An optical (colour) sorter looks at every grain with cameras and blows out the bad ones with a precise jet of air — like a quality inspector who checks thousands of grains per second and never gets tired. Essar Pneumatics & Equipment supplies the full Bühler range for processors in our Maharashtra and Goa districts.
Bühler SPARK Pro+ — simple and robust
Bühler’s entry range, designed for processors who want Bühler quality at an accessible price (SPARK Pro+ brochure, 06/24).
- 1 to 10 chute modules; single-channel throughput 1.5–2.0 t/h depending on application
- HD full-colour cameras plus HD infrared (NIR) camera on the Pro+ — detects defects down to 0.0025 mm²
- Full-spectrum LED lighting and DynamoAI sorting engine
- HSV (Hue-Saturation-Value) set-up — five times faster than previous models
- Zero-spillage design, size sorting, reflection and transparency modes
- SPARK remote control — check sorter performance from anywhere
- Listed applications include toor dal, chickpeas (split), moong, black gram, red lentils, white peas, millet, sorghum, maize, peanuts, soybeans, sesame, blanched almonds and coffee; removes stones, glass, sticks, foreign seeds and mud balls

SORTEX A MultiVision™ and SORTEX B MultiVision™
- SORTEX A MultiVision™ — Bühler’s most sophisticated range: PROfile™ (colour, shape and size), optional InGaAs infrared for foreign material the same colour as the product, climate control, ATEX option.
- SORTEX B MultiVision™ — for mainstream, everyday high-capacity sorting, with PROsize™ to remove under/over-sized grains and brokens.
- Both: 1–5 modules, LED lighting, SmartEject™ ejectors, SORTEX ProSortX™ interface, remote access (Pulses Sorting Solutions brochure).
For rice, Bühler also offers the SORTEX S UltraVision™ and SORTEX B range (Optimised Rice Processing brochure); for nuts and dried fruit, the SORTEX F BioVision (Bühler nut sorting).
Why we recommend the SPARK Pro+
Think of the SPARK Pro+ like a multi-purpose tractor: you change the setting, not the machine. One sorter can handle several commodities through the year.
- Multi-commodity: Bühler lists toor dal, split chickpeas, moong, urad, red lentils, red beans, white peas, soybeans, millet, sorghum, maize, barley, peanuts, sesame, sunflower seeds, white pepper, blanched almonds and coffee among SPARK applications.
- Fast changeover: HSV (Hue-Saturation-Value) set-up is five times faster than previous models — switch commodity without depending on a specialist.
- Easy to operate: designed for peak performance without the need for highly skilled operators.
- Grows with your plant: 1 to 10 chutes; 1.5–2.0 t/h per channel, depending on the application.
- No product loss: zero-spillage design.
- Remote monitoring: SPARK remote control lets you check sorter performance from anywhere.
- Bühler backing: more than 25,000 Bühler colour sorters installed worldwide, with an application centre in India for trials.
