in the second step, mother liquor is added into a mother liquor tank (14) through a feed inlet (23), a plurality of separation holes (20) can intercept caking in the mother liquor, simultaneously, a motor (61) is started, the motor (61) drives a rotating shaft (62) to rotate, a plurality of stirring rods (63) are driven to rotate when the rotating shaft (62) rotates, a plurality of fixing rods (64) are driven to rotate when the stirring rods (63) rotate, the mother liquor is stirred and scattered through the stirring rods (63) and the fixing rods (64), caking in the mother liquor is crushed through a plurality of rotating tooth blocks (65), the mother liquor is further scattered, a plurality of scraping plates (66) are synchronously driven to rotate when the stirring rods (63) rotate, the caking adhered on the inner wall of the mother liquor tank (14) is scraped, resource waste is prevented, later cleaning is also facilitated, a plurality of mounting rods (71) are driven to rotate when the mounting rods (71) rotate, a plurality of fixing rods (75) are driven to move, a plurality of dredging rods (75) are driven to move with a corresponding separation hole (20) to a plurality of springs (74), a dredging hole (20) is correspondingly inserted into the separation hole (20), the dredging hole is correspondingly separated through a plurality of springs (20), and the dredging hole (20) is correspondingly separated through the dredging hole (20), prevent that the caking in the separation hole (20) from causing the jam phenomenon, guarantee that mother liquor smoothly passes through separation board (19), still can drive first clearance board (83) and second clearance board (84) through first connecting plate and second connecting rod (82) when pivot (62) rotate, clear up the caking on mother liquor jar (14) inner wall and the diapire, further prevent the wasting of resources, finally mother liquor is carried in feeding pump (18) through output tube (16), feeding pump (18) is carried atomizer (12) again through connecting pipe (13), spray mother liquor in drying tower (1) with the steam contact through atomizer (12), accomplish the drying;

and thirdly, conveying the used hot gas to the next procedure through an air outlet (11), opening a discharge valve, and discharging the powder product in the drying tower (1) through a discharge outlet (9).
