Effective, Continuous, and Sanitary Separation in Biological and Pharmaceutical Processes

In biological and pharmaceutical processes where high-volume separation of solids from liquids is required, the use of Rotary Drum Filters is one of the most effective and engineered solutions. Behin Afzar Saz Pooya Co. meets this need comprehensively by designing and manufacturing sanitary, reliable rotary filters compliant with GMP standards.

Operation and Structure

The rotary filter consists of a perforated cylindrical drum, partially submerged in the process solution. As the drum rotates continuously, a layer of solids (Cake) forms on the filter surface, while the clear liquid (Filtrate) passes through the pores and is collected. This process is performed continuously, with high efficiency, and without stopping the production line.

Technical Features

• Material: Main body and product-contact parts are made of Stainless Steel 316L.

• Filter Drum: Available with various mesh sizes (selectable based on particle size).

• Adjustability: Variable rotation speed to adapt to specific process requirements.

• Automated Systems: Equipped with automatic cake discharge and drum cleaning (Backwash) systems.

• Hygienic Design: Fully sanitary and washable design according to pharmaceutical industry requirements.

• Control System: Process control via PLC and programmable HMI display.

Applications

• Separation of cells, biomass, or suspended solids from fermentation media.

• Pre-filtration prior to final or membrane filtration stages.

• Concentration of biological media before drying or final processing.

• Processing particle-containing solutions in vaccine, antibiotic, and enzyme industries.

• Applications in chemical, biotechnology, and food industries requiring continuous separation.

Competitive Advantages

• Customization: Bespoke design based on capacity, product type, and solution characteristics.

• High Productivity: Reduced production downtime through continuous operation.

• Efficiency: Minimum energy and chemical consumption.

• Maintenance: Ease of cleaning, maintenance, and filter replacement.

• Professional Support: Technical support, installation, and operator training by an expert team.
