Resource-saving and intelligent compacting technology from HOSOKAWA ALPINE

High performance capability in a compact installation space

The powder to be compacted during the compaction process is fed to two synchronised contra-rotating rollers in dosed amounts. Between the two rolls the powder is compacted into flakes. Afterward the flakes can be crushed by a flake crusher into granules. The product portfolio of HOSOKAWA ALPINE, one of the leading providers in the fields of process technology and film extrusion, includes several compactor models tailored to suit the individual application areas. With the C 80 Pharmapaktor, HOSOKWA ALPINE has developed a solution for especially fine and challenging powders. The machine is resource-saving and allows extremely small material quantities to be processed. HOSOKAWA ALPINE thus offers a solution to match the high demands of the pharmaceuticals industry.

The pharma specialist with the smallest roller diameter
The C 80 Pharmapaktor belongs in the product line with the smallest roller diameter offered by HOSOKAWA ALPINE. Although the roller diameter is a mere 80 mm, the machine achieves a high linear pressing force of 6 kN/cm. The roller gap width is adjustable between 0.5 and 2.0 mm, and permits compacting with almost no loss. This makes it possible, for example, to develop new applications with much less material. Above all with expensive and scarce raw materials, the savings effect makes itself very noticeable. Over and above this, the machine design permits the processing of extremely small material quantities, which in turn means that especially the pharmaceuticals industry can react to the general trend towards ever smaller material quantities.

Intelligent control unit adapts to the values of physics
HOSOKAWA ALPINE developed an innovative control unit for the Pharmapaktor C 80. This is based on the principles of fuzzy logic. Fuzzy logic is understood to mean the collection of different values during operation – for example, the linear pressing force – in real time and the subsequent analysis of data patterns during the process. From this, the intelligent control unit derives the optimum settings for various parameters, for example regulation of the roller gap. During operation, electric servo drives react extremely fast and precisely to possibly varying control commands.
