  "claims": [
    "1. A drying system comprising: a transfer conveyor for transporting particles having a width with a center portion and a direction along the width thereof; a particle dispersing device including a rotary member provided at one side of the transfer conveyor and having a rotation center, a drive part for rotating the rotary member and a particle supply part mounted on the rotary member having particles stored therein; and a heating part for drying the particles on the transfer conveyor in a transfer process, wherein the heating part comprises a heat exchanger and a blast fan, and is provided such that air discharged from the blast fan is supplied to the transfer conveyor after passing through the heat exchanger, a control part for controlling the transfer conveyor and the drive part, wherein upon supplying the particles to the transfer conveyor, the control part controls so that the particle supply part rotates along an arc about the rotation center of the rotary member in a predetermined direction, wherein when the particle supply part is rotated, the control part stops the transfer conveyor, and wherein the control part controls so that the particle supply part rotationally reciprocates in different directions within a predetermined angle range about the rotation center.",
    "2. The drying system according to claim 1, wherein the heat exchanger is provided such that air passing through the heat exchanger can be distributed across the width direction of the transfer conveyor.",
    "3. The drying system according to claim 1, wherein the heat exchanger is disposed below the transfer conveyor.",
    "4. The drying system according to claim 3, wherein the heat exchanger is elongated along the width direction so as to correspond to the width of the transfer conveyor.",
    "5. The drying system according to claim 1, wherein if the rotation of the particle supply part is completed, the control part operates the transfer conveyor such that the loaded particles are transported.",
    "6. The drying system according to claim 1, wherein the particle supply part comprises a belt conveyor.",
    "7. The drying system according to claim 1, wherein the control part controls so that along the width direction of the transfer conveyor, the particles are loaded thicker on both side edges than the center portion."

  "description_excerpt": "The present application is a National Phase entry pursuant to 35 U.S.C. § 371 of International Application No. PCT/KR2017/015181 filed Dec. 21, 2017, and claims priority to and the benefit of Korean Patent Application No. 10-2016-0178853 filed on Dec. 26, 2016, the disclosures of which are incorporated herein by reference in their entirety.\n\nThe present invention relates to a drying system.\n\nA drying process of a particle-based polymer performed through a drying system is carried out through hot air or the like after uniformly dispersing particles on a transfer conveyor. At this time, a spreading oscillator is used to disperse and load the particles evenly on the transfer conveyor along the width direction of the conveyor.\n\nFIGS. 1 and 2 are schematic diagrams for explaining one operating state of a particle dispersing device (spreading oscillator) (10). The oscillator (10) comprises a rotating shaft (11) and a particle supply part (12) mounted on the rotating shaft (11). At this time, the particle supply part (12) is provided to reciprocate within a predetermined angular range about the rotating shaft (11). In such a structure, a method is used, in which the particle supply part (12) rotationally reciprocates, drawing an arc on the basis of the rotating shaft (11), to spread particles (P) to be dried on a belt (21) of a transfer conveyor (20).\n\nFurthermore, referring to FIG.",
