Separation & filtration solution for food industry

Haitoglou automates its tahini and sesame seeds production plant with high-performance vibro sifters and self-cleaning filters

Founded in 1924, Haitoglou Bros SA, Greece, is a global leader in the production of sesame products. Processing up to 150 tonnes of seeds a day, Haitoglou prides itself on modern production facilities, meeting the highest standards of hygiene and automation in the industry, ensuring a premium quality product. From sesame oil and flour to seeds and tahini paste, a wealth of international bakery, confectionery and other food manufacturers, retailers and consumers rely upon the quality of Haitoglou’s products.

As the business has expanded, Haitoglou has taken the necessary steps to meet production demands, not only with capacity levels but also product quality, hygiene and operator health and safety – with Russell Finex providing high-quality separation equipment every step of the way.

The first step towards automation began in 2002, when Haitoglou sought a high-capacity automated solution to separate good sesame seeds from soft peels, broken seeds and dust. Russell Finex provided a separation solution that delivered the capacity of two spring-mounted separation units which Haitoglou had previously been using. The Finex Separator™ vibro screen helped the company reach the desired capacity of two tonnes an hour and improved grading accuracy. These multi-deck machines provide various cuts of material in one operation. In this case the larger foreign material is removed via the upper screen while smaller particles such as peel fragments and dust are removed using the lower screen.

Nikos Itskos, Haitoglou Bros SA Technical Director, comments, “We first contacted Russell Finex many years ago to provide a higher capacity solution to grade our peeled sesame seeds. We found the quality of separation and capacity was a significant improvement on the previous machines we were using, as the Finex Separator is more powerful than other separators.”

The next area of focus was the post-washing stage. Good seeds would stick to the surfaces of the washing unit and be lost during cleaning. Despite seeming like a small quantity, even if 0.1% of product was lost, considering the vast amounts of seeds processed, this amasses to a substantial loss of product. Two Russell Compact Sieve® units were installed after the washing stage to recover these seeds. Water is flushed through the washing machine and into the vibro sieves, where the seeds are then extracted from the wash water, dust and sediment. This is now an automated process, and as well as increasing product yield, production costs were also reduced by meeting modern environmental standards reducing organic material in waste water, lowering contaminated waste water disposal costs.

Mr Itskos stated, “What impressed us about Russell Finex equipment was not just the high capacity and accuracy of separation but also the large variety of machines available. If we require very fine separation or a more compact machine – this is available. When we need to grade larger material or filter liquid products – there is a solution. No other supplier has such a variety of options.”

Additional vibro sifters Russell Compact Sieve® were also installed to guarantee the quality of sesame seeds before packaging. Haitoglou had been experiencing issues with agglomerated seeds entering the final product and compromising quality. In addition, these agglomerated seeds would block the pneumatic tube transport systems used to pass the seeds from one unit to the next. Mr Itskos stated, “Even if there was one clump of product per 100kg of seeds, this would not be acceptable for Haitoglou. We promise 100% quality for our customers – any less is unacceptable. The Russell Compact Sieve guarantees the quality of our packed sesame seeds by removing any clogging or oversize.”

At Haitoglou Bros SA, the sesame seeds are either packaged or further processed to make tahini. To produce tahini, milling and sterilization processes are applied, and the resulting sesame paste must then be filtered to remove oversize contamination and guarantee a consistent, smooth product. The company invested in the Self-Cleaning Russell Eco Filter® to fulfil this requirement. These industrial filtration systems can be installed easily into an existing production line to remove oversize contamination from liquid products. A unique and continuous self-cleaning design means there is no downtime to change filter elements, and no slowing of throughput due to blockages. The filters are totally enclosed, preventing contamination – ideal for food applications.

As with the packaged sesame seeds, a final quality-check solution was installed at the end of the tahini production line. A unique high-speed Russell Compact Sieve® vibro sifter was custom-built especially for Haitoglou and installed before the packaging stage, to provide a final quality-check of quality of the tahini paste.

Haitoglou has been delighted with the level of automation, capacity and quality provided by Russell Finex equipment. Mr Itskos commented, “We are very satisfied with the Russell Finex equipment. We have vast experience in working with sesame seed products, and understand that sesame products can be very difficult to process. For us to invest in so many Russell Finex machines is testament to their quality. We now only choose Russell machines for these applications.”

With five subsidiaries around the world Russell Finex is a global leader in the design and manufacture of innovative separation equipment. Over 80 years of experience in supplying equipment to the food industry has allowed Russell Finex to secure the trust and partnership of Haitoglou, a major global brand, into the future.

Mr Itskos concluded, “Since our first purchase in 2002, we have trusted Russell Finex to supply high-quality equipment to meet the needs of our customers. We now run a completely automated sesame and tahini production line, and are very happy with the service provided by Russell Finex. From onsite tests at our factory, or trials at Russell Finex’s test facility to after sales support, whenever a new application has been identified, we have received excellent advice from the sales team. If ever we have an occasional issue, we can always talk to an engineer and rely on a fast response.”
