Overview
- Pulse type and condition determine the treatment and milling sequence.
- Allow space for conditioning, drying, intermediate storage and return streams.
- Agree whole dhal, brokens and losses as separate outputs when assessing recovery.
A dal mill removes the husk and splits pulses into dhal. The process varies with the pulse, grain condition and intended product. Conditioning and return streams need as much attention in the layout as the milling machines.
Confirm the process for each pulse
A traditional line may use cleaning, grading, pitting, oil or water treatment, drying, dehusking, splitting and separation. Some material needs another pass. Confirm the selected process with the supplier; there is no single treatment recipe for every pulse.
Make room for the full batch cycle
- Schedule conditioning and drying around the mill capacity and local conditions.
- Separate finished product, brokens and material returning for treatment.
- Include intermediate storage and cleanout access.
- Check conveying routes for unwanted mixing and product damage.
- Coordinate aspiration, dust controls and safe maintenance access.
Review the layout against the production plan
Spetia can coordinate the process layout, structure and services for the agreed product range. Bring the supplier flow sheet and batch schedule to the plant engineering review. Record which performance claims need trials or commissioning evidence.
