Further, described wind pushing mechanism and heating arrangements are arranged on outside casing.
Further, described heater is that medium-wave infrared adds heat pipe.
Further, the multiple strip through holes on described air distribution plate are arranged parallel to each other.
Further, described multiple strip through holes are perpendicular to corn conveying direction and arrange.
Further, the vertical interval between adjacent two of described multiple strip through holes is equal.
For realizing above-mentioned second purpose, the present invention adopts the technical scheme that:
A kind of grain drying, it includes the controlled hot blast of above-mentioned any one and arranges device, and the top of described air distribution plate is located at by the guipure of grain transportation, and guipure passes from closed box.
The invention has the advantages that:
1, adopting S type air channel to make air-flow from bottom to top by air outlet, reduce windage, gas flow can be allocated by the dish valve that air outlet is arranged below, and the air-flow controlling tubaeform air outlet is uniform;
2, the air outlet in S type air channel is tubaeform at the cross sectional shape being perpendicular on corn conveying direction, adds blowing area, decreases it and takies volume, and air outlet is up-narrow and down-wide in the cross section being parallel on corn conveying direction, adds the blast of air outlet;
3, the multiple strip through holes offered on air distribution plate, hot-air is by forming body of wall shape air-flow after strip through hole, producing beating of uniformly continuous when corn can be made to flow on guipure, corn adds the time of contact with hot-air and contact area in suspended state, and drying effect is good;
4, the controlled hot blast of the present invention arranges that device structure easily realizes, good for grain drying feasibility, and uniformly, fully, drying efficiency is high for corn drying.
