Biochemical Processing

Precision Separation for Bio-Based Innovation

Biochemicals, chemicals produced through biological processes, are becoming increasingly important as industries shift towards renewable resources. Many such products are made via fermentation or bioconversion, followed by complex separation and purification steps.

Typical biochemicals include organic acids, like citric and lactic acid, amino acids, enzymes, polysaccharide thickeners, yeasts and yeast extracts. Producing these compounds efficiently requires careful downstream processing to isolate and purify the target molecules from fermentation broths and biomass.

Huading Separator provides advanced centrifugal separation solutions designed to meet the unique challenges of biochemical production – from biomass removal and product extraction to purification and concentration.

How Centrifuges Support Biochemical Production

How Centrifuges Support Biochemical Production

Modern centrifuges improve the downstream processing of biochemicals, ensuring high product yields and purity while improving process efficiency. By leveraging high rotational speeds and optimized designs, centrifuges can handle the diverse separation tasks in biochemical manufacturing, all while maintaining product quality and meeting industrial standards.

Biomass Separation and Clarification

Fermentation broth clarification is the first critical step after fermentation. Here, centrifuges separate microbial cells and other suspended solids from the liquid culture medium.

High-speed disc stack separators or decanter centrifuges efficiently remove the bacteria, yeasts, or fungi from the broth, isolating the valuable product that is typically dissolved in the liquid phase. This ensures minimal loss of target compounds and yields a clarified solution for further processing.

In many cases, the centrifuge concentrates the cells into a dense slurry while producing a cell-free liquor that contains the biochemical product. For example, in an enzyme fermentation, a disc separator can rapidly clarify the broth to separate spent cells from the extracellular enzyme solution.

If extremely high clarity is required, a secondary polishing step using a tubular centrifuge or a filtration unit can remove any fine residual haze.

Purification and Extraction

 

Application Type Description Equipment Used Benefits
Liquid-Liquid Extraction Separation of biochemical products (e.g., organic acids, antibiotics) from broth using solvents Disc stack centrifuges configured for liquid-liquid separation Fast phase separation, reduced solvent use, improved yield
Solid-Liquid Purification Product recovery after precipitation or crystallisation (e.g., acid salts, protein aggregates) Decanter centrifuges, mixers, and pumps Efficient product isolation, impurity removal, and batch consistency
Broth Conditioning Mixing of reagents (e.g., lime, pH adjusters) before separation Multi-purpose mixers and centrifugal pumps Enhances reaction uniformity and extraction efficiency
Polishing and Final Purity Final cleanup of product stream (removing haze, fine debris) Tubular centrifuges, pressure leaf filters Achieves high clarity, compatible with downstream refinement

 

Centrifuges are also often used in combination with filtration and membrane systems to achieve required purity levels. Their ability to handle liquid-liquid, solid-liquid, and solid-liquid-liquid separation makes them essential for biochemical purification.

Concentration and Product Recovery

In the final stage, centrifuges help concentrate products by removing water or excess liquid. This improves processing efficiency and reduces the load on drying or evaporation systems.

  • Dewaters solid products like crystals or biomass (e.g., amino acids, organic acids)
  • Thickens slurries of bio-based polymers before drying
  • Available in scales from lab to industrial production

By maximizing yield and minimizing waste, centrifugal concentration ensures products are recovered in a form ready for packaging or further refinement.

Applications in Biochemical Production

Centrifugal separation technology is applied across a broad spectrum of biochemical manufacturing processes. Virtually any biotech-derived chemical or biomaterial that requires separation of liquids and solids can benefit from disc separators, decanters, tubular centrifuges, and related equipment. Below are key applications and product areas in which Huading’s separation solutions play an indispensable role:

1. Organic Acids (Citric, Lactic, Succinic, etc.)

Organic acids such as citric, lactic, and succinic acid are core bio-based chemicals produced by fermentation. Centrifuges are involved in every major step: clarifying fermentation broth, isolating the product through precipitation or extraction, and recovering final crystals.

Whether separating fungal biomass in citric acid production or extracting lactic acid with solvents, high-speed separators and decanters enable efficient, corrosion-resistant, and high-purity processing.

2. Amino Acids and Nutritional Ingredients

Centrifuges are essential in the production of amino acids like lysine and threonine, and nutritional supplements such as B vitamins.

After fermentation, they separate microbial biomass from the product-rich broth, enabling downstream crystallization and recovery. Their gentle handling ensures high yields without damaging heat-sensitive compounds.

3. Enzymes and Yeast Extracts

Enzymes and yeast extracts are typically recovered from fermentation broth using high-speed separators. These machines efficiently remove cells while preserving delicate protein activity.

Centrifuges are also used to collect precipitated enzymes and to clarify yeast extract solutions, ensuring clean separation and maximum yield.

4. Biopolymers and Thickeners (Xanthan Gum, etc.)

Biopolymer production, including xanthan gum, gellan gum, and PHAs, involves high-viscosity or high-solid fermentation broths.

Centrifuges are used to separate biomass, recover precipitated polymers, and clarify thick solutions efficiently. Decanter and disc centrifuges handle tough slurries and enable high-purity polymer recovery with reduced energy use.
