Dinnissen develops method to protect additives from oxidation

Dinnissen Process Technology in the Netherlands is developing a new method to protect liquid as well as powdered vitamins, enzymes, pre- and probiotics against oxidation.

Micro-ingredients such as vitamins, enzymes, pre- and probiotics play a crucial role in concentrated feeds and diet feeds.

However, these micro-ingredients which are added to feed pellets in only minute amounts are very fragile as contact with oxygen causes certain nutritional compounds to become oxidized and lose much of their effectiveness.

This can easily happen during the transport and storage of the pellets.

Dinnissen's Pegasusa Mixer makes it possible to spray vitamins, enzymes, pre- and probiotics in predefined and very accurate quantities onto the surface of cattle feeds.

After being sprayed onto the pellets, the tiny quantities of micro-ingredients are transported deep inside the pellet with the help of the special Pegasusa Vacuum Coater, thereby protecting them from falling off and from contact with oxygen.

Henri Michiels, company director, said the company seeks to improve the effectiveness of cattle feeds with this new technology.

The new method creates opportunities in the feed sector to develop improved feed products and to reduce the use of aggressive acids, Michiels added.

Dinnissen is a machine specialist for the compound feed industry and is a leading player on products and tailor-made solutions for powders, particles and granules.
