Custom-designed curing system

24th January 2018

Laboratory safety cabinet and enclosure manufacturer Bigneat has installed a custom-designed and manufactured controlled environment system to answer the specific needs of a leading transfusion diagnostics company.

The company has developed an innovative diagnostic system that will allow automated blood type testing and disease screening, providing considerable clinical benefits - significant savings in testing costs and rapid results.

The system uses highly characterised antigen and antibody panels that require a critical manufacturing process. One step is the precise controlled rate of drying of a liquid solution that provides a solid protective coating.

Bigneat was tasked with coming up with a custom design for a controlled environment drying system made up of multiple drying pods, each with independent controls and constant monitoring of the process parameters. The system would be installed in a clean room environment following the strict guidelines of GMP regulations. The main criteria for the drying phase was to achieve a curing time of three to four hours per pod.

The system Bigneat designed and manufactured has 12 independently operating pods, each provided with uniform, very dry clean air and with fully automated operation. A regulated dehumidifier and cooling system develops the controlled dry atmosphere and the system features advanced electronics that constantly monitor the environment parameters and boasts a large MMI touchscreen control panel for ease of operator use.

The collated process data is stored in the memory of the PLC controller, which has direct connection with the company’s manufacturing execution system (MES) to transfer and store critical data such as manufacturing recipes and alarms.

Commenting on the system development Bigneat’s General Manager of Containment Solutions, Stephen Pratt, said: "We worked closely with our client every step of the way to design and supply a fully operational solution, it’s been a challenging and enjoyable process”, he adds "We are increasingly being asked for special designs to solve customer specific process needs and it's one of the most enjoyable aspects of what we do.”
