Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described, but not as limitation of the present invention:
A kind of foodstuff drying device, including including rack and the tower body being installed in frame, described tower body is the fabricated structure being layering, and grain-entering mouth 1 is arranged at tower body top, having grain outlet 7 bottom tower body, grain-entering mouth 1 is in turn below for dedusting section 2, delay section 3, drying section 4, cooling section 5 and row grain room 6.
Described dedusting section 2 is connected to cleaning shaft 8, and described cleaning shaft 8 is the bifurcation font pipeline having two entrance points, and other in which entrance point is located at delay section 3, and cleaning shaft 8 connection place of described dedusting section 2 is provided with filtration core 9.
Described delay section 3 is saved stack combinations by four and forms, each joint delay section 3 is mainly made up of galvanized pipe soldering member and door-plate, galvanized pipe seam is bolted on inside door-plate, play a supporting role, by being welded and fixed reinforcement on door-plate, when being not added with gate panel wall thickness, intensity and the rigidity of door-plate can be strengthened, to save material usage, alleviate weight, reduce cost.Four pieces of door-plates are fixed together by snap close.Delay section 3 is positioned at the front of drying section 4 in dry run, obstructed hot blast in delay section 3, Main Function is exactly slow down the stress formed in paddy kernel in dry run, promotes that paddy kernel internal moisture is displaced outwardly gradually, makes paddy kernel surface and internal moisture tend to balance.Tempering process advan is dry in next stage, reduces the percent cracked rice of Oryza glutinosa, it is ensured that the quality of Oryza glutinosa after baking.
Described drying section 4 is mainly made up of air intake angle box 41, air-out angle box 42, described air intake angle box 41 is positioned at below air-out angle box 42, below air intake angle box 41, surrounding is evenly arranged with pipeline of hot air furnace 14, described air intake angle box 41 and the angle box backplate in air-out angle box 42 intersect layout, are fully contacted thus obtaining with grain;
Described pipeline of hot air furnace 14 import department is provided with hot air flow gauge 13, and the preset value of hot air flow gauge 13 is 0.5m/s-0.7m/s.Suitably increase dry medium through the speed of grain layer, also can accelerate the dry run of grain.When hot blast humidity is identical with grain moisture content, hot blast flow velocity desiccation in below 0.5m/s scope is the most obvious, but when flow velocity increases to more than 0.7m/s, dry rate can not be made on the contrary to accelerate.
Described cooling section 5 passes into natural cold wind from bottom to top, adopts this streamed cooling procedure completing grain, it is not necessary to tempering processes.Cold medium moves up and the hot grain flowed downward has a sufficient heat exchanging process, not only ensure that certain precipitation rate, and grain grain all can be sufficiently cool from external-to-internal, thus ensure that out machine grain can directly put in storage keeping do not have get damp, the situation of local pyrexia, it is ensured that dry grain quality.
Being provided with vane type draining crop mechanism in described row's grain room 6, vane type draining crop mechanism end arranges threeway, and a port of described threeway is connected with the charging port of bucket elevator 10, and another port is that unloading port connects,
Described charging port and unloading port connection place are provided with the rotating port lid of push-and-pull, the rotating port lid of described push-and-pull is arranged in hydraulic axis, undertaken releasing by hydraulically powered mode, rotate, reversely rotate, indentation, thus the unlatching completing charging port and unloading port is changed.
It is provided with humidity measurement instrument in described row's grain room 6, after switch board accepts the signal of the grain drying situation of humidity measurement instrument feedback, can with the moisture comparison set, when reaching pre-set interval, it can send actuating signal, drives port lid action, close charging port, carry out row's grain;If be detected that moisture be not reaching to set interval, then port lid can by drive unloading port, make grain continue on through bucket elevator 10 and be transported to tower body cyclic drying again.
As optimization, described charging port and unloading port connection place are provided with the rotating port lid of push-and-pull, the rotating port lid of described push-and-pull is arranged in hydraulic axis, undertaken releasing by hydraulically powered mode, rotate, reversely rotate, indentation, thus driving the opening port lid combined with main shaft to realize the keying of opening, it is effectively reduced the space taken when port lid opens and closes.
The invention also discloses a kind of grain cold cycle stoving process, comprise the steps, wait to dry grain → bucket
Formula elevator → dedusting section → delay section → drying section → cooling section → unloading section, is put in storage by vane type draining crop mechanism if water content detection is up to standard, if water content detection is not up to standard sends into the grain-entering mouth circulation of tower body top by bucket elevator.
Cold cycle crop dryer of the present invention be experiments show that by rice drying, it is possible to meets the dry requirement of the corn such as Oryza glutinosa, and rice drying amount is 15t, Rice Kernel Moisture Content is dried to 13% from 24%, used time 12h, dry rate is 0.9%/h, and drying capacity is 13.75t%/h.Rice drying quality better after drying, does not affect germination percentage and Cooking Quality, has and widely popularize application value.
The content that this specification is not described in detail belongs to the known prior art of professional and technical personnel in the field.
