Halal Tahini Sesame Paste Mixing Tank Stainless Steel 316L

Halal Tahini Sesame Paste and Date Paste Mixing Tank with High Shear Emulsifier 300L to 2000L Stainless Steel 316L

Paste processors across the Middle East and North Africa run their sesame lines on one critical vessel, the sesame paste mixing tank. This halal tahini unit is engineered for exactly that duty. Sesame paste, date paste and hummus are heavy, sticky and heat sensitive. Viscosity commonly sits between 5,000 and 20,000 cP at 60 to 80 degrees C, and the mass will scorch within minutes if the agitator stalls against it. Our design therefore pairs a slow counter rotating anchor agitator with a bottom entry high shear emulsifier, so the bulk product keeps moving while the homogenizer breaks down agglomerated solids and re-disperses separated oil back into the paste. Tank volumes run from 300L to 2000L, with material, agitation and heating matched to your actual recipe rather than a catalogue figure.

How the Vessel Is Built

Both shafts are independently driven through hardened helical gearboxes, so the anchor and the high shear head can be run at different speeds or started separately. The anchor turns at 10 to 30 rpm with PTFE or silicone scraper blades that sweep the inner wall and the dished bottom, eliminating the static boundary layer where paste would otherwise burn. The bottom entry high shear head runs at 2,900 rpm and pulls product up through a rotor and stator pair, generating the shear that turns a coarse sesame grind into a smooth, glossy paste. Because the high shear head is mounted at the lowest point of a conical bottom, the whole batch passes through it and no heel is left behind.

Material and Finish

All product contact surfaces are SS316L. The interior is mirror polished to Ra 0.4 micrometre or better, with ground and polished weld seams and no crevices, dead corners or exposed threads that could trap paste and harbour bacteria. The outer shell and jacket are SS304 with a 2B or matte finish. A hinged top lid with a balance spring, a sanitary sampling valve and a CIP spray ball are fitted as standard, and the discharge is a full bore conical outlet with a butterfly or ball valve sized for the viscosity of your product.

Key Specifications

Typical Applications

Tahini and sesame paste for retail and food service packing

Date paste, date syrup and date filling for bakery and confectionery

Halva and sesame confectionery base mass

Hummus, chickpea puree and bean paste

Nut butter, praline paste and marzipan

Sweet bean paste and fruit paste for mooncake and pastry filling

Certification and Compliance

The vessel is CE marked and built as food grade equipment. Product contact materials comply with EU Regulation 1935/2004 and EU Regulation 10/2011, and FDA compliant elastomers are available on request. Where the heating jacket is designed above 0.5 bar, the jacket is built and certified to PED 2014/68/EU. Full material traceability is provided through EN 10204 3.1 certificates for every product contact plate and for the agitator shafts, which is normally the first document a hygiene auditor asks for.

Ordering Information

To quote accurately we need five things from you: the working volume, the product and its viscosity at process temperature, the required process temperature profile, the discharge height above floor level, and the available power supply. Standard supply is 380V 50Hz or 460V 60Hz, three phase. Lead time is 30 to 45 days from confirmed drawing approval, and every unit is hydro tested and run tested with water before shipment.

4. FAQ

Q1. What is the smallest volume you build for tahini production?

A. We build this counter rotating design from 300L upward. Below that volume a single shaft agitator with a smaller high shear head is usually more economical, and we can supply that from 50L. Tell us your batch size and we will recommend the smaller or larger configuration rather than simply selling the bigger machine.

Q2. Can the same tank handle date paste, which is far thicker than sesame paste?

A. Yes, but the drive is sized for it. Date paste can exceed 40,000 cP when cool, so we calculate torque at the lowest process temperature and select a heavier gearbox and a reinforced anchor frame. If you plan to run both products on one vessel, give us the viscosity of each at its coldest process condition and we will size the drive for the worst case.

Q3. Why combine a counter rotating agitator with a high shear emulsifier instead of using only one?

A. A high shear head alone cannot move a 10,000 cP paste, and an anchor alone cannot reduce particle size. Used together the anchor keeps the whole batch circulating and scrapes the heat transfer surface, while the high shear head does the actual dispersion. The result is a shorter batch time and a visibly smoother product than either method achieves on its own.

Q4. How is the tank cleaned between different products?

A. The interior is fully drainable with a conical bottom and polished welds, and a CIP spray ball is fitted as standard. In practice most paste producers run a hot water rinse, an alkaline wash at 70 to 80 degrees C and a final rinse, then verify with a swab test. Because the surface is Ra 0.4 micrometre, cleaning validation is straightforward. We can supply a written cleaning procedure with the machine.

Q5. Is the equipment halal certified?

A. The vessel is built entirely from SS316L and SS304 with no animal derived components in the product contact path, and we supply material certificates proving this. Formal halal certification of processing equipment is issued by the certifying body in your own market, not by the machine builder, so we support the process by providing the material declarations, the food contact documentation and the cleaning procedure your auditor will request.
