Inline Instrumentation

Question 1

advantages to instrumentation and automation in the food industry?

Answer 1

Yield
productivity
energy utilisation
consistent quality
food safety
human safety

Question 2

describe off-line as a quality measurement method

Answer 2

product is removed from the production line to a lab

Question 3

describe at-line as a quality measurement method

Answer 3

product is removed from the production line and measured in the production area

Question 4

describe online as a quality measurement method

Answer 4

may be performed in a bypass loop from the main line which allows it to return to the production line

Question 5

describe In-line as an instrumental quality measurement method

Answer 5

performed directly on the process line without removal

Question 6

which quality measurement methods are rapid

Answer 6

in-line nad on-line

Question 7

which quality measurement method is the slowest

Answer 7

off-line

Question 8

an example of off-line measurements

Answer 8

conventional micro testing

Question 9

Measuring brix is an example of what kind of measurement

Answer 9

at -line

Question 10

examples of On-line measurement

Answer 10

sampling concentration of material in UF unit or viscosity of material in evaporator

Question 11

which measurements are known as real-time measurements

Answer 11

in-line and on-line

Question 12

examples of in-line measurements

Answer 12

texture, colour, flow-meter measurements

Question 13

why the need for real time sensor/instrumentation

Answer 13

consumer demand for higher and more consistent quality
production capacity increased
shifting of HACCP to proactive and preventative rather than reactive
need for longer shelf life
increased continuous processing rather than batch operations

Question 14

characteristic of in-line sensors include

Answer 14

accuracy and sensitivity
no hygiene comprimise
not disrupt the process and change the quality
low maintenance and automatic
total cost is proportionate to that gained

Question 15

simple answer to what in-line sensors are used for

Answer 15

ensure quality and safety

Question 16

main functions of in-line sensors

Answer 16

detection of environmental pollutants, pesticides, vet residues, toxins, pathogenic and spoilage microorganisms
optimisation
product quality

Question 17

why arent bio-sensors used in in-line application

Answer 17

they require the addition of foreign biological material (proteins)
-antibodies to detect allergens
this will contaminate/adulterate the product

Question 18

chemical and physical properties that an in-line system targets

Answer 18

dielectric properties
optical properties
electromagnetic properties
textural properties

Question 19

general classifications for industries that require in-line systems

Answer 19

high scale fluid operations
large-scale manufacture of uniform products
food with retained structure
composite products

Question 20

examples of high scale fluid operations

Answer 20

brewing, edible-oil refining, sugar and corn starch processing, and dairy operations

Question 21

examples of foods with retained structure

Answer 21

fish and meat, fruit/veg

Question 22

examples of high scale fluid operations

Answer 22

brewing, edible-oil refining, sugar and corn starch processing, and dairy operations

Question 23

examples of composite products

Answer 23

confectionary and prepared meals

Question 24

case study examples

Answer 24

in-line system used to grade carcasses (viascan measurements)
In-line colour monitoring during food extrusion
