Optimal raw material exploitation depends on accurate and efficient filling systems. Knowing the advantages of the different filling technologies allows manufacturers to choose the solution that fills containers quickly, but with minimal giveaway.

Reducing waste and improving yield of crops or bulk food materials is a key issue in production. Food producers are looking at different areas in which savings by reducing waste can be realized. One important aspect is losses of raw materials.
Reduce Giveaway in Bulk Foods
Handling bulk materials often ends with a filling step. Materials are transferred within the production facility and finally filled into containers of different sizes, such as drums, intermediate bulk containers or big bags. However, many organizations fear of falling foul of the weights-and-measures approval, and this leads to overfilling.
Volumetric vs. Gravimetric Filling
Which system is the best when filling bulk materials? Commonly, filling machines use either volumetric or gravimetric methods to control fill quantity. Volumetric fillers, such as flow meters, can suffer from a number of problems with changes in material properties, such as viscosity or density. In comparison, filling by gravimetric methods provides advantages that clearly help reduce the risk of overfilling, including:
- Better accuracy and operation within a smaller tolerance band and
- Traceably supported net-content legislation.
