Hydraulic pressing is widely used for specialty edible oils because it allows oilseeds and nuts to be processed in controlled batches. The 6YY-400 Hydraulic Oil Press Machine is designed for commercial and industrial oil processing. Its current product page lists a 60 kg batch capacity, a 400 mm barrel diameter, a working pressure of up to 60 MPa and a 3 kW motor. This makes the 6YY-400 Hydraulic Oil Press Machine suitable for businesses that want a larger batch hydraulic press for high-oil-content seeds and specialty products.

What Raw Materials Can It Process?
The machine is suitable for a wide range of oil-rich materials, including:
- Sesame seeds
- Walnuts
- Pine nuts
- Sunflower seeds
- Camellia seeds
- Flaxseed
- Moringa seeds
- Other suitable oil-bearing kernels
The manufacturer describes the machine as suitable for both cold and hot pressing.
How Does Hydraulic Pressing Work?
Hydraulic pressing is different from screw pressing. With a screw press, raw materials continuously move through a pressing chamber. With the 6YY-400 Hydraulic Oil Press Machine, a measured quantity of raw material is loaded into the stainless steel barrel. The hydraulic cylinder then applies pressure evenly to the material. As the pressure increases, oil is gradually released and flows through the filtration gaps. Once the pressing cycle is complete, pressure is released and the remaining cake is removed.
Why Choose a 60 kg Batch Press?
A larger batch capacity can reduce the number of loading cycles required during a working day. For a commercial oil workshop, processing 60 kg per batch can provide a practical balance between batch production and equipment size. This is particularly useful for specialty oils where the producer wants to maintain separate processing batches for different raw materials.
Cold Pressing Applications
Cold pressing is often associated with premium edible oils.
The 6YY-400 Hydraulic Oil Press Machine can be used for products such as:
- Sesame oil
- Walnut oil
- Sunflower oil
- Flaxseed oil
- Camellia oil
- Moringa oil
Temperature should be carefully controlled because the desired processing conditions vary between raw materials.
Hot Pressing Applications
Some oilseeds benefit from controlled heating before pressing. Heating can change the physical characteristics of the material and improve oil release. However, excessive temperature can affect oil quality. Operators should therefore select processing conditions according to the specific crop and final product requirements.
6YY-400 Hydraulic Oil Press Machine for Sesame Oil
Sesame is a high-value specialty oilseed. Before pressing, sesame seeds should be cleaned and prepared properly. The seeds are then loaded into the hydraulic barrel and pressed gradually. The extracted oil may be filtered afterward to remove suspended particles. For premium sesame oil, consistent raw material quality and controlled processing are essential.
6YY-400 Hydraulic Oil Press Machine for Walnut Oil
Walnut oil is another important specialty application. Clean walnut kernels can be loaded into the barrel after suitable preparation. Hydraulic pressure allows the kernels to be compressed gradually, extracting the oil while producing a solid cake. The crude oil should normally be filtered before final storage or packaging.
Hydraulic Oil Press Machine vs. Screw Oil Press Machine
| Feature | 6YY-400 | Screw Oil Press |
|---|---|---|
| Pressing | Hydraulic | Screw |
| Production | Batch | Continuous |
| Batch Size | 60 kg | Continuous feeding |
| Best Application | Specialty oils | Bulk oil production |
| Pressure | Controlled hydraulic pressure | Mechanical compression |
| Workflow | Batch | Continuous |
The choice depends on production goals. Businesses producing specialty oils may prefer hydraulic pressing, while large bulk oil producers often require continuous screw pressing.
Conclusion
The 6YY-400 Hydraulic Oil Press Machine is a heavy-duty batch press designed for commercial and specialty oil production. With a 60 kg batch capacity, 400 mm barrel diameter and pressure of up to 60 MPa, it is suitable for sesame, walnut, sunflower, camellia, flaxseed and other oil-rich materials. It is an option worth considering for businesses that need higher batch capacity without switching to a continuous screw pressing system.
