(2) dressing
Essence micropill is placed in to fluid bed bottom, with the coating solution making in step (1), carries out dressing: send 40 ~ 55 ℃ of hot blasts from bottom, micropill to be blown afloat, and regulate wind speed 1.5～2.5 m
3/ min, simultaneously from bottom spray coating solution, 0.05 ~ 0.1Mpa is pressed in spray, and spray velocity is 20 ~ 35 mL/min, makes coating solution be coated on micropill surface, and simultaneously by micropill through heated-air drying and shaping, after coating solution has sprayed completely, continue drum hot blast 5 ~ 15 min, micropill surface is dried up, the discharging that turns off the blast, obtains required flavouring essence for tobacco film coating pellet preparations.
As preferred version, in described step (2), essence micropill and film-coated mass ratio are 1:0.05～0.15.
The invention has the advantages that: by technique of the present invention, essence micropill is carried out after Cotton seeds to essence micropill and there is good intensity, moisture resistance, the performance such as wear-resisting, promoted dressing drying capacity simultaneously, overcome the intergranular adhesion problems of essence micropill, thereby the operating efficiency of short raising of dressing time art for coating, dressing yield rate is high.
