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.

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.

A Comprehensive Guide to Cooking Oil Production Methods

 Edible oil serves as a fundamental ingredient in culinary practices worldwide. Incorporating appropriate amounts of cooking oil not only enhances the nutritional value of meals but also significantly improves the flavor and texture of various dishes. This article explores the primary industrial methods for producing cooking oils, focusing on two predominant techniques: mechanical pressing and solvent extraction.

Mechanical Pressing: Traditional Efficiency
The pressing method represents the optimal choice for oil-bearing crops with high lipid content, including peanuts, sunflower seeds, and soybeans. This conventional approach follows a systematic production sequence comprising:
1. Raw material cleaning and preparation
2. Controlled heating/cooking
3. Mechanical oil extraction
4. Oil clarification/filtration

Cooking oil pressing machine

Modern pressing operations achieve remarkable efficiency, with residual oil content in the processed cake typically reduced to below 8%. The resulting oil generally requires minimal additional processing before being suitable for direct consumption or commercial distribution.

For entrepreneurs considering small to medium-scale operations:
1. Compact integrated press-filter units represent ideal solutions for workshop-scale production
2. Larger facilities processing over 10 tons per day benefit from complete production lines incorporating all essential processing stages

Solvent Extraction: Maximum Yield Solution
The solvent extraction method demonstrates particular effectiveness for materials containing approximately 20% oil content, such as rice bran and specific soybean varieties. For high-oil commodities, manufacturers often implement a preliminary pressing stage to reduce oil content to approximately 15% before proceeding with solvent extraction.

This sophisticated process involves:
1. Comprehensive raw material pretreatment (cleaning, cooking, flaking, expanding)
2. Hydrocarbon-based oil dissolution and recovery
3. Thorough desolventizing of both oil and meal

The remarkable efficiency of solvent extraction reduces residual oil in the final meal to under 1%, creating valuable animal feed byproducts. However, crude oil obtained through this method must undergo complete refining before achieving edible quality. This approach becomes economically viable for operations handling 30 tons or more of materials daily.

Conclusion: Selecting the Appropriate Method
Both mechanical pressing and solvent extraction offer distinct advantages for different production scenarios and scales. The optimal choice depends on multiple factors including raw material characteristics, production volume requirements, and investment capacity.

As a professional provider of oil processing solutions, Henan Company offers comprehensive technologies and equipment for both production methodologies. Our engineering team stands ready to assist you in developing the most efficient and profitable oil production system tailored to your specific requirements.
