Rheavendors Group barista XX, Installation And Maintenance Manual

Page: 11 / 49

Barista can produce a drink called Latte Macchiato, composed by
milk and coffee and served in the cup in differently coloured bands,
typically milk, coffee and milk;
to get this special drink, refer to a specific package of instructions,
every step of which is called “LM dispensing cycle”; please keep in
mind some general principles to achieve this special drink quality:
- the first milk dispensing cycle shall not be too much mixed;
- the second milk dispensing cycle should occur after 10/15
seconds; mixing shall be extended and performed at the
maximum rotation speed of the impeller;
- the espresso coffee should be dispensed at least 15/20
seconds after the second milk dispensing cycle in the cup;
the data supplied by the table provide for a “latte macchiato”
dispensing cycle and they can be adapted to achieve dispensing
cycles more suitable for the users’ wishes;
