A steam dispersion system including insulation is disclosed. The steam dispersion system may include a steam dispersion tube with at least one opening defined on an outer surface of the steam dispersion tube and a hollow interior. The insulation covers at least a portion of the steam dispersion tube, the insulation defining an opening aligned with the opening of the steam dispersion tube, wherein the insulation meets 25/50 flame/smoke indexes for UL723/ASTM E-84 and has a thermal conductivity less than about 0.35 Watts/m-K (2.4 in-hr/ft{circumflex over ( )}2 deg F.). A nozzle defining a throughhole may be placed within the opening of the steam dispersion tube, the throughhole being in fluid communication with the hollow interior of the steam dispersion tube to provide a steam exit.

A steam wand for coffee machines is provided with a steam dispensing head that is centrally provided with a blind axial conduit that feeds one or more dispensing nozzles that end on the outside of the head and are provided with a tangential sloping direction with respect to the cylindrical conduit.

The present invention is a froth wand for an espresso machine that can generate a high velocity stream of steam to foam a beverage at the beverage brewing apparatus. The wand includes an adapter for attaching to the beverage brewing machine at a steam supply outlet, and a conduit for communicating the steam to a steam tube. The steam tube has a cylindrical body with an annular recessed exit, and is surrounded by a cylindrical sheath. The sheath includes a cylindrical plug with a small longitudinal aperture that fits into the outlet of the steam tube. The mating of the sheath's plug and the steam tube forces the steam through the aperture, accelerating the steam at the exit.
