An intresting thing with outlet flow rate

[gary.angie]

howdy

I was doing a stripping run today on a gerber and i had removed the packing from column etc and turn of head cooling coil
strip went great , the taste was great from the rolled oats ,
But at the start i thought the still was having a hisss, i had steam coming out in surges , and big drops and blops on low wines.
I only had 23 liters in a 50 l keg , and i was adjusting the heat up and down and even had the head cooling running al over the place trying to settle this beast .
I first thought blockage,then weather as it was a hot day , but i kept trying to tune it in , thinking this never happened on the last strip.
Any way i suddenly realized that the last runs i had this copper fine mesh about 7 inches long, texture like a scrubber,inserted in the out let end of the condenser.
so i found it and inserted it and presto no steam and now a nice constant solid stream of low wines for about 3 inches and then turns to droplets as it falls.

so to those masters out there , am i creating a slight back pressure ? which stops the steam or is it replicating the column scrubbers.

what ever it is its great i could ramp the heat shut the head cooling and it just flows out ,temp holds well , and av is good .
with out the copper gauze up the end of the condenser, its like, the condenser cant handle (cool fast enough )the pressure of open path of flow from the boil.

any one have ideas or experienced this .
