The seals and rubber materials of the ultra-clean centrifuge are FDA food-grade certified.

The hygienic requirements for foodstuffs, pharmaceuticals, fine chemicals and biologicals are very high compared to other materials, and in particular one of the main areas of application of the FOOD Hygienic grade - food processing OUPENG Machinery has always designed and manufactured its centrifuges in accordance with Hygienic by Design standards. In the food industry sector, all components that come into contact with the product must be able to be CIP (cleaned in place) and are therefore specifically designed for automatic cleaning.

Used to meet the requirements for safe handling of food, pharmaceutical, fine chemical and biotechnology products.

Decanter centrifuges are used when separating solid-liquid mixtures with a high solids content. This decanter centrifuge, unlike a chamber filter press, is capable of continuous operation. The powerful centrifugal force enables the separation of fine solid particles from suspensions with different densities.

The modular construction allows our decanter centrifuges to be used in all types of industries worldwide. These centrifuges are perfectly suited for a wide range of applications. They are used in a wide range of processes, from sludge dewatering through sorting and moisture classification to solids sorting.

China OUPENG MACHINERY FOOD sanitary decanter centrifuge unites our more than 30 years of experience and expertise in the food field. In order to achieve optimum separation, decanter centrifuges should be specially designed for specific separation requirements.

China oupeng machinery FOOD food grade decanter centrifuge working principle   

A decanter centrifuge can be thought of as a settling tank rotating around its axis. In a settling tank, solid particles heavier than the liquid sink to the bottom by gravity and form a precipitate (solid phase) at the bottom of the tank. For example, a decanter centrifuge used for the production of soymilk can be understood as a settling tank. In a centrifuge, the separation of the solid and liquid phases is achieved by centrifugal acceleration. In the self-rotating centrifuge rotor, the solid particles, which are denser and heavier than the liquid, move outward with the aid of centrifugal force. They form a sediment on the inner wall of the rotor. In a centrifuge, a centrifugal force of about 4,000 g is generated, compared to only 1 g in a gravitational field, so that solid particles are separated from liquids faster and more efficiently.

Decanter centrifuge feed   

The material is introduced into the inlet area of the decanter centrifuge screw conveyor via a centrally arranged feed tube. Here, after gentle pre-acceleration, the material passes through the opening of the separator into the decanter centrifuge drum.

Decanter centrifuge drum   

The decanter centrifuge drum is cylindrical plus conical in shape and rotates at a speed suitable for the separation task. The material rotates with the centrifuge drum and forms a concentric liquid layer on the inner wall of the drum. Under the action of centrifugal force, the solid particles contained within the material settle to the inner wall of the drum due to their higher density. The length of the cylindrical rotor and the cone angle of the cone can be adjusted in the manufacture of the decanter centrifuge according to the user's needs for processing materials.

Decanter centrifuge screw pusher   

The decanter screw conveyor rotates at a speed slightly different from the drum speed and continuously pushes the settled solids towards the conical end of the drum. The differential speed determines the residence time of the solids in the drum of the decanter centrifuge, which is an important parameter in determining the dry solids content. Optimum separation can be achieved by varying the differential speed of the screw conveyor. Depending on the application and the task, the design of the screw conveyor varies.

Solid phase discharge port   

The separated solids are discharged through a discharge hole in the cone end of the drum into a solids aggregate hood and downward.

Liquid level adjusting plate   

The clarified liquid (liquid phase) flows to the conical end of the drum and is discharged out of the machine through an opening in the drum cover. An easily adjustable and highly accurate weir plate (level adjusting plate) makes it possible to accurately adjust the depth of the liquid layer in the drum (liquid pool depth). The overflow is discharged into a collecting pipe and is discharged from the machine by gravity.
