Blood Roller Mixer with 4 rollers that are
230 mm long, the following considerations are important:
Key Design Features:
Roller Length: Each of the rollers is 230 mm long. This length is important as it will determine how much blood can be processed at a time.
Roller Configuration: Since there are 4 rollers, they will typically be arranged in two parallel pairs or all in a single row, depending on the mixing requirements. The rollers should rotate in a way that allows for the blood to be evenly spread across all rollers.
Roller Speed: The rollers will rotate at a certain speed (RPM) to ensure proper mixing. Too fast, and the blood might not mix well; too slow, and the mixing process could be inefficient.
Roller Material: The material of the rollers should be compatible with blood (for safety and hygiene reasons), typically made from materials like stainless steel or food-grade plastics.
Angle and Pressure of Rollers: The rollers should apply sufficient pressure to gently squeeze the blood, ensuring that the cells in the blood are mixed thoroughly without causing hemolysis (destruction of blood cells).
Motor and Power: The motor will need to be powerful enough to rotate the rollers at the desired speed. Depending on the roller’s diameter and load, you can calculate the motor specifications.
Size of the Mixer: The entire unit will need a housing that can accommodate all 4 rollers and the motor while ensuring easy access for cleaning and maintenance.
Blood Roller Mixer Operation:
Loading: The blood is loaded into the mixer, either in a continuous stream or in batches, depending on the system design.
Mixing Process: As the rollers turn, they create a gentle shear force that helps to mix the blood evenly, making it homogeneous. The blood moves across the surface of the rollers, with the rotating action helping to mix the components thoroughly.
Exit: Once mixed, the blood can exit from the mixer either through a collection tube or outlet.
