Slow Press Makes High-Quality Oils
The made-in-Wisconsin M70 oil press makes soybean oil that can be burned in a diesel engine as well as sunflower oil that can be poured on a salad. You can run practically any kind of seed or nut through to get a food-grade oil and a high-protein meal. The secret is in the way it works.
“Our expelled oil comes out between 90 and 120 degrees, well below the 138-degree limit for cold pressed oils,” says Ryan Thomas, OilPress.Co. “Anyone who farms can process their own commodities and extract the oil to use for medicinal, cooking or soap making purposes, anywhere vegetable oil is used.”
Thomas explains that soybean oil produced at higher temperatures by most conventional presses starts to polymerize. Before it can be used as fuel or for most other purposes, it has to go through a toxic chemical process to break up the polymers.
“Cold press soybean oil is very low viscosity,” he says. “It can be used directly in a diesel engine.”
Finding a farm-scale oil press is what got Thomas into the business. Prior to 2001, he was selling a multi-oil combustion system he had patented to farmers who were burning oil they pressed from their soybeans.
“They were using European, farm-scale presses built to handle canola and sunflower seeds,” says Thomas. “They were destroying them on soybeans.”
A mechanical engineer since 1990, Thomas set out to make a better press. “I could see why the European presses failed, so I set out to build one that could handle soybeans,” he says. “In the 20 years since, I’ve sold more than 3,000 worldwide.”
He has continued to improve the design. The M70 has been in its 5th generation for 3 years. With it, he doubled the size of the bearings in the chain drive. That allowed him to offer a full 5-year warranty on the $9,840 oil press.
“Our oil press will produce 50 to 70 gal. of oil a day,” says Thomas. “That’s 1,500 to 2,100 gals. per month with most oilseed crops.”
The M70 is rated at 700 lbs. in 24 hours. It’s engineered to run 24 hrs. a day for months on end without intervention. It draws only 4 to 6 amps under normal operation. In a 24-hr. period while crushing soybeans, it used 21.3 kWh, roughly $2 a day in most communities, estimates Thomas.
“The fact that it’s a value-added process appeals to me,” he says. “I have one customer who leases his canola and sunflower seed oil to the local school district to use in their kitchen. At the end of the week, he takes back the used oil and extracts it for diesel fuel.”
Clay Oliver, Pitts, Ga., operates several of Thomas’ oil presses. He uses them on everything from sunflower, sesame and pumpkin seeds to coriander seeds, peanuts and pecans. In addition to oil sales, he dries and grinds the meals to make specialty flour. His specialties include pecan oil at $17 for 8 oz. and pecan flour at $10 a pound. He even processes okra into oil and meal.
In recent years, Thomas has seen a rising demand for his presses for use with hemp seed. He sees tremendous potential for the hemp oil, noting that his Canadian customers report producing from 150 to 300 gals. of oil per acre. It’ll burn directly in diesel engines.
“I have one customer who makes a health supplement with hemp oil,” says Thomas. “She sells it for $30 per fluid ounce. That’s $3,840 per gallon.”
While OilPress.Co does have some dealers, 99 percent of his sales are direct. “The machine is so simple; it doesn’t require a dealer to set it up and teach a person to operate it. If you can make a smoothie with a blender, you can operate our press.”
Thomas also sells a centrifuge oil cleaner to remove contaminates down to one micron as well as water. Made completely of stainless steel, it’s easy to use, easy to clean, and produces a food-grade quality oil.
