A centrifugal separator includes a rotating body driving and sealing structure in which a hermetically sealed space is formed between a rotating body and an outer case by sealing the inside and outside using a noncontact seal during rotation of the rotating body, in an airtight manner. A rotation coupling unit is provided at the upper end of a centrifugal cylinder, and even when the centrifugal cylinder is deformed during use causing an internal fluid to leak through a fitting portion of a bottom member to the centrifugal cylinder, the fluid leaks in the hermetically sealed space so that the driving system or the like is not contaminated.

A blood component separation device includes a centrifuge bowl for separating a blood component from blood, a plasma bag for storing a plasma component, a platelet intermediate bag for storing high-concentration platelet liquid having high-concentration of platelets, and a temporary storage bag (also used as a buffy coat bag) for storing low-concentration platelet liquid having low-concentration of platelets. The blood component separation device performs control, from the second cycle onward, to mix the low-concentration platelet liquid stored in the temporary storage bag in the immediately preceding cycle with whole blood to supply the mixed liquid to the centrifuge bowl. An amount of high-concentration platelet liquid to be collected in the platelet intermediate bag in the first cycle is set to be smallest among all cycles, and an amount of high-concentration platelet liquid to be collected in a last cycle is set to be greatest among all the cycles.

The disclosure relates to a sealing tool for a packaging machine which comprises a tool lower part with at least one centrifugal separator for separating a particle-laden gas flow. The disclosure further relates to a method for separating a particle-laden gas flow at a sealing tool of a packaging machine, where the particle-laden gas flow is separated by way of a centrifugal separator provided at a tool lower part of the sealing tool.
