How to best puree fruit containing stones, or to separate fish mince from fishbone? And how to remove sinew and gristle from meat without wasting material? Every amateur chef who has already spent hours pressing fruit through a sieve with a spoon or preparing chicken soup knows these questions. In the food industry, these methods have an automated equivalent that makes time-consuming manual labor unnecessary: so-called soft separa-tors are used to gently separate the solid and soft components of a wide range of basic products. Robust, reliable drive technology components that are suit-able for the requirements of the food industry are a key prerequisite for a con-sistently high product quality.
The BAADER group, a leading manufacturer of machinery and processing plant for the food industry, developed suitable technology for the clean separation of meat and sinews or cartilage more than 40 years ago. Over time, the product range was extended, and now includes soft separators with varying performances that can be used to remove sinew from meat and poultry, to recover meat from fish, to extract pulp from fruit and vegetables, and to unpack food products. 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 standardized final product compared to manual product separation.
BAADER's soft separators were developed in the 1960s and have been constantly optimized since then, for example with regard to the cleaning options. They comply with internationally recognized hygiene standards. 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 8 mm in the perforated drum, with other diameters available on request.
