1 - Materials Flow Through the Mill Flashcards
(15 cards)
What is the wheat flow
Intake test, preliminary cleaning, raw wheat bins/silos, cleaning in screenroom
What are the upper and lower ranges categorised by on intake
Protein
Hagberg falling number
specific weight
What happens to graded wheat
Transferred to separate bins in the silo and blended
Why is it good to blend graded wheat
Reduces variations to a minimum
What happens to finished products at the end of the mill flow
Stored in hygienic conditions
Easily accessible for outloading as bulk or bagged products
Why are flours blended in bins prior to despatch in bulk
Finished product can be blended to exact customer requirement
Fluctuations from milling are minimised
Savings made as no need to mill with a safety factor
Grist changes minimised
Mill can be set up more efficiently
Criteria can be met to a specification target - colour grade, water absorption, protein content
How is blending from component bins acheived
Use of variable speed dischargers feeding into a mixing conveyor
What is a more expensive method of blending from component bins
Variable speed dischargers with a batch mixer
Label a mill process flow
Look at diagram
T/F Wheat is usually stored in the silo before any cleaning takes place

Preliminary cleaning
Which can be termed ‘raw materials’
Wheat, additive ingredients
Impurities removed during the process of wheat cleaning are collectively termed?
Screenings
What are considered finished products
Flour, wheatfeed, wheatgerm
… is the term used to describe the process of mixing different base flours together to produce a different finished flour
