The screened initial coated core particles were placed in a fluidized bed coating machine, and vegetable oil was used as the coating material to perform secondary coating on the initial coated core through the bottom spray system of the fluidized bed coating machine.After the secondary coating, more than 40 mesh guanidine acetic acid was obtained by swinging sorting and grading screening.
The fluidized bed granulator is a granulating device developed on the basis of a fluidized bed dryer to complete the mixing, granulating, coating and drying processes of powdery materials in the same equipment.
