Sangli district produces about 70% of India’s raisins (Wikipedia: Sangli raisins), and Ratnagiri–Sindhudurg have about 800 cashew-processing units (NCAER, 2021). Both industries sell on appearance — and that is exactly what an optical sorter controls.
Bühler SPARK Pro and SPARK Pro+ for raisins and cashews
The Bühler SPARK series is our first recommendation for raisin and cashew processors. Essar Pneumatics & Equipment has completed trials of SPARK on raisins and cashews with successful results.
Come and experience the trial, then decide. Bring a lot of your own raisins or cashew kernels, watch SPARK sort it, and compare the accepted and rejected product yourself.
Why SPARK suits raisin and cashew units
- Multi-commodity — one machine works like a multi-purpose tractor: raisins in season, cashews, and other commodities such as pulses, grains and spices the rest of the year, so it does not sit idle.
- Simple operation — “Hue Saturation Value” set-up is five times faster than previous models and does not depend on highly skilled operators.
- HD full-colour cameras with full-spectrum LED lighting (2x more light) to pick out colour defects.
- DynamoAI sorting engine with size sorting for undersize and oversize pieces.
- Zero-spillage concept to avoid product losses.
- Scales with your unit — modules from 1 to 10 chutes.
- SPARK remote control — check and control the sorter’s performance from anywhere.
SPARK Pro or SPARK Pro+?
Both models share the DynamoAI engine, 15″ touch screen, full-colour HD camera, high-frequency sniper valves, size sorting, full-spectrum LED lighting and remote control. SPARK Pro+ adds an HD NIR (infrared) imaging system, which gives it a higher rating for foreign material such as glass, wood, metal, textile and plastics. After the trial on your sample, we recommend the model that fits your product and budget.
