Rotary pressure filter of type RPF A09 with CenterDrive for use in the food industry

Both the indexing belt filter (BF) and rotary pressure filter (RPF) are suitable for the gentle processing of amino acids. With both machines, you can ensure a uniform, high product quality. After filtration, an efficient washing stage produces high-purity amino acid. Both systems have proven themselves in this application for decades. Our filters are also CIP-compliant for use in the food industry.

Vitamins

High-quality, sensitive vitamins should ideally be processed continuously in a closed system. The rotary pressure filter (RPF) offers the ideal conditions for this. At the same time, it ensures reliable and efficient operation in a process that can be constantly monitored. After separation of the filtrate and filter cake, the product is washed and dehumidified in several stages using a very small amount of detergent. The result is a top-quality solid material free of impurities.

Success stories

Utilizing egg yolk powder effectively thanks to continuous filtration and drying

An internationally operating pharmaceutical company extracts phospholipids from egg yolk and further processes the by-product into an additive for animal feed. Thanks to technological solutions from BHS-Sonthofen and AVA, the company succeeded in optimizing its processes. The solutions consisted of a continuous belt filter from BHS and a horizontal contour dryer from AVA, both of which are ATEX compliant and designed in accordance with GMP. AVA became part of the BHS Group in April 2018 – and the companies’ product portfolios complement each other perfectly.

Retrofitting in amino acid production: BHS supplies rotary pressure filters for the dietary supplement industry

L-threonine is an essential amino acid in both the animal and human diet and is produced on an industrial scale across the world. An American manufacturer of dietary supplements was using outdated horizontal automated filter presses to filter L-threonine crystals. BHS-Sonthofen tested its different filter systems for use in this challenging filter application, and, together with the customer, decided on rotary pressure filters as a high-performance alternative that also optimally suits the existing production process.

BHS-Sonthofen supplies hygienic-design indexing belt filter to the food industry

A Scandinavian company commissioned BHS-Sonthofen with delivering a filter system for the purpose of manufacturing lactose products. The hygienic-design indexing belt filter is the centerpiece of the installation. This choice enables the operator to phase out several centrifuges, making the new process both simpler and more cost-efficient.
