Product Description

DDGS Dewatering Centrifuge for Use in DDGS Separation Process

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 decanter. The whole Shenzhou

DDGS dewatering decanter is equipped with high-performance wear-resistant protective materials to greatly

extends the maintenance cycle and ensure annual normal running time.

Technical Characteristics of SHENZHOU DDGS Decanter

1. 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.

2. 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 decanter has some requirements on the selection of wear-

resistant materials.

3. 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.

4. The ultra-high pushing torque requires a high-torque involute planetary gear differential as the foundation.

The differential equipped on the ddgs dewatering 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.

Our Advantages

The advantages of our product
1. Industrial design
Whole machine set design follows concept of advanced industrial design,ensures stability,functionality and safety of whole machine.Also effectively absorbs shear force of dynamic load during operation.
 
 2. Effectively ease resonance during rotating of bi-rotor
When centrifuge works,there is no obvious first-order and two-order resonance regions within designed speed range,meanwhile ,whole vibration intensity of bearing seat is definited within 2mm/s-4mm/s.All of this eliminates extra fatigue damage to components and assembly units from high frequency vibration during operation and sudden vibration when shut down.
 
 3. Thoroughly eliminate phenomenon of liquid ring stalling
Phenomenon of liquid ring stalling happens during heavy duty boot or shutdown process of complete set machine,especially for LW550 and even larger models,It would makes bounce or wild shake,causes extra impact fatigue damage to main bearings,screw bearings and inner parts of rotary bowl.Fortunately ,our engineers have solved this problem thoroughly.

 4. Unique technique adopt in main component work-blanks 
The manufacturing methods of main component work-blanks are adopt centrifugal casting technique and overall mould-making forging technique,thoroughly avoid risks such as inter-granular corrosion and relaxation of residual stress release in welding joint.
 
 5. Main bearing electrical components selection
We use origin bearings of international first-line brands such as S-K-F,F-A-G and so on.Electrical components mainly adopt ABB and Siemens
 
 6. Constant temperature detection
All fashioning components and assembly units are detected in constant temperature condition,to make sure of actual processing quality meets the requirements of designed precision accuracy.
 
 7. Inter-change ability
Whole machine physical design and processing technique adopted in critical position,ensure all assembly units and bowls of the same centrifuge model interchangeable.It is not only easy to maintain ,but also greatly improve the reliability and safety of equipment.
 
 8. Simplyand safely in bearing disassemblement
One layer of oil film is injected into contact surfaces between bearing and work-piece by high-
pressure,during disassemblement bearing from the machine.which would fundamentally eliminate friction within different parts.As a result,it would reduce 90% of pulling force and lower the risk of damage to high-precision parts when disassemble bearing.

9.Main bearing lubrication system
There are two kinds of lubrication system for specific product models :
A thin oil lubrication
 * Oil pump offers an uninterruptedly power to ensure oil works circularly;
 * Jet oil lubrication constantly clean and lubricate bearings and reduce temperature;
 * Oil filter system ensure lubricant's cleanliness;
 * Oil pressure energy storage system ensure lubrication pump offers an extra oil supply(the pressure is no less than 0.4Mpa) for  5-6 minutes,when power fails accidentally;
 * Constant temperature system is available.
B grease lubrication
 * Adopt a grease with properties of extreme pressure resistance ,oxidation resistance ,abrasion resistance,water scour
   resistance,corrosion-proof and high temperature resistance.
 * Optional automatic grease system fills grease on main bearing at designed hours and quantity.

 10.  Main bearing BH device (patent design)
There are two spare safe bearings at either end of main bearing.When machine works well,they keep certain clearance from bearing inside track to chief axis.When unexpected condition occurs,main bearing got damaged or circle center deviation causing an amplitude of vibration reaches to designed clearance,safe bearings begin to work as main bearing Meanwhile,computer automatic control system would get a feedback of abnormal vibration value on bearing position immediately then activates emergency shutdown and goes a smooth shut down.This system protects machine free from damaging and ensure production safety.
 
 11.  GSRL feeding device (potent design)
New design of internal spiral core tube has got following achieves.Without reducing centrifugal acceleration,shorten triangle belt's traction time,reduce disorder of swirling flow and extend separation time.Meanwhile increases inner working pressure of centrifuge,and restrains liquid foaming
