撹拌槽２内には、この回転軸９に固着された大小２種の
リボン状の第１撹拌羽根10および第２撹拌羽根11が回転
可能に収納されている。これらの撹拌羽根10および11が
撹拌槽２内で回転することにより槽内の粉体を撹拌し、
粉体の冷却効率を高めるようになっている。Inside the stirring tank 2, two types of large and small ribbon-shaped first stirring blades 10 and second stirring blades 11 fixed to the rotating shaft 9 are rotatably housed. By rotating these stirring blades 10 and 11 in the stirring tank 2, the powder in the tank is stirred,
It is designed to improve the cooling efficiency of powder.
なお、外側の第１撹拌羽根10と内側の第２撹拌羽根11

に行われ、よって冷却効率の低下を防止する。A constant gap is formed between the top of the first stirring blade 10 and the cooling surface 3, and powder is accumulated in this gap, and a layer of the compacted powder is attached to the cooling surface 3, Since the powder layer hinders heat exchange on the cooling surface 3, the cooling efficiency is reduced. However, by providing the scraper 12, this scraper 12
Moves near the cooling surface to scrape off the compacted powder layer, so that the heat exchange is smoothly performed on the cooling surface 3, thus preventing a decrease in cooling efficiency.
このスクレーパー12は、冷却面３との間隙距離が０即ち

In the former case, it is preferable that the cooling surface 3 be a smooth surface and that the rod-shaped scraper 12 be made of a resin (for example, MC nylon) having sufficient strength.
なお、スクレーパー12は、上述した棒状の構造のものに

８から排出される。When the powder temperature adjusting device 1 is used to cool powder such as wheat flour, the cooling liquid 15 is continuously supplied from the cooling liquid supply port 7 by the pump 27 or the like, and is circulated in the flow path 4. As a result, the cooling surface 3 of the stirring tank 2 is cooled and discharged from the cooling liquid discharge port 8.
一方、粉体投入口５より撹拌槽２内へ投入された粉体

輸送（例えばプラグ輸送）され、投入口５より撹拌槽２
内へ投入される。As shown in FIG. 3, the compressed air discharged from the air supply pump 19 is dehumidified (dried) through the dehumidifying device 20, and is supplied into the air supply pipe 21 in the direction of the arrow in the figure. A hopper 22 containing powder 23 for cooling is connected in the middle of the air supply pipe 21, and the powder 23 in the hopper 22 is supplied into the air supply pipe 21 via a valve 25. . The powder supplied into the air supply pipe 21 is transported (for example, plug transport) in the air supply pipe 21 by the air flow sent under pressure, and the stirring tank 2 is supplied from the charging port 5.
It is thrown in.

It is designed to be stored in.
このような空気輸送方式において、輸送空気を除湿装置
により除湿（乾燥）する理由は次の通りである。The reason for dehumidifying (drying) the transportation air by the dehumidification device in such an air transportation system is as follows.
撹拌槽２内を冷却する場合には、槽内の湿度が高いと冷

湿された空気を用いることにより、撹拌槽２内の湿度を
下げ、冷却面３の結露を防止し、上記弊害を防止する。When the inside of the stirring tank 2 is cooled, if the humidity in the tank is high, dew condensation occurs on the cooling surface 3, so that the powder near the cooling surface 3 contains water and forms a block. Therefore, by using dehumidified air as the transportation air, the humidity in the stirring tank 2 is lowered, the dew condensation on the cooling surface 3 is prevented, and the above-mentioned adverse effects are prevented.
