    Hi there (kako si ?)
    Here are some links for you have a good look and compare prices as well as output In other words divide output for maximum oil yield in % extracted by dollars or euros and see what the best deal is
    Good luck

    Re: Screw press

    Whydo you want a press? Do you have plenty of seed? It may be more economicalt to have the oil pressed at a specialist facility rather than pressing it yourself. Remember that they are able to extract ~91% of oil in cold pressing and 100% of the oil using solvent extraction.

    If your press cannot get all of the oil out (or even as much as the specialist cold pressers do) you will be losing that oil in the meal. You do not get more for the meal because it has a high oil content, you just lose the oil.

    My advice is to use a specialist oil seed processor to extract the oil from your crop, concentrate on using the oil and solving problems in it's use before taking on another lengthy project. You will have enought ot do concentrating on each individually, rather than both at once.

    I know that this might be a better solution, but I want to sturt my own oil production so I could extract oil for myself and offer services of oil extraction to other people.

    Re: Screw press

    Here is the email address for the dealer of Keller Kek screw presses. He is the Australian distributor for Egon Keller & Co.

    Steven Hobbs: shobbs@wimmera.com.au


    Drop him an email, and he can provide you with product information and prices that are best suited to your project size.

    This is a german made press. The price is higher than an indian or chinese model, but you pay for quality, and it will last longer than the others before the parts need replacing.

    Tell him Dave says hi from Cambodia.

    Goodluck!

    Ok
    Here is a suggestion that you may explore There some plants sitting idle in Greece They where used for olive oil extraction some years back where all of the crop was crushed (pips as well) which needed solvent based refining to get the bitterness out of the oil
    Some installations where not big enough to justify solvent extraction or good at it so the plants where shut the down and left gathering dust in the corner of the factory These are not stand alone screw presses but a hybrid type of a roller crush come screw in one machine
    It is not hard to by pass the roller part and just use the expeller only
    If my memory serves me well they also incorporated a centrifuge which is something that you will be able to use
    They where made by a subsidary of Alfa Laval for small co-op type of operations and they did sell quite a few so they should be quality machines
    It is quite a few years ago that I became aware of them, I am sure if you scratch around there you may be lucky and get yourself one The alternative to that of course is a fat cheque book
    Give this some thought as well You are closer to Greece Germany as well as Holland and Sweden where most of the good gear comes from then we are For us a trip from Melbourne to Brisbane is not a huge deal For you to travell that distance you would go to all these countries and be back home
    Food for thought Bradko
    Cheers

    By the way I do not speak Serbian I know a few words as I have a lot of Serbian friends
    By the way have you got access to an engineering shop with a lathe and some basic tools or are you able to get to a fitter and turner? If so a very good screw press can be made out of the extruder part of an old injection moulding machine or an old extruder
    They are well made even the worse ones Just use the Hydralic drive as well as the screw If you are going to buy one make sure that the barrel is sleeved so as you can remove it, it is as hard as glass you can then resleeve the barrel with another sleeve which is drilled so as to allow the oil to come out Barrels wear out in all presses about 1000 to 1500 hours is the life Of course that is a rule of thumb Some oil seeds are more abrassive than others Putting a restrictor in the front of the barrel so as to control back pressure is not a big deal You can buy these things here for a $1000 and you propobally need to spend another $2-3 K here to get a result But I do know that it will cost you less in Serbia
    If you aim for a hydraulic drive you will also have reversing capabilities as well as full speed control And if the barrel is about 1.5 M long with a screw about 45 mm in diameter you should be getting something like 100 kg of material through it an hour You may even leave the heating elements on the barrel for pre heating You dont need them after the press has run for a while So you may even want to go down that path as well
    More food for thought
    Cheers
