Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
Provided by Fig. 1, the utility model comprises frame and is installed on the tower body 1 in frame, grain-entering mouth 2 is arranged at tower body 1 top, grain outlet 3 is had bottom tower body, grain-entering mouth 2 is followed successively by grain storage section 4 below, high temperature following current drying section 5, first delay section 6, middle docility stream drying section 7, second delay section 8, low temperature adverse current drying section 9, 3rd delay section 10, counterflow cooling section 11 and row grain room 12, row has vane type draining crop mechanism in grain room 12, level-sensing device 13 is provided with in grain storage section 4, level-sensing device 13 is connected with digital control display instrument 14, digital control display instrument 14 is connected with the arrangements for speed regulation of vane type draining crop mechanism.
Described vane type draining crop mechanism comprises the grain-guiding plate 15 of the row's of being placed in grain indoor, and the lower end of grain-guiding plate 15 is provided with impeller 16, and impeller drives through motor, and motor controls through arrangements for speed regulation.
Described adverse current cold wind section can pass into nature cold wind.
The utility model adopts higher hot blast temperature that grain is rapidly heated in high temperature concurrent drying section 5, and takes away a part of surface moisture; Middle docile fluidized drying section 7 adopts moderate fever air temperature to slough large quantity of moisture; After above dryer section, grain kernel temperature raises, and sloughs so low temperature counter-current drying section 9 adopts lower temperature to reach the object avoiding again grain temperature to rise so high at the moisture that grain intragranular portion absorption affinity is stronger; Eventually pass the abundant cooling of counterflow cooling section 11, reach going out machine grain and directly can putting storage in storage of safe moisture and temperature, hot blast temperature is wherein between 120-160 degree Celsius, desirable 160 degrees Celsius of such as high temperature drying section, desirable 140 degrees Celsius of middle temperature is dried section, desirable 120 degrees Celsius of low temperature drying section.
The following current section of the utility model in concurrent-countercurrent foodstuff drying device, hot blast is identical with the flow direction of cereal, and first the hottest air contacts with the wettest grain, therefore can use higher hot blast temperature.Hot blast and cereal move in the same way, and cereal relies on gravity to flow downward.Depth of grain layer is generally 0.6-0.9m.Because grain is once thicker, gas-flow resistance is large, and static pressure is generally 1.8-3.8kpa.Most commercialization concurrent-countercurrent dryer is provided with multiple concurrent drying section, and is provided with delay section between two dryer section.The process of concurrent drying is, it is first low with temperature that high-temperature hot-air enters dryer, the grain contact that moisture is large, and once flows downward with grain.Because heating cereal temperature reduces rapidly when hot blast flows in the country, the moisture that the grain moisture increase heated up in beginning transpiring moisture, air is more conducive in grain seed outwards shifts.When waste gas leaves grain, the temperature of grain is not high.It should be noted that grain and hot-air of short duration contact after, at once enter delay section, departed from the environment of force drying, continue by self with not high heat carry out the wet conduction of seed inside.Reach grain to pile inner Grain water and balance mutually simultaneously, for lower step creates conditions in drying, avoid without tempering process, direct continuous drying, grain external skins shriveling, capillary blocking will cause energy consumption to increase, the possibility of skin breakage rate increase.Multi-stage concurrent flow drying adds the large feature that tempering is concurrent-countercurrent drying machine: concurrent-countercurrent dryer generally has 3 to 6 such processes to complete whole grain drying, and each Precipitation amount is 2%-3%.
After terminating concurrent drying, grain enters counter-current drying section.The process of counter-current drying is, high temperature air enters grain layer from bottom, on against grain stream, so first the grain grain flowed down from above contact is the air of relative humidity low temperature, along with moving down of grain, seed raises slowly with the temperature rising of air, and air humidity reduces gradually, the moisture then rapid evaporation of epidermis.The grain quality that this incremental drying mode has evaporated most of moisture to protection has Yi Chu very much.
Cooling section also adopts this inverse airflow pattern to complete the cooling procedure of grain, does not need tempering process.Cold medium moves up and has a sufficient heat exchanging process with the hot grain flowed downward.Not only ensure that certain precipitation rate, and grain grain all fully can cool from external-to-internal.This ensure that out machine grain can directly put in storage keeping there will not be get damp, the situation of local pyrexia, ensure that and dry grain quality.
Cooled grain is discharged by draining crop mechanism, and draining crop mechanism is made up of many row's grain six impellers, and output can regulate according to six impeller rotations, and row's grain speed (output) can manual adjustments.
Grain storage section is established upper and lower level detector chain with row's grain arrangements for speed regulation.When grain reaches high charge level, digital control display instrument is reported to the police, and now can stop into grain; When grain reaches low material level, digital control display instrument controls automatically to stop row's grain, to prevent hot blast short circuit through arrangements for speed regulation.
Concurrent-countercurrent dryer derives two kinds of types by total air inlet mode: one is middle air inlet mode.The same with the capable dryer that flows over of straight plate grain post, centre is wet wind room, and hot blast is to both sides angular tube air feed.Another kind is both sides air inlet mode.Independent multiple hot air chamber is formed, hot blast by pipeline and special hot air chamber from angular tube two side direction dryer air intake.This dryer every section air intake also has two kinds of versions: joint structure of ventilating: upper end is one deck funnel type, and each bucket lower link one slips grain cylinder, forms larger space, hot-air is uniformly distributed, and can not upwards flows between cylinder.Hot-air enters grain layer downwards, flows down to angular tube with grain simultaneously, gets rid of from angular tube, and grain enters delay section after exhaust angular tube.Air inlet all adopts angular tube structure with exhaust: the arrangement of levels angular tube can be parallel, also can be mutually vertical.Delay section grain layer must be greater than the depth of grain layer of drying section, controls air-flow direction by resistance of grain layer.
The utility model structure is simple, cost is low, can the height of control grain storage section material level very, prevent the phenomenon of grain spilling and hot blast short circuit from occurring, adopt adverse current cooling to guarantee hot grain slow cooling, fully cool, prevented half-cooked grain, and can effectively reduce the wastage, adopt concurrent-countercurrent mode to make grain heat-drying effective.
