Enables moving the display cursor upwards.
2 - HOSE SPRAY KEY
Pressing this key opens the timed passage (3 minutes) of the washing water in the manual hose spray.
The water flow is controlled by an hold-down lever of the tap.
3 - ARROW KEY
Enables moving the display cursor downwards.
4 - STIRRER KEY
When pressed it starts the stirrer functioning without heating or cooling phases. It is always active except
when the automatic cycle is started or during the refrigerator phase.
5 - CYCLE START KEY
Pressing this key starts the automatic functioning cycle.
6 - ARROW KEY
Enables moving the display cursor upwards.
7 - ENTER KEY
Enables confirming the command selected in the chosen menu.
8 - ARROW KEY
Enables moving the display cursor downwards.
9 - REFRIGERATOR CYCLE KEY
Enables immediately starting the refrigerator cycle without waiting for the times provides by the automatic
cycle. It is also active when not in cycle and enables reaching the permanent temperature of 4÷6 °C, at least
for as long as the START button is on (machine electrically powered).
10 - STOP KEY
Stops the cycle and brings the machine back in stand-by, without guaranteed temperature specifications.
4.1.2
Operating phases
The MIXPASTO 60/120 is intended for the pasteurisation of mixes for ice cream with heating and cooling
cycles controlled by a micro-processor programmable by the user.
The machine provides the following operative treatment phases for the ice cream mix:
1.
pasteurisation
2.
emulsifying
3.
cooling
4.
preservation (maturation)
Emulsifying happens by increasing the stirrer speed in view of the product temperature and by making the
product bang against the metal elements of a specifically designed grid.
The stirrer speeds are pre-set. There are normally 2 speeds set during heating and 2 during cooling; the
speed automatically changes when the mix reaches 55°C, both during heating and during cooling.
The user can request the setting of 3 speeds both during heating and during cooling, from the manufacturer's
Technical Service.
The stirrer speed is further reduced during preservation and it automatically intervenes for 1 minute at
intervals of 20 minutes.
The user can ask the manufacturer's Technical Service to set the functioning times of the stirrer during
preservation differently.
The operator can vary the stirrer speed at any moment by means of the LEFT ARROWS.
The cycle times in the chart of fig. 4.2 refer to laboratory tests with specific products that can differ based on
the type of mix and functioning conditions (environment temperature, water temperature, etc.).
