Powder Flowability — Characterization for Paprika¶
Definition¶
Flowability describes how easily a powder moves under gravity or applied forces. For paprika powder, poor flowability leads to bridging in hoppers, inconsistent fill weights, and dusting during packaging.
Measurement¶
| Parameter | Formula | Good Flow | Fair Flow | Poor Flow |
|---|---|---|---|---|
| Carr Index (CI) | (T−L)/T × 100 | < 15 | 15–25 | > 25 |
| Hausner Ratio (HR) | T/L | < 1.15 | 1.15–1.25 | > 1.25 |
Where L = loose bulk density, T = tapped density.
Typical Values for Paprika¶
| Particle Size | CI | HR | Flow Character |
|---|---|---|---|
| 20 mesh coarse | 12–18 | 1.12–1.22 | Good |
| 40 mesh standard | 18–24 | 1.20–1.30 | Fair |
| 60+ mesh fine | 25–35 | 1.30–1.50 | Poor — bridging risk |
