The invention relates to the technical field of 
food processing, in particular to an efficient 
food material blender. The blender comprises a blending 
barrel, a lifting fork, a gear change hand lever,a blending shaft, blending blades and a lifting hand wheel; the lifting hand wheel comprises a driving rod, a driving disc, a driving hand lever, operation through holes, cambered protrusions and cambered ring slots; the gear change hand lever comprises a rotating block, a rotating rod, a hemispherical boss, an anti-skid protrusive strip and a mounting piece, the mounting piece is formed by sequentially connecting a locking protrusive block, a conical ring table and a cylindrical rod, locating protrusive strips are arranged on the side portions of the cylindrical rod, a mounting 
blind hole isformed in the side portion of the rotating block, a locking ring slot and a conical ring slot are formed in the inlet of the mounting 
blind hole, and locating grooves are formed in the inner wall ofthe mounting 
blind hole. The blender has the advantages that the structure is simple, the operation 
modes of the lifting hand wheel are diversified, and the 
assembly efficiency of the gear change handlever is high.
