Safe filtration of seed fine particulates
The refinement of seeds increases their value many times over and as a result makes them an extremely valuable product. A highly efficient separation and filtration technology is thus essential in order to highly effectively separate the resulting fine particulates and in addition ensure constant operating conditions. Moreover, additives that are hazardous to health and possible bacteriological contaminants require maximum protection of the employees.
The Herding® Sinter-Plate Filters base on pure surface filtration combines very high separation efficiency with absolutely constant operating conditions. It thus meets the high demands on the filter technology used in this field and sets equal standards compared to conventional filter media. It reliably separates even the finest particle fractions and achieves enormously high lifetimes of 15 years and more, depending on the process. Thereby the use of the Herding® filter technology provides a valuable contribution to the increase of productivity and sustainability.

SEED PROCESSING HOLLAND
Reliable dust extraction for all areas
The priority in seed processing is effective recovery of the high-quality seed from the original grain. Filtration and separation technologies are mandatory and therefore are used in all process steps of the seed treatment. The separation process require absolutely consistent extraction volume at the respective capturing points in order to secure reproducible results. Individually designed filter systems incl. efficient dust collection and high separation performance are equally indispensable in order to guarantee maximum worker safety. The Herding® Sinter-Plate Filters with uniquely high guaranteed lifetimes and absolutely constant operating conditions cover all the processes of the seed preparation highly efficiently and reliably.

Explosion protection during filtration
The composition, the grain size distribution and the specific explosion parameters of the different particulate materials in seed preparation often require due to the resulting risk of explosion a safety concept tailored to the application case.
Herding® Filtertechnik has a wide-ranging portfolio of preventative and constructive safety technology for filter units available for the user. From consultation and selection of the suitable safety concept, the safe and ATEX-compliant design of the filter units, up to their installation, commissioning, and service.
The Herding Sinter-Plate Filter offer here a unique advantage: As the only filter element on the market, the rigid body acts as a dust EX-zone barrier, whereby no potentially explosive dust atmosphere is present on the clean gas side of the filter unit.
