Not every oil processing business wants to use a continuous screw expeller. For specialty edible oils, cold pressing and careful processing can be more important than maximum hourly throughput.
The 6YZ-360 Hydraulic Oil Press Machine is designed around vertical hydraulic pressing. OilPressStore describes it as a high-pressure cold press system with a 22.5 kg pressing barrel, up to 60 MPa hydraulic pressure and a production capacity of up to approximately 90 kg/h.
The machine is particularly suitable for businesses producing specialty oils where aroma, flavor and nutritional characteristics are important.
What Is a Hydraulic Oil Press?
A hydraulic oil press uses hydraulic pressure rather than a continuously rotating screw to extract oil.
Raw material is placed into a pressing barrel. A hydraulic cylinder then applies pressure to the material, gradually squeezing the oil from the oil-bearing seeds or nuts.
Compared with continuous screw pressing, hydraulic pressing is generally more suitable for batch production.
Suitable Raw Materials
The 6YZ-360 Hydraulic Oil Press Machine is designed for a variety of high-oil-content seeds and nuts.
The current product page lists:
- Sesame seeds
- Walnuts
- Sunflower seeds
- Pine nuts
- Almonds
- Flaxseeds
- Camellia seeds
- Perilla seeds
- Mustard seeds
The machine is especially suitable for specialty oil production where the natural aroma and characteristics of the raw material are important.
How Does the 6YZ-360 Hydraulic Oil Press Machine Work?
The operation begins by loading prepared raw material into the stainless steel pressing barrel.
The hydraulic system then applies vertical pressure to the material. According to the product information, the hydraulic system can generate pressure up to 60 MPa.
As pressure increases, oil is released from the material and collected below the pressing barrel.
The process is performed in batches rather than through continuous screw feeding.
Why Use Hydraulic Cold Pressing?
Controlled Pressing
Hydraulic pressing allows pressure to be applied progressively to the raw material.
Suitable for Specialty Oils
Certain premium oils are marketed based on their natural flavor, aroma and processing characteristics.
Low Mechanical Friction
Unlike a screw expeller, hydraulic pressing does not continuously force the material through a screw cage.
Quiet Operation
The current product description emphasizes low noise and low vibration operation.
Food-Grade Construction
The 6YZ-360 Hydraulic Oil Press Machine uses a stainless steel pressing barrel designed for food-related applications.
Cold Pressing and Oil Quality
Cold pressing is often associated with specialty edible oils because the process can reduce excessive heating during extraction.
However, “cold pressed” does not mean that temperature has no effect at all. Raw material temperature, ambient conditions and any preheating process can influence the final product.
The 6YZ-360 Hydraulic Oil Press Machine includes a 1250 W pre-heating system, which can be used to condition the barrel according to the processing requirements.
For businesses producing premium oils, temperature management should therefore be treated as part of the overall production process.
6YZ-360 Hydraulic Oil Press Machine for Walnut and Specialty Oil
Walnut oil is one example of a specialty product that can benefit from controlled pressing.
The raw material should be properly cleaned and prepared before entering the barrel.
After pressing, the crude oil may contain suspended particles and should be filtered according to the required final product standard.
Similar principles can be applied to sesame, flaxseed, camellia seed and other specialty oils.
How to Operate the Hydraulic Oil Press Machine?
A typical workflow is:
Prepare Seeds → Load Barrel → Set Suitable Temperature → Apply Hydraulic Pressure → Collect Oil → Remove Cake → Filter Oil
The operator should avoid overloading the pressing barrel.
The current product information specifies a 22.5 kg pressing barrel, which provides a useful reference for batch operation.
Who Should Choose the 6YZ-360 Hydraulic Oil Press Machine?
The machine can be considered by:
- Specialty edible oil producers
- Health food businesses
- Organic food stores
- Small and medium oil workshops
- Agricultural cooperatives
- Premium oil brands
- Businesses selling freshly pressed oil
It is especially useful where product positioning emphasizes specialty oils rather than maximum bulk production.
Hydraulic Oil Press Machine vs. Screw Oil Press Machine
A screw oil press is generally better suited to continuous high-throughput production.
A hydraulic press is more suitable for batch pressing and specialty products.
Therefore, buyers should choose according to their business model.
If the main goal is processing several tons of common oilseeds every day, a continuous screw press may be more appropriate.
If the goal is producing smaller quantities of specialty oils with controlled batch processing, a hydraulic press such as the 6YZ-360 may be more suitable.
Conclusion
The 6YZ-360 Hydraulic Oil Press Machine is a high-pressure batch cold press designed for specialty and edible oil production.
With a 22.5 kg pressing barrel, up to 60 MPa hydraulic pressure and approximately 90 kg/h production capacity, it provides a different production approach from conventional screw oil presses.
For businesses producing sesame, walnut, sunflower, flaxseed, camellia and other specialty oils, the 6YZ-360 Hydraulic Oil Press Machine can be a practical solution when controlled hydraulic pressing is preferred.
