Eliminating Cross-Connections Between Raw and Pasteurized Products in Dairy Plants
1Food and Drug Administration, Center for Food Safety and Applied Nutrition, Division of Food Chemistry and Technology, Food Engineering Branch, Cincinnati, Ohio 45226.
Abstract:
A method was developed to identify cross-connections between raw and pasteurized products in dairy plants. A flow diagram of the dairy plant is used to identify post-pasteurization pumps, storage tanks, fillers or other post-pasteurization processing equipment. An envelope is drawn on the flow diagram around all post-pasteurization equipment. Only the few pipelines that penetrate the envelope have the potential of a cross-connection. Each pipeline is traced to its origin to determine if it is a cross-connection.

01:25Cross Product
The magnitude of the cross product is obtained by multiplying the magnitude of both the vectors and the sine of the angle between them. This means that a larger angle between the vectors will lead to a greater magnitude of the cross product.
