Product Description

Product Description

Industrial disc centrifuges for the efficient separation of biomass in fermentation processes

Fermentation processes are a key process step in industrial biotechnology. The chemical, pharmaceutical and food industries use fermentation to produce high-value products and active ingredients from bacteria, yeasts or fungal cultures. Advanced industrial centrifuges can be used to extract these fermentation products from the fermentation broth (downstream processing).

 

Customized solutions

Shenzhou is the only supplier of industrial centrifuges whose product portfolio includes decanters, tubular centrifuge and disc separators which feature discontinuous and continuous discharge. Shenzhou always has the optimal separation solution, adapted to the customer's requirements and process. 

Competent support

In addition to the premium quality of our separation solutions, we support our customers with in-depth consulting and laboratory tests. This is followed by pilot tests through which the machine is precisely configured with commissioning and process optimization at the customer's site and integration into the overall plant. 

Hygienic design

Our machines for the biotechnology sector all feature hygienic design and can be easily integrated into existing, fully automated CIP processes. 
 

The process of separating biomass after fermentation

In biotechnological processes, the decanter centrifuge separates the microorganisms used from the fermentation broth after fermentation. Depending on the product, the patented Shenzhou centrifuge is often used instead . It combines the advantages of a decanter and a separator and is specifically designed for soft, free-flowing solids.  The aim is to thoroughly dewater the biomass in order to achieve the highest possible yield. In a second step, if necessary, the Shenzhou separator clarifies the separated fermentation broth so that the purest possible liquid is available for further process steps. This usually contains the actual recyclable material. 

Centrifuge machine Standard design

The machine consists of a frame that has a horizontal drive shaft with clutch and brake, worm gear , lubricating oil bath and vertical bowl spindle in the lower part.

The bowl is mounted on top of the spindle in the lower part. The bowl is mounted on top of the spindle , inside the space formed by the upper parts of the frame , the ring solid cover, the collecting cover, and frame hood . The feed and liquid discharge system , including the paring disc pump for the heavy phase, also rests on this structure. All parts in contact with the process liquid are made of stainless steel. The bowl is of the solid-ejecting disc type with hydraulic operating system. The electric motor is of the variable frequency drive type or of controlled-torque type.

Customized solutions for high product quality

Depending on the customer product and process, yeast, fungal cultures or bacteria are used in fermentation. These microorganisms must be efficiently separated from the biomass to create liquid with the highest possible purity for further processing. Cell separation, also referred to as downstream processing, is carried out by Shenzhou centrifuges. They mechanically separate the recyclable material from the fermentation broth. For the highest possible purity of the liquid, it is important that the centrifuge is precisely designed for the respective process. With our decanters centrifuge, separators and nozzle separators, we have the right solution for every process. Work together with our biotechnology experts, to fine-tune the details and optimize operating parameters for the best separation results and high product quality.

Operating principles

Separation takes place inside a rotating bowl. The feed is introduced to the rotating centrifuge bowl from the top via a stationary inlet pipe (1),and is accelerated in the distributor(2),which was specially designed to ensure smooth acceleration of the feed liquid(4). Leaving the distributor, the feed enters the disc stack(3). The separation into liquid-liquid-solid takes place between the discs, with the oil phase moving through the disc stack to the centre. When it reaches the centre, it is discharged through hole (5) and ejected into the collecting frame. The water and heavy solid separated from the oil move to the periphery, and the water flows via channels in the top disc(6) to the paring chamber, where it is pumped out of the rotor by means of a built-in paring disc(7).During purification, hot water is fed into the inlet of the bowl before the process liquid is introduced. The water forms a seal around the outer edge of the top disc. The solid collect in the periphery where they are discharged intermittently via the centrifuge cyclone. The solid are discharged by means of a hydraulic system, which forces the sliding bowl bottom(8)to drop down at preset suitable intervals, thus opening the solid ports at the bowl periphery

How it works

the disc centrifuge separates solids and one or two liquid phases from each other in one single continuous process, using extremely high centrifugal forces. When the denser solids are subjected to such forces, they are forced outwards against the rotating bowl wall, while the less dense liquid phases form concentric inner layers. The area where these two different liquid phases meet is called the interface position. This can be easily varied in order to ensure that the separation takes place with maximum efficiency. Inserting special plates (the "disc stack") provides additional surface settling area, which contributes to speeding up the separation process dramatically. It is the particular configuration, shape and design of these plates that make it possible for a disc stack centrifuge to undertake the continuous separation of a wide range of different solids from either one or two liquids. The concentrated solids phase formed by the particles can be removed continuously, intermittently or manually, depending on centrifuge type and the amount of solids involved in the specific application.
