Ground Coffee
Coffee Grounds · Roasted and Ground Coffee · Espresso Grind · Filter Grind
Ground coffee is the processed and milled form of roasted coffee beans. It is a fine, aromatic, and lightweight material that varies in particle size depending on the grind level. Ground coffee is hygroscopic and can absorb moisture rapidly, leading to clumping, spoilage, and flavor degradation. It also generates fine dust that can pose explosion risks in enclosed conveying systems. KWS designs conveying systems that provide gentle handling, dust control, and sanitation for food-grade environments.

Material Characteristics
| Property | Value / Description |
|---|---|
| Common Forms | Fine To Coarse Powder Depending On Grind Type |
| Bulk Density | 20–30 lb/ft³ (varies with roast level and particle size) |
| Flow Behavior | Cohesive and compressible; may bridge or cake under humidity |
| Abrasiveness | Low gentle on equipment surfaces |
| Corrosiveness | Not Corrosive but can retain oils and moisture |
| Dust Potential | High fine dust is combustible and aromatic particles require containment |
Handling Challenges
- Caking and clumping due to moisture absorption
- Dust explosion risk from fine organic particles
- Degradation of flavor and aroma from heat or oxidation
- Residue buildup in conveyors from coffee oils
- Strict hygiene requirements in food-grade processing
Summary
Ground coffee requires bulk handling systems designed for fine, aromatic, and moisture-sensitive powders. KWS Manufacturing provides engineered food-grade conveying systems—including screw conveyors, drag conveyors, and feeders—that maintain product integrity, prevent dust emissions, and simplify sanitation.
With extensive experience handling food ingredients and organic powders, KWS ensures efficient, hygienic, and reliable operation for ground coffee handling systems.
