The oil that comes off the oil press must be filtered as it contains small pieces of shell and fine seed pulp called foots.

For smaller scale batch production it is possible to simply allow the oil to settle for several days in a settling tank, this allows most of the solids to fall to the bottom of the tank. The oil above the sediment can then be pumped through a polishing filter to give crystal clear oil.

For larger scale production (for example with one or multiple presses running day and night) the oil can be continuously pumped through a special type of filter that will remove the suspended solids straight off the press, this means the oil can be filtered as soon as it is pressed (no need to leave it for days to for settle). Continuous filtering is achieved using a depth filter, see below:

40cm polishing filter
Culinary grade
With or without pump

This is a polishing filter which is used after oil has been left for several days to settle. Food grade 40cm filter press that will take up to 20 filter cards. This filter will give you crystal clear oil. Complete with valves, pressure guages and a site glass.  
All filters need a pump, food grade mono type pumps are the best, they can pump viscous liquids, with suspended solids. Ours are fitted with a speed controller or pressure control allowing excellent control of the flow rate.
This filter will polish 300 litres of settled oil in a couple of hours. The cards cost about 75p each (with well settled oil that's less than1p/bottle). The capacity depends on how long the oil is left to settle (usually 5 or more days). REMINDER - this type will only filter oil that has been settled for 2 weeks or more. For instant filtering see below.

Depth filters - Filters for immediate continuous filtration, no need to let the oil settle.

This type of filter removes the need for sedimentation and is used where the press or presses will be run for long periods or continuously. No need to allow the oil to settle and no sediment in the bottom of the settling tank to deal with. The filter differs from those above in that it has a high solids holding capacity. Once full the filter is opened and the solids fall or are manually eased from the filter sheets using a simple hand tool like a kitchen spatula. The press is then closed and filtering continues. A food grade filter aid powder such as kieselguhr is used. Sizes range from a 10 plate 200mm filter up to a 50 plate 630mm filter. Models available to filter a few hundred litres per day to several thousand litres per day.
