S + S的分离和分拣技术有限公司勋伯格，巴伐利亚，2011年是一个好年景。随着增长15％，S + S达到约34万欧元的营业额，员工人数增加，从250到300左右。

2012年，S + S是规划一些转岗。职训局在今年年初集团收购了S + S的70％的股权，从而形成了公司的成功发展的基础上。一个重要的步骤是业务单位的主要经营部门PLAST，食品，和排序的组织分工。这使得S + S的，甚至更注重对各自行业的要求，并提供定制的解决方案，为每一个单独的应用程序。此外在2012年，S + S在勋伯格的工厂在建设项目计划投资约三百万欧元。对于在该公司历史上首次的员工在公司总部在勋伯格的数量预计将增加显然更超过300。

“九个月后，S + S成为职训局的组的成员，现在很清楚，我们已经达到了我们一个健康的公司，就是对未来的最佳定位目标。，S + S不仅确保企业继承，S + S的还已建立成功的增长在2012年和今后几年的基础上，在德国和国外所需的投资“说，S + S的常务董事Helmuth

MAGBOX MXF Food/Pharma is predominantly used in food, pharmaceutical , and industries where high performance is critical. The high-quality, high-performance unit guarantees efficient separation of fine ferrous contaminants and magnetised stainless steel particles. Each variant has the proven S+S EASY CLEAN feature which offers straightforward maintenance and quick, simple cleaning.

Improved hygienic design details for the MAGBOX MXF include a  latched handle for removing the magnet cores from their casing, and stainless steel star screws with captive bolts for opening the inline magnet. Every component is designed for easy cleaning.

Stephan Treml, S+S Product Manager for magnet systems, adds: "Our objective is to provide premium quality magnetic separators. With the new MAGBOX MXF the system design improvements have further achieved this objective. Fully welded gap-free casings prevent any product residue deposits, and one piece integral seals guarantee a perfect seal. System handling was also important in our brief for redesign. For example, the star grips are captive and cannot be lost plus, being stainless steel are very easy to clean."

Schönberg, July 2010
RecyPET AG was established in 1998 and has operated Europe’s first bottle-to-bottle PET recycling plant in Fraunfeld, Switzerland, since September 2000. The PET recycling plant operates in accordance with the URRC technology developed by the United Resource Recovery Corporation (USA) together with Coca-Cola and has an input capacity of approx. 18,000 tonnes per year. Four further plants in Europe now use this technology.

 In Switzerland the collected beverage bottles are sorted in five sorting plants according to colour and quality, compressed into balls and delivered to RecyPET AG, among others, for processing. RecyPET’s goal is to close the material cycle for PET beverage bottles. The recyclate produced is used among other things for the production of new PET beverage bottles, food packing films, other films, etc.

S+S Separation and Sorting Technology supplied a metal separator of the type PETMAG to RecyPET as long ago as 2001. The PETMAG separates metal contaminants of all kinds from PET flakes. Since the flakes are also to be sorted according to colour, S+S, in close cooperation with RecyPET, adapted a colour sorting machine originally used in the glass recycling industry to the requirements of PET recycling. The result was the SPECTRUM colour separator. By means of double-sided inspection it was possible even to separate flakes contaminated with the slightest glue residues.

In 2010 the PETMAG metal separator, which during its ten years of operation caused service and spare part costs of barely 2000 Euros, was replaced by a combined system of the latest generation, the VARISORT COMPACT. Colour and metal sensors are combined with one another in this device.

The material to be examined is fed by means of specially adapted vibrating trough conveyors and unites the advantages of chutes and belt systems. This also makes it possible for the first time to remove rubber pieces from the material stream that are difficult to separate using chute technology due to varying friction. The superiority of VARISORT COMPACT over chute systems
with channels lies in the fact that the equipment is easy to clean and blockages due to larger flakes can virtually be ruled out. Even in the case of irregular parts or materials with different
coefficients of friction, the belt feeding system provides for pinpoint ejection in free fall at the end of the belt, after the material has been classified with the sensors. After evaluation of the relevant information, high-speed valves for the material discharge are activated with an appropriate time delay. By means of powerful compressed air pulses, the particles to be separated are diverted from their original drop parabola into a separate shaft.

In comparison to conventional belt sorting systems, the VARISORT COMPACT sorting system is characterised by a compact design requiring little space. Retrofitting in existing plants and the adoption of already existing chute devices is easily possible. The use of high-resolution sensors and state-of-the-art signal processing technologies allows high detection accuracy and the analysis of up to 500,000 parts per second. By means of the free-fall inspection, a very precise blow-out procedure can be realised even with high rejection rates. This is made possible by the large number of high-speed valves, which can perform up to 500 switching cycles per second.

For Kornel Büsser, production manager at the Swiss company RecyPET AG, the long-standing cooperation with S+S has proven its value: “The reliability and ease of maintenance of the S+S units convinced us, together with their performance, particularly in the separation of difficult contaminants.”

S+S Separation and Sorting Technology GmbH will present their whole product range at Drinktec/PetPoint 2009 in Munich in hall B3, booth 206, from 14/09/2009 to 19/09/2009: Sorting

Systems to recycle plastic packaging, inductive metal separators, often used during the production process of PET pre-forms or closing caps, as well as magnetic and metal separators for contamination detection in liquid and pasty products, used during drink production. The highlight of the show will be the new Flake Purifier to recycle plastic drink packaging.

The Flake Purifier will be introduced to the public at PetPoint 2009, after its American launch at NPE 2009. Based on a modular concept, this machine can combine up to three sensors for contamination detection. In addition to the third generation of refined sensors for metal and colour separation, the Flake Purifier is also equipped with a high-performance module to recognise contamination, including different types of plastic. This means, PET flakes can now be separated from PVC flakes or organic material such as PLA (previously known to lower the quality of the recycling material dramatically or making high quality recycling impossible). The intelligent combination with camera sensors enables the Flake Purifier further to identify and separate dark blue and black particles. Inductive sensors detect metal contamination. Until now, established flake sorters have used only two sensors (metal and colour). The newly introduced multi-spectral sensor makes it possible to complete three sorting tasks simultaneously.

Depending on the application, PET recognition can be programmed as good material or contamination. The new Flake Purifier stands out through its compact and modular design and low power consumption, as no cooling unit is necessary. The Equipment can also be ordered with simple sensors, which can be replaced by multi-spectral sensors at any time, should the sorting requirements change. To sum it up, the new sorting system is a cost-effective solution, guaranteeing high quality recycling results.

Peter Mayer, sales manager for sorting technology at S+S, about the comprehensive product range S+S will present at the PetPoint 2009:

"In addition to PET recycling, we will also show equipment for quality assurance in PET production and for consumer protection in drinks production. It is the strength of S+S to offer both, Drintec visitors and the PetPoint target group alike, comprehensive and well developed inspection and separation solutions."
