Course guide on
Food Plant Design and Pilot Demonstration(FST 409)
University of Agriculture, AbeokutaDepartment of Food Science and Technology
Synopsis Concept of a food plant Plant design concepts
Definitions Process design Optimal design principles Sanitary design
General appreciation of the food industry and various plant facility need
Design principles Feasibility study Site selection Plant economics and profitability
Concept of a Food Plant
Food plant as physical entity Conversion processes in a food plant Energy consumption and cost Waste generation Human expertise need Life cycle of a plant
Plant design concepts
Design as an idea generation exercise Fitness to a purpose Enormity of task depends on the intended scale
of operation of the plant
Food Plant design as a multidisciplinary project Coordinated by a Food Engineer/Food
Technologist Team may involve all or some of the following:
Civil, Engineer, Mechanical Engineer, Electrical Engineer, Accountants, Architects, Quantity Surveyor, Economists, etc.
Definitions
Food process Process simulation Process optimization Process instrumentation and control Food plant sanitation
Stages in plant design
Inception Preliminary evaluation of economics and
market Development of data necessary for final design Final economic evaluation Detailed engineering design Procurement Erection Startup and trial runs Production
The Food Industry
The producers The processors The marketers The consumers
