High-care big-bag filling line for milk powder
Client: a Dutch milk powder producer of top quality baby and toddler food and one of the largest suppliers of baby milk powder in the world
Project: a new high-care big-bag filling line
Project
Sanitary big-bag filling line with accurate weighing installation for baby milk powder, including shuttle transfer system for discharging big-bags from the high-care (clean room) to the low-care section via an airlock. Placing the big-bags on pallets takes place outside the sanitary room.
The complete line must comply with the applicable EHEDG and ATEX regulations. The stringent hygienic requirements demand special attention to avoid bacterial risks and prevent product contamination. In addition, all parts must be easily accessible and easy to clean.
The client has chosen TBMA for this project because of our expertise and experience with the engineering, installation and commissioning of comparable sanitary big-bag installations.
Data
- Big-bags: 600 -1,000 kg, with inner liner
- Product: Baby and infant milk powder
- Filling capacity: 14 big-bags (FIBCs) per hour
- Lifting capacity: 1.500 kg
Solution
TBMA has developed an integrated filling line in which big-bags are filled and weighed and then transported from a high-care to a low-care room. These spaces are separated by a double airlock.
Each big-bag is hung with the loops on the easily accessible self-releasing hooks, after which the filler hose is connected dust-free by an inflatable. The filling accuracy is achieved by an ultrasonically vibrating metering valve. Because they are filled suspended, straight and stable big-bags are created.
The entire installation is suitable down to every detail for dry cleaning between product changes within an acceptable timeframe.

Update
In addition, we realised an update of the above project. The filled big-bags were sometimes stored for a longer period of time, which created the risk of product degradation. For this, the client switched to special big-bags with a gastight inner bag.
TBMA has adapted the installation in order to achieve airtight multiple hot sealing of the big-bag liners. The bag is vacuumised by using a special valve in the big-bag liner and then injected with nitrogen. This way the shelf life of the product is significantly extended.
