Abstract
Abstract A steam pressure unit for cooking food and the like with dry steam includes a double wall at one end which serves as a manifold for feeding steam pipes which then distribute the steam at uniform pressures to the interior of the unit. The manifold also serves as a separator, with condensate which collects in the manifold draining from the manifold through a condensate valve into the interior of the unit for removal therefrom through a drain valve.
