Batch Filler Icon
Batch Filler nodes represent storage that operates in repeating filling and emptying cycles. Unlike standard buffers, which continuously accept and release material, a batch filler alternates between collecting material and discharging it. It fills until reaching its defined capacity, then switches to emptying mode and drains completely before beginning the next fill cycle.
This behavior makes batch fillers useful for modeling processes such as tanks, hoppers, totes, or containers that must be filled before downstream processing can begin. While the batch filler is filling, downstream flow is paused. Once full, material is released until the batch is emptied, after which the cycle repeats.
A batch filler behaves like a buffer with structured batching logic. Upstream constraints determine how quickly the filler reaches capacity, while downstream operations determine how quickly it empties. Because the node must complete each fill-and-drain cycle before starting the next, batch fillers naturally introduce periodic flow patterns into the system.
When building a model, batch filler nodes should be used wherever material is accumulated into discrete batches rather than flowing continuously. As with other node types, it’s best to start with simple capacities and observe behavior in Replay, then refine parameters as needed to reflect real operating cycles.
