Discrete Pass-Through/Bulk Separation: Oper. Conds Tab

Variable Definitions, Ranges and Default Values

The following table shows a brief description of the variables appearing in this tab. The table also displays their default values and their generally acceptable range:

Variable	Default Value	Range

● Entering Entity Description The description of the discrete entities that are fed into the equipment unit.	<Entity Name Unknown>	Any Text
○ Exiting Entity Description The description of the discrete entities that are transferred out of the equipment unit.	<Discrete Entity>	Any Text
● Operating Throughput per Unit (entities/h) The feed rate of discrete entities per equipment unit.	0.0	Positive
○ Removal % The percent mass of the corresponding component that is split to the bulk material output stream.	0.0	[0,100]
○ Setup Time The amount of time (per cycle) spent before each operation is carried in preparation for the actual execution of the operation. It may involve actions like cleaning, vacuuming, setting up of equipment, etc. which the user opted not to model explicitly.	0.0	Positive
◙ Process Time The actual duration of the operation (per cycle). It can be either set by user or set by a master-slave relationship.	0.0	Positive
○ Ignore Labor? Check this box to ignore labor for this operation. This option is used only if the process time is set by a master-slave relationship.	Yes	Yes/No
○ Power Type Indicates the power type that is used by the operation. Click on the list box to bring up a list of available power types in order to select one.	<Std Power>	Any Power Type
◙ Specific Power (kW/(Entity/h)) The power consumed for the operation per feed rate of discrete entities.	0.0	Positive
◙ Total Power (kW) The total power consumed for the operation (per cycle).	0.0	Positive
◙ Power Per Unit (kW) The power consumed for the operation per equipment unit.	0.0	Positive
○ Power Dissipation to Heat (%) The percentage of total power consumed for this operation that turns into heat, thereby raising the temperature of the material contained in the equipment.	0.0	[0,100]

Symbol Key: ○ User-specified value (always input); ● Calculated value (always output); ◙ Sometimes input, sometimes output

Specification Choices / Comments

The following list describes the available specification choices in this tab; for more details on how these are implemented, see Discrete Pass-Through/Bulk Separation: Modeling Calculations.

•Entity Description...

The description of the Entering Entity to the equipment is displayed. You may also specify a description for the Exiting Entity from the equipment that results from separation of bulk material.

•Duration Options...

You can set the process time (the sweeping time) or match the duration of this operation to the duration of another operation by introducing a master-slave relationship between the two operations. If you introduce a master-slave relationship, the program will match the setup time, the process time and the turnaround time of this operation (the ‘slave’) with the corresponding times of the reference operation (the ‘master’ operation). For more details on how to setup a master-slave relationship, see The Scheduling Tab.
