UNIT-V FMM.HYDRAULIC TURBINE - Construction and working
Process engineering for appropriate technology development
1. Career & Capacity Building
Process Engineering for Appropriate
Technology
With Engr. Akachidike Kanu
Webinar Lecture presented to:
FUTY (Fed Univ ofTechYola Nigeria) Alumni Group
2. Industrialization
• Industrialization: the development of
industries in a country or region on a
wide scale – Oxford Dictionary
• Industry: large-scale business activity
or a type of productive manufacture or
trade
Process enablers
1. Industrialize an agricultural region
(policy)
2. Produce/supply processed agro
products on a large scale (business)
3. Study, design and operate fertilizer
plant (engineer)
3. Industrial Process Engineering
• Process Engineering: processes and equipment for
turning raw materials (feed) into product. Essential
part of many industries – manufacturing, utilities,
energy, mining, supply chain, healthcare, etc.
• Chemical Engineering: …emphasis on change of state
and composition of matter in a controlled process
• Manufacturing engineering: …emphasis on
machining/ assembling (screws, bolts, welds, glues,
rivets) individual pieces into a distinct product
• Industrial Engineering: …optimizing integrated
systems of people, money, knowledge, information,
equipment, energy and materials.

6. Potent industries
• Grain and root crop processing (Garri, yam,
plantain, processing)
• Extracts and concentrates (Fruit and vegetable
juices, nutritional supplements, etc)
• Ingredients processing (Egusi shelling, ukwa, etc)
Case Study: Food Processing – Massive opportunity area
• High demand for food produce and products
• Alarming high cost of food in Nigeria
• Low productivity in produce value chains
7. Case Study: Food Processing – Process System Approach
Size reduction Filtration Clarification Drying Packaging
Extraction
“Poundo yam” processing plant in Ibadan (1998)
• Size reduction (Cutter) and dryer
• Packaging
Garri processing plant in Ibadan (1998) (Proposal)
• Size reduction (grinding)
• Filter, dryer, furnace
• Packaging
