Kyabram CFA captain Tom Druggan said the CFA was alerted to the blaze at 256 Allan St at about 10pm when a member of the public noticed smoke coming out of the building.
Within six minutes, three fire trucks from Kyabram, two fire trucks from Tongala and an aerial pumper were deployed to the blaze.
The fire was brought under control within five minutes, and the aerial pumper was not needed, Mr Druggan said.
Mr Druggan said an early-stage investigation had concluded that a dryer in the southern end of the building was the source of the flames.
Nobody was inside the building at the time of the fire, and no-one was injured while putting out the fire.
