And in the material compartment operation of step 4120, the plurality of second cells 324a are moved such that the plurality of second cells 324a take turns to receive the second material S2. In detail, the user can drive the driving module 500a to drive the metering disk 320a to rotate, and the second inlet 3241a of the second measuring cell 324a can alternately correspond to the second opening 250a to receive the second material S2.

In addition, in the material removal operation of step 430, the second quantity grid 324a of the predetermined number is moved to make the second quantity grid 324a of the reserved quantity corresponding to a second discharge port 332a, and the second quantity grid 324a of the reservation quantity is taken out. The second material S2 in the middle is metered. In this step 430, the driving module 500a is driven to rotate the metering disk 320a, and the second outlet 3242a of the second measuring cell 324a can be corresponding to the second discharging port 332a on the carrier disk 330a, so that the second material S2 is made. It falls out from the second discharge port 332a.
