BLOOD PLANT
A & S THAI WORKS CO., LTD
Continuous drying of fresh blood to blood meal.
Blood is a valuable, high protein (~ 80%) raw material, but with high water content and low meal yield, typically 13-15%.
Blood meal is sold to animal feed producers (feed mills), or mixed in with the meat and bone meal process.
Using a decanter and a disc drier, ASTW provides a cost-effective method for the production of blood meal.
The indirectly heated disc dryer gives a continuous drying process, specially designed to handle difficult and sticky materials
