Flour
Flour Milling is typically milled with a number of properties in mind, one of them being colour.
Historically a Spectral Categorisation was used which had two major impediments:
- Spectral Data can reflect the Colour Hue for instance a Yellow or Orange shade, but not describe the true colour properties in full detail.
- Inter Instrument agreement was poor requiring a central moderating facility to evaluate a physical sample versus the grading it was given. This grading could then be modified to suit other colour grades, according to a central standard.
Narich (Pty) Ltd, working together with the Milling Industry, The South African Grain Laboratory and Instrument Supplier Konica Minolta have come up with a now tried and tested reliable application. The main components are:
- A Konica Minolta Spectrophotometer CM-5. :- This Instrument offers a quick and easy to operate measurement with a very high degree of repeatability and inter-instrument agreement. Typically this top end instrument is used in the main or R&D laboratory to set standards and monitor the group measurements.
- SpectraMagic NX Pro :- An affordable Microsoft Windows compatible ISO standard software to set standards, manage all sample data, and ensure accurate template settings for each task. A key feature is the ability to delete a bad measurement, but not EDIT any measurements.
- Suitable easy to use accessories for quick and easy colour grading. Values are returned in internationally standardised CIE units.
- Production sites can replicate the colour grading readings with an in-mill less expensive version of the CM-5, namely the Konica Minolta Colorimeter CR-5. Offering the same levels of accuracy and reliability, this device also includes on board Firmware negating the need for a PC in the mill. Additionally, a local Plain Paper Printer can be attached to print Job Tickets on the fly.
