scope:

These 3-A Accepted Practices shall pertain to high-temperature short-time (HTST) and higher-heat shorter-time (HHST) pasteurization equipment, appurtenances, and controls used in a complete pasteurization system for milk and milk products. In addition to pasteurization, such systems may include flavor control, vacuum treatment, homogenization, clarification, separation, or other processes, which if included, are to be installed so that they do not influence required time, temperature, flow and pressure relationships.

In order to conform to these 3-A Accepted Practices, HTST or HHST pasteurizer systems shall conform to the following design, material, fabrication and installation criteria.¹

An Appendix is also included covering Application to Install, Operation, Determination of Holding time and Pressure Relationships, Stainless Steel Materials, Product Contact Surface Finish and a list of 3-A Sanitary Standards and Accepted Practices referred to in the text. (NOTE: Numbered end notes and references are assembled in Appendix, Section R, on pages ___ to ___.)
