Oil extraction machine

Oil extraction machines can extract various kinds of grains oil. It can produce 7-23 kg (raw material) per hour, which the machine is made of good stainless steel and durable which is especially suitable for extracting vegetable oils. The products that customers prefer to extract oil include soybeans, black sesame, peanut, sunflower, etc.

Oil extraction machines typically use a screw press. Some products, like groundnuts, need to be shelled or peeled before moving through the screw press. The peeling process might use powerful centrifugal forces or airflow from a fan to separate lightweight shells from the heavier nut.

Oil extraction machines can come in several configurations, but here are some of the main components you’ll typically find:

• Hopper: The hopper is a metal structure that funnels the raw material into the screw press.
• Screw press: The screw press is the powerhouse of the oil expeller. The screw shaft rotates within a cylindrical cage, pushing the material forward in a high-pressure chamber. Friction is generated between the material, the screw shaft, the feedstock and the press chamber itself.
• Gear reduction unit: The gear reduction unit, or gearbox, converts the speed and torque of the electric motor to the right settings for the machine.
• Slots or screens: A screening surface allows oils to seep out while keeping the leftover materials moving through the screw, where they press into a “cake” for removal.
• Frame: The metal frame provides the support for and connects these components.

You’ll find various other parts in an oil extraction machine like lock nuts, rings, seals and gaskets that make up these larger components and link them together. These parts might be made of metals and elastomeric materials, both of which offer long-lasting durability in the tough, messy conditions of oil pressing.
