The French company SERAC has just introduced a new type of RABS isolator (Restricted Access Barrier System) to the market to optimise the conditions for aseptic filling of milk and beverages in sterile or sterile areas. With this device, 72 hours of continuous filling can be produced, eliminating the need for disinfecting procedures on the way, thereby increasing productivity while ensuring safety.
Compared to traditional isolation devices, there are three major improvements to the new SERAC device (but the benefits of traditional devices that are already known are preserved in the new device):
• One-way flow Unlike traditional isolators, the RABS device is not completely enclosed, but is an aerodynamic barrier caused by positive pressure in the operating room and protects the sterile vessel. The circulation direction of filling is vertical one-way circulation, and the circulation speed can be controlled so that the air can be continuously circulated and updated. Through the joint use of the two technologies, the presence of particulate matter in the operation room can be eliminated and contamination from the outside can be prevented. While avoiding complete containment, continuous air circulation extends the time of aseptic conditions and can be produced continuously for 72 hours without the need to stop work for decontamination.
• Barrier area The sterile area is surrounded by a barrier area, and the barrier area is also under the control of one-way circulation. The barrier zone is just like an auxiliary protective barrier between the operation room and the rest of the workshop, which facilitates the cleaning and maintenance of the machine.
Easy access The heart area of ​​the machine, the aseptic operation room, can only be accessed during the production by means of a glove box located at the critical part of the filling machine. However, all other parts—product handling stations, production line entry points—can be accessed through external doors, and entry personnel do not have to wear sterile room type clothing. All entries and exits in the barrier area are registered to ensure that the operation has good tracking performance.
