|
General
Characteristics: |
||
|
- |
Base composed of
a sturdy tubular and angular structure of acc .
stainless steel AISI 304, with leveling feet in acc .
stainless |
|
|
- |
External casing
constructed from polyurethane foam panels (120 mm thick), covered with acc . stainless steel AISI 304. |
|
|
- |
Conveyor belt
composed of a frame in sections and central guides in polizene ; containment
side rails in shaped sheet metal; the net is built with V-shaped links and
side chain, the whole is in AISI 304. Network carpet
dimensions: 1000xlung.attile width 8000 (+400 supply side). |
|
|
- |
The belt is
driven by a gear motor ( PE KW 1.1) controlled by an
ITACHI inverter, the crossing time of the product is
variable according to the type of product. |
|
|
- |
The ventilation
system is provided by 12 fans of 330 and 400 mm
diameter placed on the ceiling. |
|
|
|
These fans are
driven by motors ( PE cad / KW 0.75), |
|
|
|
all protected
by aluminum sleeves, which support the guide bearings |
|
|
- |
The lifting of the
casing (for inspection and cleaning of the tape) is allowed by four angular
transmissions with trapezoidal screws , driven by a
single gear motor ( PE KW 1.1) placed under the
base. |
|
|
- |
the injection
and regulation system of the cryogenic gas, is realized through nozzles
calibrated sprayers, placed on special ramps connected to two solenoid
valves. |
|
|
|
All this is
controlled by a PLC using a PT100 thermoresistance . |
|
|
- |
The exhaust gas
extraction system is allowed by an aspirator placed on one shelf applied in
proximity ( PE KW 1.1). |
|
|
|
This vacuum
cleaner is connected to one |
|
|
|
three-way valve
with adjustment throttle, via a flexible hose |
|
|
|
The three-way
valve |
|
|
|
it is placed
above the tunnel on the supply side. |
|
|
- |
The electrical panel
consists of an acc . INOX, where they are assembled
all electrical equipment and the PLC, which programs the entire cycle of
pre-set freezing based on the characteristics of the product being processed. |
