How to Plan a Sunflower Oil Processing Plant: Capacity, Extraction and Equipment

Planning a sunflower oil processing plant is not simply a matter of choosing an oil press.

The plant configuration should be determined by several factors, including the available sunflower seed supply, target processing capacity, required oil recovery, final oil quality and available infrastructure.

For this reason, it is usually better to define the process first and select individual machines afterward.

1. Start With the Required Processing Capacity

Capacity is one of the first decisions because it affects equipment size, plant layout, utilities, automation and investment.

As a general reference, sunflower oil processing projects can be considered in three ranges:

• 1–20 TPD: Small-scale projects, commonly based on mechanical pressing
• 20–50 TPD: Medium-scale projects, where mechanical pressing or solvent extraction may be considered
• Above 50 TPD: Larger commercial and industrial projects, where mechanical pressing and solvent extraction may both be evaluated

These ranges are not fixed rules. The final configuration should also consider the available sunflower seed supply, expected annual operating volume, investment level and planned automation.

2. Choose the Right Oil Extraction Process

The two main extraction routes are mechanical pressing and solvent extraction.

Mechanical Pressing

Mechanical pressing uses a screw oil press to extract oil from prepared sunflower seeds without chemical solvents.

Its main advantages are:

• Simpler process flow
• Lower initial investment
• Easier operation and maintenance
• No solvent recovery section

For smaller sunflower oil projects, mechanical pressing can therefore be a practical choice.

Solvent Extraction

Solvent extraction is used to recover additional oil from the press cake after mechanical pressing.

The major advantage is higher overall oil recovery. Under appropriate operating conditions, the residual oil content of the extracted meal can be reduced to below 1%.

However, solvent extraction also requires additional processing equipment, utilities, safety systems and operating controls.

Therefore, the better question is not simply which extraction method is better. The choice should be based on the project's capacity, oil recovery target, investment level and operating conditions.

3. Build the Equipment List Around the Process

A sunflower oil processing plant normally consists of several connected processing sections.

A typical flow is:

Sunflower Seeds → Cleaning → Dehulling & Flaking → Conditioning → Oil Extraction → Crude Oil Filtration & Storage → Refining → Dewaxing → Filling & Packaging

Depending on the selected process, equipment may include:

• Vibrating screen
• Magnetic separator
• Destoner
• Dehuller / cracker
• Shell separator
• Flaker
• Cooker or conditioner
• Screw oil press
• Solvent extraction system
• D.T.D.C. system
• Oil filtration and storage equipment
• Refining equipment
• Dewaxing equipment

The equipment list should therefore be developed from the complete process flow instead of selecting machines independently.

4. Refining Is a Separate Stage From Oil Extraction

Mechanical pressing or solvent extraction produces crude sunflower oil.

Crude oil still contains substances such as phospholipids, free fatty acids, pigments, waxes and odor compounds.

A typical refining sequence is:

Degumming → Deacidification → Bleaching → Deodorization

Each stage addresses a different quality issue, helping improve the color, stability, odor and overall quality of the oil.

The required refining configuration also depends on production capacity, finished-oil requirements and the desired level of automation.

5. Why Dewaxing Matters for Sunflower Oil

Sunflower oil contains natural waxes that can crystallize at lower temperatures.

If these waxes remain in the finished oil, the oil may become cloudy during cool storage.

Dewaxing uses controlled cooling, crystallization and filtration to separate these waxes and improve the clarity of sunflower oil.

For projects producing clear packaged edible sunflower oil, dewaxing should therefore be considered when defining the overall refining configuration.

6. Project Experience Matters When Selecting a Plant Configuration

The same equipment configuration is not necessarily suitable for every sunflower oil project.

Henan Glory has supplied sunflower oil processing and related equipment for projects in different countries and at different production scales, including:

• Tanzania — 50 TPD: Pressing + solvent extraction
• Peru — 20 TPD: Sunflower oil refining
• Uzbekistan — 5 TPD: Refining + filling

These projects cover different stages of sunflower oil production, showing why plant configuration should be matched to the actual project requirements.

Final Consideration

Before investing in a sunflower oil processing plant, it is useful to define five things first:

1. Available sunflower seed supply
2. Target daily processing capacity
3. Required oil recovery
4. Finished oil quality
5. Available infrastructure and investment conditions

Once these are clear, the extraction route, equipment configuration, refining system and dewaxing requirements can be evaluated as one integrated process.

Henan Glory provides sunflower oil processing configurations from 1 to 2,000 TPD, covering mechanical pressing, solvent extraction, refining and dewaxing.

