Efficient Oilseed Flaking Process for Enhanced Oil Extraction
Date:Jul 22nd, 2024
Oilseed flaking, also known as pressing, is a critical step in oil extraction, where oilseeds are transformed from granular form into flakes. This process, involving mechanical action, enhances oil yield and quality.
Purpose of Flaking:
Cell Structure Disruption: The hard cell walls of oilseeds encase oils and other substances. To extract the oil, these walls must be broken down. The flaking process uses rollers to compress the seeds, breaking the cell walls and allowing easier oil extraction.
Shortened Oil Pathway: Flaking reduces the distance the oil must travel to be extracted, facilitating both pressing and extraction processes.
Improved Cooking and Steaming: By increasing surface area and reducing thickness, flaking allows oilseeds to absorb moisture and heat more efficiently during steaming, accelerating protein denaturation and cellular changes.
Flaking Process Requirements:
To ensure optimal results, the flaking process must meet specific quality standards:
Uniform Flake Thickness: Consistent flake thickness is crucial for even cooking and achieving high-quality cooked flakes.
Minimal Powder Content: Excessive powder can cause clumping during cooking and hinder solvent penetration in extraction, leading to cloudy oil and extraction difficulties. Monitoring and adjusting the flaking process helps maintain ideal powder levels.
Types of Flaking Machines:
Flaking machines utilize rollers to compress oilseeds into flakes and can be categorized by roller arrangement (parallel, inclined, vertical) and tension mechanisms (spring or hydraulic). The most common type is the parallel roller flaker, which includes:
Hydraulic Roller Flaker: Suitable for large and medium-sized oil factories due to its high pressure and fast processing speed.
Spring Roller Flaker: Typically used in small and medium-sized oil factories.
Both machines share similar components, including feeders, rollers, distance adjustment devices, scrapers, and drive mechanisms.
Operation of Flaking Machines:
Roller Integrity: Rollers must be perfectly round without radial or axial movement during operation.
Blade Contact: Scraper blades should maintain good contact with the roller surface.
Pre-screening: Only pre-screened and demagnetized oilseeds should enter the flaking machine.
Even Distribution: Oilseeds must be evenly distributed across the roller surface with a consistent flow rate.
Quality Control: Regularly check flake quality for uniform thickness, sampling from multiple roller segments for comparison.
Handling Blockages: Immediately stop feeding and adjust or clear the machine in case of blockages.
Avoid Empty Running: Rollers should not run empty without releasing pressure, as this can damage the roller surface.
Roller Clearance: Ensure proper clearance between roller ends and machine frame to prevent leakage.
Emergency Shutdown: In case of sudden stops, immediately close the feed gate and release the oilseeds.
Safety Precautions: Avoid contact with rollers during operation and ensure protective guards are in place.
Lubrication and Maintenance: Regularly check bearing lubrication and replace or refurbish as needed.
By following these guidelines, the flaking process can significantly enhance oil extraction efficiency and quality.
