The evolution of this book is a consequence of two decades of teaching this subject to B. Pharmacy students. The primary objective of this book is to present some easy practicals to demonstrate the concepts of pharmaceutical unit operations in simple language. The book has been enriched with detailed write-ups as demonstration practicals on various machines for their easy understanding. A total of 200 multiple choice questions on pharmaceutical engineering make this book a unique and must have text. It prepares the readers for various competitive examinations and end semester examination
