The characteristics of screw press oil machine

Screw oil press is a kind of edible oil processing equipment that operates on the principle of hydraulic full-automatic, and it pushes the material billet through the rotation of the screw shaft to realize continuous and efficient oil and grease pressing. 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, canola, sunflower, avocado and so on.

Technical principle of avocado oil press machine

The nutritional value of avocado oil (such as monounsaturated fatty acids, vitamin E) is sensitive to temperature, and high temperature is easy to destroy its active ingredients. Therefore, the mainstream oil press adopts low-temperature cold pressing technology, which directly squeezes the fruit pulp through mechanical pressure, and controls the temperature between 40-60℃ to maximize the retention of the natural flavor and nutrients of the oil.

Some equipments combine with solvent extraction process, first cold pressing and then extracting the residual oil with ethyl acetate and other solvents to further improve the oil yield, but need to be followed by refining to remove solvent residues.

What kind of oil can be extracted from the oil press?

Oil presses (especially screw presses) are capable of pressing a wide range of oil crops and oil-bearing seeds due to their high efficiency and multi-functionality, covering agricultural, food processing and industrial fields.

Soybean: oil yield is about 12%-18%, and the crushed soybean cake can be used as feed or protein raw material.
Canola (rapeseed): oil yield 30%-45%, is the main source of rapeseed oil.
Peanut: oil yield 40%-50%, peanut oil has strong aroma and high market value.
Cottonseed: oil yield 10%-20%, need to be pressed after detoxification treatment, cottonseed oil can be used for industry or food.
Sunflower seeds (sunflower): oil yield 25%-40%, sunflower oil is rich in unsaturated fatty acids.
Castor seed: oil yield 40%-50%, castor oil is an important raw material for aviation lubricants and plastic plasticizers.
Tung oil: extracted from the seeds of the tung oil tree, used in wood preservation or paint industry.
Sapium sebiferum seed: 30%-40% oil yield, Sapium sebiferum oil can be used to make soap, candles or biodiesel.

Product Advantages of Strip Row Oil Press

Effectively increase the oil yield
Professional equipment by optimizing the press chamber structure (such as screw extrusion, hydraulic pressurization) and pressure parameters (up to 315 tons), so that the avocado oil yield is increased to 50%-60%, much higher than the traditional hot pressing method.
Oil purity
Low temperature pressing to avoid oxidation and rancidity of oil, together with multi-stage filtration system (e.g. rotary evaporation, vacuum degassing), it can produce extra virgin avocado oil (with bright green color and strong smell), which meets the standard of cosmetic grade.
Multifunctional Adaptable
Avocado oil press machine is usually compatible with a variety of oil crops (such as walnuts, almonds, tea seeds), one machine can be used for multiple purposes to reduce the cost of equipment.

Application Scenarios of Oil Press: From Home Workshop to Industrial Production

Families/small workshops
choose portable screw oil press (e.g. Model 6YL-120A) with 11-15kW power and processing capacity of 200-300kg/day to meet the needs of personalized customization. The equipment is easy to operate, one person can complete the whole process of cleaning, de-kerneling and pressing.
Commercial Processing Plant
It needs to be equipped with automatic production line, including washing machine, peeling and de-kerneling machine, low-temperature dryer, multi-stage press and refining equipment. For example: 200kg-50ton/day production line, through the cold pressing + extraction + low temperature separation process, to realize the large-scale production of avocado oil, products exported to Europe and the United States market.
Cosmetics/Nutraceuticals Company
The high purity requirements of the oil require molecular distillation equipment to remove phospholipids and other gums. The refined avocado oil is light yellow in color, with an extended shelf life of 18-24 months, and is suitable for high-end skin care formulations.
