G. TANK FOR THE FLOAT
The tank has a plastic box with a float with screw of adjustment in the top that
mantains a constant level of water in the tank and with communicating
vessels inside the evaporator.
In the lid there are two sensors to control the level of water that signs to the
electronic board the presence of water in the tank.
NOTE. It is very important to place correctly the lid in the tank of the float, so
as to the sensors be submerged and can transmit an electrical signal that
confirms to the electronic board the presence of water in the tank and avoid
inopportune stop of the ice equipment.
H. EVAPORATOR (Two in model MF 61)
The evaporator has a stainless steel vertical pipe in which external side it is
solded the evaporation chamber of the refrigerant and in which in the interior
there is the axis that turns and it is mantained in axis by the action of the top
and lower treads. In the lower part of the evaporator there is a retention ring
that hermetically seals it, while in the top part there is the ice crusher
machine.
I. CRUSHING RING OF ICE (Two in model MF 61)
The crushing ring of ice is on the top side of the evaporator and it has in
models MF 22-30, two cogs to crush the ice; with its inclined shape (the back
cogs to front) compress and force the ice to come out in horizontal direction.
In the other models, the ice crusher equipment has some rectangular holes
through the ones the ice is compressed. In this way, the ice loses the excess
of water and fall to the storage in compact and dried grains.
In the crush ice machine there is a top tread, and it has two stainless steel
rolling crowns located in a way that can support the axial and radial load of
the axis.
NOTE: It is recommended to check every 6 months the state of the lubricant
as well as the upper tread.
J. REDUCTION MOTOR (two in model MF 61)
It has an asynchrounous one-phase motor with a condenser installed in
reduction gear box of gears and pinions, the reduction motor activate through
a transmission connection the axis of elevation of ice located inside the
vertical evaporator.
The rotation of the motor, subjected by two ball bearing of permanent
lubrication, transmit the movement to a fibre gear (to reduce the fluid) of it,
with a pair of gears and pinions subjected by the roller gears located in the
upper and lower extreme of the outlet axis.
The reduction gear is seal, by the presence of thw retainers installed in the
hole of rotor axis and outlet axis and it is lubricated with specific grease
(MOBILPREX IP 44).
K. MOTOR OF THE FAN (Models cooled by air)
The motor of the fan is comanded through the TRIAC of the electronic board, by the
sensor of temperature of the condenser. It works making to flow the air thorugh the
sheets of the condenser. In conditions with a low room temperature, it can
intermittently work to maintain the condensation temperature between the
pressetablished values.
L. PRESOSTATIC VALVE (Model cooled by water)
The presostatic valve mantains a contant value of high pressure in the
cooling circuit changing the water flow in the condenser. When the pressure
increase the presostatic valve interiorily opens to increase the flow of water in
the condenser.
M. COMPRESOR
The hermetic compresor is the heart of the system and it makes the
refrigerant to circulate in the refrigerator. It intakes the refrigerant as a low
pressure and low temperature steam and it transforms it as high pressure
and high temperature steam, sending it to the circuit through the discharge or
high valve.
