Functioning
Tunnel designed for the continuous thermal treatment of glass jars/bottles, PET containers or tin cans containing products which require PASTEURISATION (fruit, pickles in oil/brine, creams, paté, sauces, etc.) or hot-filled products which must be subjected to an initial phase of INLET TEMPERATURE KEEPING and then to COOLING (jam, ketchup, etc.).
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 convey them to the other machines in the line.
The thermal treatment cycle varies according to the type of product and the containers dimensions.
Also the machine’s 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
Heat exchanger of tube bundle type, complete with by-pass, modulating valve, manual valves, filter, condensate discharging device and safety protection system in stainless steel
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: pasteurisation water temperature, pre-cooling water temperature, pre-cooling water temperature regulation
Tanks with centrifugal pumps for hot water in the different thermal treatment sections, 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
Steam self-locking device in any case of machine stop to avoid the product exposure at high temperature over the pre-set time
Red alarm flash lamp signalling any anomaly and installed on the electric board top side.
On demand the machine can be supplied with:
Stainless steel MANIFOLD for feeding water to the machine tanks.
Stainless steel MANIFOLD for collecting and piping the tanks discharge water to one point.
Containers DRIPPING BLOWING UNIT.
