We offer four types of screw oil press machines to cater to diverse user needs: semi-automatic, fully automatic, cold and hot press, and hydraulic press. With a processing capacity ranging from 40 to 350 kg/h, these machines are designed to deliver exceptional performance and efficiency.
Our oil press machines are not limited to traditional materials like peanuts; they can also efficiently extract oil from sesame, soybeans, rapeseed, and many other oilseeds. Featuring high efficiency, energy savings, user-friendly operation, and excellent production capacity, these machines are the ideal choice for the oilseed processing industry.
Screw oil press machine working process
What materials are suitable for oil extraction machine?
- Sunflower seeds. Sunflower seeds contain a significant amount of oil and are commonly used for oil extraction. Sunflower oil is known for its light flavor and high smoke point, making it suitable for frying and cooking.
- Rapeseeds (Canola). Rapeseeds, which are also known as canola seeds, are widely used for oil extraction. Canola oil is low in saturated fat and has a neutral flavor, making it suitable for various culinary applications.
- Peanuts (Groundnuts). Peanuts are rich in oil and are commonly used for oil extraction. Peanut oil has a distinctive flavor and is often used in Asian cuisines.
- Sesame seeds. Sesame seeds are known for their high oil content and are commonly used for oil extraction. Sesame oil is prized for its nutty flavor and is used in various cuisines worldwide.
Type 1: Hydraulic oil press machine
Working principle:
The hydraulic oil press machine uses liquid as the medium for pressure transmission, generating working pressure to squeeze oil into the cake ring.
Model options:
- We offer four models to meet varying capacity needs.
- Popular models: 6YZ-180, 6YZ-230, and 6YZ-260.
- Powered by a motor for efficient operation.
Enhanced oil quality:
A separator is used during material placement to ensure thorough squeezing.
Results in:
- Fewer impurities in the final oil.
- Superior oil quality.
- High cake value for secondary use.
Structure of sesame oil press machine
Key components: upper top plate, distribution box, pressure gauge, base, reinforcement ring, material barrel, oil receiving plate, oil cylinder, plunger.
Features:
- compact structure
- attractive and modern design
- space-saving with a small footprint
- optimized for effective sesame oil extraction
Automatic hydraulic oil press machine’s working flow
- Preheating:
- Before each oil extraction, preheat the machine.
- Summer and autumn: 70-80°C
- Winter and spring: 80-100°C
- Before each oil extraction, preheat the machine.
- Machine preparation:
- Run the machine 1-2 times before oil extraction for 5-10 minutes with air to thin the hydraulic oil, ensuring smooth operation.
- Oil extraction process:
- Place the fried oilseeds into the press chamber.
- When the oil level is slightly below the upper-end face, add the separator.
- During the boosting process, ensure the machine is monitored at all times.
- Once no oil seeps from the pressing chamber’s oil joint, the extraction is complete.
- Completion:
- Turn off the machine and remove the oil cake.

Type 3: Screw oil press machine for peanut
Oil pressing mechanism:
- Similar to Type 2, the pressing part is designed for efficient oil extraction from peanuts.
Added feature:
- Equipped with a screw feeder that enables material circulation.
Cold pressing advantages:
- Nutrients in the oil are preserved without being destroyed.
- Cake can be pressed multiple times due to the lower oil yield.
Oil characteristics:
- Hot-pressed oil has a darker color.
- Cold-pressed oil has a lighter color.
Power source:
- Operated by a motor for reliable performance.

Type 4: Semi-automatic screw oil press machine
The semi-automatic screw oil press machine has not any other accessories. It only has the part that can extract oil. The structure and operation of the machine are also simpler.
The power of this semi-automatic oil press can be an electric motor and a diesel engine. Customers can choose the power according to their own needs. So, machines of this model are also more affordable.
What is the structure of single screw oil press machine?
The core structure of Type 2 and Type 4 is similar, including material inlet, adjustment section, heating element, press part, oil out part, power(motor, diesel engine), etc.
Two sets of oil expellers sold to Angola
Last week we had a customer from Angola. He wants to start an oil pressing project. And through Alibaba, he gets our contact information and sends an inquiry to us.
This customer wants to press Soybean oil. Also, according to his need for output, we recommend the ZY-150 model to him. Finally, he bought two sets of oil press machines.
