hello,
i noticed something in another thread, while trying to find out what is
wrong with my brewtus (or me, operating it) and i noticed something
peculiar.
my brewtus iv vibrational pump machine is very slow in building up pressure.
i watched a number of youtube videos of people making espresso with the
brewtus, and the coffee always starts dripping within 4-8 seconds.
i measured my machine, with a blind filter. it takes 11 second for the
pump to reach full pressure (about 9.5 bar with the blind portafilter).
that's about the same time when the espresso starts flowing with coffee
in the filter.
what i would like is for other people, with the same machine (brewtus iv
vibrational pump) to repeat this test with the blind filter for me and
give me the resulting time. this could help me a lot.
i could be on the wrong trail, or i could be dealing with a faulty pump.
the answer is hopefully in your replies.
another thing i would like to know, is there any way on this machine to
shorten pre-infusion time? i've learned a bit about pre-infusion from my
la pavoni manual lever, and 8-11 seconds seems very long time. with my
lever machine, about 5-8 seconds would be right. most other machines
seem to take this same amount of time for the first drops to appear.
this could be the answer to a problem i have been struggling with for
months. or not. it depends on your answers.
so, please, be so kind and test it for me. i would appreciate it very,
very much!
thanks and have a great weekend everybody,
guido.
