Claim 3:
4. The control device according to claim 1, wherein
the granular material supply system further includes a carrier line flow rate control valve provided in the carrier line and a cutout line flow rate control valve provided in the cutout line,
the density control unit controls an opening degree of the cutout line flow rate control valve so that a measurement value of the density of the granular material on the downstream side of the junction coincides with the set value, and
the flow rate control unit controls an opening degree of the carrier line flow rate control valve so that a supply flow rate to the carrier destination of the granular material estimated based on a measurement value of a flow rate of a carrier gas flowing on the downstream side of the junction in the carrier line and a set value of the density coincides with the command value.
