Here is how it's done:

(scroll down to bottom of page to see some simple set-ups) 

1) Get your seed to the press:
 If you have the headroom then an overhead hopper can keep the press filled using gravity, if not then a low cost auger with level sensor be used to keep the press topped up from a larger seed bin or silo.
2) Press the seed:
The oil press takes in seed and expels oil from the barrel of the press and cake (or meal) from the end. The cake can fall into a bin or trailer (if the press is high enough) or conveyed - usually by a belt conveyor. The oil can also employ gravity (which is very cheap and reliable!) to drain into the collection tank below the press or can be pumped to a remote tank. 
3) Allow the oil to settle (small batch processing):
This takes about 10 days depending on ambient temperature and seed condition. More settling tanks means more total system capacity. After settling the oil must be filtered through a polishing filter to give crystal clear oil. A better system is to use continuous filtering (see next option)
3) Filter the oil straight off the press (larger continuous processing):
To produce oil continuously we need to remove the solids from the oil as soon as it comes from the press. This can be done using a special type of filter called a frame filter that has a high solids holding capacity. With this method the settling tanks are not required. See the 'Oil Filters' page.
4) Storage in a holding tank.
This tank holds your clean oil ready for packaging or into bulk tanks.

If making food oils then:

5) Fill your bottles
A volumetric or vacuum filler can be used. 
6) Fit the cap:
If you want to use tamper evident aluminium caps (such as found on many wine bottles) then an ROPP capping machine is used to push on the cap and form the threads. Plastic caps can be applied by hand or using a simple pneumatic tightner.
7) Apply the label:
The cheapest way is to stick them on by hand. Next level up is a simple manual machine (gets them on nice and straight and at the same level - about 300 per hour). For higher volumes a semi-automatic machine that can apply front and back labels and a best before date all in one operation (about 600+ per hour).

Various automatic machines are available to fill, cap and label using a conveyor belt system. Details available on request.
