The need for recycling of animal blood from slaughterhouse

Animal blood from slaughterhouse is a cause of environmental contamination and a major contributor to the cost
The disposal of animal blood and by-products from slaughterhouse will involve the heavy expenses
More investment on wastewater treatment facilities is required by intensified environment standards
The operation of slaughterhouse will be difficult due to more investment on wastewater treatment facilities

Cost of wastewater treatment in a LPC (Livestock Processing Complex)

Research and development on mass use of animal blood is badly needed.
Studies on feed stuff using hot-air dried blood were reported but there is no study on feed stuff using spray dried blood.
Animal blood is high in protein and has a good possibility to be used as additives for formula feed and fish feed.

Technology of Air pocket formation
Mix organic (blood) and mineral (Macsumsuk) in the ration of 3.8 to 6.2 by activated sludge process and input them in the manufacturing device for granule. Air pocket is formed inside the ring shape as result of instant expansion of granular particle and moisture evaporation by 200ºC ~250ºC of internal heat.
Coating technology in the surface of granule
Granular Surface of Protein substance (blood) is instantly coated through the process of spray drier by 200ºC ~250ºC of internal heat.
