This operation handles batch-wise storage of discrete entities in a bin or a drum. It is available for use in the Discrete Batch Storage in Bin / Drum procedures. It can be used to simulate the storage of pharmaceutical tablets at different stages of processing.

● Batch Storage in a Drum (Discrete) Procedure
● Batch Storage in a Tote (Discrete) Procedure
In terms of sizing, the bulk volume of the discrete material to be stored is first calculated based on the option selected by the user. The user defines in the volumes tab whether the bulk volume is calculated based on a user-defined bulk density or on a user-defined volume per entity.
In Design Mode of calculation, the user specifies the working to vessel volume ratio (through the Volumes tab) and the program sets the working volume (Vw) equal to the bulk volume of material that is processed per cycle. The number of cycles per batch is specified through the Scheduling tab. The vessel volume (V) is calculated using the following equation:

If the calculated volume exceeds its maximum possible value (specified through the Equipment tab), the program assumes multiple (identical) units operating in parallel with a total vessel volume equal to the calculated.
In Rating Mode, the user specifies the vessel volume and the number of units. The program calculates the working to vessel volume ratio and warns the user if its value is outside of its minimum and maximum limits.
