Separation solutions from BHS-Sonthofen have a proven track record across the globe when it comes to the extraction of valuable substances from plant-based raw materials. The high-performance filter systems deliver efficient processes and ensure natural purity and consistent quality of the end product. Our machines are successfully used both in continuous production and batch operation.
Other typical applications include biomass, lupines, algae, maize silage, elephant grass, St. John’s wort as well as willow and birch bark.
In natural substance extraction applications, plant residues are first suspended in water or solvents and filtered subsequently. Our indexing belt filters (type BF) and rotary pressure filters (RPF) are perfectly suited for solid-liquid separation. Both systems are closed units that allow several stages of filter cake treatment to be performed. The valuable resources are dissolved from the liquid in a way that is gentle on the product. They can then be further processed in many ways that serve the needs of the pharmaceutical or food industry. The systems deliver high yields despite very low consumable requirements.
