IEDCO Porta-Batch System

Portable batching from bulk containers

Purpose: Porta-Batch replaces manual scooping between containers with a mobile conveying and weighing system.

IEDCO documents a package containing the vacuum conveyor, rotary valve, controls, integrated scale and a roller track for loading and removing small receiving containers.

How batch accuracy is established

The scale measures the receiving container and its contents. The controls stop or trim material delivery as the target is approached.

In-flight material: powder between the shutoff point and the receiving container keeps falling after the stop command. The controller can compensate only when that quantity is repeatable. A leaking rotary valve, variable aeration or material retained in the receiver turns the final trim into guesswork.

Coarse transfer should deliver most of the batch quickly. The final approach may use pulsed feeding, a lower valve speed or another controlled trim mode, and that method has to stay stable across bulk-density variation and the full target-weight range.

Actual accuracy therefore rests on scale resolution, vibration isolation, in-flight material, valve behavior, line cleanout and the powder's flow pattern. A factory or site test should cover several target masses and container changes, not one convenient batch.

Integration and operation

The source may be a drum, Gaylord box or another bulk container. The receiver, discharge valve and roller track must suit the container opening and the dust-control arrangement.

Moving the system between areas introduces recipe, destination and cleaning-control questions. Operators need a clear way to confirm the material, the target, the container and the released state of the equipment.

Data to verify before selection

• Batch range, tolerance and scale verification method.
• Bulk density, flowability, dustiness and product carryover.
• Container sizes, closure method and roller-track load.
• Coarse and fine feed strategy near the setpoint.
• Cleaning and line-clearance procedure between materials.
• Controls records, recipe permissions and exception handling.

Portable batching can remove a lot of awkward manual work. It also moves the control boundary with the machine, so utilities and data connections have to be as deliberate as the wheels.

Verification and changeover

Qualification should challenge minimum and maximum batches, repeated container taring, power interruption and an aborted transfer. Reconcile the source loss, receiver inventory and packaged mass when material value or traceability demands it.

Cleaning is part of the batching method. Identify product traps in the receiver, valve, flexible hose and frame, then set inspection and release criteria before the next material runs.

Electronic records should preserve setpoint, actual net weight, lot identity, operator actions and alarms without allowing an unrecorded manual top-up.
