Definition of screw oil press

Screw press is a kind of edible oil processing equipment that operates on the principle of hydraulic full-automatic, and achieves continuous and highly efficient oil and grease pressing by rotating the screw shaft to propel the material billet. Its core advantage lies in its compact structure, easy operation and high oil yield, which is widely used in the scenarios of individual households, small-scale oil mills and agricultural cooperatives, supporting the pressing of more than 30 kinds of oil crops, such as peanuts, soybeans, rapeseed, oil sunflower and so on.

Technical Principle of Cold Press Oil Extractor

Physically pressed at low temperature to retain natural nutrients

• Cold Press Oil Extractor adopts pure physical pressing method, applying pressure to the oil material through screw extrusion or hydraulic propulsion, so that the oil and grease can be separated from the oil material.
• Low temperature control: The pressing temperature is usually controlled below 60℃ (some models can be as low as 65℃) to avoid high temperature destroying the unsaturated fatty acids, vitamin E, sterols and other active ingredients in the oil.
• No chemical additives: No chemical solvents or additives are added throughout the process, ensuring that the oils are pure and natural.
• Multi-stage pressing: Some models (screw presses) are designed with multi-stage compression and expansion to increase the oil yield and reduce the residual oil rate.

Advantageous features of the oil press

• Nutritional retention intact: low temperature pressing technology maximizes the retention of the natural flavor and nutrients in the oil.
• For example: omega-3 fatty acids in flaxseed oil; brain gold (DHA) precursors in walnut oil; alpha-linolenic acid in perilla seed oil
• Enhanced oil yield: Cold pressing technology can yield up to 93% of oil, and the residual oil rate of dry cake is as low as 5%, which is much higher than the traditional hot pressing process.
• It supports the processing of more than 18 kinds of oilseeds such as peanuts, sesame seeds, walnuts, flaxseeds, perilla seeds, tea seeds, etc. It can also handle industrial oilseeds such as cottonseeds and rice bran.

Oil presses for sale: configuration recommendations

A complete set of oil extraction equipment usually includes three core equipments: main machine of oil press, frying pot and oil filter, and auxiliary equipments such as feeding machine, shelling machine, embryo press, oil storage tank and filling machine can be selected according to the demand, so as to realize the whole process automation from raw material pre-treatment to finished oil filling.

• Small oil mill (daily processing <500kg)
• Core equipment: 6YL-80/100 screw oil press, electric frying pan, centrifugal oil filter.
• Auxiliary equipment: loading machine, peanut shelling machine (if needed to handle raw materials with shells).
• Medium-sized oil plant (500-2000kg per day)
• Core equipment: 6YL-120/160 screw oil press, drum type fryer, plate and frame oil filter.
• Auxiliary equipment: automatic loading machine, embryo press, oil storage tank.
• Large-scale production line (daily processing >2000kg)
• Core equipment: automatic oil press production line +, refining equipment (degumming, deacidification, decolorization).
• Configuration: multi-stage pressing system, PLC control system, low temperature crystallization and crystal raising tank.

What kind of oil is suitable for cold pressed oil press machine

• Flaxseed: The oil is famous for its very high content of Omega-3 fatty acids. It is sold as a dietary supplement.
• Walnuts and Almonds: These nuts produce delicious gourmet oils that are used for finishing dishes and in salad dressings. Their nutty flavor is the main selling point.
• Perilla Seed: This is popular in Asian cuisine and is also known for its health benefits.
• Sesame Seed: Cold pressed sesame oil has a lighter color and a more delicate flavor than the toasted version. It is used in different types of cuisine.
• Avocado: Cold pressed avocado oil is a very popular, high-value product in the health food market.

Why is Cold Pressed Oil a Premium Product?

Cold pressed oil is a premium product because it offers superior flavor, aroma, and nutritional value. Customers are willing to pay a much higher price for these benefits. For your business, this means higher profit margins. The gentle extraction of a cold press oil expeller ensures that the final oil is as close to its natural state as possible. This is a powerful selling point in today’s health-conscious market.

The main benefit is the preservation of nutrients. Many valuable seeds contain delicate compounds like omega-3 fatty acids, antioxidants, and vitamins. Heat destroys these. Cold pressing keeps them intact. This allows you to market your oil as a health food or supplement. The flavor and aroma are also much better. Think about the rich, nutty taste of fresh walnut oil or the distinct scent of flaxseed oil. Cold pressing captures these perfectly. Hot pressing would bake these delicate flavors away, leaving a more generic taste. By producing cold pressed oil, you are not just selling a cooking ingredient. You are selling a gourmet experience and a health product.

Application and Economic Prospects of Oil Press Equipment

The market for cold pressed oils is growing, and the technology is improving. As we look towards 2025, we see a clear trend. More consumers are looking for clean, unprocessed foods. This is driving demand for a wider variety of cold pressed oils. Businesses are now exploring new seeds and nuts to create unique, niche products.

The technology for the cold press oil expeller is also advancing. We are seeing more automation being integrated into these machines. New models may have automatic systems for loading the seeds and unloading the cake. This reduces manual labor and improves efficiency for small businesses. Digital control panels are also becoming more common.

These allow for even more precise control over the pressing cycle. This helps you to create a perfectly consistent product every single time. Another growing area is the use of cold pressed oils in the cosmetics industry. This opens up a completely new and profitable market for your oil.
