Shenzhou Machinery - Professional Industrial Centrifuge Machine Manufacturer and Centrifugal Separators Supplier in China
Tubular centrifuges, leveraging strong centrifugal force generated by high rotational speeds, are core equipment for separating animal plasma and blood cells. They enable efficient and hygienic separation of the two components and are widely used in the deep processing of animal blood (e.g., plasma protein extraction, blood cell product processing, etc.).
The separation core of a tubular centrifuge is its high-speed rotating tubular bowl (typically with a rotational speed of 15,000–25,000 rpm and a centrifugal force of 12,000–16,000 G).
Anticoagulated animal blood enters from the bottom of the bowl. Under the action of high centrifugal force, blood cells (red blood cells, white blood cells, etc.)—which have higher density—are quickly thrown to the inner wall of the bowl, gradually depositing to form a solid layer.
Plasma (containing proteins, water, etc.)—with lower density—remains in the center of the bowl, forming an inner liquid layer that is continuously discharged through the overflow port at the top of the bowl.
During the separation process, separation precision can be controlled by adjusting the feed rate and bowl rotational speed, ensuring no obvious blood cell residue in the plasma or excessive plasma entrainment in the blood cells.
II. Key Application Scenarios and Advantages
1. Animal Plasma Separation (Mainstream Application)
Application Scenarios: Used for plasma extraction from the blood of livestock such as pigs, cattle, and sheep. The extracted plasma can be further processed into plasma protein powder (for feed, food additives, etc.), immunoglobulins, and other products.
Core Advantages:
High separation efficiency: A single unit can process 100–500 liters of animal blood per hour, meeting the capacity requirements of small and medium-sized blood processing plants.
High plasma purity: The separated plasma has low turbidity (usually ≤ 5 NTU) and no visible blood cells, satisfying the purity requirements of subsequent purification processes for raw materials.
Hygienic compliance: Parts in contact with materials are made of 316L stainless steel, and the inner wall has a polishing precision of Ra 0.4 μm, complying with food-grade and pharmaceutical-grade hygiene standards to prevent blood contamination.
2. Animal Blood Cell Separation and Recovery
Application Scenarios: Separated blood cells can be further processed into blood cell powder (for feed protein supplementation), heme, porphyrin, and other products, realizing the full-component utilization of blood.
Core Advantages:
High blood cell recovery rate: Strong centrifugal force minimizes plasma entrainment in blood cells (plasma residue rate is usually ≤ 5%), increasing blood cell yield.
Continuous operability: Some tubular centrifuges support continuous feeding and continuous plasma discharge, while blood cells are discharged through periodic shutdowns (or automatic slag discharge mechanisms), balancing continuity and operational convenience.
III. Key Operational Points in Application
Blood Pretreatment: Before separation, anticoagulants (e.g., sodium citrate, EDTA) must be added to animal blood to prevent coagulation; meanwhile, impurities such as hair should be removed by filtration to avoid clogging the bowl’s feed port or affecting separation precision.
Parameter Adjustment: Adjust the rotational speed according to the type of blood (e.g., pig blood, cattle blood—blood cell density varies slightly). For cattle blood (with slightly higher blood cell density), the rotational speed can be appropriately reduced; for pig blood, it can be moderately increased to balance efficiency and energy consumption.
Equipment Cleaning: After each use, the inner wall of the bowl must be cleaned sequentially with clean water, alkaline cleaning agents (e.g., NaOH solution), and acidic passivators to prevent blood scale residue and bacterial growth, which could affect the hygiene of subsequent separation.
Type of Separation Equipment | Tubular Centrifuge | Disc Centrifuge | Plate and Frame Filter Press |
| Centrifugal Force | High (12,000–16,000 G) | Medium (3,000–6,000 G) | Low (pressure-dependent) |
| Separation Precision | High (no blood cells in plasma) | Medium (may contain a small amount of fine blood cells) | Low (plasma tends to be turbid) |
| Processing Capacity | Medium (100–500 L/h) | High (500–2,000 L/h) | Low (50–150 L/h) |
| Applicable Scenarios | Small and medium-sized plasma/blood cell separation with high purity requirements | Large-scale centralized blood processing plants | Simple blood cell filtration with low purity requirements |
Would you like me to organize a template of operational parameters for animal plasma separation using tubular centrifuges? It will include key parameters such as rotational speed, feed rate, and anticoagulant addition ratio corresponding to different types of animal blood (pig/cattle/sheep), for your direct reference in practice.
