The Berlin premix factory was built with the aim of a high level of automation and at the same time a high level of flexibility. As a premix contract manufacturer, the customer must be able to produce a variety of premixes with short product change cycles.
The main components are stored in 1 flour silo, 1 big bag station and 14 small silos and are automatically dosed and conveyed to the mixers. Small components (micro ingredients) are stored in a manual ingredient weighing station with 40 containers and weighed according to the recipe. The weighed micro ingredient batches are tipped into a dumping station, from where they are vacuum transported into the mixers.
2 horizontal mixers (paddle mixer and plowshare mixer) are operated alternately. When changing products, the mixer used also changes to the second mixer. This enables a quick product change because the mixer can be cleaned in parallel and a mixer for a different product is always available.
After the mixing process, the premixes/mixtures are filled into regular bags (eg 25 kg) and big bags.
