The automatic thermoshrinking oven model FT55 is a device which uses a single workstation to package products through thermoshrinking.
The film is thermoshrunk on the product by a ring like gas oven. All automatic and manual use and maintenance functions are controlled by a PLC.
The operator’s presence is sometimes necessary to see that the product to be hooded enters the machine correctly.
MACHINE COMPOSITION
The standard machine consists of the following main groups:
Bedplate
Structure made of bent and painted sheet metal which supports all the machine parts, as well as the accident prevention protections and branch boxes for connection to the control panel.
Thermoshrinking arch
It moves vertically, it is driven by an inverter controlled motor and is supported by four sturdy chains. It also carries the four hot air burners, the gas distribution and regulation for each burner, the electrical parts which control gas lighting and the flame control.
Hot air burners
Each one of the linear burners is enclosed in a stainless steel chamber. The burners are designed in such a way so that the film is heated indirectly by a hot air flow and so they may work with methane, butane or propane gas at a steady machine feeding pressure ranging between 170 and 200 mbar. They only require a simple initial adjustment to go form one type of gas to the other. They are constructed with galvanized sheet, while the parts coming into contact with the flame and with high temperatures are made of high quality stainless steel.
