Different materials can be quantitatively added into the tank body 1 through the gravity sensor 8, so that the iodine solution and the additive are mixed in proportion. Gravity sensors are known in the art.

In this embodiment, the can body 1 is cylindrical, closed at the top by a flat head 2 and closed at the bottom by an elliptical head 3. The bottom center part of the oval head is provided with a discharge hole 108. The discharge port 108 also functions as a drain. The flat plate end enclosure 2 is provided with a stirrer mounting port 107, a raw material inlet 105, a drain port 102, a liquid level sensor mounting port 101, a pure water inlet 109 and a manhole 100. The agitator mounting port 107 is located about one-half the radius of the circumference of the tank between the manhole 100 and the material inlet 105. The vertical agitator 6 of installing in agitator installing port 107, agitator 6 includes motor, reduction gear and (mixing) shaft, and the (mixing) shaft extends to the bottom of jar body 1. At least an upper propeller type stirring blade and a lower propeller type stirring blade are arranged on the stirring shaft.
