Smooth coating device for thick-slurry-method reconstituted tobacco slurry and quality characterization method thereof

The invention discloses a thick-slurry-method reconstituted tobacco slurry leveling and film coating device and a quality characterization method thereof.The thick-slurry-method reconstituted tobacco slurry leveling and film coating device comprises a leveling plate and a driving mechanism, a film coating mechanism is arranged on the leveling plate, and a traction mechanism is arranged between the driving mechanism and the film coating mechanism; the driving mechanism drives the traction mechanism to move, so that the traction mechanism drives the film coating mechanism to move along the leveling plate, slurry is flatly spread on the leveling plate, and the device enables the slurry in the charging groove to be spread on the leveling plate at a constant speed, so that the requirement that a laser scanner scans the contour of the surface of a coating film is met. According to the method, contour scanning is conducted on the surface of a thick paste method slurry coating film through the laser scanning technolo
