A modular solution for continuous processing: Coperion K-Tron's new gravimetric K3-PH feeders shall provide a flexible solution with small footprint and short changeovers.

Thanks to the use of a smaller D4 platform scale incorporating the patented and highly accurate Smart Force Transducer (SFT) weighing technology, they require significantly less floor space compared to previous models. Depending on the process and requirements, several of the modular feeders can be grouped into a cluster, for example for continuous processes such as direct compression (CDC), extrusion, wet and dry granulation, and continuous coating as well as traditional batch processes.

The modular design of this innovative feeder line simplifies cleaning and reduces changeover times. The "Quick Change" design, whereby the feeder bowl can be quickly decoupled from the feeder drive, also enables simple and fast product changes. By simply releasing two clamps, the used feeding unit can be removed and replaced with a clean one.

The three available Coperion K-Tron feeder types QT20, QT35 and QS60 (twin and single screw) can be used with the same scale and drive units. They are interchangeable, depending on the product to be fed, the required feed rates and the necessary scale resolution. For an optimal Wet-In-Place (WIP) result, every unit has an integral two degree pitch facilitating maximum drainage during the cleaning process. In addition, the feeder bowls and hoppers feature a new improved seal design for optimal product containment. The complete line of equipment is engineered to meet the rigid requirements of the pharmaceutical industry, including strict adherence to cGMP guidelines and standards as well as the use of FDA approved materials of construction. Initial industry reactions to the design include very positive comments on the use of a single gearbox for the complete speed ranges of all feeder models.
