A classifying rotor comprising:

• a rotatable frame body having an opening portion on an outer peripheral portion and having an ejection port for ejecting a fluid having flowed into an inside through the opening portion to an outside, the rotatable frame body comprising two circular plates disposed coaxially with each other and vertically separated from each other;
• a plurality of classifying blades disposed at a desired interval in a circumferential direction on an outer peripheral side part in the frame body and between the two circular plates;
• and
• a plurality of rectifying blades disposed on an inner side part from the classifying blade in the frame body at a desired interval in the circumferential direction and between the two circular plates;
• wherein the ejection port is located at a center part of the rotatable frame body, and wherein the plurality of rectifying blades are located between the election port and the plurality of classifying blades.
