produce a continuous cut. There are spring based machines that built a pressure between the blades and the hole plates by means of springs. However, these systems are rarely used in pet food produc-tion because it is not possible to make accurate adjustments and the force of the springs reaches its limits when rigid products are cut. Simple systems with mechanical adjustments are more effective. That is why mechanical system with electronically controlled adjustments of the set of blades are most widely used. Electronic controls also compen-sate the effects of wear and tear. Different solutions Inotec uses a modular cutting system that consist of between one and four subsequently arranged cutting stages (rotors equipped with blades and hole plates). This system works in a coarse – fine sequence. The rotors equipped with the blades are designed to suck the product towards them. This sucking effect is enhanced by a rotating ejector installed after the cutting system. The special thing about the Inotec ejectors is a white floating seal that closes the gap between the hole plate and the ejector. This patented ejector makes it possible that Inotec machines are able to work one stage more coarsely than other machines. This result is a higher degree of fineness, more efficient machine performance and reduced production costs (coarse hole plates are cheaper then finer ones). Both in pet food and human food production sys-tems with a higher number of cutting stages allow for a finer graduation. In this way, the product is cut more effectively, which results in improved binding qualities (higher degree of protein decom-position). In many cases it is possible to optimise recipes by resorting to four-stage cutting systems. If the fineness of the final product is accurately defined it is possible to add less finely ground meat into the cutter. This ensures a higher productivity of the entire production process. If the raw materials has particular particle sizes, the final product can be cut more finely. In order to achieve the desired degree of fineness (avoiding pieces of bones in the pet food) in most cases tow machines are arranged in a row (tandem arrangement). An Inotec cutter equipped with a higher number of cutting stages helps to reduce operation costs because only one cutting machine is required in order to achieve the desired degree of fineness. At a first glance, the topic of investment costs is the most obvious ad-vantage of these machines, however, the operating life also reduces production costs considerably. Cutting machines used in pet food production re-quire a very high motor performance and less wear materials are used (hole plates and blades). Wear and tear occurs during each cutting operation – especially if the raw material contains a high pro-portion of bones and cartilage. Inotec is the only supplier of cutters equipped with automatic adjust-ments of the set of blades, which compensates for the effects of wear and tear during operation. This solution used hole plates that are moved in certain intervals and very accurately towards the fixed set of blades. This process happens automatically and is not even noticed by the operator. The result is a uniform fineness of the product – a good basis for further processing steps. www.inotectechnology.com PETFOOD TIERFUTTER Automatisierungstechnik Intralogistik/Lagertechnik Rohrbahnfördertechnik 2015 57 Foto: Inotec Behälter-/Kartonfördertechnik Zerlegetechnik Sonderlösungen Maschinenbau Helmers GmbH Dörfel Lebensmitteltechnik GmbH&Co.KG Fürstenauer Weg 70 49090 Osnabrück Tel: 0541-139020 info@maschinenbau-helmers.de www.maschinenbau-helmers.de Anuga FoodTec Halle 10.1 • Stand D010 E011
