Inline Instrumentation Flashcards
advantages to instrumentation and automation in the food industry?
Yield
productivity
energy utilisation
consistent quality
food safety
human safety
describe off-line as a quality measurement method
product is removed from the production line to a lab
describe at-line as a quality measurement method
product is removed from the production line and measured in the production area
describe online as a quality measurement method
may be performed in a bypass loop from the main line which allows it to return to the production line
describe In-line as an instrumental quality measurement method
performed directly on the process line without removal
which quality measurement methods are rapid
in-line nad on-line
which quality measurement method is the slowest
off-line
an example of off-line measurements
conventional micro testing
Measuring brix is an example of what kind of measurement
at -line
examples of On-line measurement
sampling concentration of material in UF unit or viscosity of material in evaporator
which measurements are known as real-time measurements
in-line and on-line
examples of in-line measurements
texture, colour, flow-meter measurements
why the need for real time sensor/instrumentation
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
characteristic of in-line sensors include
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
simple answer to what in-line sensors are used for
ensure quality and safety
main functions of in-line sensors
detection of environmental pollutants, pesticides, vet residues, toxins, pathogenic and spoilage microorganisms
optimisation
product quality
why arent bio-sensors used in in-line application
they require the addition of foreign biological material (proteins)
-antibodies to detect allergens
this will contaminate/adulterate the product
chemical and physical properties that an in-line system targets
dielectric properties
optical properties
electromagnetic properties
textural properties
general classifications for industries that require in-line systems
high scale fluid operations
large-scale manufacture of uniform products
food with retained structure
composite products
examples of high scale fluid operations
brewing, edible-oil refining, sugar and corn starch processing, and dairy operations
examples of foods with retained structure
fish and meat, fruit/veg
examples of high scale fluid operations
brewing, edible-oil refining, sugar and corn starch processing, and dairy operations
examples of composite products
confectionary and prepared meals
case study examples
in-line system used to grade carcasses (viascan measurements)
In-line colour monitoring during food extrusion
