•
Conveyor belt washing system. Fully automatic system
• Electric control panel. Houses all centralised
system controls.
The
floor of the chamber is made of stainless sheet steel
AISI 304. The construction of the floor is water-tight
and has raised edges along the perimeter to enable washings
to be collected and channelled; in addition, it is fitted
with a centralised water drain.
The perimeter and roof structure of the chamber consist
of a removable, self-supporting framework of stainless
steel tubes.
The side walls and ceiling consist of a modular, double-wall
stainless steel sheet panelling that is thermally insulated
with self-extinguishing polyurethane foam.
Each panel is provided with metal frame so it can be screwed
onto the load bearing structure. The chamber ahs side
hinged doors to allow full access for chamber cleaning
and maintenance.
The air treatment, air conditioning system
consists of a number of electric fans that are installed
internally and force the air on to the product. The air
heating system uses an electric battery with armoured
resistances.
The conveyor belt is placed inside the
chamber, where it provides continuous conveyance of the
dough pieces throughout the leavening process.
For each individual proofer, belt length and width is
defined according to client’s production needs and
on the basis of the leavening times necessary for the
specific type of dough. The belt in the chamber can have
the configuration of a spiral path arranged on one or
two winding drums, depending on belt length.
Product requirements and properties are taken into consideration
when choosing the most appropriate material for the belt
and the most suitable weft configuration for the surface
on which the dough balls are to be placed. This is done
in order to avoid that, during the leavening process,
the surface of the dough that is in contact with the belt
is deformed by the meshes.
Conveyor belt speed can be adjusted within a given range,
depending on machine type. Belt speed data appears on
the digital display located on the electric control panel.
The
automatic belt washing system is placed externally,
in the product loading area and consists of a ramp of
spraying nozzles fed by a high pressure electric pump.
Electric
controls include all the accessories required
to assure full automatic control and operation of the
procedure.
