process air drying in pharmaceutical productionDuring drying and processing sensitive and mostly expensive active ingredients and auxiliaries in the pharmaceutical industry, constant and precise process conditions, including the moisture content and the temperature of the process air, are more important than in many other industrial sectors.

Changing air conditions, be it due to changing environmental conditions, production processes or periodic switching cycles, can quickly lead to quantitative and qualitative losses during production and product quality. Such control deviations or fluctuations occur above all when using simple control systems such as thermostatic or hygrostatic two-point controls, but also with simple continuous control systems.

Based on this experience, a control system for adsorption drying systems was developed for ULT Dry-Tec, which records the state of the sorption wheel (temperature, speed, water content) with the help of numerous measuring points within the system and, based on these values and several independent control variables, optimally adjusts to changing environmental conditions. resp. process conditions reacts. It could be determined that the energy requirement and the reaction time of the systems as well as the system wear can be reduced through a process-adapted operation mode.


Do you have a specific application or would you like to find out more details about the use of a system for process air drying? Contact us - we look forward to your message.
