PROBLEM TO BE SOLVED: To provide a multipoint time-sharing temperature control system for heating or drying granule which can contrive the cost down, is small in installation space, and can automatically control the temperature of many points of heat treatment stations even if they are operated each independently or are interlocked mutually. SOLUTION: A plurality of heat treatment stations ST are provided with heat treatment means H and temperature detection means K. One unit of temperature controller 1 is equipped with a temperature controller 2 which can allow the user to set the temperature objective value of the heat treatment station ST, an output control unit 3 which is connected to each of a heating means H, a temperature detection means K through an independent line S and a control line C, and an I/O unit 4. The temperature controller 1 takes the temperature measurement data from the temperature detection means K of the heat treatment station SR into the I/O unit 4 by time sharing, and controls a corresponding heating means H while comparing it with each temperature objective value with the temperature controller 2.
