[0002] In the fields of food and pharmaceuticals, there are some coating machines that coat pills, tablets, candies, etc. with organic films, water-soluble films, etc. The demand for tobacco popping beads is also gradually increasing. Currently, most tobacco popping beads are oil-soluble flavor popping beads, but the tobacco popping beads in the prior art are only coated with a colloid layer on the outside. The inventors found that due to the unique properties of the colloid, the dried popping beads will cause the coating layer on the outside of the popping beads to re-moisten or even dissolve due to the increase in environmental humidity, which makes it difficult to transport, store and export to high-humidity areas, seriously affecting the quality of the popping bead products and restricting the sales of oil-soluble flavor popping bead products.
