Application Tests of Coating Material,GTG,in Tobacco Seed Pelleting

For further improving the quality of pelleted tobacco seed and developing new coating materials, GTG and conventional coating materials were tested with different blending proportions.The results showed that comparing with conventional coating materials, the seeds pelleted with GTG were superior in appearance and physical characters such as splitting degree and time, strength, and uniformity, etc.However, the seed pelleted with GTG of different proportions differed in appea-rance, and the seed pelleted with 50% GTG + 50% conventional coating and auxiliary materials showed better overall quality.
