The novel atomized drying complete apparatus is in use, first, by the air-cooler 6 of 1 conical shell of drying tower, 9 lower part,
Flow velocity is passed through in 10~14m/s via cold air inlet 16, into the inside cold wind interlayer 13 of 1 tower body of drying tower（Such as：
11.83m/s）Cooling wind；Cooling wind passes through 9 inside cold wind interlayer of conical shell, 13 lower part, by several ventilation 29 structures of riser
Into independent air intake space, be equably conveyed into inside cold wind interlayer 13；Meanwhile cooling wind is via loop vent partition board II 15
Ventilation hole 28 on loop vent partition board I 14, is delivered up layer by layer, and then effectively promotes the heat transfer effect of tower body inner wall 35
Fruit achievees the purpose that reduce by 35 temperature of tower body inner wall, prevents the fouling in tower body inner wall 35 of high temperature drying particle from accumulating.Then,
Start the air pump of tower wall sweeper, wind is cleaned from the conveying into storage wind axis set 32 of wind entrance 19 is cleaned；Wind is cleaned by being swept into
Air port 34 enters lower part and cleans in pipe 23 and upper part cleaning pipe 25, and is discharged via air holes 40 is cleaned.And then open tower wall
The cleaning driving motor 18 of sweeper drives rotational stem 20 to rotate, and then drive and be arranged in tower body inner wall by retarder 17
Lower part on 35 cleans pipe 23 and upper part cleaning pipe 25 rotates together.
Then, the atomized liquid entrance 10 set by 3 middle part of top hot-air distributor, injects into 1 tower body of drying tower
Fruits and vegetables liquid after being atomized via atomizer 2；What the liquid after atomization was continually fed into using burner 4 into hot-air distributor 3
Hot wind, to carry out high temperature drying；Meanwhile start the feeding driving motor 49 of dry powder feeder 7, drive 41 inside bottom of charging chamber
The screw feeding axis 46 of setting rotates, and then by the SiO 2 powder of 41 bottom of charging chamber, is conveyed into via feeding tube 44 dry
In powder lower hopper 45.SiO 2 powder in dry powder lower hopper 45 enters again by feeding pipeline from atomized liquid entrance 10
Into drying tower 1, and then avoid the caking of powder material.Dry powder feeder 7 renovates 56 using discharging, to control auxiliary material addition
Speed avoids conveyance conduit from blocking.And with the rotation of screw feeding axis 46, the drive sprocket of 46 end set of screw feeding axis
47 are rotated by driving chain, drive driven sprocket 52, so as to drive the stirring shaft 42 of 46 top setting of screw feeding axis, connect
It is rotated together with the mixing component 43 arranged thereon, to carry out circulation stirring to the SiO 2 powder in charging chamber 41, effectively
It prevents from auxiliary material from putting up a bridge to lump, and conducive to the smooth conveying of SiO 2 powder.
During drying tower 1 works, the lower part that the tower wall sweeper in tower body persistently rotates cleans pipe 23 and top is clear
Pipe 25 is swept, using the cleaning wind for cleaning the discharge of air holes 40, cyclically tower body inner wall 35 is purged, to further prevent high temperature
Dry particle fouling on drying equipment inner wall is accumulated, it is ensured that product quality.Later, the fruits and vegetables dry powder object by spray drying
Material, dry particle floss hole 21 from 1 bottom of drying tower are transported to the dry of 5 cyclone separator of dehumidifying air conveying device, 61 top
At powder feed inlet 63；It is entered inside Whirlwind barrel 62 via dry-coal feeding mouth 63 again, and then using in cyclone separator 61
Helical blade 64 detaches vapor with dried dry material.Then, dry material by with 61 bottom of cyclone separator
Connected dry-coal feeding cylinder 71 is entered in air shuttle valve 68, and dry material is effectively collected by centrifugal sedimentation principle, and
The dehumidifying wind in 68 valve chamber 70 of air shuttle valve is conveyed into using dehumidifier 65, dry material is further dehydrated；Also, via dry
Powder feed inlet 63 is drained into 230 DEG C of air inlet in cyclone separator 61, in 68 row of air shuttle valve by being connected with dehumidifier 65
Leaving air temp when going out can be cooled to 90 DEG C hereinafter, so as to while the smooth feeding of realization dry material, can carry out in time
Subsequent room temperature packaging, avoids recontamination, it is ensured that product quality.The production efficiency of the novel atomized drying complete apparatus is high, labor
Fatigue resistance is low, operates steadily reliable.
