Sophisticated separation technology depends on reliable drives
Published: 13 July 2012 - Heather Ramsden
Soft separators are used in the food industry to gently separate the solid and soft components of a wide range of basic products. Robust, reliable drive technology components that are suitable for the requirements of the food industry are a key prerequisite for a consistently high product quality.
The BAADER group has a range or soft separators with varying performances that can be used to remove sinew from meat and poultry, to recover meat from fish and to extract pulp from fruit and vegetables. In BAADER soft separators, a toothed chain powered by a geared motor is used to move a squeezing belt. The squeezing belt transports the product to a perforated drum and squeezes the soft components through the perforation, while the solid particles remain outside of the drum. An adjustable cylinder allows users to adjust the yield/quality ratio.
This method ensures maximum product quality and minimal temperature increase. Thus, the cell structure of the source product is not destroyed, since the squeezing belt system offers sufficient flexibility. At the same time, unwanted solid components are kept out of the end product during meat processing. Last but not least, the method results in considerable time savings and a standardised final product compared to manual product separation. In several models, helical bevel geared motors from NORD Drivesystems serve as drive units. One example is the BAADER 605 type, which reaches a maximum performance of approximately 3,000 kg per hour depending on the hole size in the perforated drum, the feeding type, the product, the feeding temperature and the selected pressure – thereby qualifying for continuous large volume processing. Users can choose a hole diameter of 1.3, 2, 3, 5 or 8mm in the perforated drum, with other diameters available on request.
BAADER uses the SK 9016.1, SK 9022.1 and SK 9042.1 gear unit types. These drives owe their long life endurance partly to the Unicase design of NORD's geared motors: the housing, which is made from a single-piece casting with integrated bearing seats, eliminates all sealing surfaces that could deflect under the effect of torque or radial forces. The high-efficiency gear units with durable, wear-free gear teeth also contribute to high reliability during operation.
