STEAM INJECTION

As an optional feature, all 900 Series ovens may be supplied with steam jets for baking hard rolls, and vienna, french or other hard crusted breads. This item is also available as a kit which may be in- stalled in the field. To a baker, steam actually means an atmosphere of water vapor. Therefore, it is very important that the steam be low pressure (2-1/2 to 3 PSI), that condensate be taken from the steam line before it enters the oven, and that the steam be sufficiently saturated to give the vapor cloud effect required.

At least one quarter boiler horsepower for all large 900 Series compartment (42” x 32”) or two small 900 Series compartments (33” x 22”) is recom- mended. Several firms manufacture electric and gas fired steam generators ranging in size from 1/2 boiler horsepower upward. If the steam gener- ator is mounted adjacent to the oven, line trans- mission losses will be insignificant. If the steam source is located a considerable distance from the oven, line transmission losses must be consid- ered in determining the proper size of the steam. Please refer to the accompanying diagram for the recommended installation of the steam injection system.
