Study Notes
Agricultural and Food Processing Plant Design
- Plant design encompasses the entire manufacturing facility, considering technical and economic factors, existing and potential market conditions throughout all stages.
- Plant design stages include identifying the product, feasibility analysis, economic evaluation, report preparation, material procurement, plant and machinery construction, and installation/commissioning.
- Plant design specifications define equipment, performance requirements, material flows (flowcharts and layouts), placement of equipment, storage spaces, office/shipping facilities, and site plans/drawings. Utility and waste treatment requirements, and site selection rationale are also crucial.
Differences in Food and Non-Food Processing Plants
- Food processing plants handle more variable and less well-known properties of foods and biological materials compared to non-food chemical processes.
- Food products are often living organisms, or biochemically active, with varying sensory characteristics and limited shelf life, sensitive to temperature, pH, water activity, maturity, and microbial contamination.
- Food safety and sterility requirements are very high in food processing. Food raw material availability is often seasonal, impacting plant design.
Plant Design Considerations
- Deterioration minimization is crucial in food processing, accomplished through provisions for refrigerated storage, controlled environments, quality assurance, and surge vessels to help in case of equipment breakdown.
- Contamination prevention is vital and involves smooth, easily cleanable surfaces, separate areas for raw materials, production, and finished goods, and rigorous sanitation standards.
- Seasonal production demands flexible plant sizing to accommodate peak seasonal fluctuations in raw materials without excessive delays or waste. Crop and animal growth modeling aids scheduling.
Flow Charts in Process Design
- Flow charts represent a visual depiction of process operations step-by-step using standardized symbols, including ovals (start/end), rectangles (steps), diamonds (decisions), parallelograms (input/output), and arrows (direction).
- Flowcharts are a common process analysis tool used to visualize, standardize, and improve existing or new processes.
- Flowcharts can be high-level (overviewing major steps) or detailed (showing numerous steps) depending on the level of detail necessary for a particular process evaluation.
