Shenzhou Decanter Centrifuge for Tapioca Production Process

The main challenge in separating Tapioca lies in the fact that it is often closely associated with other components such as protein and fiber. Traditional separation methods like sedimentation, filtration, and centrifugation are not efficient enough to separate these components effectively.

Shenzhou is professional in developing different kinds of decanter centrifuge equipment. For the tapioca production process, Shenzhou has specially developed a food-grade tapioca extraction centrifuge to realize the automatic separation and extraction of tapioca. decanter centrifuge, effectively solved this problem. This machine utilizes centrifugal force to separate the different components of a mixture based on their density and particle size. The tapioca particles are forced to the outer edge of the centrifuge and collected separately from the other components.

The use of this machine in separating tapioca is crucial because it allows for a more efficient and effective separation process compared to traditional methods. also results in a higher yield of pure tapioca, which is essential for food and industrial applications. Furthermore, the decanter centrifuge can be used for continuous separation, ensuring a steady supply of high-quality starch.

Main Technical Features

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 selection

We use origin bearings of international first-line brands such as SKF,FAG and so on.

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.
