Introduction A decanter centrifuge is an industrial machine that separates solids from liquids (or two immiscible liquids) using high-speed rotational force. Widely used in wastewater treatment, food processing, and oil drilling, it operates continuously. How Does a Decanter Centrifuge Work? The working principle of a decanter centrifuge is to achieve solid-liquid separation through centrifugal force generated by high-speed rotation. The slurry to be processed enters the rotating bowl (typically at 1,500 to 4,000 RPM) through a central feed pipe. Under the effect of centrifugal force, the heavier solid particles quickly move outward and settle along the bowl wall, forming an outer layer, while the less dense liquid forms an inner layer. At the same time, a scroll conveyor rotates at a slightly slower speed (5 to 20 RPM less than the bowl) to continuously transport the settled solids toward the conical end of the bowl for discharge. The clarified liquid is discharged through adjustable weirs, enabling continuous solid-liquid separation. Different Types of Decanter Centrifuges  Decanter centrifuges come in several types, each designed to suit specific applications and material properties. Here are the main types: Two-Phase Decanter Centrifuge The two-phase decanter centrifuge is designed for separating solid particles from liquids in mixtures where the composition includes a distinct solid-liquid ratio and a uniform liquid phase. In operation, the material flows into a horizontally oriented drum that spins at high speed. Due to the centrifugal force generated, the denser solid particles are driven outward to the inner wall of the drum, while the lighter liquid remains closer to the center. A helical screw conveyor, rotating at a slightly reduced speed compared to the drum, steadily transports the accumulated solids toward the conical end for removal. At the same time, the clarified liquid exits continuously from the opposite end via adjustable weir plates. This type of centrifuge is widely applied in fields such as municipal sludge treatment, industrial wastewater processing, food industry separation tasks (e.g., removing solids from soy milk), and the handling of drilling fluids in the energy sector. Three-Phase Decanter Centrifuge The three-phase decanter centrifuge is designed to simultaneously separate solids and two immiscible liquid phases—commonly oil and water—from complex mixtures that contain fat, oil, or emulsified substances. When the feed material enters the high-speed rotating drum, centrifugal force causes the components to separate based on their densities. The heaviest solid particles move outward and settle against the drum wall. Just inside this layer, the denser liquid (typically water) forms a middle layer, while the lightest liquid (such as oil) forms the innermost layer near the rotation axis. A scroll conveyor rotating slightly slower than the drum transports the solid fraction to the conical end for discharge. Meanwhile, the two liquid layers are directed to separate outlets or adjustable weirs positioned at different radial levels, allowing for independent and continuous extraction of each phase. This type of centrifuge is widely used in sectors such as food processing (e.g., vegetable oil or animal fat extraction), meat by-product recovery, oil-water-solid separation in the petroleum and energy industries, and in the treatment of complex industrial waste liquids like emulsions. Decanter Centrifuge Applications Decanter centrifuges are widely used across various industries due to their ability to continuously and efficiently separate solids from liquids. In the environmental sector, they are essential for municipal and industrial wastewater treatment, particularly in sludge dewatering. In the oil and gas industry, they are used to treat drilling mud and separate oil, water, and solids. The food and beverage industry relies on them for applications such as juice clarification, soy milk residue separation, and the extraction of vegetable oils and animal fats. In meat processing and by-product recovery, decanter centrifuges help separate solids, fats, and water, improving resource utilization. They are also employed in the chemical and pharmaceutical industries for separating crystallized compounds, recovering reaction products, and purifying solutions. In mining and metallurgy, these machines are used for tailings management, dewatering slurry, and recovering valuable minerals. Additionally, in the pulp and textile industries, decanter centrifuges assist in reclaiming fibers and removing solids from process water. ​Their versatility, automation, and high throughput make them an indispensable solution for solid-liquid separation across a wide range of industrial processes.

For better understand our structure of the  hemp/plant oil extraction centrifuge,pls see the below pics.   warmly welcome you to come to visit and cooperate          

Peony developed a new stype PPTD centrifuge ,specialized in hemp oil extraction,plant oil extraction,cannabis oil with ethanol soap. Characteristics:   ·304 and 316L Sanitary Stainless Steel Construction ·Low temperature rating: -40c ·Reinforced Sight Glass ·Bi-Directional Agitation ·Auto/Manual Controls ·Digital HMI Interface ·Variable Speed Control ·Easy Material Loading/Unloading ·Heavy-Duty Spin Drying ·No foundation required     Operator fills filter bag with milled plant material and places it in the machine. The centrifuge is then flooded, and bi-directionally agitated for full target compound removal. After the wash, the plant material undergoes a medium duty spin dry till high speed spin dry to remove the liquid as much as possible. The alcohol wash is then collected to some container for further processing System loading: A pre-loaded closed filter bag is placed into the basket Program Menu: The “Spray Wash” or “Agitation Wash” program is selected on the HMI where the RPM and cycle times are set to the operator’s specifications. Fill: Alcohol is connected from source tank into the centrifuge. The Wash cycle: The plant material undergoes an agitated wash with a set number of bi-directional agitations System Draining: When the wash cycle is complete, the outlet valve is manually opened and the liquid drained. The alcohol wash is pumped to a properly rated storage reservoir for further processing. Spin Dry Cycle: The “Spin Dry” menu is selected on the HMI and the drying cycle is started.
