High-quality hydraulic oil pressing machine

The hydraulic oil pressing machine is a device that utilizes a high-pressure hydraulic system to physically extract oil from oil-bearing materials. It is suitable for processing over 30 types of crops, including peanuts, soybeans, sesame seeds, rapeseed, flaxseed, tea seeds, sunflower seeds, walnuts, and moringa seeds.

Taizy oil press machine is driven by an ultra-high-pressure hydraulic pump station. The equipment operates at pressures up to 50 MPa and offers a processing capacity of 90–110 L/h. It is characterized by a high oil yield, pure oil quality, low energy consumption, and ease of operation.

What are the key advantages of hydraulic oil presses?

The reason this large-scale hydraulic oil pressing machine is being chosen by an increasing number of users is primarily that its overall performance is better suited to a “high-profit oil extraction model.”

1. Higher oil yield, directly increasing profits

This peanut oil expeller machine utilizes a progressive high-pressure method to ensure the complete extraction of oil from the raw material.

• Compared to traditional equipment, this machine can increase the peanut oil yield by approximately 2% to 5%.
• It produces an additional 1–2.5kg of peanut oil for every 50 catties of peanuts processed.
• Long-term processing returns are significantly increased.

For users with high daily processing volumes, this advantage translates directly into substantial profit growth.

2. The oil is cleaner, with virtually no impurities

Hydraulic pressing is a purely physical extraction process that avoids high-temperature, destructive treatment.

• The oil is clear and bright.
• There is minimal sediment.
• It is free from chemical residues.
• It retains its natural aroma.

The extracted oil can essentially be sold after simple settling, making it particularly suitable for the premium edible oil market.

3. Low energy consumption, saves on electricity costs

The hydraulic system of our hydraulic oil pressing machine utilizes an intermittent pressurization method, eliminating the need for continuous high-power operation.

• Hourly power consumption is approximately 0.5–1kw/h.
• It offers energy savings of around 40% compared to screw-type oil presses.
• It significantly reduces daily electricity costs.

It is suitable for oil mills or processing facilities requiring long-term, continuous operation.

4. Simple operation, production can be handled by 1–2 people

The hydraulic oil press machine utilizes an automatic hydraulic control system.

• It features automatic pressurization, pressure holding, and pressure release.
• Operators can step away from the machine during operation.
• It reduces reliance on manual labor.

This peanut oil press is highly suitable for rural oil mills and entrepreneurs.

How does the hydraulic oil pressing machine work?

Our oil press utilizes a hydraulic pump station to generate high-pressure fluid, driving the hydraulic cylinder piston downward to vertically compress the oil-bearing material.

The process is as follows:

Loading → Hydraulic pressurization → High-pressure pressing → Oil extraction → Sustained pressure for oil yield → Pressure release and cake removal.

The entire process maintains uniform and sustained pressure, resulting in a higher oil yield.

Models and key specifications of hydraulic oil presses

6YY-280D	110L/H	3KW	≤50MPa	250T	380V	2350KG

Note: The models above are our hot-selling hydraulic oil press machines. We also offer larger-capacity models for higher production needs.

What raw materials can hydraulic oil press process?

Many customers look for equipment capable of processing a variety of raw materials. Our hydraulic oil pressing machine is a prime example of a versatile, multi-purpose machine.

Commonly processed raw materials include:

• ピーナッツ
• Sesame seeds
• Soybeans
• 菜種
• Flaxseed
• Tea seeds
• Sunflower seeds
• Walnuts
• Moringa seeds
• 綿実
• アーモンド

In addition to oil extraction, the hydraulic oil pressing machine can also be used for:

• Fruit and vegetable juice extraction
• Dewatering of traditional Chinese medicinal herbs
• Pressing of chemical raw materials
• Oil removal from oil cake/residue

Consequently, many food processing plants and agricultural processing enterprises choose the hydraulic oil press as an auxiliary piece of equipment.

Why does the hydraulic oil press have a higher oil yield?

For the oil extraction industry, the oil yield directly determines the final profit. Traditional equipment often leaves a significant amount of residual oil in the oil cake after pressing; in contrast, the hydraulic oil pressing machine utilizes sustained high pressure to extract more oil, typically resulting in a higher yield.

Taking peanuts as an example:

• Standard equipment yields approximately 40%–43%.
• Hydraulic oil presses can achieve yields of 43%–48%.

For users processing hundreds of kilograms or even tons of raw material daily, the revenue generated by this increased output is substantial.

Hydraulic oil press vs screw oil press

アイテム	油圧オイルプレス	ねじ油圧プレス
Pressing method	High-pressure hydraulic pressing	Mechanical screw pressing
Working process	Batch pressing	Continuous pressing
Oil quality	Clear oil with fewer impurities	Requires further filtration
Oil aroma	Better retains natural flavor and aroma	Flavor may be affected by friction and heat
油収率	Higher oil extraction rate	Stable oil extraction rate
適切な材料	Peanut, sesame, walnut, tea seed, flaxseed, sunflower seed	Soybean, rapeseed, cottonseed, corn germ, rice bran
Finished oil	High-quality cold-pressed oil	Suitable for further refining

For high-value oils such as peanut oil, sesame oil, walnut oil, and tea seed oil, a hydraulic oil pressing machine is often the preferred choice because it produces cleaner oil, better aroma, and higher oil yield. For soybean, rapeseed, and other bulk oil crops, a screw oil press is more commonly used in large-scale oil production.

What is the price of a hydraulic oil expeller?

The price of a hydraulic oil press is not fixed but is influenced by various factors:

• Model and production capacity
• Pressure rating
• Level of automation
• Motor configuration
• Export voltage requirements
• Shipping distance and transport policies
