NOZZLE SEPARATOR

Overview

Nozzle separators are continuous disc centrifuges primarily designed for solid particle separation, with a greater emphasis on solid removal than self-cleaning separators. They are suitable for fermentation and concentration products with high viscosity, high dry matter content, and high protein content. Nozzle separators are widely used for classifying solid particles, solid dehydration, washing, and clarifying liquids with high solid concentrations. They can also be used for three-phase separation, simultaneously separating two liquid phases and one solid phase. When configured as clarifiers, nozzle separators are referred to as concentrators, used to concentrate solids from suspensions.

How does a nozzle separator work?

The nozzle separator is used for continuous separation of solids and liquids, ensuring efficient clarification or separation. The material to be separated enters the drum through a fixed feed pipe and is gradually accelerated to operational speed by the distributor.

Large solid particles are directly separated in the centrifugal field of the nozzle separator, while finer solid particles are further separated as they pass through the disc stack. The solid particles are collected in the solid chamber on the outside of the drum and are continuously discharged through the nozzles. The clarified liquid flows out from the disc stack and is discharged under the pressure of the impeller.

The separated solids are continuously discharged through the nozzles on the outer rim of the drum. The nozzle separator is equipped with a hydraulically operated discharge system, which can trigger partial or full discharge during the separation process. The advantage is that, when processing difficult-to-separate products, the separation time can be extended and the cleaning process optimized. Time control and process-related injection functions help optimize the cleaning of the nozzles, drum, and discs.

HUADING Nozzle Separator Features

Low Wear Design

The nozzle separator saves energy through innovative design, reducing the need for drive energy. The drum is lighter, lowering power consumption while ensuring low vibration and high reliability. The built-in solid chamber prevents the formation of deposits and ensures smooth discharge of concentrates.

High Performance and Easy Maintenance

With a powerful drive system and inverter, the separator ensures fast acceleration and efficient operation. The fully enclosed lubrication system protects the equipment and extends its service life. The nozzles and spindle drive system are easy to maintain, reducing downtime.

Hygienic Design

All parts in contact with the product are made of high-quality stainless steel, meeting hygiene standards and supporting CIP (Clean-in-Place) cleaning, ensuring easy cleaning of the equipment.

Efficient Discharge and Self-Cleaning Function

The optimized nozzle design reduces energy loss, and the discharge angle improves efficiency. The nozzles can clear material without disassembling the machine.
