3.1 Description of the machine
The FRIGUS 6000 mixes sanitised air into ice cream
mix to obtain the desired overrun, cools mix with air
incorporated in it to create the viscous product
known as ice cream, and supplies sufficient pressure
to convey the ice cream to its destination through a
pipe.
In order to carry out these functions the machine
incorporates the following components:
-
a set of filters which sanitise air coming from the
compressed air supply;
- a pump which receives mix from ageing vats,
adds sanitised air, and sends the product to the
freezing cylinder;
- freezing cylinder with a dasher and blades, inside
which air is uniformly blended into the mix and
the product is cooled until it takes on a thick
consistency;
- a refrigerating plant connected to the outside wall
of the freezing cylinder to cool it down;
- an electrical system for command and control
of all machine functions.
The compressed air supply (the machine does not
include an air compressor) travels through a pressure
reducer (1) and a mesh filter (2) which separates
out any large particles; it then goes through a micro-
filter for removal of oil vapours (3) and an active
carbon filter (4) which eliminates odours. Finally,
the clean air goes through a sterilisable Teflon mem-
brane filter (5) with microscopic pores specifically
intended to stop the passage of bacteria.
The sanitised air thus obtained is let into the mix
between the first and second stage of the mix pump,
under a pressure which may be controlled by the
operator with a command on the control panel;
pressure may be adjusted to increase ice cream
volume.
