Prepared cavities are placed in the product mounts and transported to the filling station. Minimum quantities of powder are filled at several filling stations within a specific clocking sequence. Dosing units with multiple, synchronized fill positions are used for higher outputs.
Some dry powder inhalers include a powder reservoir for a pre-defined number of dosages. Generally, the defined quantity of active ingredients is filled using an auger filler. Several filling spaces can be integrated to increase the output.
A gravimetric scale calculates the weight during the filling process. Once filling approaches the target weight, the output quantity is reduced and the filling process is continued via fine dosing until the pre-defined target weight is reached exactly. Fill-to-weight allows quick and precise dosing.
