Description

Functioning

The machine is divided into 2/3 working areas and the heating treatment is obtained by means of steam injectors.
Containers fed by the inlet conveyor enter the machine and then they are submitted to the pre-set treatment.

After the cycle has been completed, the containers reach the aligning outlet belt with variable speed on which a breaking-bridge unit is installed. This device is equipped with an alternated motion mobile bar which, in case of containers accumulation on the conveyor belt, allows to line up the containers in one way and to move them to the other machines in the line.

The tunnel technical features are variable depending on the type of product to be treated and the requested output capacity.

Manufacturing Features

  • Manufacturing in AISI 304 stainless steel
  • Heat proof-covers Inlet AISI 304 stainless steel conveyor belt with stainless steel table top chain installed on friction resistant strips, with support rollers on the return section, stainless steel containment guides mounted on supports adjustable for the various sizes of containers, head driven by adjustable speed motor and idle head
  • Transport of the containers through the tunnel by a polypropylene modular belt, with dragging system and variable speed driving by inverter
  • Regulator of treatment temperature water, complete with an electric contact which, by means of a lamp, advises the operator that the machine has not reached or is not at the pre-set temperature anymore
  • Video-graphic recorder with Smart Card for recording the following parameters: water temperature in the first two sections and cooling water temperature
  • Tanks with centrifugal pumps for hot water protected by stainless steel double filters.
  • These pumps feed the manifolds with sprayers having an high flow-rate in order to obtain the best yield and treatment uniformity
  • Outlet AISI 304 stainless steel conveyor belt with variable speed and equipped with stainless steel table top chain installed on friction resistant strips, with support rollers on the return section, stainless steel containment guides mounted on supports adjustable for the various sizes of containers, head driven by adjustable speed motor and idle head
  • Breaking-bridge unit
    Electric board in stainless steel
  • Safety device for machine stop in any case of resistance to the carpet sliding
  • Safety device for machine stop in case of too full at the outlet
  • Non-start device in case the machine has not reached the pre-set temperature
  • Stop-device in case of a lowering of the minimum pre-set temperature
  • Red alarm flash lamp signalling any anomaly and installed on the electric board top side.
