Reduction of foreign matter contamination due to vinyl booth and FFU construction! A case that achieved a certain level of effectiveness.
This is a case study that addresses foreign matter contamination occurring during the process of filling powder and granular resin materials into container bags. It was necessary to solve multiple challenges, including measures to minimize the influence of outside air, avoiding complex structures around the filling machine, and resolving issues within a limited budget. To achieve this, the area around the filling machine was enclosed with a vinyl booth and a fan filter unit (FFU), creating positive pressure only in the manufacturing environment. As a result, the construction of the vinyl booth and FFU led to a reduction in foreign matter contamination, achieving a certain level of effectiveness. Further improvements were realized through floor renovation work, which also helped suppress dust generation, and measurements confirmed a decrease in foreign matter contamination. [Issues] - Adjacent to a shutter connected to the outdoors, making it susceptible to outside air influence. - The upper part of the filling machine has a complicated structure with hoppers and piping installed. - Cracks have developed in the concrete foundation and the warehouse floor. - There is no budget for fundamental measures such as overall air conditioning improvements in the warehouse. *For more details, please refer to the PDF document or feel free to contact us.*
