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
The Blood drying plant includes the following steps:
- Unloading from truck using mechanical diaphragm pump.
- Blood filter, automatic, self-cleaning.
- Second pump transport to blood tank.
- Storage in stainless tank for up to 24 hours.
- Feed metering pump to the process.
- Live steam-heated controlled coagulator (ASTW vortex design).
- Decanter for solids separation. Stick water is thrown away to waste water plant.
- Drying to blood meal in steam heated stainless steel disc dryer.
- Meal handling, cooling, hammer milling and bagging.
- Vapor cleaning in dust water scrubber, condensing of vapor in a shell and tube condenser with cooling tower, optional bio filter to remove final smell
