Gravimetric Feeding in Food Production

Answer in brief

Food lines feed everything from flour by the tonne to flavours by the gram, and one feeder rarely covers both.

The accuracy that matters is at the smallest inclusion, and that is where an oversized feeder fails quietly.

Size the feeder for the smallest rate it must hold.
Choose the discharge device for the powder, not for the catalogue.
Design the feeder to be cleaned between recipes.

The problem

Minor ingredients at low inclusion determine taste, colour and label compliance, and they are usually the most cohesive powders in the recipe.

Fragile products are damaged by the wrong discharge device.

Desired outcome

A feeder that holds the set rate across the required turndown, with an inlet condition it can cope with and an installation that does not corrupt the weight signal.

Process approach

Twin screw feeders handle cohesive powders, single screws suit free-flowing material and vibratory trays protect fragile products.

Hygienic construction with quick-release hoppers and screws makes recipe changeover realistic rather than theoretical.

Refill from a bulk bag station or a conveying line has to be smooth, because a surge in refill becomes an error in rate.

Discharge device matched to the powder behavior.
Tool-free dismantling for cleaning between recipes.
Controlled refill that does not disturb the weighing.

Selection factors

Smallest inclusion rate and the tolerance on it.
Flow behavior of each ingredient.
Allergen matrix and the cleaning standard.
Product fragility where granules or flakes are fed.
Dust explosion characteristics of the powder.

Common failure modes

Feeder sized for the largest ingredient and used for the smallest
Cohesive powder bridging above the screw
Residue in the feeder after a recipe change
Refill surge appearing as a rate deviation
