A byproduct of the meatpacking industry, blood has high nutritional value when properly processed. This has driven growing interest in recovering this byproduct through atomization in a spray dryer. Understand how this technology helps preserve powdered animal blood, allowing it to be used in food products, animal feed, and fertilizers.

Animal Blood: A More Common Use Than You’d Think

Rich in protein, animal blood is one of the most important byproducts of poultry, swine, and cattle slaughter in meatpacking plants. The animal recycling industry is a major user of this byproduct, using it as a raw material to produce blood meal and high-performance feed ingredients.

For these uses to be viable, the fluid blood must be turned into powder. The industrial spray dryer is the most efficient solution for carrying out this conversion quickly, while preserving the integrity of heat-sensitive proteins.

Using the Spray Dryer to Process Powdered Blood

Bovine blood deteriorates quickly and undergoes natural coagulation. During the bleeding stage, using anticoagulants like sodium citrate is essential to maintain the nutritional properties and industrial yield.

For conversion into powder, spray drying via a spray dryer is the method recommended by international agricultural organizations, such as the FAO, due to its ability to ensure the microbiological stability of the final product.

The process takes place inside a closed chamber where the product is sprayed into droplets. Upon contact with a hot air stream, immediate evaporation occurs, turning the liquid into solid particles in just 4 to 6 seconds. This extremely short time prevents heat from altering the nutritional quality of the blood proteins.

Technical and Economic Advantages

The Globe Systems spray dryer is designed to maximize thermal efficiency. Unlike other methods, introducing hot air doesn’t harm the input material. In addition, spray drying enables:

• Logistics Savings: A drastic reduction in weight and volume, making transport easier.
• Storage Stability: A dry product with low water activity, preventing fungi and bacteria.
• Excellent Cost-Effectiveness: An automated, continuous process.

Mass Balance and Efficiency in Industrial Drying

Implementing a spray dryer system requires a rigorous mass and energy balance calculation. At Globe Systems, we focus on optimizing fuel and electricity consumption per kilogram of evaporated product. Our projects follow NR-12 safety standards and global hygiene standards, ensuring a clean, safe process for animal recycling.

By investing in atomization technology, your industrial plant not only reduces the environmental impact of waste disposal but also creates a new revenue stream from high-value byproducts for the global animal nutrition market.
