This free book can be obtained at the website of the New Zealand Institute of Food Science and Technology.The book is published in flash but gives assistance in how to print chapters and how to download to use offline.

The book is a detailed engineering approach to the processes that make up food manufacturing businesses. It includes detailed calculations, diagrams, charts and flowsheets.
While the book covers detailed information that is probably not usable by everyone, there are also simple general descriptions that would be useful to anyone approaching new plant and processes.
