How are tubular centrifuges used to purify vaccines and fruit juices?

Tubular centrifuges are utilized for the purification of vaccines and fruit juices by leveraging high centrifugal fields to separate materials based on density and particle size.1

In these applications, the centrifuge operates by passing the feed material through a long, hollow rotating tube. As the fluid flows from one end to the other, the high-speed rotation subjects the mixture to intense centrifugal forces, causing sedimentation of heavier components.1

• Vaccines: Unprocessed vaccines often contain nonessential and harmful materials. The tubular centrifuge effectively separates these impurities from the desired biological product.1
• Fruit Juices: The instrument is used for the clarification and purification of food products, including fruit juices, by removing fine particles and other unwanted substances to improve product quality.1

Because the separation process is not always complete in a single pass, the material may be cycled through the machine multiple times. If the target material consists of very fine particles at low concentrations, the machine may be operated as a batch-type centrifuge, allowing the solids to deposit on the tube wall.1
