Corn to take over Minnedosa plant this spring

Husky’s Minnedosa ethanol plan is set ditch wheat and focus on corn during a two-month-long run this spring.

“In the next couple of months, March and April, we’re going to do a 100 per cent corn run,” said Raymond Dyck, Husky Minnedosa’s grain marketing co-ordinator. “This is the first time we have gone to 100 per cent corn.”

With a seven to eight per cent yield advantage over wheat, he said corn is the grain of choice for ethanol production.

“That is really very significant, and it’s one of the big reason’s we like using corn in our process,” Dyck told producers at the Special Crops Symposium in Winnipeg.

However, limited corn availability means wheat is also used in the production of ethanol at the plant.

The Minnedosa operation uses an average of 75 per cent corn and 25 per cent wheat throughout the year. He added that if more corn is available, the plant will use it.

During the corn harvest the ethanol plant uses about 90 per cent corn, and only 10 per cent wheat. But by August and September the ratio is at about 50 per cent for each.

However, changes in corn-to-wheat ratios can cause production difficulties.

“With the grinding and cooking step viscosity is an issue and it can trip out our equipment and the system,” said Dyck. “The thicker mash does slow down the cooking, so having a quick switch from one type of grain to another can cause issues with our electronically controlled equipment.”

He expects the 100 per cent corn run this spring will give an opportunity to see how equipment performs, and gauge the exact benefits of using a higher-efficiency grain during production.

“We want to see just how much better it is with 100 per cent corn,” said Dyck.

He noted there has been a slight rise in corn production in Manitoba since the plant opened in 2008.

According to the Manitoba Corn Growers Association, 192,000 acres were planted in 2011, up from 168,650 in 2010.

“I think we would have seen more last year, except that the wet spring really hindered the planting of certain crops,” said Dyck.

The corn Husky uses must also mean strict quality standards. Dried distillers grains, the byproduct of the process, are later sold as livestock feed.

The wheat and corn Husky buys must be dry and contain one part per million vomitoxin or less.

Corn must also weigh at least 54 pounds per bushel, and wheat 58 pounds per bushel. Minor sprouting in wheat is excepted as long as the starch hasn’t been damaged.

On average, the Minnedosa plant sees 27 grain trains unloaded every day, and produces 130 million litres of fuel each year.

Overall, Canada receives a $2-billion net annual economic gain from the production of biofuels, according to a 2010 study done for the Canadian Renewable Fuels Association.
