Chemicals & biochemicals

Solutions for the safe separation of substances

Broad product portfolio for the chemical industry

BHS-Sonthofen offers first-class process solutions for the chemical industry that are used all over the world. For optimum functionality, we not only consider the equipment itself, but also the environment in which it is operated.
 
BHS-Sonthofen is present in cake-forming filtration, both in vacuum and pressure filtration. The filtration step is often followed by drying, for which horizontal and vertical contact dryers are used. Depending on the application, batch or continuous units are available. The portfolio is rounded off by solutions for mixing tasks for solids, humidification or granulation.
 
BHS-Sonthofen will work with you to develop the optimum solution tailored to your needs. The experts at BHS-Sonthofen have decades of experience and support you in process planning and implementation on a production scale. Demanding conditions such as potentially explosive areas, corrosive, toxic or abrasive media, GMP conditions and automated cleaning cycles are part of BHS-Sonthofen's daily work.

Examples from the wide range of applications

  • Fine chemicals, construction chemicals, metal salts
  • Detergents, adhesives, paints & pigments
  • Biochemistry, food additives
  • Modified starch, cellulose derivatives
  • Biodiesel, catalysts
  • Treatment of production sludge

Safe production of agrochemicals

Safe production of agrochemicals

Whether plant protection products such as pesticides, fungicides and herbicides or fertilizers: the rotary pressure filter (RPF) is the most suitable closed system for the production of agrochemicals. The continuous and fully automatic high-performance filter offers maximum safety - and requires no manual intervention other than for maintenance. The machine enables gas-tight cake treatment in several separate process steps.

BHS vertical dryers and mixers are an excellent solution for the homogenization and drying of powdered to granular products in the agricultural industry. The fragile products are processed quickly and particularly gently and the reproducibility of the recipes is guaranteed. Thanks to the special shape of the mixing container, the product is almost completely emptied from the bottom while the mixing tool is running. The machines are easily accessible for cleaning purposes or, alternatively, the cleaning processes can be automated. The design and construction are GMP-compliant, and many variants can be selected to suit specific applications.

Safe processing of bio-based chemicals

Safe processing of bio-based chemicals

In the processing of chemicals based on renewable raw materials, the filter systems, mixers, dryers and reactors from BHS-Sonthofen ensure high product quality and yield as well as efficiency in the treatment of solids and product quality. Examples include cellulose derivatives or bio-based polyamides.

Suitable for

  • Brominated and chlorinated compositions
  • Melamine and phosphate mixtures
  • Ammonium, antimony, and boron compounds
  • Other inorganic flame retardants

Conditioning of Flame Retardants

BHS dryers, mixers and reactors are ideally suited for conditioning flame retardants. Horizontal or vertical, from 3 liter to 50 m³, with reaction temperatures of up to 500°C and pressures <25 mbar. The mixing, drying, and reaction processes can take place in one machine. In the reactor variant, a typical application is cross-linking of melamine and phosphoric acid to create melamine (poly)phosphate. In the drying mixer variant, red phosphorus, ammonium (poly)phosphate, and melamine (poly)phosphate are dried, while the mixer variant is suited, for example, to coating flame retardants with silanes to improve the surface structure.

Our machines in use
