1. A rotary processing system, comprising:
a particulate additive;
a drum including a feeding unit for feeding a processing object including soil and the particulate additive on one side of the drum and a discharger for discharging the processing object on an other side of the drum;
a processor that is connected to a rotation axis member, rotates about a rotation axis of the rotation axis member, and mixes the soil and the particulate additive in the drum; and
a suppressor that suppresses a release of particles of the particulate additive in the drum through the feeding unit caused by rotation of the processor, wherein the suppressor extends in a radial direction away from the rotation axis towards a radially-outer end of the suppressor that is spaced apart from an inner peripheral wall of the drum, and a length of the suppressor in the radial direction is shorter than a length of the processor in the radial direction.
