Introduction
DESCRIPTION:
The ST10-2G series steamer is a pressureless steam
cooker consisting of two independently controlled compartments enclosed in a single cabinet. Each compart-
ment is equipped with a separate heavy duty door with
inner gasket plate isolated from the exterior surface. Door
latches operate by action for positive sealing of inner
door. Operation controls are displayed on a single frontmounted panel and include separate timers with indicator
lights for selection of constant steam or 60-minute-long
duration cooking. Two gas red, stainless steel generators operating at “0” psi (0 kg/cm2) and rated at 95,000
BTU are located in the bottom cabinet and may be operated separately.
BASIC FUNCTIONING:
The steamer may be operated with only one compartment in use; or both may be used simultaneously. Each
compartment is equipped with identical controls, allowing
selection of constant steam or 60-minute timer operation.
The cooker becomes operational when it is set to constant steam, or the timer is set at the desired cooking time
and the compartment door is closed.
When steam owing inside the compartment has raised
the interior temperature to 195°F, the contacts of a thermostatic switch close, completing the circuit to the timer
motor and starting the cooking time period. At the end of
the set interval, timer contacts switch to shut off the cooking operation and sound a signal buzzer. The buzzer is
silenced by returning the timer dial to the OFF position. In
the constant steam mode, operation will be continuous.
Steam emitted from the compartment along with liquid
cooking drainage is directed through a drain screen inside
the compartment into the cooker drain line to the generator drain box that is automatically actuated by a thermostatic cooling valve to condense the steam to water prior
to discharge into the oor drain.
