1.2 m³/h Decanter Centrifuge for Food Grade Liquid Separation

Decanter Centrifuge Product Introduction

1.2 m³/h decanter centrifuge is a horizontal screw discharge separation equipment designed for continuous liquid-liquid-solid three-phase processing. Constructed with corrosion-resistant stainless steel and wear-resistant components, it ensures stable operation under demanding industrial conditions. The system uses dual motors and frequency converters to achieve stepless differential speed control with energy recovery capability. It is designed to solve challenges in multi-phase separation, product clarification, and material recovery. Suitable for food, beverage, and biochemical industries, it supports efficient processing of complex fluids requiring controlled separation, hygiene compliance, and low energy consumption.

Working Principle

The decanter centrifuge operates by feeding a mixture into a high-speed rotating drum. Under centrifugal force, solids settle against the drum wall while two immiscible liquid phases separate into stratified layers based on density differences. A differential screw continuously conveys separated solids to the discharge outlet. Dual motor control adjusts speed difference between bowl and screw, enabling stable three-phase separation with energy-efficient operation and continuous discharge.
