[0035] In use, the user connects the device to power supply, then adds liquid into the interior of the liquid storage tank body 1 through the liquid adding pipe 3. At this time, the fermentation medicine is put in, and then the driving motor 213 is started to drive the connecting rod 212 to make the stirring rod 211 rotate to stir and mix the liquid and the fermentation medicine. Then, the liquid level height inside the liquid storage tank body 1 is observed through the observation plate 221, and then the adjusting screw rod 225 is rotated to drive the second sampling box 228 to move up and down for adjustment. When the second sampling box 228 is adjusted to the appropriate position, stop rotating the adjusting screw rod 225 to fix the position of the second sampling box 228. Then, liquids at different heights will enter the interiors of the first sampling box 223 and the second sampling box 228. At this time, start the DC motor 231 to drive the movable disk 232 to make the blocking plate 233 rotate. Then, the blocking plate 233 will move to the right side of the second sampling box 228 and the first sampling box 223 to block them. Then, turn off the DC motor 231, hold the handle 226 and directly lift the mounting frame 2210 out of the side box 224 to take out the liquid for detection to check whether the appropriate fermentation degree is achieved.
