Efficient Animal Blood Processing System: Centrifugation, Membrane Filtration, and Protein Powder Production

Efficient Utilization of Animal Blood: Advanced Separation, Membrane Concentration & Drying Technology for High-Value Protein Powder Production

In the global rendering and animal by-products processing industry, animal blood resource valorization has become a core development trend. Driven by growing demand for sustainable protein raw materials and zero-waste circular economy solutions, converting waste animal blood into stable, high-value protein powder has evolved from an optional upgrade to an essential production link for modern meat factories.

This article introduces our complete industrial animal blood processing system, details the full production workflow, and analyzes its environmental protection and economic benefits for rendering plants.

Core Processing Purpose

Our integrated system takes fresh slaughterhouse animal blood as raw material to produce stable, easy-to-transport high-protein powder products, mainly including:

• Spray-dried blood plasma powder

• Refined blood cell protein powder

• High-nutrition feed-grade protein additives

The whole production line achieves four core advantages:

• 100% full resource utilization of animal blood waste

• Sharp reduction of slaughterhouse organic wastewater pollution

• High protein recovery rate via membrane separation technology

• Greatly extended shelf life of finished blood protein powder

It is tailor-made for medium and large meat processing factories, rendering plants and animal by-product recycling workshops.

⚙️ Complete Industrial Process Workflow

The full set of blood powder production equipment runs through 7 standardized processing stages:

1. Fresh Blood Collection & Anticoagulant Storage

   Fresh animal blood is centrally collected and stored in insulated constant-temperature tanks with anticoagulant dosing to avoid early coagulation and guarantee raw material activity.

2. Tubular Centrifuge Solid-Liquid Separation

   Tubular separation centrifuge quickly splits mixed blood into two independent fractions:

• Protein-rich plasma liquid

• Concentrated red blood cell liquid

  This step completes primary high-speed solid-liquid separation to lay the foundation for high-purity protein extraction.

3. Ultrafiltration Membrane Concentration System

   Plasma liquid enters our cross-flow membrane filtration concentration unit:

• Remove redundant free water efficiently

• Realize targeted protein molecular interception & concentration

• Lower energy consumption of subsequent drying procedures

  Core tech: cross-flow membrane separation, industrial ultrafiltration, continuous protein concentration system

4. Buffer Circulation Tank for Production Stabilization

   Concentrated protein liquid is temporarily stored in circulation buffer tanks to stabilize liquid concentration and realize uninterrupted continuous production.

5. Precision Polishing Filtration

   Secondary bag/cartridge fine filter removes tiny suspended impurities to improve finished powder purity and uniformity.

6. Low-Temperature Drying Unit

   Purified concentrated protein liquid is sent to spray dryer or drum dryer for moisture removal; low-temperature drying retains original protein activity.

7. Finished High-Value Protein Powder

   The final powder products can be widely applied in:

• Livestock & aquaculture feed formulations

• Food-grade protein supplement additives

• Biological fermentation & bioprocessing raw materials

Core Advantages of Our Animal Blood Recycling Technology

1. Sustainable Alternative Protein Production

   Our membrane concentration system helps factories develop self-sufficient protein raw materials, lowering dependence on imported soybean meal and fish meal.

2. Circular Economy for Slaughter Waste

   Turn slaughter waste blood into profitable high-value products, fully complying with global zero-waste manufacturing and circular economy standards.

3. Significant Environmental Pollution Control

   Standardized closed blood processing avoids random discharge of organic waste, cutting wastewater COD load, organic waste stacking and malodorous decomposition gas emissions.

4. Integrated High-Efficiency Production Line

   Combined tubular centrifugation + membrane ultrafiltration + low-temperature drying integrated technology brings obvious improvements: higher protein yield, stable finished product quality, flexible production capacity scaling for small to large factories.
