At Interpack 2017, Spice Application Systems (SAS) will be displaying its innovative complete drum system which uses electrostatic technology to apply flavourings and coatings to a variety of products. The company has already manufactured and supplied a number of bespoke systems and here one customer explains the successful outcome of working with SAS.
The Republic of Fish AS, is a manufacturer of fish-based snack foods is based in Sommarøya in the north of Norway, where the company has been producing a 100 percent natural, handmade product called Havgull made from arctic haddock since 2008. Thin flakes of dried fish, much like potato crisps, Havgull is a traditional Norwegian and Icelandic snack, which is an acquired taste.
In 2016, the company decided to expand their product base by developing their product to appeal to a wider market, by coating it with olive oil and selected spices. Under the brand name Happy Crisps, the delicate flakes of dried fish were to be covered with ground pepper, garlic and ginger spices, maintaining the healthy properties of the snack which contains 80 percent protein and no artificial additives.
Managing Director Kristjon Bergmundsson says: "We were keen to develop a product based on the success of Havgull, but which would appeal to the taste buds of consumers not familiar with this Nordic delicacy. We especially picked spices to complement the flavour of the dried fish but also those with added health benefits."
Once the new product had been developed in theory, the company had to find an efficient system to coat it. Although Kristjon Bermundsson had been involved in the fish industry all his working life, he knew nothing about coating snacks, and so began searching for an expert in the field. But as the search continued, it became obvious that a standard 'off -the-peg' seasoning and coating line wasn't going to work for this product.
Then a recommendation came to contact a British based supplier, Spice Application Systems (SAS), which specialises in using electrostatic technology to apply flavourings, coatings, powders, additives, vitamins, spices and oils to a wide range of food products. Kristjon Bermundsson said: "On speaking to SAS, it quickly became clear that we needed a system tailored to our specific needs, and after talking to them and learning about how the coating process would work, we were confident that they would deliver."
SAS designed and engineered a range of complementary pieces of equipment which worked together to create a complete coating and flavouring system for the Happy Crisps. The system, which comprises a screw feeder, oil spray system, in-feed tray and cylindrical drum, uses electrostatics to coat the flakes.
The electrostatic technique works by applying a static charge to the powder and oil coating as it's being sprayed onto the product. As the coating become negatively charged, it adheres automatically to the positive base product, creating a true wraparound effect.
