20 Years ago the first colour measurement has been installed in
the Danish Assens factory

Today more than 100 instruments are installed all
over the world

Process control is the method to keep the process and the quality of the final product inside the targets, by controlling and regulating various process parameters

• Leaving syrup on the crystals reduces pol, increases ash and leads to caking
• A combination of the two above (very common)
How centrifugals influence sugar quality
The centrifugals influence the sugar quality and the mill profit in 3 ways:
Overwashing dissolves good sugar, generates more molasses and decreases capacity
![Page 13: Importance of in-line colour measurement of sugar for product quality and factory performance By Tim Diringer and Bjarne Christian Nielsen Copyright Neltec](https://reader038.vdocuments.us/reader038/viewer/2022110206/56649cf05503460f949bef12/html5/thumbnails/13.jpg)
Nowhere in processing
can so much sugar
be lost so quickly
and with so little notice
as in centrifugation
![Page 14: Importance of in-line colour measurement of sugar for product quality and factory performance By Tim Diringer and Bjarne Christian Nielsen Copyright Neltec](https://reader038.vdocuments.us/reader038/viewer/2022110206/56649cf05503460f949bef12/html5/thumbnails/14.jpg)
To avoid sugar losses the operator must see the result of the centrufigation process and act accordingly
![Page 15: Importance of in-line colour measurement of sugar for product quality and factory performance By Tim Diringer and Bjarne Christian Nielsen Copyright Neltec](https://reader038.vdocuments.us/reader038/viewer/2022110206/56649cf05503460f949bef12/html5/thumbnails/15.jpg)

A factory with an output of 1200 t/d raw sugarproduces 50 t raw sugar per hour
50g of sugar are used for the analysis
This is 0,000050 % of the total amount of sugar
If a sample for determing the colour in soloutionIs taken every 2 hours
![Page 20: Importance of in-line colour measurement of sugar for product quality and factory performance By Tim Diringer and Bjarne Christian Nielsen Copyright Neltec](https://reader038.vdocuments.us/reader038/viewer/2022110206/56649cf05503460f949bef12/html5/thumbnails/20.jpg)

On-line measurement of each batch centrifugal
tells something about origin of errors.

Improvements at Manildra-Harwood Mill
• Amount of sugar within the specs increased
![Page 39: Importance of in-line colour measurement of sugar for product quality and factory performance By Tim Diringer and Bjarne Christian Nielsen Copyright Neltec](https://reader038.vdocuments.us/reader038/viewer/2022110206/56649cf05503460f949bef12/html5/thumbnails/39.jpg)
Improvements at Manildra-Harwood Mill
• Molasses purity was reduced from 44 to 41
![Page 40: Importance of in-line colour measurement of sugar for product quality and factory performance By Tim Diringer and Bjarne Christian Nielsen Copyright Neltec](https://reader038.vdocuments.us/reader038/viewer/2022110206/56649cf05503460f949bef12/html5/thumbnails/40.jpg)
Improvements at Manildra-Harwood Mill
• The amount of massecuite required to produce 100 tons of sugar was reduced from 200 tons to 195 tons
![Page 41: Importance of in-line colour measurement of sugar for product quality and factory performance By Tim Diringer and Bjarne Christian Nielsen Copyright Neltec](https://reader038.vdocuments.us/reader038/viewer/2022110206/56649cf05503460f949bef12/html5/thumbnails/41.jpg)
To rely on the data collected inline, the following aspects must be fullfiled:
Accuracy of the instrument
Reliability of the calibration
![Page 42: Importance of in-line colour measurement of sugar for product quality and factory performance By Tim Diringer and Bjarne Christian Nielsen Copyright Neltec](https://reader038.vdocuments.us/reader038/viewer/2022110206/56649cf05503460f949bef12/html5/thumbnails/42.jpg)
Lab control in a refinery
![Page 43: Importance of in-line colour measurement of sugar for product quality and factory performance By Tim Diringer and Bjarne Christian Nielsen Copyright Neltec](https://reader038.vdocuments.us/reader038/viewer/2022110206/56649cf05503460f949bef12/html5/thumbnails/43.jpg)
To ensure product quality, in line measurement is necessary
In line colour measurement helps the operators to understand the
process
Time span from occuring to solving of a problem is reduced
dramatically
Capacity increases and sugar losses decrease
