Thank you for visiting Walder Mfg web page for more information on the oil press system. Walder Mfg sells a small
scale processing plant for oil crops that farmers or individual entrepreneurs can purchase. The presses use a mechanical or
physical process of separating the oil rather than a chemical process. The presses work with the oil seed going into the hopper,
a horizontal extruding screw presses the seed creating extreme pressure and heat to expel oil through the front bars and cake
rings. The cake or high quality meal exits the press through an adjustable taper which the thickness of the cake determines
the pressure and heat in the press.
Rudolf diesel invented the diesel motor to run on vegetable oil thinking a farmer could be self sufficient on energy. It
wasn't until the high cost of diesel fuel and the need for clean burning diesel that BIO-DIESEL became popular again.
Why to buy from Walder Mfg, and not over the internet.
Most of the vendors on the internet don't use the presses and they can rate the presses at a higher capacity
and the buyer thinks it's a great deal when in reality you paid way to much.
Why to buy from Walder Mfg — the answer is simple —" they work" after we spend 8 to 10 hours
servicing and tweaking for your operational needs so the press performs at its optimum oil yield and longevity.
One of the biggest reasons is our technical support with your purchase you have access to all our knowledge
on running these presses for years. (We don't want to forget parts.)
We don't just sell presses we use them so every press is in working order and set up for the crop you wish
to press and the custom built machines are run before they leave our shop.
Why own oil presses
Farmers traditionally set aside 10% of their land to feed the horses. Now days, if a farmer would set aside
10% of their land for an oil crop, they would produce enough oil and protein to supply most livestock operations. For example,
an acre of canola yields 40 bushels. From 40 bushels you will make 2000 pounds of meal and 90 gallons of oil, not to mention
3 large round bales of straw and the ability to double crop, even in Wisconsin. The net gain is $560.00 per acre, which would
equal corn at $4.00 a bushel without the ability to double crop. |
