PROBLEM TO BE SOLVED: To provide a processing pipe installing structure capable of simply and positively installing and decomposing the processing pipes at a dryer having annular processing pipes laterally installed in a horizontal direction. ! SOLUTION: A dryer 1 is an air-flow type continuous dryer and includes a granulation input part 11, a drying and processing part 12 and a product discharging part 13. The drying and processing part 12 has a looped pipe 25 where stainless steel pipes are arranged in a helical manner. The looped pipe 25 is made by connecting semi-circular loop pipe units 31 together by connectors 32a, 32b of double seal structure and the upper and lower loop pipes 25 are connected by a joint part 40. The joint part 40 comprises a fitting joint 43 and a guide joint 44. The fitting joint 43 is made by fitting a convex-type joint 43a and a concave-type joint 43b to each other in convexoconcave fitted manner in a vertical direction. The guide joint 44 comprises a convex joint 44a and a con |
