For Galenika, a Serbian drug manufacturer, an important processing step in the batch production of chemical and pharmaceutical active ingredients is evenly homogenizing them into powdery filler materials.
Manufacturing active ingredient compounds is a demanding process in which mixing plays an especially key role: all powdery mixtures must meet specific requirements in terms of their homogeneity, purity, particle size distribution, and stability.
amixon® vertical mixers are uniquely equipped to handle such a demanding task. They offer considerable advantages over more basic mixing machines, including ease of operation, quick and thorough cleaning, and a wide-range of processing capabilities. But above all, amixon® powder mixers guarantee excellent mixing results.
The helical SinConvex® blade contained in the pharmaceutical mixer creates a three-dimensional flow that encompasses the entire mixing vessel without leaving any dead-space. The rotation of the blade drives the powders upwards along the periphery before gravity pulls them back down along the center of the mixing vessel. Shovel-like mixing arms comb through the powders, creating powerful radial flows within the mixing goods. Regardless of the flowability characteristics of the initial ingredients, the mixer can create ideal homogeneity using minimal energy input. Furthermore, all surfaces that come into contact with the mixing goods, including the SinConvex® blades, are jacketed in order to homogenize the materials at the ideal temperature.
amixon® engineered a vertical mixer with a volume of three cubic meters for a pharmaceutical company who needed equipment in which to distribute microfine active ingredients into tablet masses. Additionally, the mixing process needed to include moistening and drying steps.
Here is a step-by-step breakdown of the mixing process:
Efficient cleaning of mixing equipment is especially crucial in pharmaceutical production in order to prevent contamination. Not only can this impact product quality, but it is also necessary to ensure that no allergens are present. Any facility that handles bulk materials can only guarantee allergen-free processing by means of thorough wet cleaning protocols.
After discharging, the amixon® pharmaceutical mixer undergoes automated wet cleaning by means of the built-in WaterDragon® system. WaterDragon® is permanently affixed within the mixing vessel, where it emerges from behind a closure flap during cleaning, and retracts during the mixing process. The lance extends into the mixing chamber where the washing head, driven by water pressure, rotates as seven nozzles spray down the inside of the mixer.
The mixer is designed to automatically begin the cleaning process after discharge, then to empty itself of residual water, and finally to dry itself. During drying, large amounts of warm air are funneled into the mixer first through the main connection and then through the nozzle of the WaterDragon®. Once the interior of the mixing vessel is completely dry, the washing head then retracts and the closure flap seals shut, leaving the mixing vessel completely air-tight once again.
The WaterDragon® system for an efficient automatic wet cleaning
This wet cleaning device is unique in that there is only one pneumatic cylinder that triggers each movement, one after another. Otherwise, the system is entirely compact and robust. After cleaning and drying, it closes automatically. The system is also gas-tight, even if there is a vacuum or pressure build-up in the mixing room. The connection can also be configured as tri-clamp or weld neck flange.
Due to the seamless design of all component details, the mixer is guaranteed to comply with the highest hygiene standards, even with minimal manual cleaning. This pharmaceutical mixing machine is made of materials that do not pose undue microbiological risk and are furthermore compliant with GMP and FDA regulations regarding the production of drugs, kosher products, and bacterial cultures.
