Mechanical Press Cold Press or Expeller Press
Cold Press Extracts oil without heat preserving more nutrients and flavor Its suitable for highvalue oils like olive or coconut oil
Expeller Press Uses mechanical force to squeeze out the oil which may involve some heat Its suitable for a wide range of seeds and nuts
Solvent Extraction
Uses Chemicals This method involves using solvents like hexane to dissolve the oil which is then separated from the solvent Its efficient for extracting oil from oilseeds but requires additional steps to remove the solvent
Hydraulic Press
Traditional Method Uses hydraulic pressure to extract oil Its less common in modern industrial settings but can be used for smallscale production
2 Features to Consider
Capacity Depending on your needs choose a machine with the appropriate processing capacity from small home models to large industrial machines
Material Look for machines made of highquality durable materials like stainless steel for longevity and hygiene
Efficiency Consider the oil yield efficiency and how well the machine separates the oil from the residue
Ease of Use and Maintenance Machines with userfriendly interfaces and easy cleaning procedures are preferable
Energy Consumption Check the energy requirements to ensure it fits within your operational costs
3 Applications
Home Use Small affordable machines are available for home use ideal for making oil from seeds like flax or sesame
Commercial Use Larger more advanced machines are used in the food industry for mass production of cooking oil
4 Steps in the Extraction Process
Cleaning Seeds or nuts are cleaned to remove any impurities
Grinding The cleaned seeds are ground into a paste or meal
Pressing The paste is then pressed to extract the oil In cold pressing no heat is used whereas in expeller pressing heat might be generated
Filtering The extracted oil is filtered to remove any remaining solid particles
Refining if needed The oil might be refined to remove impurities improve flavor or enhance shelf life
