Each of these conventional apparatuses has a corresponding advantage, but on the other hand, the conventional apparatus of the stationary type has a problem that the time required for drying is long.
The conventional air-flow and agitation-type devices generate a lot of fine particles, and in some cases, may cause breakage or cutting of the powder.In addition, the spray-type conventional device includes its auxiliary equipment. There is a problem that the scale is too large. A conventional fluidized bed type apparatus has a mechanism (so-called vibrating conveyor type) that applies a linear vibration in one direction to advance the powder while jumping in a substantially vertical direction, even if the apparatus adds vibration. ), Similar to an apparatus that does not apply vibration, is suitable when the powder is a coarse powder having a relatively large particle size, but is suitable when the powder is a fine powder having a particle size of 30 μm or less. It is difficult to fluidize the fine powder stably,
Therefore, there is a problem that it is difficult to actually dry such fine powder.

た場合も同様の結果が得られた。Next, the present invention will be described in a specific use state of the embodiment shown in FIG. 1 and FIG. Into a closed horizontal container 11 with a diameter of 400 mm × length of 800 mm, an average particle size of 10 μm, a true specific gravity of 0.8 g / ml,
A synthetic resin powder having a dry bulk density of 0.2 g / ml and a moisture content of 10% was supplied from the raw material supply port 22 to a height of 150 mm. Gas dispersion material 41
Both a and 41b are porous metal plates having an average opening diameter of 5 μm. By operating the vibration motor 13, vibration is applied to the closed horizontal container 11 at a total amplitude of 0.5 mm × frequency of 100 Hz, and at the same time, steam at 80 ° C. is circulated through the jacket 31.
The heated dehumidified air was blown at a rate of 50 l / min through the gas dispersion material 41a and at a rate of 150 l / min through the gas dispersion material 41b. At the beginning of drying, the fine powder has a flat surface, and forms a fluidized bed with little bubbling or slugging. In the fluidized bed, a clear turning or rotating motion in the short direction is recognized, and Countless small bubbles were generated from the surface. The formation of such a fluidized bed becomes more stable as drying proceeds, and in the final stage of drying, the fluidized bed has a liquid-like appearance, and the bed height is about 1.
It was up to 5 times. After running for 30 minutes, the product recovered from the product outlet 23 has a moisture content of 0.01% or less,
Its properties were very good. Although not described, similar results were obtained when the fine powder was continuously dried using the embodiment shown in FIG.

成してなる微粉体の乾燥装置。A closed horizontal container equipped with one or several vibration sources and a main heating source is supported by an elastic body such as a spring so as to give a certain free movement. The container has a gas outlet above the raw material supply port and the height of the fluidized bed of the fine powder to be formed, and a product outlet inside the height of the fluidized bed, and a gas dispersion material is installed below the product outlet. And the gas dispersing material is divided into two or more parts, and a sub-heating source is provided below the gas dispersing material, and a different amount of gas is supplied to each of the divided gas dispersing materials. The passage is piped, and the vibration generation source and the main heating source function to vibrate and heat the closed horizontal vessel. On the other hand, the auxiliary heating source functions to close the closed horizontal vessel through the gas dispersion material through the gas dispersion material. Inject different amounts of heated gas into the container. Accordingly, the fine powder was supplied from the raw material supply port are fluidized and closed system turning to the rotated while configured fine powder of the drying apparatus comprising as drying under a heating atmosphere in the lateral direction of the horizontal container.
