Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Formed when one substance of very small particle size is dispersed through another substance and the two substances are immiscible






2. 3 things used for size reduction






3. Creates lots of heat - main force are shear action






4. Pressure- pushing but not dynamically loaded






5. Loss of soluble components (e.g. sugar) - Cost of water and water disposal - Accelerate microbial/biological degradation






6. Separate products by size






7. The amount of energy it takes to change the state






8. What factors affect the degree of mixing that can be achieved with dry powders or particulate solids?






9. Used to mill wheat- cereals and flours






10. Swirls in the flow






11. The breakdown of solid material through the application of mechanical forces- size reduction






12. Paddle - Multiple Impeller - Turbine - Propeller






13. Mixing component that is undesired






14. Multiple paddle agitators - Planetary/Orbital - Z-Blade - Rotor-Stator






15. Each thing we do to prevent degradation is one hurdle- name an example- packaging






16. Used to be was dividing things on one characteristic






17. Mass






18. Used to chop meat and harder fruits and veggies into pulp






19. Efficient (minimize losses) - Low Cost - No product degradation






20. Size reduction equipment in order of decreasing size






21. Ratios above 100:1






22. Not always effective (attached soil) - Can be dusty (explosion hazard) - Recontamination hazard - Can damage product






23. Linear






24. Deformation or stretch- change in length divided by the original length






25. = (vol of foam - vol liquid)/vol liquid) x 100






26. Ingredients in mayo






27. The ability to form a homogenous mixture






28. Helps prevent blinding






29. Involves tumbling in a drum with a silicon carbide or carborundum surface






30. Pseudoplastic






31. Amount of energy from solid to liquid and vice versa






32. To achieve a uniform distribution of the components of flow






33. Linear relationship between sheer rate and sheer stress






34. Energy from liquid to gas and vice versa






35. 3 components of mixing liquids






36. Ability to deform permanently without breaking






37. Measures specific gravity






38. = mass of liquid






39. Soaking tanks (with or w/o stirring/paddles) - Flotation washing (fluming) - Spray washers (belts - drums) - Brush washers - Ultrasonic cleaners






40. Placed at goods intake - Before and after a unit operation - At the end of a line






41. Shear and impact forces - used for spice manufacturing - 70:30 impact predominated






42. Generally used for products with high mechanical strength and low moisture - Relies on density and area difference






43. A fluid suspension of a colloidal solid in a liquid






44. Velocity gradient that is formed- relative rate between the layers






45. Tumbling action inside a rotating vessel - Screw type - Double Reversing agitators






46. Leavening agent- breads have the yeast with CO2 giving us the lift in the bread- want this to take place before the breaking - Biscuit- leavening agent - chemical reaction- lots take place during baking process






47. Track what goes into a system- account for everything that comes out minus what stays in the system






48. Advantages: Rapid cooling; can handle large quantities; prevents dehydration - Disadvantages: Can encourage diseases; not all products tolerate wetting; restrictions on packaging and stacking arrangements; capital costs can be high






49. Dividing based on several characteristics capable of automatically






50. Distance between rollers
