This unit operation converts bulk material into discrete entities. It can be useful in modeling certain product formulation and packaging operations (e.g., formation of chocolate bars from molten chocolate). The user specifies the properties of the discrete entity (name and bulk amount) and the program calculates the operating discrete throughput (in entities/min).
● Bulk to Discrete Generic Box Procedure
If the Equipment Size option is in Design Mode and the operating throughput exceeds the Maximum Throughput, then, the program assumes multiple, identical units operating in parallel with an operating throughput of less than the maximum. If the equipment size option is in Rating Mode and the operating throughput exceeds the rated throughput of the step (which is equal to the rated throughput of each unit times the number of units), a warning message is displayed advising the user to increase the number of units or reduce the operating throughput.
To account for electricity consumption, the user can either specify the power demand (in kW) or the specific power requirement (in kW/parts-min). In the second case, the specific power requirement times the operating throughput yields the power consumption.
