Sealed Mechanical Defoamer

In modern industrial biotechnology and pharmaceutical manufacturing, excessive foaming inside pressurized vessels remains a critical challenge. Traditional chemical anti-foam additives often cause downstream contamination, reduce oxygen transfer rates, and lower overall product purity. The BODF-I Series Sealed Mechanical Defoamer offers a revolutionary, eco-friendly solution to this problem, delivering continuous, chemical-free foam control specifically engineered for fully enclosed, sterile environments.

Product Overview

The BODF-I Series Sealed Mechanical Defoamer is a premier industrial deaerator engineered to integrate seamlessly with pressurized, fully enclosed bioprocess systems. By utilizing advanced centrifugal force and high-speed mechanical shearing, this innovative machine continuously breaks down high-density foam inside sealed fermentors and chemical reactors.
By completely eliminating or drastically minimizing the reliance on chemical anti-foam consumables, the BODF-I preserves absolute system pressure and sterile processing conditions. It provides an efficient foam control mechanism that actively prevents broth entrainment and valuable liquid loss, even under demanding high-aeration operating conditions.

How the Centrifugal Foam Separator Works

The BODF-I operates on a precise mechanical cycle designed to separate gas from liquid without exposing the process to external contamination:
Foam Intake: As foaming occurs during fermentation, the process foam rises and enters the high-speed rotor work zone directly through the airtight, sealed inlet.
Mechanical Shearing: Precision-engineered dynamic rotor blades rotate at optimal speeds, applying intensive shear forces that instantly rip the fragile bubble structures apart.

Centrifugal Separation: The liquid released from the shattered bubbles is driven outward against the inner housing wall by powerful centrifugal force, compressing the chaotic foam into a dense, continuous liquid stream.
Automated Reclaiming: Utilizing the system's kinetic energy and internal piping, the reclaimed fermentation broth is continuously routed through dedicated drain lines back into the closed fermentor, ensuring zero product waste and keeping the biomass active.

Key Features

100% Chemical-Free Foam Control: Eliminates the need for expensive chemical defoamers, which significantly reduces ongoing operational costs and prevents chemical buildup in your end product.
Maximized Fermentor Loading Capacity: Removing the threat of chemical contamination allows facilities to increase their working liquid volume (loading coefficient), optimizing plant throughput and enhancing biochemical reaction stability.
Advanced Entrainment Prevention: The system pairs seamlessly with auxiliary exhaust condensation setups to capture micro-droplets, completely stopping material and broth loss under high aeration rates.
Higher Bioprocess Efficiency: By accelerating bubble collapse, it reduces the residence time of vital microorganisms within the foam layer, keeping the biomass fully submerged and functional in the liquid phase.
Flexible Industrial Connections: Engineered to meet diverse sterile requirements, the unit can be configured with Flange, Tri-Clamp (Sanitary Clamp), or Threaded connections upon request.

Target Applications

Pharmaceutical Bioprocessing: Highly suited for sterile antibiotics fermentation, vaccine cultivation, and therapeutic protein production.
Industrial Biotechnology: Ideal for large-scale production of amino acids, organic acids, and various yeast culture processes.
Food & Beverage Industrial Mixing: Widely utilized in premium vinegar brewing, high-aeration liquid mixing, and automated beverage blending.
