Book Description

Existing maintenance engineering techniques pursue equipment reliability with a focus on minimal costs, but in the food industry, food safety is the most critical issue. This book identifies how to ensure food product safety through maintenance engineering in a way that produces added value and generates real profits for your organization.

Integrating food safety techniques with reliability and maintenance engineering techniques, Designing Food Safety and Equipment Reliability Through Maintenance Engineering details a maintenance design process that captures all conceivable critical factors in food manufacturing lines. While maintenance engineering normally starts with equipment reliability, this book starts with product safety to identify equipment criticalities and maintenance solutions.

The text examines the problems currently facing the food industry and introduces powerful solutions to help food producers and consultants manage both food safety and manufacturing effectiveness. It presents an innovative tool for weighing food, human, and equipment criticalities and also describes how to maximize maintenance design outcome through the empowerment of equipment operators and their close cooperation with maintenance and quality specialists.

Detailing how to design reliable task lists, the book includes case studies that illustrate the problems that low equipment reliability can create for your customers and your company’s image. It outlines key performance indicators that can help producers and suppliers easily identify quality, availability, and productivity gaps. It also highlights critical factors that can help you avoid process bottlenecks.
