The invention provides drying apparatus including a first chamber for receiving articles to be dried and having an outlet, a second chamber having an outlet, and a fan having a fan inlet and a fan outlet, the fan inlet communicating with the outlet of the first chamber and the fan outlet communicating with the second chamber. The apparatus further includes a vacuum pump communicating with the outlet of the second chamber so that transfer of thermal energy can take place between the first and second chambers. The invention also provides a method of drying including placing articles into a first chamber, evacuating a significant proportion of the air from the first chamber and from a second chamber, evacuating water vapor from the first chamber to the second chamber, allowing the water vapor to condense in the second chamber, and transferring thermal energy from the second chamber to the first chamber.
