Gain-In-Weight Batching is a cost effective method of weighing since it requires only one or two scale systems for a number of ingredients.

A Batch Weighing System is similar in design to a continuous Loss-In-Weight Feeder. Batch applications do not, however, require that material be continuously fed with high-feed accuracy.


Vibra Screw equips its continuous and batch weigh feeders with state-of-the-art control packages. All controllers incorporate user-friendly, menu-driven software. Membrane keypads and easy-to-read displays support a revolutionary concept of deciphering actual weight from plant vibration and electrical noise.
