In order to enable the packaging-free purchase of highly viscous foodstuffs requiring refrigeration (such as dairy products), the Kempten University of Applied Sciences developed a dosing dispenser for this area of application and built it with the aid of additive manufacturing processes. The main requirements were to ensure functionality, i.e. sufficient cooling capacity and reliable, hygienic dosing of the products to be filled, as well as easy handling by the customers. Furthermore, a modular system was to be developed that would allow different product categories from quark to yogurt to be filled. With the equipment concept developed for this purpose, different configurations can be flexibly combined and easily exchanged via a modular system. Scalability of the product chamber was also demonstrated by developing a series.
Following a proof of concept, a virtual prototype of the food fill system was created and optimized. Based on this, a physical prototype was successfully realized and presented to potential target groups in field tests. In these user tests, both the required functionality under real test conditions and the acceptance by the respective target group were successfully confirmed.
