SpectraAlyzer DAIRY – Dairy Product Analysis and Quality Check

SpectraAlyzer DAIRY

The SpectraAlyzer DAIRY is a dairy analyzer and quality check instrument, which is the ideal solution for routine analysis of major quality parameters during the production of dairy products.

In modern dairy processing operations, reliable and accurate dairy analysis solutions are necessary to provide customers with products of highest and – what is most important – consistent quality. In order to be most competitive in the world market, consistent high yields, top quality and low production costs are the objectives that need to be achieved.

Designed as a modular system, the SpectraAlyzer DAIRY solution presents the quantitative analytical results of major quality parameters (e.g. moisture, protein, fat, sugars, starch, acidity, salt, ash) and many others within 45 seconds. There is no need to manually condition the sample and extra reagents do not have to be used so this analyzer solution provides highly accurate quality control parameters at no extra cost.

As a stand alone system, the SpectraAlyzer DAIRY can be operated very easily and intuitively for dairy analysis and quality check, even close to the production line. The rugged construction and unique optical sample/reference setup ensures reliable operation in environments with fluctuating temperatures, vibrations and dust.

The SpectraAlyzer DAIRY analyzer comes with many ready to use calibrations and a powerful software package to facilitate calibration fine tuning and extensive and automated logging as well as database storage of the analytical results on the analyzer, within the company intranet and/or the internet.

like all SpectraAlyzer® instruments for high sensitive and long term stable measurements.

Versatile sample presentation

by means of a syringe, a pump, or an autosampler.

User friendly

sample presentation and easy to operate.

Compact design

optimised for bench top or at-line application.

Touch user interface

and intrinsically mounted glass touch for straight forward hygenic instrument operation.

Many mathematical models

for all kind of products included for quick calibration models installation and start-up.

Web server

web connectivity for direct instrument access via LAN and internet from anywhere, any time.

SpectraAlyzer analytical solutions for Milk powder analysis


Optimization of processing tolerances during the production of skim milk powder

Maximize profit by increasing water content in milk powder, decreasing labour costs and improving product quality



Production Plant250 d/a
Production Plant20 h/d
Milk Powder production2000 kg/h
Total Production10000 t/a

Product specifications

Water content3,7 %
Permitted Water content4,0 %
Safety difference0,3 %


The monitoring of the water content in skim milk powder with NIR technology allows the continuous production of skim milk powder with a water content of for example 3,9 % instead of 3,7 %.

Savings in production costs per year: raw material and wages


Production cost reduction per year:

  • 20 t skim milk powder will be saved per year

Skim milk powder savings / year – € 40.000

  • Less routine production analysis is necessary
  • Cost for reduced labour to be quantified
