The active ingredients and other medium-volume ingredients are transferred straight into Batchtainers, without weighing, from the four small feed hoppers. An electric stacker truck is then used to place each of these Batchtainers onto a container discharge base on the intermediate level. From here these ingredients are then weighed into another Batchtainer on the lower level. Thanks to the three different weighing arrangements for the major, medium and minor ingredients, the company can produce different formulations in a very short time. As a result, the system offers maximum versatility.

Mixing and Container Washing

Once all the raw materials have been weighed into a single Batchtainer, a stacker truck inserts this into one of the plant’s two container mixers. After it has been clamped in position, the mixing process starts; this takes about ten minutes, depending on the product. After mixing, the Batchtainers are moved to the capsule-filling or pelletizing lines and discharged.

Whenever the formulation is changed, or after a specified time, the empty Batchtainers are taken to one of the two container washing lines, where they undergo wet cleaning. Once dried, the Batchtainers are available for refilling.

Efficient Dosing of Active Ingredients

The second plant uses Azo’s Componenter system to dose a large number of different ingredients efficiently and flexibly. Eight feed hoppers are positioned in line on the top level of the Azo Componenter for feeding bagged goods — excipients, active ingredients and additives. A smaller feed funnel is provided for feeding pre-weighed micro quantities.

The feed hoppers have a central extraction system which is activated as soon as the cover of a hopper is opened. Dust released as sacks are emptied is captured in the extract air stream, which is routed to a central air filter for cleaning.
