Industrial Disc Centrifuge Separation Equipment

Product Overview

A disc centrifuge is a high-speed rotary separation device designed for high-precision liquid-solid or liquid-liquid-solid separation. Its core structure consists of a set of vertically stacked discs, which, at high speed, create multiple short settling paths, significantly improving separation efficiency. Disc centrifuges offer high processing capacity, high separation precision, a high degree of automation, and continuous and stable operation. They are widely used in industries such as bio-fermentation, pharmaceuticals, plant extraction, food and beverages, and chemical oils and fats, making them an indispensable key piece of equipment in modern production lines.

Working Principle

When a mixed liquid enters the disc centrifuge through the center feed port, the high-speed rotation generates a powerful centrifugal force, rapidly separating components of varying densities radially. Solid particles or heavy liquids settle to the outer edges of the discs, while light liquids flow toward the center and are discharged through the liquid phase outlet. The multi-layered disc design significantly shortens the settling path and increases sedimentation velocity, making the disc centrifuge particularly suitable for processing complex systems such as fine particles, emulsions, and fermentation broths.

Technical Advantages

Disc centrifuges offer outstanding features such as a compact footprint, high throughput, and fast separation speeds. The equipment can be equipped with an automatic slag discharge system and a PLC intelligent control system, enabling unattended operation and improving efficiency. Depending on the customer’s material characteristics, we can manufacture key components using 316L stainless steel, duplex steel, or titanium alloy, ensuring long-term stable operation in highly corrosive, high-viscosity, and high-temperature environments. The fully enclosed design also effectively prevents cross-contamination, making it particularly suitable for the food and pharmaceutical industries.

Applications

Disc centrifuges are suitable for nearly every industry requiring precision separation. In the dairy industry, they enable milk skimming and cream extraction; in plant extraction, they separate oil, water, and plant residue into three phases; in biopharmaceuticals, they are widely used in critical processes such as bacterial isolation, cell fluid purification, and vaccine clarification; and in the chemical industry, they can handle highly concentrated and corrosive emulsion systems. Whether for continuous, high-capacity production or precise, small-batch separation, disc centrifuges provide efficient and reliable solutions.
