Using the specific grain-drying method of the application dryer：Cereal is loaded into feed hopper 9 first, starts discharge motor
35 drive refuse rotors 34 make cereal fall into lower auger 37, and cereal is transported ahead to elevator 3 by lower auger 37, and elevator 3 is by paddy
The supreme auger 25 of thing vertical-lifting, the cereal that upper auger 25 transports fall into dust removal machine 30, are filtered by sieve 28, utilize dedusting
Dust that motor 27 falls cereal etc. is discharged, and opening blow-off valve 29 makes cereal insert in drying tower 4 until full material；Then start
Hot-air system, after the hot blast temperature of hot-blast stove 2 is reached 120-150 DEG C, hot-air channel 33 is introduced using air-introduced machine 18 by hot wind
It is interior, while open air exhauster 8 and be exhausted；Secondly by the air quantity of control air-introduced machine 18, the temperature in drying tower 4 is controlled to be
80-120 DEG C, and start stirring motor 42 and drive the spiral 32 pairs of cereal of agitation to dry, until grain moisture content is 13%-
15% obtains storage requirements；Finally open the herringbone bucket 16 on dump skip 11 and more side cars 17 carry out discharging, hindered when there is discharging
During the situation of plug, Vibration on Start-up motor oscillating promotes blanking, the cereal after drying drop down onto transport assembly 13 transport to bunker or
Person is elsewhere.Cereal after finding to dry does not meet drying requirement, cereal is transported again to feed hopper 9, carried out again
Drying, until reaching drying requirement.
The application dryer is suitable for the drying operation of cereal, and substantial amounts of rope, weeds, straw are such as mixed into wet paddy to be dried
The debris such as stalk, stone will influence the flowing of cereal, and the uniformity of drying, easily causes feed hopper, grain discharging wheel and lower auger portion
The blocking of part causes fire.Therefore it is required that the rate containing debris of cereal is required below 2%, most long below stalk 5cm.In addition need
Want periodic inspection and clean all parts, the spiral strand piece of upper and lower auger using to shaft end height 30mm as boundary, less than 30mm
It must replace in time.Dryer main body is metal structure, as the height of dryer exceeds surrounding buildings, then should install lightning rod.
Reach good drying effect, reduce percent cracked rice and percentage of damage, hot-blast stove intake air temperature should be set in relatively low level, and single dries
Dry duration suggestion is advisable when 18-26 is small, and user should regard the concrete condition of drying cereal, select suitable intake air temperature and drying
Duration, hot-blast stove intake air temperature is lower, and drying time period is longer, and drying effect is better, and percent cracked rice and percentage of damage are lower.
Since drying temperature drying tower bottom caused by the dryer of the application avoids simple bottom-heated mode
Step decay so that the non-uniform problem of grain-drying, three face three-dimensional heating modes of use, improve the drying of cereal
Uniformity, improves drying effect.The purpose of the filtering impurities and dust to cereal is realized using dust removal machine, is controlled using blow-off valve
System enters the cereal amount in drying tower, realizes the accurate control of cereal amount, is carried out using the spiral cereal in drying tower is stirred
Agitation, so as to realize stirring in drying course, further ensures the uniformity of drying, dump skip set multiple herringbone buckets and
More side cars are discharged easy to cereal, while the vibration skirtboard driven using vibrating motor, easy to blanking, avoid cereal from blocking.This Shen
Drying machine drying please is efficient, and the degree of automation is high, has a vast market prospect.
