1.45. The model is proposed: M10 / 140-V16

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.

-

IP55 electrical system with panel with stainless steel casing

-

accident prevention protections according to CE regulations

-

supplied with use and maintenance manual
