NEO MAKİNA ve MÜHENDİSLİK A.Ş. builds turnkey sesame processing plants for tahini-grade, bakery-grade and biscuit-grade sesame. Comprising cleaning, soaking and hulling, flotation hull separation, centrifugal dewatering, fluidized-bed drying, roasting and tahini milling sections, the line delivers white, glossy, long-shelf-life product with AISI 304/316 hygienic design and low water and energy consumption.
Process Flow
A. Pre-cleaning
- Screen and aspirator: Removal of dust, stems, stones and light impurities; magnet and destoner.
- Optical sorting (optional): Rejection of discoloured and defective seeds.
B. Wet Section: Soaking, Hulling and Hull Separation
- Soaking tanks: Hull swelling at controlled temperature and time; water temperature and flow monitored by automation to prevent excess water uptake by the seed.
- Hulling mixer: Turbulent water flow and friction loosen and remove the hull; gentle design that does not break the seed.
- Flotation unit: Light hulls float while heavy seeds sink by density difference; separation efficiency above 99%; brine or clean-water process.
- Washing and rinsing: Multi-stage rinsing; closed-loop water regeneration cuts water consumption by up to 40%.
- Centrifugal dewatering: Free water removed mechanically; dryer fuel consumption falls.
C. Dry Section: Drying, Roasting and Cooling
- Fluidized-bed dryer: Drying in suspension with hot air; every seed heats uniformly without burnt spots; final moisture below 4%.
- Roasting (for tahini): Controlled roasting at 120–180 °C in rotary drum or fluidized-bed roaster; aroma and colour recipe.
- Cooling: Rapid cooling to ambient stops oil oxidation.
- Final screening and packing: Sizing, metal detection, 25 kg bags or big-bag filling.
D. Tahini Production (Optional Section)
- Stone mill or colloid mill grinding to 20–40 microns; vacuum mixing, holding tanks and filling line.

Why NEO MAKİNA?
- Product quality: Fluidized-bed drying gives uniform colour, unbroken seeds and long shelf life.
- Recipe flexibility: Soaking time, temperature and roasting profile selected per product type on the touch panel.
- Low operating cost: Water regeneration, centrifugal pre-drying and heat recovery save water and fuel.
- Durability: Bearings and frames resistant to saline and acidic conditions; 24/7 seasonal operation.
- Single-source delivery: Process design, equipment, installation, automation, commissioning and training.
Frequently Asked Questions
Brine or clean-water hulling?
Brine flotation eases hull separation but requires salt recovery and rinsing. The clean-water process produces less wastewater; the choice depends on product target and wastewater infrastructure.
Can the hulls be used?
Yes. Separated hulls are dried for feed additive or fuel; a hull dryer is added as an option.
What is the project duration?
Engineering and manufacturing take 4–6 months, installation and commissioning 1–2 months.
