11.7/8 Inch Taper Cage Bar Oil Expeller

A Taper Cage Bar Oil Expeller is a specialized type of mechanical oil extraction equipment used to extract oil from oilseeds, nuts, or oil-rich crops. This type of expeller is characterized by a unique cage design with tapered bars that gradually reduce in size along the length of the cage. This design provides efficient compression and oil extraction. Here’s a description of the key components and the operation of a Taper Cage Bar Oil Expeller:

• Hopper: Similar to other oil expellers, the raw material (such as oilseeds or nuts) is loaded into a hopper that feeds it into the expeller chamber.
• Expeller Chamber: The expeller chamber in a Taper Cage Bar Oil Expeller is a cylindrical enclosure where oil extraction takes place. It contains the tapered cage bars and a rotating shaft.
• Tapered Cage Bars: The distinctive feature of this expeller is the presence of tapered cage bars. These bars gradually reduce in size along the length of the cage. The tapering helps in increasing the pressure on the material as it progresses through the chamber.
• Cage: The cage, made up of the tapered bars, surrounds the rotating shaft. It contains perforations or openings that allow the oil to flow out while keeping the solid material contained within the chamber.
• Pressure Adjustment: Some Taper Cage Bar Oil Expellers have an adjustable pressure mechanism, allowing operators to control the pressure applied to the material. This adjustment helps optimize oil extraction efficiency.
• Drive Mechanism: The rotating shaft is connected to a motor or an external power source, which rotates it at a controlled speed. The rotation of the shaft facilitates the movement of the material through the cage.
• Oil Outlet: As the material moves through the tapered cage bars, it is subjected to increasing pressure. This pressure causes the oil to be released from the oil-bearing cells. The oil flows through the perforations in the cage and collects in a receptacle or trough at the bottom of the expeller.
• Residue Outlet: The solid residue, known as the cake, exits the expeller through a separate outlet. This cake can be used as animal feed or further processed for various applications.
• Heating: In some instances, Taper Cage Bar Oil Expellers may include a heating component to reduce the viscosity of the oil and improve extraction efficiency, especially when processing materials with high oil content.

The operation of a Taper Cage Bar Oil Expeller involves continuously feeding the raw material into the hopper, which is then compressed and subjected to increasing pressure as it moves through the tapered cage bars. This mechanical action breaks down the oil-bearing cells and releases the oil, which flows through the perforations in the cage and is collected. The remaining solid cake is expelled through a separate outlet.

Taper Cage Bar Oil Expellers are designed for efficient oil extraction and are often used in medium to large-scale oil processing operations. Their unique cage bar design allows for higher oil extraction rates compared to some other expeller types, making them suitable for a wide range of oilseeds and oil-rich crops.
