ENTEX Rust & Mitschke GmbH ist ein deutscher Hersteller von Planetwalzenextrudern und Kalanderwalzen, ansässig in Bochum.
Das Kernstück des Planetwalzenextruders ist ein ENTEX-Planetengetriebe mit extremer Verzahnungsbreite und einer 45° Drallverzahnung. Bei Drehung der Zentralspindel wälzen sich die Planetspindeln auf der Zentralspindel um den Walzenzylinder ab und laufen planetenartig um. Bei diesem Vorgang wird das Material erfasst und durch das Eintauchen der Spindelzähne in die korrespondierenden Zahnlücken wird das eingegebene Material zu dünnen Schichten ausgewalzt und mittels der Drallverzahnung nach vorne transportiert. Auf dem neuen Fertigungsverfahren der Tiefenerodierung basieren alle Entwicklungsschritte. 
Dieses modulare Extrudersystem mit extrem dünnen Wandstärken mit den Möglichkeiten der Druck- und Temperaturmessung, Einspritzung von viskosen Komponenten und der Entgasung macht eine kontinuierliche Aufbereitungstechnologie in neuen, bisher nicht bekannten Dimensionen möglich.
Der Vorteil dieses Systems liegt in der Dünnschichtauswalzung mit der Generierung großer Oberflächen bei geringem Schereintrag, verbunden mit der exaktesten Temperaturführung aller vergleichbaren Extruder. Neue wirtschaftliche Konzepte für Lebensmittel entstehen.
Der kontinuierlichen Aufbereitung mit dem Planetwalzenextruder, d.h. Lebensmittelaufbereitung im geschlossenen System, keimfrei und steril, gehört die Zukunft. Die Bereiche wie z.B. Kakao-Zucker-Dispersion, Eiscreme oder Babynahrung zählen zum Tagesgeschäft. Andere Bereiche wie z.B. Cerealien, Spezialmalze oder die Proteinmodifikation gehören ebenso zum Leistungsspektrum.

The KÜTTNER – Group is a leading global company in building turnkey plants for the metal producing and metal treating industry. Processing, melting and conveying units are typically part of their scope of supply. For mixing alloy pellets required in a downstream reactor, KÜTTNER was looking for a suitable mixer which would treat the products especially gently. After scale up tests at Lindor, the gentle touch mixer proved to be the perfect solution for this requirement. The mixer designed and built for KÜTTNER allows mixing of various products with powders and micro - granules.
The process
At a completely new plant in China, alloys are produced which are used as aggregates for further high value - alloys. The product is applied for components in the aircraft and space industry and also for other high tech applications. Various materials are dosed in sequence according to their specific weight in the mixer, are mixed and fed into a reactor. For the entire reactor process the reactive surface of the main component should not be too large. This is why the main components of the mix appear in the form of pellets. Micro – granules and powders are also used. It is essential here that the pelletsare not damaged during the dosing and the mixing process.Therefore “gentle touch“ mixing is a strict requirement. When investigating the market for batch mixers, the Lindor mixer was selected as the most appropriate one for gentle mixing. Tests confirmed that a very homogenous mix is achieved within a short time without damaging the sensitive pellets.
Technical specification
Powders, granulate and pellets of different sizes are mixed together. The Lindor gentle touch mixer was built out of stainless steel AISI 316L. Due to the abrasive properties of the products gland seals were integrated at both the inlet and the outlet. The mixer is equipped for the later introduction of liquid with an injection device, in order to feed in a 3 % emulsion. Mr. Schwieger, the project leader, further pointed out: “The whole co-operation with Lindor and their after sales service has been excellent!”
The KÜTTNER Group
The KÜTTNER Group, founded in 1949 by Dr. Carl Küttner, builds turnkey plants for the iron, steel and non-ferrous metal industry, as well as in the field of energy and environmental technology. KÜTTNER’s specialty is metallurgical plant engineering, including, in particular, plants for special metals, ferroalloys, non-ferrous metals and cast products. KÜTTNER designs and builds state of the art installations for foundries meeting their highest demands. Typical projects are automatic charging plants, cupola melting plants, processing plants for the serial production of green sand castings and for large castings made in no bake sand centrifugal casting plants. Thanks to its many years of experience KÜTTNER is in a position to implement even the most demanding projects for modernization and upgrading of complete foundry plants. Internationally the KÜTTNER Group is represented through a network of affiliated companies and agents.
Lindor has recently delivered a mixer for a new production line of infant formula powders in Asia. Mixing high quality infant formula powder is a delicate process. The Lindor mixer was selected for its high quality of the mixed product and production capacity.
Lindor L1000 selected for best powder quality
The manufacturer has based the selection of the Lindor L1000 mixer on the excellent mixing quality and the actually delivered production capacity (batch size 400- 500 kg, 5 – 7 batches/hour). The quality of the powder after mixing, the integrity of the spray dried particles and the homogeneity of the blend determines in a very important way the quality of the end product. Even with very small minor ingredient levels (< 1%) the homogeneity of the product is ensured. The retractable inlet and outlet, together with three large door provide ample access to the mixing drum, the inlet and outlet and last but not least the manually replaceable seals for optimal dry cleaning.
Lindor L10 lab mixer for R&D Department
The manufacturer has also purchased a Lindor L10 lab mixer for developing recipes and defining process parameters. This mixer has a maximum batch volume of 10 litres, which is in the case of infant formula about 5 – 6 kg. Due to the transparent mixing drum the actual mixing process is visible for observation.
The mixer can easily be disassembled by hand and the three components can be cleaned/washed by hand or even be washed in a regular dish washer.
Key component in state-of-the-art mixing line of AMH Technologies
The L1000 is part of a state-of-the-art mixing line designed and built by AMH Technologies. AMH Technologies is an engineering firm based in Kuala Lumpur, Malaysia, with offices in many countries in SE Asia like Indonesia, Thailand, Vietnam, Myanmar, China and Philippines. Material handling, pneumatic conveying, being a core competence of them, they integrate many components from high quality suppliers around the world. Lindor and AMH Technologies have worked together on several powder mixing projects for over 10 years. More information can be found on their website: www.amh.com.my.
