Description
Technical field
The present invention relates to technical field of tobacco processing, particularly a kind of fluid bed dryer.
Background technology
At present, domestic and international existing tobacco stem shred online expansion and dry boarding techniques extensively adopt fluidized bed drying setting method.
The fluid bed dryer of current use comprise frame, hot-air system and rack-mountedly all press bellows, fluidized drying room, shake groove etc., the top of fluidized drying room is provided with humidity discharging system.
Wherein, the groove that shakes is installed on frame by the truss that shakes, and the base plate of the groove that shakes is distributed with multiple mesh, the side plate bottom of the groove that shakes with all press bellows to seal, top and fluidized drying room seal.In specific operation process, hot-air system take steam as heat source air, and the air after heating is all pressed bellows by all pressing the air inlet of bellows to send into, pass into and all press the hot blast of bellows by all pressing the deflector of bellows to lead to shake the base plate of groove, and the material shaken in groove is brushed by the mesh on base plate, make material at the indoor fluidized drying of fluidized drying; The moisture that material produces is got rid of by humidity discharging system.
Because the mesh shaken in trough floor is perpendicular to horizontal bed surface, in specific works process, hot-air all in pressure bellows is by forming direct current thermal current from bottom to top after mesh, the material shaken in groove shake advanced by throwing in groove while be subject to direct current thermal current and brush formation fluidized state, now, material fully mixes with direct current thermal current, has larger convection current heating effect, thus dry setting rapidly.
But, due to the material supplied materials shaken in groove itself there is moisture inequality, granular size differs and weight such as to differ at the difference, it is in uneven thickness that the material shaken in groove is thrown forward and piled up on base plate in process; Wherein, the material of thinner thickness position easily seethes with excitement under the effect of direct current thermal current, and the material of the thicker position of thickness exists stem lamination, by direct current thermal current blow boil time material the height of boiling differ greatly.If direct current thermal current is too small, the material of the thicker position of thickness can not obtain effective dry setting; If direct current thermal current is excessive, it is higher from base plate distance when the material of thinner thickness position seethes with excitement, cause most of material because of the too high bed surface that can not fall back to trough floor of shaking that seethes with excitement, cause material can not normally send fluidized drying room, cause equipment to block together with follow-up material of coming in; Simultaneously, direct current thermal current is crossed conference and is damaged material particles, short grained material breaking end can block the mesh shaken on the filter screen of mesh in trough floor and humidity discharging system, and then cause the air quantity in fluidized drying room uneven, appearance material conglomeration and too drying or both phenomenons occur simultaneously, and make material moisture after drying uneven, material conglomeration causes Filling power to reduce, too drying causes resist processing ability to decline all can increase cost, and affects the stability of cigarette quality.
