Gain-in-weight batching: Choosing system components for maximum accuracy

The scale isn't the only contributor to your gain-in-weight batching system's batching accuracy. The feeders, and the control system that governs them, also make major contributions to batching accuracy by controlling the feed rate during the batch and stopping the ingredient flow when the batch setpoint is reached. This article details an example application to explain how batching time, batch container and feeder size, batching controls, dust collection, and batch container emptying can affect a gain-in-weight batching system's accuracy. Calculations are included to help you choose system components based on your batching requirements.

Selecting the right components for your batching system is crucial to achieving your desired batching accuracy. In this article, we'll focus on how components in a gain-in-weight [also called add-weigh] batching system affect the system's accuracy. Unlike a loss-in-weight batching system, which controls batching by sensing weight loss in a gravimetric feeder, in a gain-inweight system each ingredient is dispensed by a volumetric feeder into a batch container on a scale [also called a weigh hopper], and the batching process is controlled by sensing the weight added to the batch container.
