Forberg® Heat Treatment System

Premium Layer’s Mash Feed for Specific Pathogen Free Farms – SPF Farms

The Forberg Steam Heat Treatment System is used for production of premium feed for layers. Heat treatment of mash feed kills salmonella and significantly reduces bacterial spores. The final product is a high quality feed with a perfect structure for the layers. Research has proven better suitability of mash feed compared to pelleted and crumbled feed.

Coarsely ground grains, with an ideal structure for layers, are steamed in the Forberg® Mixer/Conditioner equipped with steam nozzles. While the components are mixed to perfect homogeneity and steam is injected, the Forberg® Mixer heats the product to the desired temperature above 86°C. The temperature is maintained over a certain period of time to kill salmonella and other pathogens.

After the heat treatment, the Forberg® Mixer discharges directly into a Forberg® Dryer/Cooler. In the Forberg® Dryer/Cooler, the moisture and temperature are brought back to the desired levels. The product is dried/cooled by blowing hot/cool air through the mechanically fluidized product. The reliable and repeatable process gives the same perfect quality product after each batch. After drying and cooling, heat sensitive components such as vitamins, enzymes, acids, flavor or pharmaceuticals can be added.

The mixture is now ready for packaging, bulk loading or intermediate storage.

Advantages of heat-treated mash feed compared to traditional pelleting and crumbling:

  • A batch rather than continuous system to ensure every particle is heat treated
  • Designed as a compact, vertical system to avoid any product accumulation
  • Micro agglomeration of the feed binding smaller particles together
  • Higher inclusion level of fat & oil
  • Addition of vitamins and enzymes after the heat treatment
  • Better health, behavior and performance of the flocks
  • Birds need more time for feed intake, which is beneficial in terms of bird behavior
  • Energy efficient
