PROBLEM TO BE SOLVED: To collect surface deposit with high efficiency by peeling off surface deposits on an object to be treated by shot blasting inside a sealed processing chamber, and gaseously-carrying powder and grain generated by peeling off to the outside of the processing chamber. SOLUTION: A shot blast device 4 is provided with an endless rubber belt 9 which is wound into an L shape inside a peeling-off and processing chamber 8 for storing objects 2 to be processed and usually rotates in the direction of an arrowhead A. At the upper part of the peeling-off and processing chamber 8, there is an injecting peeling means 11 which injects a projection material 10 to the object 2 to be processed at a high speed. The injecting peeling means 11 injects a plurality of injection materials 10 downwards at a high speed by means of pneumatic pressure to peel off and break deposits with high efficiency by an impact at the time of collision with the object 2 to be processed. A dust collector 14 takes out powder and grain 3 in the peeling-off and processing chamber 8 to the outside of the peeling-off and processing chamber 8 through an air duct 13 by means of suction with a vacuum pump and delivers the powder and grain 3 to a separating means 15.
