Hay steaming - using a Happy Horse Hay Steamer

[Christmas Crumpet]

Just bought a secondhand one and will use it for the first time tonight.

How long do I need to steam a third of a small bale for to ensure all the dust has gone?

Hi make sure there is room in the chest for the hay to expand, I do half a bale at a time and it takes 40 minutes.
