Mobile Oilseed Processor Helps Farmers Make Fuel
Dan and Mark O'Brien grow canola, extract its oil, and use the oil to fuel their tractors and equipment. Dan's son, William O'Brien, and son-in-law, Dale Nelson, built a mobile processor on a 28-ft. semi-trailer that can be moved from farm to farm and produce 80 gallons of canola oil every 24 hours.

Mobile Oilseed Processor Helps Farmers Make Fuel CROPS Miscellaneous Dan and Mark O Brien grow canola extract its oil and use the oil to fuel their tractors and equipment Dan s son William O Brien and son-in-law Dale Nelson built a mobile processor on a 28-ft semi-trailer that can be moved from farm to farm and produce 80 gallons of canola oil every 24 hours In addition the processor extrudes the leftover canola meal into pellets which can be fed to cattle or used in a pellet stove
With high diesel fuel costs for their 1 000-acre hybrid seed operation the Brooklyn Wisconsin brothers first considered using soybeans to make biodiesel fuel But they didn t like the high cost of setting up the low percentage of oil in the seed the need for methanol and water for the process and the need to cook the soybean meal before it could be fed When they learned that German farmers were burning canola oil straight in their tractors it seemed to be a simpler solution plus they could save 80 cents/gallon by not having to convert the oil to biodiesel
With the help of a couple research grants William says he and Nelson spent two years researching and building the processor
The idea of a mobile processor is a really solid idea William says We think it might present a great opportunity to co-ops to rent mobile processors to farmers in the area
The processor runs off a 220-volt outlet Canola seed is augered from a 160-bu bin through a rotary cleaner across a de-stoner and into a screw-style oil press The oil flows into a settling tank and is ready in 24 hrs to pump through filters and a clarifier into a storage tank or a tractor s fuel tank The remaining meal is turned into pellets that are augered into another 160-bu holding bin Canola meal pellets have 75 percent of the crude protein value of soybeans
The O Briens automated the processor with proximity switches and voltage frequency drives and other than cleaning the settling tank and emptying the meal there isn t much labor to operating the system William says
Each bushel of canola produces about 2 1/2 gal oil For about the past 6 mos the O Briens have been running a blend of straight vegetable oil and diesel in their diesel tractors - experimenting with ratios up to 99 percent canola oil û without any engine modification at all You can get away with running a higher percentage of veggie oil in the summer when it s hot William notes But when the oil gets thicker in cold weather it must be blended down or run through a converter to lower its viscosity
To minimize wear and carbon build up in the engine a converter is really the best way to go he explains Vegetable oil is thicker than diesel fuel and needs a hot working engine to atomize properly in the cylinders With a two-tank conversion kit fitted on one of our tractors we start up and shut down on diesel but while the tractor is working we ll switch it over to straight canola oil It runs and smells great and there s no noticeable power loss
The O Briens invested in one conversion kit that cost $3 000 but believe they can make one for about $1 000 with off-the-shelf parts
Producers determine costs in different ways but William says that figuring $2 50/gallon for fuel plus the meal a bushel of canola is worth about $10
By going through the processor you re adding value and saving money William says Here diesel is $2 60 for off-road so you save a little bit on fuel plus you have free feed value Of course you have the processor set up cost to offset but that s why we made it mobile; that cost is recouped as it s rented out
The O Briens have used more than 2 000 gal of canola oil in their equipment so far in 2007 They estimate that farmers could yield over 100 gal per acre growing canola The O Briens are experimenting with spring and winter varieties as well as double cropping
While their processing unit cost $20 000 William notes that farmers could make them for a lot less using bins and equipment they have on hand They re willing to share information about their processor with others
Our primary motivation is not just to have cheaper fuel but to promote an alternative to being dependent on oil William says Running straight canola oil is the best and cheapest way we ve found to do it
Using straight vegetable oil also attracts the attention of people who believe fossil fuels are to blame for global climate change Using the oil results in a 68 percent reduction of carbon emissions compared to diesel
