This document discusses quality control processes at dairies. It describes 5 key steps in milk production: 1) raw milk receiving where density and composition are tested, 2) raw milk tank quality checks, 3) standardized milk processing where quality is controlled, 4) standardized milk tank checks before packaging, and 5) quality control of packaged products. A variety of laboratory and process instruments are used at each step to test attributes like density, fat content, solids, and more to ensure high quality.

Milk and Dairy products: What Cows, Sheep, Goats,
Donkeys, Camels and Dairies have in common
They all produce high-quality food stuff, the latter with the help
of sophisticated analytical instrumentation.
The milk production process in a dairy involves many steps
where careful quality control is in demand, in the laboratory as
well as online.
1 Raw milk receiving: Adulteration test (addition of water)
Laboratory instrumentation: Density with DMA 35, DMA 500, and (with
pre-determined fat content) corrected lactometer reading (CLR), solids
non-fat (SNF), total solids (TS) with DMA 4100/4500/5000 M
Process instrumentation: Density with DPRn 427/S; L-Dens 437, mPDS 5,
mPDS 1100
2 Raw milk tank: Quality check before processing
Laboratory instrumentation: Density with DMA 35, DMA 500 and (with
pre-determined fat content) CLR, SNF, TS with DMA 4100/4500/5000 M
3 Standardized milk process: Process control, quality control and
assurance
Laboratory instrumentation: Density with DMA 35, DMA 500 and (with
pre-determined fat content) CLR, SNF, TS with DMA 4100/4500/5000 M
Process instrumentation: Density, CLR, SNF, TS and fat with DPRn 427/S;
L-Dens 437, mPDS 5
4 Standardized milk tank, pre-packaging: Quality control
pre-packaging
Laboratory instrumentation: Density with DMA 35, DMA 500 and (with
pre-determined fat content) CLR, SNF, TS with DMA 4100/4500/5000 M
Process instrumentation: Density and (with saved product fat content)
CLR, SNF, TS and fat with DPRn 427/S; L-Dens 437, mPDS 5
5 Packaged products: Quality control of packaged products
Laboratory instrumentation: Density with DMA 35, DMA 500 and (with
pre-determined fat content) CLR, SNF, TS with DMA 4100/4500/5000 M
