A Pasteurization System of Prototype In-Line-Stirred Yoghurt Machine, Designed and Constructed for Use by SMEs
Type Of : Academic Manuscript
Type : Science
A prototype for an in-line stirred yoghurt production machine was designed and constructed for use in an SME dairy plant. The prototype consisted of a shell and tube heat exchanger, and a forced draft burner for heating milk to 72- 82 o C with a milk flow rate of 884 ml/min. During the pasteurization process, this holding temperature was maintained for a period of 67 seconds. Thereafter, the pasteurized milk was cooled to 42-45 o C through the use of cold water, before being transferred to an incubation tank. Results showed that the prototype was consistently able to maintain the pasteurized temperature, whilst still keeping a normal milk taste and smell, the phosphatase enzyme was not found.
