<P>PROBLEM TO BE SOLVED: To provide a sieve frame for a sifter capable of reliably preventing coarse powder and foreign matter from being mixed into a product side in the conventional sieve frame. <P>SOLUTION: Joint surfaces of a mesh frame and an outer frame which internally fit to each other are machined so that the surfaces are inclined to each other, thereby, a gap is not produced between the both to secure tight adhesion and mixing of coarse powder from the upper part of the mesh surface and stagnation of the powder can be reliably prevented. <P>COPYRIGHT: (C)2013,JPO&INPIT |
