instructions for Making an oilpress?

Hello,

I discoverd (for myself) that the batch of breadseed from the opium poppy is very good. Then i put it in a pestle and grind, grind and grind....
But i cant get the oil out of it (it contains a lot of oil). It is more like a fatty paste. Is it possible to make a press from a potkrik (i dont know the english name of it but here are pics http://www.google.nl/search?pq=krik&hl=nl&sugexp=gsis,i18n%3Dtrue&cp=3&gs_id=y&xhr=t&q=potkrik&gs_sm=&gs_upl=&bav=on.2,or.r_gc.r_pw.&biw=1280&bih=929&wrapid=tlif131620773657914&um=1&ie=UTF-8&tbm=isch&source=og&sa=N&tab=wi )
Can somebody explain me how to make an oilpress?

Here is one DYI oil press idea http://journeytoforever.org/biofuel_library/oilpress.html  Scroll down for the homemade oil press part.

Here's one for under $200  http://www.piteba.com/

here in balkans people use poppy seeds but not for oil extraction - they make all kinds of sweet food, like strudel. yes it contains lot of oil, so i guess its not problem to make it. heres one way (its about hemp oil extraction, but probably it will work for poppy seeds):

Yup, the Piteba Oil Expeller that's the one I linked to above - nice vid showing how to set it up and use it, thanks.

A search of the forum produces tantalizing hints but no outright statements (that I could find) so I'll ask the question: Is anyone here making their own oil?  Not reusing oil but making from scratch.  In particular, I'm interested in sunflower oil.  Is anyone using the Piteba press? I know about Journey to Forever and the various You Tube videos so I'm looking for first hand experience.

The piteba is a bit expensive for me because i don't know how much i'm going to use it. I think i will make a simple homemade version.

I built the press that is at Journey to Forever for making small batches of biodiesel.  It works pretty well but I would rather have a screw extractor.  I have a friend that bought the screw extractor sold by Northern Tools but it is no longer on their website.  I have been at his farm when he was suing it and it works really well.  I have no clue where to get one though.
I did discover that the press I built is labor intensive and if I build a new one it will have at least twice the capacity.  I only built it to experiment with bio-diesel "chemistry."  I am trying to develop a heating fuel from vegetable oil that will work in a wick style kerosene heater.  Ordinary bioddiesel doesn't wick very well.  My multi-fuel howler works well with biodiesel but it sure is noisy.  The press works  well for sunflower seeds but if I were going to be processing a large quantity of sunflower seeds I would get a screw press.

Mike,  I forgot to mention that I am "tinkering" with converting a #32 meat grinder into a screw press.  So far I have had some set backs but I am encouraged that the glitches can be worked out.  My plan is to either publish the plans, offer the conversion pieces as a kit or both.  A majority of #32 grinder are universal so the part should fit any brand.  Mine happens to be the stainless steel version with a v-belt pulley so it is motorized but I also have an old cast iron hand crank version that I don't use for food because it is so old that it needs tinning.  I had some special plates made at a local machine shop to provide the pressing.  The problem I am trying to solve is oil/cake separation.  I am hoping to wind up with a press that will process a few hundred pounds of seed stock per hour. The plates are 304 stainless so it is food grade.  I am more interested in the fuel aspects than food grade oil although it could be used for either.  I fabricated an accessory that attaches to the grinder where the ground seed presses a second plate after the forcing plate.  If it is successful I will post it here. 

Very interesting Dave, I look forward to seeing what you come up with.

As a side note, I'll bet the hens and hogs would be happy to help you get rid of the press cake.

With the oils removed, the cake would have less calories (energy), but much of the nutrients would remain.

You misunderstood my comment.  I stated that I have been having problems separating the oil and the cake.  I know what the cake is good for I just haven't perfected my homemade screw press.  Too much oil is still in the cake.  I already have been down the road of grinding the oil seed and then using the hydraulic press pictured at journey to forever.  Press cake is spectacular animal feed especially for hogs and chickens. 

I got a Piteba press this summer and I've been using it to press sesame oil. I'm super happy with it, although it doesn't do so well on windy days due to the little oil lamp used to heat the element. I'm just using the oil I press for eating. I'm not sure the Piteba would be serious enough to produce a large quantity of fuel oil. You can hook it up to a bicycle (check youtube), but it still seems kind of small for that to me.

For doing small quantities of oil for eating it is great. I've even thought how cool it would be to have a few stationary bikes hooked up to Piteba presses at a farmer's market. People could come down, ride a bike for 20 minutes and get their cooking oil for the next week or two. It would be fun!

Here are the Pietba extraction numbers for a bunch of different types of seeds -> http://www.piteba.com/eng/index_eng.htm so you can see how much oil/hour to expect from the Piteba.

Friends bought one last year with the hope of pressing their own lamp oil. It has been a failure at that--simply too small to get enough oil to be meaningful for fuel. They do use it to make their own specialty oils and enjoy it for that. They have enough walnuts and other nuts to make the really expensive oils themselves.

I know a good screwpress juicer can make coconut oil, but not sure about nut oils... http://www.youtube.com/watch?v=Am3IKTS2KQw&feature=plcp

But look how slow it is with a heavy duty electric screwpress, doing that by hand would be a workout.

I would be willing to make a hardware store screw press, with instructions and photos, were enough people to be interested.

Hi I'm ed by the way
