PROBLEM TO BE SOLVED: To provide a method for recovering the dried rubber in pulse combustion in which the dried rubber can efficiently be recovered by instantaneously drying a rubber composition solution and an apparatus for recovering the dried rubber. SOLUTION: In a wire net filtration means 13 in the apparatus for recovering the dried rubber, a filtering net 14 formed in truncated cone shape is rotatably attached to the vicinity of the outlet part 7a of a drying chamber hopper 7 as shown in figures 2 to 4 and large-size circular gears 15a and 15b are attached to upper and lower parts of the filtering net 14 and driving gears 16a and 16b connected to a driving motor, etc., not shown in the figure are engaged with the outside of the circular gears 15a and 15b and the filtering net 14 is rotated at a prescribed rate by driving the filtering net 14 from the outside. A fixed scraping blade 17 for scraping rubber particles Wx attached to the inside of the filtering net 14 is attached to several places on the inside of the filtering net 14 formed in truncated cone shape and a clearance having about 0.1 to 1 mm size is provided between the tip of the scraping blade 17 and the surface of the filtering net 14 in the drying chamber hopper 7 so that the rubber particles Wx are efficiently scraped off.
