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.

Why Your Groundnut Oil Turns Cloudy or Smells Off—And How Refining Solves It

Are you a groundnut oil producer struggling with cloudy oil, unpleasant odors, or short shelf life? You're not alone. A common challenge many face is that freshly pressed crude oil becomes turbid or develops off-flavors within months. The root cause often lies not in the pressing itself, but in the missing step that guarantees quality: refining.

At Henan Glory, we understand that quality is what builds trust and grows your business. Let's break down how a dedicated groundnut oil refining machine transforms crude oil into a clear, stable, and market-ready product by removing specific impurities at each stage.

1. Degumming: Eliminating Turbidity

The cloudiness and sediment you see in stored crude oil are primarily caused by phospholipids. Customers reject cloudy oil, hurting your sales.

Our Solution: In our degumming process, crude oil is heated and stirred while a phosphoric acid solution is introduced. This causes phospholipids and other colloids to coagulate. After settling, these impurities are removed, resulting in a visibly clearer oil that stays stable on the shelf.

2. Deacidification: Ensuring Freshness & Longevity

Free Fatty Acids (FFA) are responsible for off-flavors and rapid spoilage, directly cutting into your profits.

Our Solution: Through a controlled reaction with an alkaline solution in our deacidification system, FFAs are neutralized and removed as soapstock. This crucial step significantly extends your oil's shelf life and ensures a clean, neutral taste.

3. Decolorization: Creating the Perfect Golden Hue

Crude groundnut oil's dark color, from natural pigments and oxidation, is less appealing to consumers who expect the attractive golden-yellow oil seen in stores.

Our Solution: Our decolorization process uses activated clay under precise heating and stirring to adsorb these pigments. The result is a consistently beautiful, market-favored color that enhances your product's visual appeal.

4. Deodorization: Delivering a Neutral, Pure Taste

Unwanted raw or burnt notes (often from pressing variations) can deter consumers. Modern buyers prefer a clean, neutral edible oil.

Our Solution: Our deodorization pot operates in a high-temperature vacuum. This steam-strips all volatile odor compounds without oxidizing the oil, guaranteeing a bland, pure flavor profile that meets consumer expectations.

Scalable Solutions for Your Growth

Our batch refining systems are ideal for plants processing under 20 tons daily. As you expand, the system can be upgraded to a semi-continuous setup (e.g., with a continuous deodorization tower), boosting capacity to 30 tons/day with better efficiency.

For large-scale operations exceeding 30 tons daily, we provide fully continuous, automated refining lines designed for maximum throughput and consistent, premium quality.

Invest in the quality that builds your brand. If you're facing issues with oil clarity, shelf life, color, or odor—or if you're planning a new or upgraded your peanut oil refining line—let's connect.

How many types of refining methods are there in the edible oil refining process? For those planning an edible oil refinery, this is a key question. Edible oil refining methods are mainly classified by operation mode and deacidification technology.
By operation mode, there are three types: batch refining system, semi-continuous refining system, and full-continuous refining system. By deacidification technology, there are two: chemical refining and physical refining. Choosing the right one is vital for your refinery's success.

First, let's clarify the 4 core stages of edible oil refining: degumming, deacidification, decolorization, and deodorization. These stages remove gums, free fatty acids (FFA), pigments, and off-flavors from crude oil, improving storage stability, flavor, and color to meet edible standards. All three operation modes cover these four stages—their similarities lie in this core function, while differences determine your choice.



Key Differences Between the Three Refining Systems

1. Equipment Configuration: Batch systems use four independent tanks (degumming, deacidification, decolorization, deodorization). Semi-continuous systems replace the deodorization tank with a deodorization column. Full-continuous systems use both decolorization and deodorization columns instead of tanks, with optimized supporting equipment.

2. Automation Level: Batch systems process oil batch by batch, requiring frequent manual operation. Semi-continuous systems achieve continuity only in deodorization. Full-continuous systems run automatically throughout the entire process, ensuring stable quality and low labor input.

How to Choose the Right Refining Method?

Your choice depends on capacity, crude oil type/finished oil requirements, and budget.

1. Capacity: Batch systems suit small scale (1-10 T/D) due to low investment. Semi-continuous systems fit medium scale (20-50 T/D), balancing efficiency and cost. Full-continuous systems are for large scale (50+ T/D), with high throughput and low long-term costs.

2. Crude Oil & Quality Requirements: High FFA crude oil (palm oil, rice bran oil, coconut oil) needs physical refining—semi-continuous or full-continuous systems (using columns with direct steam) are ideal, with lower oil loss. Batch systems use chemical refining (NaOH neutralization), suitable for low FFA crude oil but with higher loss.

3. Budget: Batch systems have the lowest initial cost. Full-continuous systems have the highest initial investment but the lowest operating and labor costs long-term.

Boost Your Palm Kernel Oil Yield: The Power of Modern Palm Nut Crushing & Shell Separation

For those in the palm oil industry, efficiency is everything. The traditional, manual methods of processing palm nuts are not only slow and labor-intensive but also limit your potential output and profit.

The key to unlocking higher productivity lies in automating the core steps: cracking and separating. Today, we’re highlighting how an advanced palm kernel nut crusher and palm nut shell separator work together to revolutionize your production line.

