The selection of the proper feeder and configuration is a determining factor for achieving optimal results in tablet coating processes. Both gravimetric and volumetric feeder configurations can be utilised. However, a gravimetric design allows the exact powder quantity delivered to be validated and ensures higher accuracy.

Tube heaters have a critical impact on process results when used with temperature-sensitive media or processes. Watlow's gas and pump line heaters are characterised by their precise distribution of heating power. This is achieved firstly by adapting the watt density to specific requirements and secondly by controlling the temperature of the heaters. Together with the insulation of the heating jacket, this leads to energy savings because only the amount of power actually required is introduced into the thermal system.

At its in-house congress on "Pharmaceutical Hot Melt Extrusion"s , held on April 15, 2010, Coperion, Stuttgart/Germany, provided around 100 guests from the pharmaceutical industry with a compact overview of this special, rapidly growing application. Pharmaceutical experts from both industry and science explained, by way of case examples and the results of R&D projects, the technology and vast area of application for hot melt extrusion in the pharmaceutical industry.

A manufacturer of generic drugs operates a plant in which the ConiWitt- 150 sieve mill was integrated to deagglomerate and homogenise solids. However, since the manufacturer was also keen to use the plant for wet milling of powders, the search was on for a mill version that was suitable for both dry and wet milling. One of the customer's major concerns was maintaining the pressure surge resistance certification of the ConiWitt-150 that was already installed. The company decided to use the ConiWitt-150W on account of its modularity.

The Super Clean Mill meets the requirements of good manufacturing practice (GMP) in the pharmaceutical and food industries. The special design of this pin mill allows broad use. For processing newly developed active substances, the GMP-compliant mill is housed in a containment.
