maintenance:
the manufacture of the Variflex®coffee brewer has originated from
the experiences directly acquired by the users of our machines, as
a development of classic coffee brewers; the cup drink quality is
the fundamental parameter that has guided the design of this
coffee brewer, characterised by:
•constant quality dispensing cycle;
•compact and solid structure;
•easy and simple maintenance;
the peculiarity of the Variflex®coffee brewer is represented by the
fact that the brewing chamber volume is automatically adjusted to
the ground coffee quantity to make the best use of the dose; the
interaction between mechanics and software is such that every
single work phase can be actively controlled, which can ensure an
espresso, the top quality of which is constant all over the time,
whereas the doses ejected at the end of the dispensing cycle are
compact, perfectly dry and fully used up; the springs that are
responsible for instability and variability between one cycle and the
other one have been removed from the brewer and all phases have
been conceived to make the best and most homogeneous use of
the dose; ground products are guided as far as the middle of the
brewing chamber in such a way that the dose is compact and
homogeneous during the compressing and brewing cycle;
the Variflex®coffee brewer has been originally designed with a
brewing chamber, the diameter of which is 45 mm; any future
development will provide for chambers having a different diameter,
which means further flexibility in performance;
the reliability of the coffee brewer is obtained by using materials
selected for their specific features: two different steels and an
aluminium alloy represent the metal part of the coffee brewer
whereas the "plastic" part is made of materials widely tested in the
world of vending machines and of innovative materials, such as
PPA, a thermoplastic material that can support high mechanical and
thermal stresses; all components have been designed to ensure full
reliability during work phases;
the coffee brewer mounted on the machine is hit by a heated air
flow that can keep the coffee brewer at such a temperature that no
heat is taken away from the coffee water, without ageing the
components of the coffee brewer too early;
no tool is required to install and uninstall the machine; just click on
a release key to disengage the coffee brewer from its work seat
whereas the assembly, guided by two pins, is ensured by the
simple movement of your hand downwards until you hear a
fastening "click"; no electric part remains on the Variflex®coffee
brewer; no operation is required for the water supply ensured by a
quick coupling that occurs by making the same movement intended
to position the assembly in its work seat;
if removed from the vending machine, the coffee brewer can be
completely dipped in washing tanks; the upper and lower pistons
can be removed with no tools for an easy, rapid and simple
inspection;
no lubrication is required by the Variflex® coffee brewer;
the software conceived at the same time as the Variflex® coffee
brewer enables the operator to program the coffee dose ground
traditionally (time required to activate the grinder), but - as an
alternative - to determine its weight (see 06.);
