Description of the controls – Figure 5.1
Emergency
The machine shuts down completely if the emergency
stop button (12) is pressed.
(Mix) feed pump
The illuminated switch (2) is turned clockwise to
turn on the feed pump, and will light up. The display
(3) indicates the rate of flow of the pump in l/h of
mix. Speed may be controlled using the
potentiometer (4).
Dasher
The illuminated switch (5) is turned clockwise to
turn on the dasher, and will light up. The ammeter
(6) displays the power consumption of the dasher
and therefore the hardness of the ice cream – on
reaching maximum consumption the hot gas device
is activated at 100% until power consumption drops
to normal levels. If power consumption continues
to rise notwithstanding hot gas activation, the
refrigerator compressor is shut off. This prevents
excessive hardening of the ice cream, which could
stop the dasher. When the dasher is stopped the
hot gas device comes on for 30 seconds to prevent
ice from forming in the cylinder.
Refrigerator compressor
Illuminated switch (5) is turned clockwise to turn on
the refrigerator compressor, and will light up. Switch
(5) is active only if the dasher is operating.
Hot gas
As mentioned earlier, the hot gas is activated
automatically on excessive input or shut-off of the
dasher; in the former case until power consumption
is reduced, and in the latter case for a fixed time of
30 seconds. The hot gas device can also be activated
manually with the potentiometer (8) to reduce ice
cream hardness.
Overrun control
The illuminated switch (1) is turned clockwise to
turn on the compressed air intake to the supply pump
and will light up to indicate activation. Pneumatic
regulator (2) is used to set the pressure – read on
