Subject: how to get drier steam from expobar pulser..
 

hi.

just wondering if there is a way to get drier steam from my expobar pulser. it seems kind of wet and takes a bit of time to dry out  and shoots a bit of water when i bleed before making milk.

can i adjust the ratio of steam/water in the boiler somehow?

i am in salt lake city approx 4500 ft above sea level. does this change anything?. like my machine is calibrated at a lower sea level now its higher and somehow its not calibrated.

thanks for your help.

jon

Some water out of the steam wand at the start is normal.. that is why you bleed it off. This is steam that has condensed inside the supply tube /wand since you last used it. As for drier steam.. most of the variables are set at the time that the boiler is designed. To the end user, you might have some success by increasing the boiler head space i.e. lower the normal boiler water level. I haven't owned a pulser, but there is probably an autofill sensor adjustment at the boiler, one of the first things I adjusted when I acquired my Cimbali. Also make sure that you are purging the wettest steam.. don't just get rid of the condensed water, but bleed it for another 5 - 10 seconds. Then wait a short time for the boiler to recover & do another bleed. Now you should have dry steam & be that much closer to microfoam.