Why Upgrade to an Automated System?

Maximized Kernel Recovery: Our specialized palm kernel nut crusher is designed to crack nuts by size. This precise cracking action significantly reuses the rate of broken kernels, ensuring you get more high-quality, whole kernels from your raw material.

Perfectly Clean Separation: After cracking, the mixture of kernels and shells needs to be cleaned. This is where the palm nut shell separator comes in. Using advanced air separation technology, it cleanly blows away lighter shells, allowing the denser, valuable kernels to be collected separately. The result is pure, dry kernels ready for high-quality oil extraction.

Lower Costs, Higher Profits: By automating this process, you drastically reduce reliance on manual labor and minimize human error. This translates directly to lower operational costs and a faster return on your investment.

See the System in Action!

Words can only say so much. In the video below, you can see the entire automated process—from the initial cracking in the palm kernel nut crusher to the final, clean separation in the palm nut shell separator.

Palm Kernel and Shell Separation: 3 Common Methods

Separating palm kernels from their shells is a key step in palm oil processing. Based on practical experience, there are three main methods for this separation—including traditional practices and advanced technical solutions. Henan Glory Company will elaborate on each method for you.

1. Traditional Water Separation Method in Nigeria
In Nigeria, local people commonly use the water separation method to separate palm kernels and shells. This is a manual process that requires significant labor input, leading to high labor costs. Additionally, the palm kernels retain substantial moisture after separation, which can impact the quality of the resulting palm kernel oil.

2. Crushing + Manual Separation Method
Some users first use a palm kernel crushing machine to husk palm nuts, then rely on workers to separate kernels and shells using sieves. This method also has low efficiency. Some customers have reported using vibrating screens for separation, but the results are unsatisfactory due to the similar weight of palm kernels and shells—gravity alone is insufficient for effective separation, resulting in a low separation rate.

3. DOING Palm Kernel Cracker and Shell Separator System
To address the challenges of difficult separation and low production efficiency, engineers at Henan Glory Company conducted extensive research and testing to develop the palm kernel cracker and shell separator system.

This system combines gravity and air separation technologies, leveraging differences in weight and force-bearing area between kernels and shells. During operation, palm kernels fall downward under gravity, while shells are lifted to the top by airflow and discharged through a dedicated outlet. The entire process is fully automatic, resolving issues related to separation efficiency and automation.

The DOING Brand palm kernel cracker and shell separator system has been exported to numerous countries, including Nigeria, Ghana, Ivory Coast, and Uganda. If you aim to improve separation efficiency and reduce labor costs, contact us today—we will provide operation videos and offer factory-direct pricing.

Skip Costly Repairs & Keep Production Flowing: Essential Upkeep Tips for Your Soybean Oil Press Machine

Your soybean oil press machine is the backbone of your oil production—keeping it running smoothly isn't just a task, it's a way to avoid costly downtime and keep oil quality consistent. With simple, regular upkeep, you can extend its lifespan and cut down on repairs. Here's Henan Glory's go-to maintenance playbook:

1. Non-Negotiable Daily Cleanup

After every shift, tear down the press chamber to clear leftover soybean cake. Hardened cake buildup clogs the chamber, strains the motor, and risks bacterial contamination in future batches. Wipe the machine's exterior too—oil and dust buildup turns into a tough, grimy layer that's a hassle to remove later. If the press sits idle for over an hour, pull out the screw shaft to clear hidden cake scraps (this prevents jams when restarting).

2. Lubrication: Keep Parts Moving Smoothly

Key moving components depend on proper lubrication to avoid wear:

Screw shaft: Lubricate it at the start of every shift to prevent dry grinding damage.
Gearbox: Check the oil level every 50 operating hours; replace the oil (and inspect its quality) once a year.
Bearings & bushings: Lubricate them regularly, and clear clogged oil holes right away. Neglecting this leads to overheated bearings or seized parts—costly to fix and disruptive to production.

3. Read the Signs: Spot Issues Early

Your press machine gives clear warnings when something's off—learn to "listen and look":

Unusual noise: Shut down immediately (this could mean a metal fragment/stone in the chamber, or a loose fastener).
Cloudy oil: Likely from overly dry soybeans or low machine temperature (aim for 60-70℃—the exterior should feel warm to the touch).
Low pressing capacity/excess slag leakage: Check for worn screw shafts, misaligned press bars, or too much chamber pressure.

Address these small issues fast (e.g., replace worn parts) to keep oil quality high and avoid bigger breakdowns.

4. Proper Shutdown: Don't Just Flip the Switch

Shutting down correctly prevents buildup and damage:

1-2 minutes before powering off, close the feed plate to stop adding soybeans.
Reverse the screw shaft 2-3 times to widen the cake outlet gap—let all leftover slag/cake fully discharge.

Only then turn off the power switch.

5. Long-Term Storage: Prevent Rust & Damage

If the press will be idle for a while:

Disassemble key parts (screw shaft, press bars, cake outlet ring) and clean them thoroughly.
Coat parts with a thin layer of oil to prevent rust.
Store everything in a clean, dry area—so your press is clog-free and ready to run when production resumes.