Crude Oil Refining Equipment: Key Machines & Their Roles

Are you looking to improve oil quality and optimize production efficiency with right oil refining equipment for your edible oil processing plant? Drawing on years of industry experience, Henan Glory outlines the key machines for the crude oil refining equipment and their roles—to help you gain a clearer understanding of the equipment's value at each stage.

1. Degumming: Key Machines Used to Remove Phospholipids and Impurities

Degumming is the first step in oil refining, primarily aimed at removing hydrated and non-hydrated phospholipids, as well as particulate impurities, from crude oil.

Key Machines and Their Roles: 

Degumming Tank: The degumming tank is the core reaction vessel in the degumming process. Crude oil, preheated by a heat exchanger, enters the tank along with degumming agents such as phosphoric acid. The tank is typically equipped with a stirring device to ensure uniform mixing of the oil and reagents. Its stainless steel structure and sealed design effectively prevent contamination and ensure stable reaction conditions.

Heat Exchanger and Heater: Precisely controlling the oil temperature entering the degumming tank is crucial for ensuring the smooth progress of the hydration reaction.

Sealed Filter: As an auxiliary process, it can remove trace impurities from the oil.

2. Deacidification: Key Machines Used to Remove Free Fatty Acids

Deacidification aims to remove free fatty acids from oils to improve flavor stability and extend shelf life. Chemical neutralization is the most commonly used method.

Key Machines and Their Roles: 

Deacidification Tank: The key machine for batch crude oil refining. This multifunctional tank, equipped with stirring and heating, completes the entire deacidification process in one vessel. The process involves adding an alkali, heating and stirring to form soapstock, and then allowing it to settle for separation from the oil.

Disc Centrifuge: Essential for continuous crude oil refining equipment. Its high-speed rotation generates a powerful centrifugal force that enables highly efficient separation of soapstock, the by-product of deacidification.

Metering Pump: Accurately measures and delivers phosphoric acid and alkali solution.

Vacuum Dryer: Removes excess water from the washed oil.

3. Decolorization: Key Machines Used to Adsorb Pigments and Trace Impurities

Decolorization is the process of removing pigments (carotenoids, chlorophyll) and residual soap particles from oils using adsorbents (such as activated clay). The selection of equipment must be differentiated based on continuous and batch modes.

Key Machines and Their Roles:

Decolorization Tank/Tower: Continuous crude oil refining equipment uses a decolorization tower. Activated clay is added via an automatic quantitative feeding system and mixed with the oil preheated to 90°C within the tower. This equipment operates under vacuum conditions to prevent oxidation of the oil during heating. The resulting mixture is then filtered to separate the waste activated clay from the oil.

Activated Clay Quantitative Feeding System: Primarily used with continuous equipment to achieve precise addition of the adsorbent.

Heater: Controls the adsorption temperature required for decolorization.

Leaf Filter: Separates the decolorized oil from the waste activated clay.

4. Deodorization: Key Machines Used to Remove Odor-Causing Substances

Deodorization removes volatile substances that cause odors under high temperature and high vacuum conditions through steam distillation, enhancing the oil’s flavor.

Key Machines and Their Roles: 

Deodorization Tank/Tower: The deodorization tower is the key machine for continuous production, typically a complex vertical tower. It is made of stainless steel to withstand the high temperature (260°C) and the corrosion during deodorization. The decolorized oil undergoes continuous heat exchange and steam stripping within the tower, effectively removing volatile substances.

Vacuum System: Creates and maintains a high vacuum environment throughout the deodorization process, such as a steam jet pump.

Fatty Acid Collector: Recovers volatile fatty acids generated during deodorization as a byproduct.

Heat Exchange System: Significantly reduces steam consumption and achieves energy savings through efficient waste heat recovery.

Supporting and Control Systems

Semi-continuous and fully continuous refining equipment relies on a PLC-based automatic control system. This system automatically adjusts key parameters such as the temperature, pressure, flow rate, and stirring speed, minimizing human error, ensuring stable system operation, and effectively lowering labor costs. In contrast, batch refining equipment is mostly operated manually, where individual instruments monitor parameters such as the temperature and pressure of each piece of equipment. Manual adjustment is required, making it highly dependent on the operator's experience.

Finding the Right Oil Press: A Guide to Peanut Oil Processing Machines for Small-Scale Producers

For small-scale peanut oil producers, choosing the right press isn't just about buying equipment—it's about defining your business. The right machine balances efficiency, oil quality, and cost, shaping everything from your daily output to your market appeal. Whether you're supplying local communities or targeting premium buyers, understanding your options is the first step to success.

Here's a breakdown of the three most common types of oil presses found in small processing plants, each with its own strengths.

