する。[Detailed Description of the Invention] The present invention relates to a double-tube spray dryer, and more specifically, a drying tube having a jacket tube around the drying tube, a stock solution supply nozzle provided at one end of the drying tube, and the stock solution supply nozzle. This invention relates to a double-pipe spray dryer consisting of a steam spray pipe that opens in the same direction from the inside at the tip of the double-pipe spray dryer.
従来、二重管乾燥機においては原液の予熱器又
は顕熱供給域を必要とし、そのため装置が大型に
なるとか、二重管々内流速が加熱のために遅くな
り管内面に乾燥粉が付着し熱伝導が悪くなるとか
の問題点があつた。 Conventionally, double-tube dryers require a preheater or sensible heat supply area for the raw solution, which increases the size of the device and slows down the flow rate within the double-tubes due to heating, resulting in dry powder adhering to the inner surface of the tubes. However, there were problems such as poor heat conduction.
本考案はこれらの問題点を解決したもので、噴
霧蒸気により原液の加熱と流速の上昇とを同時に

し、かつジヤケツト管からの熱伝導を良くするよ
うに構成したものである。 The present invention solves these problems by simultaneously heating the stock solution and increasing the flow rate using spray steam, thereby preventing powder from adhering to the inner surfaces of the drying tubes, and preventing heat from the jacket tubes. It is constructed to improve conduction.

後出口１１を経て適宜放出される。 The present invention will be explained below based on the illustrated embodiments. FIG. 1 is an explanatory diagram showing an embodiment of the present invention. A is a double tube spray dryer, in which a jacket tube 2 having a steam inlet 9 and a steam outlet 10 is provided around the drying tube 1, and a stock solution supply nozzle 3 is installed at one end of the drying tube 1. The nozzle tip 5 is provided with an opening in the axial direction. Further, inside the stock solution supply nozzle 3, there is provided a steam spray pipe (or steam supply nozzle) 4 whose tip opens in the same direction and coaxially with the nozzle tip 5 from inside. With this structure, the stock solution enters the stock solution supply nozzle 3 from the introduction tube 7 and is discharged or jetted into the drying tube 1 from the nozzle tip 5.
On the other hand, water vapor enters the steam spraying tube 4 from the introduction tube 8 and is sprayed from the tube tip 6, where it is mixed into the stock solution. Then, the stock solution is heated and the flow rate of the stock solution is increased.
While passing through the drying tube 1, the stock solution is transferred to the jacket tube 2.
The powder (solid content) is dried by the heat from the outlet 11 and taken out from the outlet 11. Note that the water vapor is appropriately released through the outlet 11 after heating the stock solution.

れる。 The drying pipe may be a long pipe, so the drying pipe can be used as a transport pipe for the stock solution, and even if a stock solution supply nozzle is provided at the bottom of the stock solution tank, the flow rate can be given to the stock solution by steam spraying. This eliminates the need for a stock solution pump to the drying tube, and the equipment is extremely simplified.
