The invention discloses a sea tangle airing sunlight room and a construction method and a purpose thereof. The sea tangle airing sunlight room comprises a plane foundation, a wall body, a preheating bin, a roof building, a venting window, an airing device and can be constructed into a movable room or an immovable room, an inclined plane type sunlight room and a scale type managed sunlight room. The various sunlight rooms are all used for airing sea tangles into dried products. The sea tangle airing sunlight room improves 30% of deep processing additional value of sea tangle cultivating enterprises and 3 times of airing efficiency, saves 70% of airing area and 50% of labor power, and reduces labor intensity.

The invention relates to a method for drying a fibrous web (F) in a drying device (1) and to a corresponding drying device (1), in which method the fibrous web (F) is guided in an open draw with multiple deflection through the drying device (1) through a plurality of intermediate drying spaces (3.1 - 3.n) which are arranged parallel to one another and describe web-guiding path sections, and is loaded on both sides with a drying medium, in particular hot air, for thermal transfer. The invention is characterized in that the fibrous web (F) is guided through the drying device (1) alternately in the vertical direction in and counter to the direction of gravity and vice versa.

The invention relates to a belt type fluidized drying machine which belongs to the field of forage machinery. The belt type fluidized drying machine comprises a shell, a hot air conveying device, a dust-collecting device and a draught fan, wherein a netted belt conveying unit is horizontally arranged in the shell; the netted belt conveying unit comprises an upper-layer netted belt and a lower-layer netted belt; a plurality of material-picking plates are uniformly, equidistantly and fixedly arranged on the surfaces of the upper-layer netted belt and the lower-layer netted belt along the length direction; a porous material plate which is used for receiving dropping materials transmitted by the upper-layer netted belt is arranged under the lower-layer netted belt in a parallel form; the porous material plate is fixed with the shell; the materials on the porous material plate are divided into a plurality of independent material drying units by the material-picking plates; the materials in each of the material drying units are under boiling fluidized drying state by adjusting the volume of hot air which upward passes through the porous material plate; and the materials in each of the material drying units are forward conveyed following the propelling of the material-picking plates during the drying process. The fluidized drying state of the material layer is realized by using the belt type fluidized drying machine; the drying efficiency and the drying uniformity are increased; and the materials are loaded by both of the upper and lower netted layers, so that the use ratio of space is increased.
