The ISO Class 5 continuous sterilization tunnel by Dhara Engineers is essentially a fully automated system that uses forced convection of filtered air through a high-efficiency particulate air filter to achieve dry heat in order to sterilize cleaned and empty pharmaceutical glassware used in the packaging of parenterals. The continuous dry heat sterilization tunnel built by Dhara Engineers guarantees that glassware is exposed to the depyrogenation temperature for the length of time needed to achieve the required decrease in end toxins, which is, at the very least, > log 3 at rated output. Dhara Engineers consistently produce dry heat The Automatic Vial sterilizing tunnel can be used independently or can be delivered ready to integrate with an easy-to-use filling and sealing machine on the downstream side and a washing machine on the upstream side to form a high-yield, high-speed parenteral product packaging line. The purpose of the drying zone in the forced conventional dry sterilization tunnel is to remove wash water from glassware. The glassware is sterilized in the sterilizing zone at 300 °C (about). In order to bring the glassware’s temperature down to room temperature, the third part has a cooling and sterilizing zone.
Operation
The sterilization and depyrogenation Tunnel or pharma sterilizing tunnel uses for online sterilization and depyrogenation of washed glass ampoules & vials. In the tunnel, glass ampoules & vials are transported through a stainless steel wire conveyor entry from automatic washing machines (non-sterile) to the outlet filing line (sterile area).
Salient Features
- Each independent filter plenum is provided with filter integrity sample ports.
- Provision for ports to allow introduction of validation thermocouples in each zone.
- All filter modules have differential pressure gauges to monitor pressure.
- Pressure switches with high and low alarms.
- When the tunnel is not in use it can be operated in night-mode to save energy while preventing contamination.
- The equipment’s conveyor belt is monitored and alarm status is activated if it operates outside the belt speed set points.
- The tunnel is provided with fully integrated ampoule / vial flow control logic to allow automatic stops and restarts of the equipment.
Process Operation of Sterilizing & Depyrogenation Tunnel
PLC Controlled and equipped with touch screen color graphics display for easy operator access to control screens, statistics, data storage and retrieval. The data management system is 21 CFR part 11 compliant. Data screens feature set parameters and current process parameters. Set parameters are stored in the form of recipes which are password protected and can be uploaded to current status as and when new types of glass containers are being processed.
