Steam Wand Overview
The Xpress has an optional steam wand feature. The steam wand can
be used to steam liquids that cannot be run through the machine (e.g.
eggnog, soy or flavored milks).
There are two types of steam wands available: the manual steam wand
and the automatic steam wand. The manual steam wand uses a knob to
control the flow of steam and the automatic steam wand has a touch pad
for selecting the temperature and type of steam.
Automatic Steam Wand
The automatic steam wand allows a customer to select the heat and type
of steam for their drink.
Automatic Steam Wand Theory of Operation
When a steam wand selection is made, steam will begin to flow through
the wand and the system will begin to monitor and display the milk
temperature. The temperature is displayed on the top line of the Xpress
machine display.
When a frothed selection is chosen, air will be introduced near the tip of
the steam wand to produce frothed milk.
When the milk reaches the preset temperature the steam flow will
terminate.
If steam wand operation and automated milk beverage are
simultaneously selected the automated milk beverage will be created
and the steam wand will be disabled.
The steam wand function will allow automated coffee and espresso
production to occur simultaneously.
The system is capable of producing three temperature selections for both
steamed milk and frothed milk
