Abstract
Burlap-clad bales of turkish or other oriental small leaf tobacco are passed between two upright steam applicators each having a plurality of individual steam jet openings. The openings cause injection of steam through the outer burlap cover and penetration into the loosely packed bale along the grain of the bale. The outer burlap cover is then removed and the bale opened by placing the same on a vibrating conveyor.
Claims2
A method of premoistening and opening a burlap-wrapped bale of oriental tobacco, which comprises:
- conveying said bale horizontally in a rectilinear direction with the grain of the tobacco in the bale oriented generally transversely of the direction of movement of the bale,
- injecting a vertically-aligned plurality of steam jets directly into each side of the burlap-clap bale over the vertical height thereof as said bale is conveyed therepast to cause penetration of steam into the centre of the bale,
- removing the burlap covering from the resulting steam-treated bale, and
- vibrating the coverless steam-treated bale to cause the bale to fall apart and lose its integrity.
