Centrifugal Screen—Pulp-Solid Separation Equipment in Potato and Cassava Starch Production Lines

Centrifugal Screen—Pulp-Solid Separation Equipment in Potato and Cassava Starch Production Lines - Manufacturer of Complete Cassava Starch Machine

In production lines for processing sweet potato, potato, cassava, and arrowroot starch, there is a piece of equipment called a centrifugal screen. Its primary function is to separate pulp from starch. After tuber materials such as sweet potatoes, potatoes, cassava, and arrowroot have been washed and crushed, the crushed material must undergo separation of fiber and starch; this is a critical step in the starch processing process. Centrifugal screens are classified into two types: vertical centrifugal screens and horizontal centrifugal screens.

A centrifugal screen is a device that utilizes centrifugal force to achieve solid-liquid separation or powder screening. Its working principle involves generating centrifugal force through a high-speed rotating drum, causing the liquid to be discharged through filter holes while solid particles settle on the inner wall of the drum and are discharged via mechanisms such as a screw conveyor, thereby enabling continuous separation operations. In sweet potato and potato starch processing, centrifugal screens can efficiently separate starch from fiber impurities. They feature multi-stage screening capabilities, ensuring low starch loss rates. Centrifugal screens are typically constructed of stainless steel and equipped with anti-clogging designs, intelligent control systems, and wear-resistant components (such as tungsten carbide coatings) to enhance continuous operation capacity and service life. Generally, large-scale starch processing facilities are equipped with horizontal or vertical centrifugal screens

Core components include the drum system, power unit, filtration mechanism, and support structure:

    Drum System: Features a ring-shaped stainless steel structure with solenoid valves controlling the feed pipes arranged around the outer circumference; an internal viewing window allows real-time monitoring of the separation process.

    Power Unit: A rotary motor drives the drum via a shaft, with a maximum speed of 3,200 rpm; a pulley drive system ensures stable power output. 

    Filtration System: Features dual filtration layers consisting of a screen mesh and filter plates; some models are equipped with removable filter plates (quickly installed and removed via connecting blocks and mounting slots) 

    Adjustable Support: A combination of curved plates and hydraulic rods allows for adjustment of the equipment’s tilt angle, while wheel assemblies assist with movement and positioning.

It is important to note that different models of horizontal centrifugal screens vary in motor power, processing capacity (e.g., hourly throughput), and applicable particle size range (typically 40 microns to 5 millimeters). When selecting a model, it should be matched to the specific material characteristics and production requirements.
