Pre Treatment Processes

  1. 1. Pretreatment Techniques In Oil Refining
  2. 2. Outline • Pretreatment Process • Why Pretreatment Process? • Activity of Enzymes • Various Pre Treatment Process • Statistics and Graphs • Conclusion
  3. 3. What is a Pretreatment Process? • Raw • Pre • Oil Material Treatment Extraction Process • Effective handling of the batch • Efficient Extraction Of Oil
  4. 4. 1.Receiving and Storage Sample AnalysisTrainShip Receiving Drying StorageBargeTrucks Seed Preparation
  5. 5. 2. Preparation for ExtractionSeed From Process Scaling Cleaning Storage Drying Heat Dehulling Cracking Treatment Extraction Flaking Process Cooking
  6. 6. Activity of Enzymes Lipase • Free Fatty Acids • Increase Secondary Lipoxy Oxidation Products Genase • Increase the Non Phospho Hydra table Lipase Phospho Lipids
  7. 7. Why Pretreatment Process? Decrease wear and tear of Process equipment Efficient and Effective extraction of oil Inactivation of Enzymes
  8. 8. Sources of Edible oils
  9. 9. World wide Top 10 Oil Productions
  10. 10. Ground Nut
  11. 11. Oil Content in Fruits and Kernels 70 60 50 Oil 40Content 30 20 10 0 Olive Palm Palm Kernel Coconut Fruits
  12. 12. Oil Content in Seeds 50 45 40 35 Oil 30Content 25 20 15 10 5 0
  13. 13. Fruit Reception
  14. 14. Sterilization
  15. 15. Canola Oil
  16. 16. Cleaning Electro Oversize Undersize Magnetic Screening Screening Screening
  17. 17. Heat Treatment Heated : 30-40 C • Fluid Bed Type Dryers • Rotary Kilns with steam heated coils  More Pliable  Less Likely to shatter Fluid Bed Type Dryers  Reduce the moisture
  18. 18. Flaking rollsFlaking Flakes: 0.4 - 0.7 mm • Single stage flaking rolls • Double stage flaking rolls  Fractures the starch matrix  Ruptures the cell walls  More efficiently oil is leached out in subsequent solvent extraction
  19. 19. Cooking• Heated : 75-100 C• Ambient Air : 5-7% Moist Rotary Cookers Stacked Cookers Stack Cookers
  20. 20. Coalesces minute oil droplets into largerFacilitate oil and meal separationInsolubilisation of Phospholipids (Phospholipase) Increased fluidity of the oil Inactivation of enzyme (Myrosinose)
  21. 21. RBD Canola OilCrude Canola Oil Bleached Refined
  22. 22. Pre Treatment Process Heat Cleaning Flaking Treatment De Dehulling Cooking Shelling Drying Cracking Extraction
  23. 23. De Hulling Process Hulled Dehulled1.Increases Efficiency Dehulling Machine2.Increase the Capacity of Extraction Equipment3.Reduce wear and tear of Equipment
  24. 24. RBD Peanut Oil Crude Peanut Oil RBD Peanut Oil Groundnut oil Cake
  25. 25. Increase In FFA Lipolytic Enzyme
  26. 26. Quality of Bran Rice Variety Treatment of Grain Type of Milling Degree Of Milling
  27. 27. Rice Bran to Oil
  28. 28. Stabilization • Arrest lipase and lipoxy genase activity • Improve oil extraction efficiency • Reduce fines in crude oil • Reduce color development
  29. 29. Pelletization1. Rice Bran Converted to pellets of uniform size Pellets2. Diameter ranges 6-8 mm3. Pelletization makes process efficient for oil extraction. Refined Rice Bran Oil
  30. 30. Sun Drying • Kernels are separated from Shell • Drying 6-8 Days • Moisture 50% -- 6-8%
  31. 31. Hot Air Drying
