Amafilter® filtration solutions
in edible oil applications

Filtration is an essential part of the edible oil purification process. Without it, the final product that reaches the supermarket shelves, like vegetable oil, for example, wouldn’t be fit for use or consumption.

In short, it’s ideal for the food and biofuel oil industries. And the best way to ensure your oil is filtered efficiently and cleanly is with the amafilter® Cricketfilter® fully automated system or the Versis® pressure leaf filter system.

Which edible oils are suitable for filtration?

The filtration process ensures undesirable particles are removed from the edible oil while maintaining the quality of the final product. And it’s not just vegetable oil that needs to undergo this process.

The Cricketfilter® and the Versis® systems are used to process a variety of oils, including:

• Avocado oil
• Palm oil

• Peanut oil / groundnut oil
• Rice bran oil

• Grapeseed oil
• Safflower oil

• Sesame oil
• Sunflower oil

• Olive oil
• Mustard oil

The Cricketfilter® edible oil filtration process

The Cricketfilter® is an automated self-cleaning system which can be used after the extraction of the oil from the seeds or after pressing of the oil from the seeds.
Depending the type of oil that is being filtered and its final purpose, the oil may undergo several different processes:

Hot/cold-pressed:
• Full or pre-pressing of seeds by expeller press
• Pre-screening
• Removal of foots out of pre-screened oil

Filtration process:
Pressure leaf filter system direct filtration, 60 mesh
Cricketfilter® system direct filtration
• Safety filter
Bag filter

• Removal of bleaching earth (clay) / silica / activated carbon out of refined and bleached oils and fatty acids
• Removal of colour and other components

Main filtration process:
Pressure leaf filter system 24×110 (standard in the market)
• 60×60 wire mesh for direct filtration and precoat filtration (e.g. cellulose as a filter aid) for winterised edible oil
Cricketfilter® direct filtration

Heel filtration:
Cricketfilter® – wet cake discharge

Safety filtration:
Bag filter

Polishing filtration:
Cartridge filter

• Formation of nickel salts by adding (citric) acid (post-treatment / bleaching or nickel scavenging)
• Removal of residual nickel catalyst/bleaching clay from hydrogenated oil

Heel filtration:
Cricketfilter® – wet cake discharge

Safety filtration:
Bag filter

• Removal of impurities formed during the deodorisation process

Safety filtration:
Bag filter

Polishing filtration:
Cartridge filter

• Removal of solids from miscella
• Production of lecithin from gums
• ATEX environment

Filtration process:
• The Versis® pressure leaf filter system precoat and body feed filtration downstream the evaporators

• The Cricketfilter® system directs filtration upstream the evaporators

• Removal of catalyst after hydrogenation or intensification
• ATEX environment

Main filtration process:
Cricketfilter® – dry cake discharge

Heel filtration:
Cricketfilter® – wet cake discharge

Safety filtration:
Bag filter

• Removal of waxes from winterised oil, mainly from sunflower oil, to enhance cold stability

The benefits of using the Cricketfilter® in edible oil filtration

The benefits of implementing the Cricketfilter® in edible oil filtration include the removal of:

1 Gums and other impurities from the oil result in a high quality oil that is ready for further treatment and its effective use in other processes.

2 Colour and other components result in a clear, light high purity oil.

3 Nickel catalyst after hydrogenation of the oil (which can then be recycled).

The selection of the correct filter type for each process step also depends on several factors, including:

• Space availability
• Type of cake discharge
• Filter unit size in combination with the plant capacity
• Batch or continuous operation
• Investment costs

So, if you’re unsure of any of the above and need some advice, no problem.

Our team of experts at Amafilter® work closely with every customer to identify the very best filtration solution to meet their unique needs and requirements.
