Basalt Stone Cold Milling for Sesame: Why T40 Does Not Burn Sesame

Making real tahini from sesame is not just “grinding” — it is preserving oil acids, aroma and nutrition without burning the seed during milling. That is where natural basalt stone cold milling matters. The Arabacı Makine T40 tahini mill is engineered to grind sesame without scorching it, unlike metal discs, because the grinding surface is natural basalt stone.

What Is Cold Milling and Why Does It Matter?

Cold milling means processing sesame at controlled speed with low friction and without high heat. Sesame oil is sensitive: as temperature rises, aroma fades, fatty acids degrade, colour darkens and a burnt note appears.

Cold-milled tahini typically offers:

• A lighter, natural golden colour
• True roasted sesame aroma
• Additive-free, clean-label production
• More consistent flavour and shelf behaviour

Why Basalt Stone? Why Do Metal Discs Burn?

Metal disc systems run at high RPM and generate heat through friction. Sesame oil cannot tolerate that heat — the surface develops cooked, bitter or burnt notes. Over time, metal wear can also introduce unwanted metallic taste.

Natural basalt stone offers a different engineering profile:

• Low heat transfer — the stone does not heat as fast as metal
• Natural texture — crushes and releases oil instead of cutting and scorching
• Long service life — hard, wear-resistant surface
• Food compatibility — natural mineral stone for additive-free food

When we say “T40 does not burn sesame”, it is not magic — it is the combination of the right stone, geometry and speed.

How Cold Basalt Milling Works on the T40

The T40 is a portable mill for boutique retail, spice shops, nut stores and in-store live production. With natural basalt grinding surfaces:

• Roasted sesame releases oil at low temperature
• Transparent hopper builds customer trust through live production
• Roughly 8 kg/hour additive-free tahini capacity for daily retail demand
• Portable chassis and integrated counter for compact spaces

Who Needs Cold Basalt Sesame Milling Most?

• Organic markets and spice shops promising pure tahini
• Nut retailers selling fresh tahini daily
• Boutique food brands positioning on natural stone tahini
• Clean-label producers avoiding heat-related flavour damage
• Supermarkets with live production aisles

How to Spot the Difference in Practice

• Colour: bright golden — not dark brown or blackish
• Aroma: fresh roast — no burnt or bitter edge
• Texture: silky and flowing
• Taste: clean sesame — not metallic or over-roasted

Arabacı Makine: Stone Mill Heritage Since 1944

Since 1944, Arabacı Makine has specialised in natural stone mills. Basalt used in T40 and T100 models is selected, machined and prepared with food-safe surfaces. The goal is not only to grind — but to deliver additive-free tahini while preserving sesame character.

Conclusion

Basalt stone cold milling is not marketing fluff — it is the foundation of real tahini quality. T40 makes that accessible at boutique scale: it grinds without burning, shows live production, and lets you sell additive-free tahini with confidence.
