Description
The milk fat content is standardised in a direct standardisation system. Standardised milk used for producing whole milk powder is not normally homogenized.
Features
Falling-film
evaporators are generally used for concentration, which is carried out
in two or more stages to a DS content of 45 – 55%.
Two-stage drying
The
last traces of moisture are the most difficult to remove, unless high
outlet drying temperatures are used to provide a sufficient driving
force. As elevated outlet drying temperatures can have a detrimental
effect on powder quality, it is essential to operate at lower outlet
temperatures with dairy products. If the moisture content of the
resulting powder is still too high, an after-drying stage is
incorporated after the spray dryer in a two-stage process as illustrated
in figure .Two-stage drying methods for producing powdered milk product
combine spray drying as the first stage and fluid bed drying as the
second stage. The moisture content of the powder leaving the chamber is 2
– 3% higher than the final moisture content. The function of the fluid
bed dryer is to remove excess moisture and finally to cool the powder
down.
The powder is packed in cans, paper bags, laminated bags
or plastic bags, depending on the quality and the requirements of the
consumers.
Milk powder production requires the drying of liquid
milk into a powder in which aromas, flavours and colouring as well as
many important components such as protein, fat, carbohydrate, vitamins,
minerals etc. are retained. Additional challenges is a uniform moisture
content, particle structure and particle size distribution, solubility,
dispersability and wettability.
Benefits
