1. A bioprocessing system comprising:
a main line for conduction of a main flow of a liquid medium,
a main flow pump for generation of the main flow, and
a system part connected to the main line,
wherein the bioprocessing system further comprises:
a powder transfer system for metered delivery, in particular dust-free metered delivery, of an additive, and
a feed line which is connected to the powder transfer system and which opens into the main line at a feed point and which comprises a return flow preventer for prevention of a return flow of liquid medium, wherein the powder transfer system feeds the additive into the feed line in powder form and drives it toward the feed point by a pressurized transport gas and wherein at least some of the additive is input into the liquid medium within the main line downstream of the feed point before the liquid medium enriched with the additive passes through or reaches the system part connected to the main line;
wherein the powder transfer system comprises a transport gas source for the pressurized transport gas and wherein the powder transfer system feeds the additive into the feed line by the pressurized transport gas.