1. The Workhorse: Screw Oil Presses

If you need reliable, continuous operation for moderate-scale production, the screw press (or expeller press) is likely your best match. It works by forcing peanut kernels through a rotating screw, mechanically squeezing out the oil.

Best for: Producers prioritizing steady output and automation.
Typical Daily Capacity: 5–20 tons of peanuts.
Oil Yield: Around 35–45%, depending on kernel quality.

The Bottom Line: It's efficient, requires less manual labor, and is a cost-effective choice for supplying broader markets. Keep in mind that the crude oil will need filtering, as it may contain some solids from the pressing process.

2. The Artisan Choice: Hydraulic Oil Presses

When oil purity, flavor, and nutrient retention are your top priorities, the hydraulic press shines. It uses controlled hydraulic pressure to squeeze oil from peanut meal in batches, a gentler process that generates less heat.

Best for: Craft or "cold-pressed" oil producers targeting premium, health-conscious, or local artisan markets.
Typical Daily Capacity: 1–5 tons (batch processing).
Oil Yield: A slightly higher 40–48%, with exceptional purity.

The Bottom Line: This method preserves the peanut's natural aroma and nutritional value beautifully, often requiring less filtration. The trade-off is a slower, batch-based process that may limit large-scale volume.

3. The All-in-One Solution: Integrated Pretreatment & Pressing Systems

Why stop at just pressing? Integrated systems combine cleaning, shelling, roasting, and pressing into one streamlined workflow. A common setup pairs a roasting machine with a screw press, preheating the peanuts to optimize oil flow and flavor.

Best for: Processors looking to maximize efficiency, consistency, and control over the entire production chain.
Key Advantage: Preheating (to 120–130°C) can boost oil yield by 3-5% and creates that beloved, rich roasted peanut aroma. It minimizes handling and ensures a uniform product.

The Bottom Line: While the upfront investment is higher, the gains in productivity, oil quality, and operational smoothness can quickly justify the cost for a growing business.

For many, the screw press offers the best balance to start. Those in niche markets may lean toward hydraulic presses, while integrated systems are the goal for scaling up efficiently.

A Final Note on Sourcing: Many reliable manufacturers, such as Henan Glory Company, offer these standard presses and even have overseas warehouse networks to support international customers. It's worth researching suppliers who can provide not just the machine, but also the technical support and parts you might need.

By carefully matching your equipment to your vision, you can build a small peanut oil processing operation that is both sustainable and competitive.

Where can I buy small scale palm oil refinery machine(1-20tpd)?

For small and medium-sized producers looking to turn crude palm oil into clear, stable, and market-ready edible oil, Henan Glory Company's batch type palm oil refinery machine offers the perfect balance of efficiency and flexibility. With capacities ranging from 1 to 20tpd, this refinery is designed to deliver high-quality refined palm oil while keeping operational costs manageable.

Why Choose a Batch Type Palm Oil Refinery Machine?

Unlike large continuous systems, batch type refining allows you to process oil in controlled, separate lots. This is especially useful if you work with multiple oil types—such as palm, soybean, sunflower, or peanut oil—and need to switch between them without downtime or cross-contamination. Whether you're starting with 1 TPD or scaling up to 20 TPD, batch systems give you the adaptability to meet changing market demands.

Four Key Steps to Purity and Quality

The batch refining process follows four essential stages, each targeting specific impurities in crude palm oil:

1) Degumming – Removes phospholipids and gums through hydration, preventing forming and discoloration during heating.

2) Deacidification – Uses alkali neutralization to eliminate free fatty acids (FFA), improving oil stability and shelf life.

3) Bleaching – Adsorbs unwanted pigments like chlorophyll and carotenoids using activated clay, resulting in a clearer, brighter oil.

4) Deodorization – Conducted under high-temperature vacuum distillation, this step removes odor-causing compounds. The deodorization tank, made from corrosion-resistant 304 stainless steel, ensures the oil does not re-oxidize, preserving its natural quality.

Together, these stages ensure that the final product meets national edible oil standards while retaining the oil's natural nutrients.

Tailored Heating Options for Different Scales

To suit various production needs, batch refinery machines come with two heating choices:
1) Electric Heating – Ideal for small workshops (0.5, 1, or 2 TPD), featuring all-stainless-steel construction and lower upfront investment.

2) Thermal Oil Heating – Recommended for larger outputs (1–20 TPD), this method uses a thermal oil furnace and coil system for energy-efficient, consistent heating of larger batches.

Eco-Friendly and Cost-Effective Design

Modern batch refineries are built with closed-system technology, minimizing exhaust emissions and reducing residue pollution. This not only helps you comply with environmental regulations but also lowers waste management costs.
