Product Description

Product Description

High Speed Industrial Decanter Soybean Protein Decanter Centrifuge

Decanter centrifuge is a horizontal separating decanter with a cylindrical-conical solid wall bowl for the continuous separation of solid and liquid.
The solid-wall bowl has a cylindrical section for efficient separation and clarification of the liquid. The product enters the
decanter through the feed tube and passes through the distributor into the centrifugation space. The liquid level in the bowl is adjustable via regulating plates. Due to the centrifugal forces, the solid particles are forced to the bowl wall and are transported by the decanter scroll to the solids outlet.The liquids are separated in the separation zone And discharge

High Speed Industrial Decanter Soybean Protein Decanter Centrifuge
Soy protein isolate is the most concentrated form of low-fat, high-protein nutrition currently available, and is in great demand.The most hygienic and efficient way to process soy protein isolate is with Food decanter centrifuges from Shenzhou.

 

 

High-efficiency process flow chart - soy protein isolate

 

The process

The principles used in the production of soy protein isolate are basically simple. Using defatted soy flour or flakes
as the starting material, the protein is first dissolved in water. The resulting solution is then separated from the solid
residue. Finally, the protein is precipitated from the solution, and then separated and dried.

The objectives

For companies in the soy protein industry, the prime objectives are to improve both product purity and yield. These depend on many different parameters, including alkalinity, extraction time, temperature, the ratio of water to soy meal, heat treatment and agitation.

Protein extraction

The soy meal is mixed with water and isoelectrically adjusted so that the majority of the protein goes into
solution. This protein-rich solution must then be separated from the solid matter (known as okara). A traditional configuration for doing this features extraction consisting of vibrating and rotary screens, followed by optional purification and concentration.

However, Shenzhou decanter centrifuges are ideal as a replacement for such traditional systems, because of their extreme efficiency and high solids handling capacity.

Protein precipitation The protein solution is now isoelectrically adjusted still further so that the protein can be precipitated. The solidified protein (known as curd) must then be separated out.Shenzhou Food decanter centrifuges are widely considered the preferred choice for this process. This is due to their exceptional solids handling capacity, high standards of hygiene and low cleaning and maintenance requirements.

Curd washing

The precipitated protein (curd) is separated from the supernatant (whey) using a decanter centrifuge. This curd must then be washed in order to remove any whey residues. Thorough washing is an important step in obtaining soy protein isolate of high purity.

This is achieved by re-suspending the curd in water and then using a decanter centrifuge to separate the two components. Recovery can then be improved still further using an Shenzhou disc stack centrifuge. The washed "isoelectric soy protein isolate" can then be spray-dried, or neutralized and then spray-dried to form so-called proteinates

How it works

How does it work
The feed product is pumped into the decanter centrifuges through the inlet. Feed goes into a horizontal bowl, which rotates. The bowl has is composed of a cylindrical part and a conical part. The separation takes place in the cylindrical part of the bowl. The fast rotation generates centrifugal forces up to 4000 x g. Under these forces, the solid particles with higher density are collected and compacted on the wall of the bowl. A scroll (also screw or screw conveyor) rotates inside the bowl at a slightly different speed. This speed difference is called the differential speed. This way the scroll is transporting the settled particles along the cylindrical part of the bowl and up to the end conical part of the bowl. At the smallest end of the conical part of the bowl, the dewatered solids leave the bowl via discharge opening. The clarified liquid leaves through a paring disc (internal centripetal pump).
3-phase separation with a decanter

With a 3 phase decanter centrifuge, it is possible to separate 3 phases from each other in one process step only. For example, two liquids which cannot be mixed because of different densities (e.g. oil and water) are separated from a solids phase. The heavy liquid (water) collects in the middle between the oil and the solids layer. Thus the two liquids separated from each other can be drawn off from the decanter. The solids are transported via the scroll to the discharge openings as it happens also in 2-phase separation.
Typical applications of 3-phase separation are the production of edible oils such as olive oil, oil sludge processing, the
production of biodiesel etc.
Parameters and influencing factors of the separation

Feed, throughput and residence time

Through the feed, the separation medium to be processed can be input into the center of the infeed chamber of the scroll, where it is accelerated. The throughput will have an influence on the residence time.
Decanter Centrifuges Acceleration
The separation medium reaches its maximum speed in the decanter bowl, causing the solids to settle on the bowl inner diameter. A characteristic feature of the bowl is its cylindrical/conical shape.
Differential speed

There is a differential speed between the decanter bowl and the scroll, which is created by a gear unit on the industrial decanter centrifuges. The differential speed determines the solid content in the outfeed.
Filling volume / Weir discs or overflow weir
The clarified liquid flows to the cylindrical end of the bowl in the decanter centrifuge, from where it runs out through openings in the bowl cover. These openings contain precisely adjustable weir discs/weir plates by means of which the pond depth in the bowl can be set. The weir discs determine the filling volume of the bowl.

Advantages and limitations over competitive processes
Generally the decanter centrifuge has more advantages than disadvantages; however, there are some limitations when compared to other processes.
Decanter Centrifuges Advantages:
* Decanter centrifuges have a clean appearance and have little to no odor problems.
* Not only is the device easy to install and fast at starting up and shutting down but also only requires a small area for
operation compared to other competitive processes.
* The decanter centrifuge is versatile as different lengths of the cylindrical bowl section and the cone angle can be selected for different applications. Also, the system can be pre-programmed with various design curves to predict the sludge type, while some competitive processes, such as a belt filter press, cannot change the belt type to operate for different sludge types. Its versatility allows the machine to have various functions such as operating for thickening or dewatering.
* The machine can operate with a higher throughput capacity than smaller machines. This also reduces the number of units required.
* The device is simple to optimize and operate as it has few major variables and reliable feedback information.
* The decanter centrifuge has reduced labor costs compared to other processes, as it requires low continuous maintenance and operator attention.
* Compared to some competitive process such as the belt filter process, the decanter centrifuge has more process flexibility and higher levels of performance.

Decanter Centrifuges Limitations:
* The decanter centrifuges cannot separate biological solids with very small density differences, such as cells and viruses. A competitive process that is capable of separating these difficult-to-separate solids is the tubular-bowl centrifuge.
* The machine can be very noisy and can cause vibration.
* The device has a high-energy consumption due to high G-forces.
* The decanter centrifuge has high equipment capital costs. Hard surfacing and abrasion protection materials are required for the scroll to reduce wear and therefore reduce the maintenance of the scroll wear.
