Pam Glatt GC Smart high-speed coating machine has unique advantages in tablet coating. It was after years of research for improvement in coating process that Glatt has come out with it's GC Smart.
To fully appreciate the advantages of the new Pam Glatt GC Smart high-speed coating machine, one has to understand the process of coating, and the issues related to it. The most common method used is perforated pan coating. In this process, lot of tablets is continuously sprayed with coating solution supported by continuously rotating Pan and hot air for drying. This is a typically lengthy process and heavily dependent upon type of equipment, process parameters and even the operator skills.
One of the common problem in the above method is gun choking because of which frequent Operator intervention is required in cleaning the guns. Further during the process operator has to regularly put his hand inside for sampling and to check effective drying. Typically due to the limitations of drying the spray rates are also slow making the process lengthy. The baffle design also plays an important role from effective and gentle mixing of the whole lot.
However the biggest hard hitting problem is the loss of coating solution due to spray drying. The extent of this problem is so much that in most of the coating processes atleast 20-30 per cent solution is sprayed extra to compensate for spray drying and for achieving the required weight gain.
After years of research for improvement in coating process Glatt has come out with it's unique GC Smart. The trials have shown, that unique Air flow pattern inside the process area makes the efficiency of the system 95-98 per cent. This means solution sprayed will be effectively used for weight gain rather than getting wasted on the Pan, baffles or the spray nozzles. This itself becomes a huge saving if you compare the cost of coating solution spent due to spray drying.
Increased drying capacity will enable one to increase the spray rate and reduce the process time by almost 40-50 per cent. The specially designed GCSD spray nozzles having Anti Bearding Cap with Nano coating ensure that there is no beard formation or Gun choking. Also this GCSD nozzle can be dismantled in less than a minute for easy cleaning. The uniquely designed " Reverse Fischer Baffels " covering the entire width of the Pan ensure gentle but effective mixing.
Moreover due to the reduced spray drying the process remains clean. This enables shortest possible changeover during the intermittent lots or batches. The sample taking port ensures that operator can check the samples without intruding inside the process zone.
