could you give me some advice how sort out the problem with coating. About 1.5 % coating tablets have the following defects: tiny uncouting (white) spots into logo and on the edges of tablets. We tryed working with different parameters and their combinations (high or low: pan speed, spay rate, atomising and spray pressure). It didn’t make sense. Сomposition of coating suspensiion: hyprolose, titanium oxide, ferric oxide and macrogol.
thanks a lot for your answers, but it’s impossible to change the concentation of ТiO2 and macrogol and replace our coating solution to Ready made film coating materials
