of Bhopal Sahakari Dugdh Sangh is 55.05%. We enhance the working plate heat exchanger efficiency of Bhopal Sahakari Dugdh Sangh by placing different Turbulators (Twist tape turbulator, Brock turbulator and Wire turbulator). In inlet hot water pipe. We got the working efficiency of Plate Heat Exchanger in these Turbulators are 71.01%, 62.64% and 63.31. The experiments proposed for counter flow models of the fluids. After modification by Turbulators in Plate Heat exchanger set up we got that Twist Turbulators is better Turbulators than other turbulator.
