Hygienic Packaging for Food Powders & Granules

Dust-free, hygienic filling for flour, milk powder, starch and other fine food powders, built to keep product contained and product lines clean.

Fine food powders bring a different challenge than granular grain: dust control, hygiene, and consistent dosing of a material that can bridge or cake in a hopper. Flour, milk powder, starch, and similar products need enclosed transfer, anti-caking-aware feed mechanisms, and a sealed bag neck that keeps both product and airborne dust where they belong. Ecronic’s flow-control and packing equipment is built around exactly that combination.

Primary Materials
Flour, milk powder, starch, fine food granules
Typical Bag Format

1–25 kg bags, dust-sealed valve or open-mouth

Key Requirement

Dust containment and hygienic, anti-caking dosing

Why It Works for Food Powders & Granules

Enclosed Powder Transfer

Fully enclosed hoppers and chutes prevent airborne dust from escaping into the production area.

Anti-Bridging Feed Design

Agitated feed mechanisms keep fine powders flowing evenly instead of bridging or clumping in the hopper.

Weightlessness Precision Dosing

Flow-based metering delivers accurate small-increment dosing for fine, low-density powders.

Hygienic Contact Surfaces

Product-contact components are finished for easy cleandown between batches and product changeovers.

Dust-Sealed Bag Necks

Filling heads seal tightly at the bag neck to contain fine dust during transfer and stitching.

Small to Mid-Format Packs

Configured for the 1–25 kg range typical of retail and food-service powder packaging.
