Presentation Transcript

  1. OBJECTIVES - PROCESS FLOW SHEET MODULE • KNOW WHAT A PROCESS FLOW SHEET IS • UNDERSTAND THE NEED TO OPTIMIZE PROCESS CONDITIONS • LEARN THE BASIC CONCEPTS OF FOOD SAFTEY AND GOOD MANUFACTUREING PROCESSES

  2. KEY DEFINITION • A FLOW CHART IS A SCHEMATIC DEPTICTION OF THE PROCESS REQUIRED TO MAKE A GIVEN PRODUCT. IT CONTAINS ALL THE INFORMATION NEEDED FOR PROCESS SCALE-UP, DESIGN AND COST ESTIMATION

  3. ELEMENTS NEEDED TO DEFINE A PROCESS • UNIT OPERATIONS • Design Criteria • Geometry • OPERATING CONDITIONS • Fundamental and Calculated • Critical Control Points • MATERIALS OF CONSTRUCTION • MASS BALANCE • ENERGY BALANCE

  4. OBJECTIVES OF A FOOD PROCESS • STABILIZE PRODUCT • PHYSICAL • CHEMICAL • BIOLOGICAL • IMPART DESIRED PHYSICAL AND/OR CHEMICAL CHARACTERISTICS

  5. TECHNIQUES FOR STABILIZING A FOOD PRODUCT • THERMAL PROCESSING • REFRIGERATION • FREEZING • FERMENTATION • CONTROL OF WATER • ACIDIFICATION • CHEMICALS • IRRADIATION • PRESSURE • PULSED ENERGY

  6. PROCESS PARAMETERS • FUNDAMENTAL • TEMPERATURE • PRESSURE • CONCENTRATION • FLOW RATES • VELOCITY

  7. PROCESS PARAMETERS • CALCULATED OR MEASURED • TIP SPEED POWER • TORQUE • POWER/UNIT VOLUME • SHEAR RATE • TOTAL STRAIN • CIRCULATION RATE • SUPERFICIAL VELOCITY • DIMENSIONLESS NUMBERS

  8. MASS BALANCE EXAMPLE

  9. ENERGY BALANCE EXAMPLE

  10. KEY DEFINITION • SCALE UP IS THE TASK OF PRODUCING AN IDENTICAL, IF POSSIBLE, PROCESS RESULT AT A LARGER PRODUCTION RATE THAN PREVIOUSLY ACHIEVED • STAGES ARE: BENCH TOP TO PILOT PLANT TO FULL PRODUCTION PLANT

  11. KEY DEFINITIONS • THE PRIMARY SCALE-UP CRITERION IS THAT PROCESS PARAMETER, OR SET OF PARAMETERS, THAT BRINGS ABOUT THE DESIRED PROCESS RESULTS INDEPENDENT OF THE ULTIMATE SCALE OF THE PROCESS • THE SCALE-UP CRITERIA ARE THOSE MECHANICAL AND PHYSICAL CHANGES THAT MUST BE UNDERSTOOD TO SATISFY THE PRIMARY SCALE-UP CRITERION

  12. SUCCESS REQUIRES • COMPLETE UNDERSTANDING OF THE ROLE OF EVERY STEP IN THE PROCESS • GENERALLY REQUIRES THE APPLICATION OF EXPERIMENTAL DESIGN TO UNDERSTAND FACTORS AND INTERATIONS INVOLVED IN THE PROCESS
