ABSTRACT:
An agent transport unit for transporting an agent from a first container to a second container includes a transport route and a pump. The transport route connects the first container and second container, and includes at least one of a first route, a second route, and a third route. The first route extends in a substantially horizontal direction, the second route extends in a substantially vertical direction, and the third route extends in a substantially inclined direction with a repose angle equal to or less than that of the agent. The pump supplies a gas flow into the transport route to transport the agent in the transport route.
