General Characteristics
 TUNNEL VARIETY: In order to clean,
rinse and dry in very short cycles that can-if wanted- become
part of the continuous line of production. Any of the steps
can be skipped according to the client’s need.
BATCH VARIETY: In batches, with the same characteristics,
washing, rinsing and drying are done in short cycles.
 They are made of a stainless steel pleated sheets on which a
wire mesh or stainless steel chain conveyor belt is found. There
are lateral rails made of the same material. Inspection lids
on the top and side are thermally isolated, as are the spare
water tank, the pump, speed reducer, water filter, regenerative
turbine and electric switchboard.
The size of the tunnel is determined by the client’s type
of production. Standard sprinklers are used but they are  specific
for the needs of the parts to be treated. The supporting structure
is made of stainless steel tubes and can be removed for maintenance
purposes. The conveyor belt zone has areas that drain into a
collecting tank that is oriented towards the drainage system
to favor the gathering of water in the recycling tank.
FILLING
AND DRAINING: Filling is carried out using a solenoid valve
with electronically controlled maximum and minimum levels. Drainage
is done through a spherical valve.
 HEATING: Water is heated using shielded stainless steel
resistors, located in the compensation tank. The heads of the
resistors are covered by a stainless steel protection box. The
temperature is digitally controlled.
SPRAY: On the top, a removable lid allows clear view
of a dismountable container to which the sprinklers are connected.
MAXIMUM-MINIMUM LIQUID LEVEL SENSOR: It is located inside
the compensation tank and using a double float system, it can
send the information to a solid interphase located on the switchboard
and from there to the solenoid valve.
SOLIDS IN SUSPENSION: These are removed using a filter.
The cleaning fluid circulates thanks to a centrifugal pump adequate
in flow capacity and pressure according to the job to be done.
GENERATION AND TRANSMISSION OF SPRINKLER FLOW CAPACITY:
The size of the compensation tank is determined by the flow
capacity. The pump will then take the liquid from there and
will send it through the sprinklers and into the tunnel according
to the custom made design.
 HOT-AIR
DRYING: The size of
the drying tunnel is determined according to the client’s
needs. It is made of stainless steel and the conveyor belt area
has drainage into a collecting tray that has a flexible pipe
leading to the water tank. It has double walls and is thermally
isolated by a ceramic blanket.
PRELIMINARY DRYING: This is carried
out by a medium to high flow of air produced by turbines directed
by air flow direction flaps towards the parts to be dried.
HEATING: This is done by a centrifugal
fan connected to heaters that are connected in turn to a tunnel
type air flow direction flap that we manufacture. Thus, the
air is directed towards the parts that are to be dried. The
temperature is controlled by a sensor.
TRANSPORTING THE PARTS: The parts are transported by
a wire mesh or stainless steel chain conveyor belt with lateral
rails also made of the same material. It is connected to a speed
reducer that provides the adequate ratios and power. All along
the belt there is a removable stainless steel rail.
CONTROL PANEL: The control panel is located in a box
attached to the device. The switchboard is manufactured
according to ISO norms and works with 24V. The switches
include an on /off switch for the pump, the conveyor belt control
switch (on/off and speed control) thermostat and liquid level
indicator lights. |
