High Efficiency Separation Screen Bowl Centrifuge For Alcohol Industry

High Efficiency Separation Horizontal Fermentaion Industry Screw Decanter Centrifuge

I. Alcohol industry

Corn, wood, rice, wheat starch, etc. are the most widely used raw materials in the alcohol industry. More and more alcohol producers after fermentation and distillation use a centrifuge to remove water, which solves the issues in large-scale conventional filtration equipment, ranging from large land occupation to high labor intensity, and high later-stage maintenance cost. At the same time, by virtue of high efficiency, stability and environmental protection, it provides guarantee for efficient dehydration, DDGS quality, and subsequent process energy conservation.

When corn and cassava are used as raw materials, the high sand content in the acid solution is an important factor affecting the stability and service life of the centrifuge. The whole [ZK Separation] centrifuge is equipped with high-performance wear-resistant protective materials to greatly extends the maintenance cycle and ensure annual normal running time.

Common alcohol production process

Technical characteristics of DDGS dedicated high efficiency centrifuge

★ Special spiral structure

The DDGS high efficiency centrifuge fully draws on the working principle of the lamella settler. To improve the clarity of the supernatant after centrifuge separation, a certain number of solid particles capturing plates (referred to as spiral plates) are added to the screw conveyor at the clarification section. When the solid suspended particles flow through the spiral ramp, part of them can be effectively attached to the spiral ramp and slide along it into the blades of the screw conveyor to realize continuous slag discharging. Compared with common centrifuges, it can increase 20~30% in solid recovery rate.

★ High performance wear-and corrosion-resistant cemented carbide

The DDGS slurry produced with different raw materials through different processes has different degrees of corrosiveness, such as hydrochloric acid or sulfuric acid used at the acid chemical section, amino acid or acetic acid produced by fermentation. Therefore, the centrifuge has some requirements on the selection of wear-resistant materials.

★ High-dryness screw conveyor and drum structure

The dehydration of solid particles relies mainly on strong centrifugal force, high-torque spin extrusion force (pushing torque), and ultra-long solid particle dehydration length. The centrifuge can generate centrifugal force exceeding 3000G, 30 ~ 50% higher than the screw pushing torque of common centrifuges. The screw pusher torque, and the drum dehydration length is 10 ~ 20% longer than that of common centrifuges.

★ High torque involute planetary gear differential

The ultra-high pushing torque requires a high-torque involute planetary gear differential as the foundation. The differential equipped on the centrifuge features high torque, high speed, low heat generation, and excellent heat dispersion, which ensure that the centrifuge can be used for a long time and stably.
