    It should be derived during the PQ of the equipment using placebo product with different bulk density.
    Take atleast 3 runs on your coating pan using placebo product (tablets or granules) and check the equipment behaviour.
    Durign selection of placebo, consider the product with high density (sugar) and low density (starch)

    the capacity of coater determine by knowing brim volume (water volume) of pan and multiplying the Bulk density of tablets 0.65 g/ml e,g,
    for max capacity
    500 ltr. (Brim Volume) X 0.65 g/ml = 325 Kg
    For minimum capacity

    60 % of Brim Volume X 0.65g/ml = Mimimum batch size
    However it my vary depending up tablet size and shape.
