38 Teeth Bevel Gear Oil Expeller

A Bevel Oil Expeller, also known as a Bevel Gear Oil Expeller, is a type of mechanical oil extraction machine used for extracting oil from various oilseeds, nuts, or oil-rich crops. This type of expeller is characterized by the use of bevel gears to transmit power from the motor to the expeller shaft, which, in turn, exerts mechanical pressure on the oil-bearing material to extract the oil. Here’s a description of the key components and the operation of a Bevel Oil Expeller:

• Hopper: 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 is a cylindrical or conical enclosure where the oil extraction process takes place. It contains the central expeller shaft, bevel gears, and other components.
• Central Expeller Shaft: The central expeller shaft is a key component of the expeller. It is typically a cylindrical shaft that extends through the expeller chamber. The shaft is equipped with bevel gears that transmit power from the motor to the shaft.
• Bevel Gears: Bevel gears are used to transmit rotational power from the motor to the expeller shaft at an angle. These gears are responsible for the mechanical action of the expeller. As the motor turns, the bevel gears engage and rotate the expeller shaft.
• Pressure Adjustment: Some Bevel Oil Expellers have adjustable pressure mechanisms that allow operators to control the level of pressure applied to the material. This is important for optimizing oil extraction efficiency.
• Drive Mechanism: The central expeller shaft is connected to a motor or an external power source, which rotates it at a controlled speed. The rotation of the shaft is what drives the movement of the material through the expeller.
• Oil Outlet: As the material is compressed and subjected to pressure due to the rotating expeller shaft, oil is released from the oil-bearing cells. The oil flows out through an outlet and is collected in a receptacle or trough.
• 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 purposes.
• Heating: In some cases, Bevel 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 Bevel Oil Expeller involves continuously feeding the raw material into the hopper. As the material moves through the expeller chamber, it is subjected to mechanical pressure due to the rotating expeller shaft driven by the bevel gears. This pressure causes the oil to be released from the oil-bearing cells, and the oil flows out through an outlet, while the solid cake is expelled through a separate outlet.

Bevel Oil Expellers are suitable for processing a variety of oilseeds and oil-rich crops, including but not limited to soybeans, sunflower seeds, peanuts, and more. They are commonly used in small to medium-scale oil extraction operations due to their simplicity, efficiency, and versatility in handling various oilseed types.
