Dry Dairy Powders and the Kek Centrifugal Sifter

Kemutec Kek Centrifugal Sifter - How It WorksDried dairy powders were first noted in the early 1300s by Marco Polo. He wrote about the Mongolian Tatar troops in the time of Kublai Khan who carried a paste-like sun-dried skim milk. Today dried dairy powders are offered in a variety of forms including whole, low fat, and nonfat milk, buttermilk, cheese, ice cream, yogurt, sour cream, and butter powder.

How is Dry Dairy Powder produced?

Milk, either whole, skim, buttermilk, etc., is concentrated in an evaporator to approximately 50% milk solids. The concentrated milk is then sprayed into a heated chamber where the water instantaneously evaporates. This process produces an end product of fine milk powder particles.

Another process, drum drying or fluid bed drying, is the process where a thin coating of dairy product is applied to the surface of a heated drum for evaporation. This process alters the properties of the dairy powder including flavor, solubility and bulk density.

The Kek Centrifugal Sifter and Dry Dairy Products

Kemutec’s Kek Centrifugal Sifter is integral to the Dry Dairy Powder Process in that it de-agglomerates and polices the dried powder before packaging.


De-Agglomeration is the process of breaking up or dispersing particles that have clumped, aggregated, or clustered together. Dry Dairy Powders can become agglomerated due to environmental conditions, weight, and fat content of the dairy powder. The Kek Centrifugal sifter de-agglomerates the powder in preparation for further processing.


The Kek Centrifugal Sifter is also used to police or the check sifting of the bulk dry product to remove extraneous materials and unwanted items.

The Kek Centrifugal Sifter is also in service for:


The removal of fines generated during processing and handling that will otherwise spoil the appearance of a packed product or cause a problem during subsequent processing.
