Small oil factory production line

Around the world, the consumption of edible oils is growing by the day. You have probably noticed that the demand for different types of oils is also increasing as people have differing tastes and uses of the same. What you may not know is that such oils are produced from a variety of simple seeds and nuts such as soya, coconut, maize, sunflower, ground nuts, macadamia seed, sesame seed and mustard seed to name a few. So, how is oilseed extracted and processed?

Preparations Before Starting an Oil Press Factory

With the growing popularity of healthy eating concepts, demand in the edible oil market continues to rise, making the establishment of a food oil processing plant an attractive choice for many entrepreneurs. Among the equipment, the screw oil press has become the core machinery for small and medium-sized oil mills due to its high efficiency, energy savings, and user-friendly operation.

• Analyze local cooking oil consumption habits (such as preferences for rapeseed oil, nut oils, coconut oil, etc.) to determine the primary product types.
• Assess the stability of oilseed supply and establish long-term partnerships with farmers or suppliers.
• Adequate water and electricity: Ensure stable power supply (it is recommended to have a backup generator) and access to clean water sources.
• Convenient transportation: Proximity to raw material sources or transportation hubs reduces shipping costs.
• Factory Layout: Prepare raw material storage areas with moisture-proof and pest-proof features, equipped with ventilation systems.
• Pre-processing Workshop: Includes cleaning, crushing, steaming, and roasting processes. Equipped with oil presses and refining machinery.

Small Oil Press Production Line Configuration List

The small-scale oil extraction production line consists of a screening machine, oil press, roasting machine, oil filter, refining equipment, and packaging machine. Equipment is configured based on raw materials and production capacity.

• Pretreatment：The first in this step is cleaning. You will remove various impurities such as sand, leaves, stones, liquids and metals from the edible material using different machines such as a vibrating sieve, destoner, cyclone separator and metal remover. Proceed to soften the raw material in a crusher before hulling then flaking or rupturing it in more machines.
• Expelling：You will then expel the oil from the kernel by using a press. This can either be a cold press where you only use pressure or a hot press where you include heat and chemicals.
• Extraction：It is here that you extract the oil from the raw material using extraction machines. They remove the oil using mechanical pressure and further by chemical solvents.
• Refining：In this step you will refine the material further by using refining machines to remove unwanted pigments, flavours and chemicals. This makes the oil fit for human consumption.
• Filling：You are now ready to package your oil into bottles using filling machines which fill, label and seal your oil products.

Oil Extraction Equipment Production Process Flow

The screw oil press is a fully automatic hydraulic edible oil processing machine that uses a rotating screw shaft to continuously and efficiently extract oil from raw materials. Its core advantages lie in its compact structure, user-friendly operation, and high oil yield. Widely adopted by individual entrepreneurs, small-scale oil mills, and agricultural cooperatives, it supports the pressing of over 30 types of oilseeds, including peanuts, soybeans, rapeseed, and sunflower seeds.

• Employing a multi-stage progressive pressure increase principle, the chamber pressure rapidly escalates to achieve single-pass fission separation of oilseeds.
• Equipped with an infrared temperature control system, it automatically regulates pressing temperature (120-160°C) and moisture content to soften and activate oil molecules, enhancing oil yield while ensuring product quality.
• Supports both cold and hot pressing modes to accommodate varying oilseed characteristics.
• The vacuum filtration system rapidly separates oil residue, ensuring pure oil quality that meets sanitary inspection standards.

Hydraulic oil presses are designed based on Pascal’s principle (a principle of hydraulics). Within a sealed container, any change in pressure at a single point in a balanced fluid transmits to all directions with equal magnitude. By generating substantial pressure through the hydraulic system and applying it to the oilseeds, the oil within the seeds is squeezed out.

• High Oil Yield: Utilizing a multi-stage progressive pressure increase mechanism, the pressing chamber rapidly builds pressure to achieve complete oil separation in a single pass. Simultaneously, an infrared temperature control system automatically regulates pressing temperature and moisture content, directly softening the oilseeds to activate oil molecules. This ensures stable pressing and thorough extraction in one pass, significantly boosting oil yield. Compared to older equipment, normal oil yield can be 2 to 3 percentage points higher.
• Pure Oil Quality: Equipped with vacuum filtration and an automatic temperature control system, it removes residues from the oil, ensuring pure oil quality that meets health and quarantine standards.

Refining machines are critical equipment used to enhance material purity and remove impurities. They are widely applied in rubber recycling, oil processing, precious metal purification, textile and chemical fiber industries, as well as chocolate production. Their core function is to optimize material quality through physical or chemical methods, meeting diverse industry demands for high efficiency, energy savings, environmental protection, and intelligent operation.

What raw materials can an oil press process?

• Soybeans: Oil yield approximately 12%-18%. After pressing, the soybean meal can be used as feed or a protein source.
• Rapeseed (Canola): Oil yield 30%-45%, serving as the primary source of rapeseed oil.
• Peanuts: Oil yield 40%-50%. Peanut oil possesses a rich aroma and high market value.
• Cotton seeds: Oil yield 10%-20%. Requires detoxification treatment before pressing. Cotton seed oil is suitable for industrial or edible purposes.
• Sunflower seeds: Oil yield 25%-40%. Sunflower oil is rich in unsaturated fatty acids.
• Sesame: Oil yield 45%-55%. Sesame oil (sesame seed oil) has a distinctive flavor and is suitable for cold pressing.
• Flaxseed: Oil yield 30%-40%. Flaxseed oil is rich in alpha-linolenic acid, making it a healthy cooking oil.
• Perilla seed: Oil yield 35%-45%. Perilla seed oil possesses medicinal value.
• Safflower seed: Oil yield 20%-30%. Safflower seed oil is rich in vitamin E.
• Camellia seeds: Oil yield 20%-30%. Camellia oil is a premium edible oil with excellent storage stability.
• Walnut kernels: Oil yield 60%-70%. Walnut oil is nutrient-rich and suitable for infants and young children.
• Coconut meat: Oil yield 60%-70%. Coconut oil withstands high temperatures, making it ideal for cooking or industrial applications.
• Olive fruit: Oil yield 15%-25%. Olive oil is a core fat in the Mediterranean diet.
• Palm fruit: Oil yield 20%-30%. Palm oil is a high-yield vegetable oil.

Oil presses, with their high efficiency and versatility, can process a wide range of oilseeds and oil-bearing crops, serving applications across agriculture, food processing, and industrial sectors.
