Abstract
The utility model discloses a corn drying device. The corn drying device comprises a housing and an air source, wherein a grain inlet is formed in the upper end of the housing, a grain discharge port is formed in the lower end of the housing, an air passage connected with the air source is arranged in the middle in the housing, the air source comprises a hot air source and a cold air source, the air passage is divided into an upper hot air passage connected with the hot air source and a lower cold air passage connected with the cold air source, an annulus between the hot air passage and the housing forms a corn drying layer, and the annulus between the cold air passage and the housing forms a corn cooling layer. According to the corn drying device disclosed by the utility model, dried grains are of good quality, market competitive advantages are obvious, and drying is uniform and has no difference from that of sun-dried grains; the drying cost is 50% that of the same industry; and the corn drying device further has the advantages of capability of taking preemptive opportunities, quick return, great price difference and capability of reducing to safe water content once.
Description
Technical field
The utility model relates to drying unit, specifically a kind of downflow type corn-drying device.
Background technology
Present grain particularly corn has significant proportion still to take the mode of Exposure to Sunlight in the rural area, trace it to its cause is exactly that cost is low, but efficient is extremely low, so industry for the industry cereal such as some grains, seed, feed, starch, grease, alcoholic and oil plant, must use special foodstuff drying device to carry out flash baking, but existing dryer insufficiency, drying efficiency is low, can not arbitrarily control output and precipitation range, temperature and the uniformity, even other same industries can only be dried by the fire twice, maybe dare not start, miss earning chance.
In view of this, for the problems referred to above, propose a kind of reasonable in design and effectively improve the corn-drying device of above-mentioned disappearance.
The utility model content
The purpose of this utility model is to provide the corn-drying device, oven dry grain quality better, and market is converted and is striven with the obvious advantagely, and uniform drying and Exposure to Sunlight grain are as good as; The oven dry cost is 50% of the same industry; Rob first chance, return this soon, price differential is large, and the machine can once be down to safe moisture content.
In order to reach above-mentioned purpose, the utility model provides following technical scheme: the corn-drying device, comprise shell, wind regime, described shell upper end is grain-entering mouth, the lower end is row's grain mouth, the air channel that is connected with wind regime is set in the middle of section in the enclosure, described wind regime comprises hot air source and cold wind source, the hot-flow flue that the air channel is divided into the connection hot air source on top is connected the cold air duct in connection cold wind source with the bottom, annular space between described hot-flow flue and shell forms the baking zone of corn, and the annular space between described cold air duct and shell forms the corn cooling layer.
Be provided with one deck tempering layer at least between described baking zone and cooling layer; Described tempering layer is overrided to form mutually by horn-shaped air inlet wind box and air draft horn shape wind box.
Form air intake and the air draft of downflow type between the horn-shaped air inlet wind box of described tempering layer and air draft horn shape wind box and hot-flow flue.
Described baking zone and cooling layer all arrange three layers at least, and described baking zone and cooling layer are overrided to form mutually by horn-shaped air inlet wind box and air draft horn shape wind box.
Form air intake and the air draft of downflow type between the horn-shaped air inlet wind box of described baking zone and air draft horn shape wind box and hot-flow flue; Form air intake and the air draft of downflow type between the horn-shaped air inlet wind box of described cooling layer and air draft horn shape wind box and cold air duct.
Described baking zone and grain-entering mouth place also are provided with the grain storage layer, the row's of being provided with grain layer also between described cooling layer and row's grain mouth.
Compared to prior art, the utlity model has following beneficial effect:
The utility model is different according to the equipment drying capacity, is respectively equipped with level Four, Pyatyi or six grades of downflow type dryer section and some counterflow cooling sections, is provided with delay section between two dryer section.In the downflow type dryer, hot blast and grain stream are to identical, at first high warm air meets with wet, the coldest grain, thereby its drying property is different from crossing current and mixed flow dryer, and the evidence downflow type dryer of the U.S. is than traditional cross-flow type dryer energy-conservation 30%, evidence, during concurrent drying, with the hot blast of 150 ℃, pass into moisture content and be in 25% corn, after the 7.5cm stroke, wind-warm syndrome just drops to 81 ℃.Britain Bruce studies show that, the wheat of 21.8% moisture content passes to the hot-air of 177 ℃, and after 6 cm strokes, the temperature of hot-air just is reduced to 70 ℃.As seen, in downflow type baking water machine, wind-warm syndrome and the highest grain temperature have than big difference, and dry corn time difference value can reach 40--80 ℃, thereby rate of drying is fast, and grain quality is good.
Description of drawings
Fig. 1 is the structural representation of corn-drying device of the present utility model.
In figure: 1, grain-entering mouth; 2, grain storage layer; 3, baking zone; 4, horn-shaped air inlet wind box; 5, air draft horn shape wind box; 6, hot-flow flue; 7, tempering layer; 8, cold air duct; 9, row's grain layer; 10, row's grain mouth.
The specific embodiment
Relevant detailed description of the present utility model and technology contents coordinate description of drawings as follows, yet accompanying drawing only provides the use of reference with explanation, and the utility model is limited.
According to shown in Figure 1, the corn-drying device, comprise shell, wind regime, described shell upper end is grain-entering mouth 1, and the lower end is row's grain mouth 10, and the air channel that is connected with wind regime is set in the middle of section in the enclosure, described wind regime comprises hot air source and cold wind source, the hot-flow flue 6 that the air channel is divided into the connection hot air source on top is connected the cold air duct 8 in connection cold wind source with the bottom, the annular space between described hot-flow flue and shell forms the baking zone 3 of corn, and the annular space between described cold air duct and shell forms the corn cooling layer.Be provided with one deck tempering layer 7 at least between described baking zone and cooling layer; Described baking zone and cooling layer all arrange three layers at least, and described baking zone and cooling layer and tempering layer are overrided to form mutually by horn-shaped air inlet wind box 4 and air draft horn shape wind box 5.Form air intake and the air draft of downflow type between horn-shaped air inlet wind box and air draft horn shape wind box and hot-flow flue or cold air duct; Described baking zone and grain-entering mouth place also are provided with grain storage layer 2, the row's of being provided with grain layer 9 also between described cooling layer and row's grain mouth.
