Product applications

Production line for eye ointment

When manufacturing eye ointment, it is imperative to ensure that the product which consists of several components is mixed optimally and, above all, that it is sterile. For this purpose, it includes a vacuum process system including two sequentially switched mixing tanks with speed controlled agitators. Their task is to mix the fully automated inflowing components gently at constant pressure and to emulsify them. In order to avoid boundary layers during the mixing process and to guarantee constant and even consistency, the heterogeneous mixture at the exposed location is withdrawn from the pre-mixer and fed into the final mixer via a sophisticated pipe system.
