Automation dedicated to sterilization systems with ethylene oxide
AUTOMATE THE STERILIZATION PROCESS WITH ETO IN COMPLIANCE WITH THE CRITERIA THAT REGULATE IT AND THE EXPECTED PERFORMANCE, AIMED TO OBTAINING A CONTINUOUS CYCLE
The process is divided into 3 phases:
- • Pre-heating;
- • Sterilization;
- • Degassing.
Lots composition:
- • 32 Europallets;
- • 24 US pallets.
Initially a single line, consisting of 3 sections: pre-heating tunnel, sterilization autoclave, degassing tunnel; approximate length of each section 16 meters.
In the two years following the installation of the first line, 3 more lines and an automatic warehouse for the process of second aeration, storage and formation of outgoing orders have been added.
Each line is equipped with 2 single bays side by side, sturdy and equipped with guides to allow the simple deposit of individual pallets by fork lift. Immediately after deposit, the pallets are measured.
The positive feedback of the measurement allows their moving on the conveyors installed inside the preheating tunnels.
Here the batches are formed: on the basis of their quantity and type, the pallets are spaced at fixed measurements, which is an essential requisite for the success of the sterilization process.
Once the batch has been completed, the tunnels close and the pre-heating cycle begins, at the end of which the autoclave will open.
A system that does not require any modification within the autoclave allows the entire batch (consisting of 32 EU or 24 US pallets) to pass from the pre-heating tunnel to the autoclave.
Keeping unmodified the planned interspaces between the pallets, they are transferred in less than 70 sec.
The autoclave can close again and the sterilization cycle begins, while another load can be set up in the pre-heating tunnel.
At the end of the autoclave cycle, once the autoclave doors and the degassing tunnel are open, the entire lot is transferred from the autoclave to the tunnel, as happened during the loading phase.
While the degassing cycle begins, a new batch occupies the autoclave.
At the end of the degassing cycle, the pallets leaving the 4 lines are sorted by a double shuttle on a transport line, where the successful outcome of the sterilizing and dimensioning process is checked.
The pallets are then transferred in a automatically handled warehouse, in which the aeration or degassing take place at a constant temperature of 50 ° C. The lots retain their composition, as the pallets are placed at a distance from each other.
Storage takes place in depth and in height.
The building is divided into 3 sections: two dedicated to aeration, the last one to storage and creation of outgoing orders.
Each section has 4 floors, 12 lanes for 8 EU or 6 US pallets (384 EU or 288 US per section), for a total of 1152 EU or 864 US pallets.
