French SEAC Company recently introduced a new type of RABS isolation device (Restricted Access Barrier System) to optimize conditions for the aseptic filling of milk and beverages in the sterilization or sterilization zone. 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 with the traditional isolation device, the new device of SERAC company has three major improvements: One-way flow: Unlike the traditional isolation device, RABS device is not completely sealed, but a high pressure caused by the operating room Aerodynamic barriers and protection of sterile containers. The flow direction of filling is vertical one-way circulation, and the circulation speed can be controlled so that the air can continuously circulate and update. 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 loops prolong the time for aseptic conditions, allowing continuous production for 72 hours with no need to stop work for decontamination. Barrier area: The area around the sterile area is 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 operator room and the rest of the shop, facilitating the cleaning and maintenance of the machine. Easy to access: The heart 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 and production line entrance and exit points can be accessed through external doors, and entry personnel do not need 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.
