Disc separators from Huading Separator are designed especially for liquid-based applications. Using centrifugal force, they separate substances and solids from liquids. They are equally as effective at separating liquid mixtures at the same time as removing solids.
Disc separator have become indispensable in all sectors; in fragmentation and enzyme treatment in the chemical and pharmaceutical industry, oils and fats recovery, the production of dairy products, beer, wine, fruit and vegetable juices. As stand-alone machines or integrated in complete process lines, Huading Separator’s extensive product line offers value adding solutions that point the way forward for the entire branch in terms of quality and customer benefit.
The disc separator, or disc stack separator, comprises a rotating assembly bowl operating at high speed, a drive mechanism and a cast base frame.
How a disc stack centrifuge works
A disc separator 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.
The concentrated solids phase formed by the particles can be removed continuously, intermittently or manually, depending on disc separator type and the amount of solids involved in the specific application. The clarified liquid phase (or phases) overflow close to the rotating axis, in the outlet area on top of the bowl. The liquids then flow into separate chambers. Each separated liquid phase then leaves the bowl due to the force of gravity or by means of a built-in pump, which is a special pumping device. The chambers can be sealed off from each other to prevent any risk of cross-contamination.
Features of disc separator from Huading Separator
– Material Quality
All parts which are directly in contact with the product are manufactured in Stainless Steel.
The bowl parts are forged to highest standards and this results in a seamless bowl design and a structure that eliminates micro cracks.
The captured solid particles are discharged at intervals at full operating bowl speed.
In self-cleaning bowl design, full or partial discharges are performed by a hydraulic function that opens and closes the bowl.
– Drive Mechanism
The rotating assembly is driven by an inverter controlled electric motor and a belt or gear driven spindle assembly coupled to the motor. The rotation speed is adjusted through the control panel. Anti-vibration mounts are fitted to the base frame which is bolted to floor to reduce vibration and noise.
The bearings and gears are independently lubricated from a single oil sump.
The lower and upper frames are manufactured by high quality casting. Depending on
the application the frame can also be manufactured with stainless steel cladding.
– Clean in Place (CIP)
The disc separators can be equipped with CIP system as an option.
– Steam-sterilizable design (SIP)
The disc separator in steam-sterilizable design, 137 °C
