| titleOfInvention | Method for producing granular coated sodium percarbonate and product obtained according to said method |
| abstract | The present invention relates to a process for the preparation of coated granular sodium percarbonate having a low TAM value. Sodium percarbonate is prepared by fluid bed granulation at a temperature (T G ) 45 to 75 ° C. and coated by spraying in a fluidized bed of an aqueous solution comprising at least one coating component at temperature (T U ) 35 to 100 ° C. According to the invention, after fluid bed granulation and before coating, an additional drying step is carried out at a temperature T NT (T NT > T G ) (a) or fluid bed granulation is carried out in at least two steps at temperatures T G1 , T G2 And running at T Gn (T G2 or T Gn > T G1 ) and if two-thirds of the granules are formed at T G1 , no additional drying step is required (b), or further drying step after granulation It does not carry out, but after coating | coating, ie, T UNT (T UNT is 20 degreeC or more higher than T G ). |
