PROBLEM TO BE SOLVED: To provide a sieving device that can effectively solve clogging of a sieving net while it performs sieving of raw materials continuously. SOLUTION: A sieving space 11 which is formed in a device housing 10 is divided into an upper space of the sieving device 16 and a lower space of the sieving device 17. On a cover 20 that closes the upper face of the upper space of the sieving device 16, a material injection port 23 is provided thereon, while under this material injection port 23, a material dispersion plate 25 is provided. To the lower space of the sieving device 17, a product outlet port 30 is installed and a suction duct 8 is connected thereto. Similarly, in the lower space of the sieving device 17, a nozzle 33 is positioned which blows air up to a sieving net 15 while it is rotating under the sieving net 15. In one side of the upper space of the sieving device 16, a remaining particle exhaust port 40 is provided. To this port, a door 40 is provided so that an open/close condition can be selected. Meanwhile, to the remaining particle exhaust port 40, a height variable gate plate 46 is arranged.
