10. A method for making freeze-dried fruit powder, applicable to the production device described in any one of the above claims 1-9, characterized in that, The specific steps are as follows: S1. Control the motor (58) to work. The work of the motor (58) drives the first rotating shaft (27) to rotate. The rotation of the first rotating shaft (27) drives the rotating rod (6) and the reciprocating lead screw (32) to rotate. The rotation of the rotating rod (6) causes the spiral blade (7) to rotate. Under the action of the moving block (34), the toothed plate (40), and the convex rod (13), the rotation of the reciprocating lead screw (32) causes the two first grinding blocks (12) to move back and forth; S2. Place the freeze-dried fruit in the feeding hopper (15). The freeze-dried fruit falls into the crushing box (2). At this time, since the spiral blade (7) rotates, the freeze-dried fruit is conveyed to the lower right, and a crushing rod (8) spirally distributed is designed on the spiral blade (7) to pre-crush the freeze-dried fruit during conveyance. S3. The pre-crushed freeze-dried fruit enters the housing (10), and then passes through the gap between the two first grinding blocks (12). Since the two first grinding blocks (12) move back and forth, the freeze-dried fruit is ground into powder when passing through.
