6. Advanced coffee making with the pressurized basket
Making coffee with the pressurized basket is extremely easy. Whilst the kettle
is boiling you can prepare the basket and by the time the kettle has boiled you
just need to add the water, pull the shot and within 20 seconds you are all
done.
Make sure you are adding at least 10g of coffee. Less than that and you risk
damaging the screen. You can also follow the temperature guidelines listed in
section 4. The measuring spoon provided will dose approx. 7g of
coffee per level measure.
You must use the Spouts with the pressurized basket, the pressurized basket
has flow restrictor in place which is a precision stamped orifice, properly
calibrated to create sufficient back pressure to mimic extraction pressure of
around 8 bars. If you do not use the spouts you will get a very small stream of
coffee exiting the basket and it will make a huge frothy mess in your cup.
It will raise the temperature of the coffee drink enormously if you pull a dummy
shot with hot water first.
7. Pressure gauge kit - Patented
The pressure gauge kit is an optional accessory that is added to the Robot,
this enables you to measure the extraction pressure from inside the basket
itself and provides real time feedback.
A full parts breakdown is given on page 25.
The pressure gauge is permanently fixed to the bracket and then to the
female fitting on the back. A filter screen is then placed between that and the
elbow fitting on the back. The hydraulic connection to the piston is then
made with a 4mm OD FDA approved tube made by Parker Legris.
The tube fittings are called quick connect push fittings, they are simply pushed
into the fitting.
To remove the tube from these fittings you
must push down the locking collar whilst at
the same time pulling the pipe out of the
fitting. Please refer to the photo.
Please do not tamper or try and remove the
pressure gauge. The gauge itself has been
locked in place with the 13mm hexagonal
fitting on the back.
There is no need to try and remove the gauge, you may remove the elbow
fitting on the back and inspect for blockages if required.
