Executive Summary for TKP Grinders & Sizing Plants
Tamarind Kernel Powder (TKP) is one of India's most important indigenous industrial polysaccharide polymers. Formulators in the textile sizing, corrugated cardboard, and plywood glue sectors rely on TKP for its high viscosity and cost-effectiveness compared to synthetic corn starches.
However, the commercial recovery ratio and slurry viscosity of the final powder depend entirely on the physical hardness, dryness, and purity of the raw seed (Puliyamuthu).
1. Critical Milling Specifications
| Technical Metric | Target Industrial Specification | Milling Relevance |
|---|---|---|
| Moisture Content | Below 10.0% | Ensures brittle hull fracture during roasting & decortication |
| Foreign Impurities | Under 1.0% (Screened for stones) | Protects commercial hammer mills & pulverizers from tooth damage |
| Insect / Weevil Infestation | Nil (<0.5% visible bores) | Preserves seed endosperm protein and xyloglucan starch yield |
| Kernel Recovery Ratio | 68% – 72% dehulled white kernel | Direct yield determinant for finished TKP flour |
2. Decortication & Roasting Behavior
High-grade Ramanathapuram tamarind seeds feature thick, vitreous outer hulls. When subjected to commercial gas or wood-fired roasting roasters, the hull pops cleanly away from the white cotyledon kernel with minimal scorching, yielding a pale, high-viscosity powder preferred by textile export printers.
