Drying and Cooling

In Takeda’s production facility the vials are filled, closed, crimped and subsequently subjected to terminal sterilisation. The 100 ml maximum vials are contained in perforated sheet cassettes about 30 cm long, 20 cm wide. Eight cassettes each are placed at 13 levels of a rack.

The steriliser is loaded with three racks at a time totalling 312 cassettes. After hot water rinsing, the racks are automatically moved, on a roller conveyor, into the drying-cooling tunnel.

Inside the tunnel, they are dried at 55 °C for 45 minutes and subsequently cooled to 35 °C for 30 minutes. The 3,400 mm long, 2,800 mm wide, 4,580 mm high drying-cooling tunnel is design to accommodate three racks.

Drying process will run with partial loads

A total of three special fans inside the tunnel provide optimum air routeing with each fan providing its own recirculating system to pass the dry air required for drying through the applicable rack / cassettes. The total airflow rate produced is about 30,000 m²/h. This way, the drying process will run smoothly with partial loads, too.

The dehumidification hardware controlling the environmental conditions is housed in a separate module which is connected to the tunnel through insulated ducts. Thus, the dried air is blown into the tunnel, passes over the vials and returns moisture-laden to the Airgenexmed module.

Excess heat from the drying systems is dissipated through a water cooled plate heat exchanger. The system is storage programmable controlled. Upon completion of the drying-cooling process, the vials immediately undergo further processing.
