In the process of mixing the instant tea powder with the solvent, a certain amount of tea powder is first added to the switching component 4 by using a pipeline, and further added to the stirring component 2 by the switching component 4, and then reaches the filter ball 3. Then, the switching component 4 is switched to be connected to the solvent, and the solvent is added to the stirring component 2, and the tea powder in the filter ball 3 is continuously flushed to accelerate the dissolution of the tea powder. After the tea powder is completely dissolved in the solvent in the preparation tank 1, the prepared instant tea is discharged, and then the switching component 4 is switched to add a certain amount of tea powder, and so on, so as to achieve efficient production of instant tea and ensure accurate proportioning.

[0030] In this embodiment, when the stirring component 2 is stirring, the stirring component 2 can be started to rotate through the switching component 4 to add the mixture between the instant tea powder and the solvent in the preparation tank 1. And in the process of adding the solvent through the upper inlet joint 23, when the liquid level of the preparation tank 1 reaches a preset height, the upper inlet valve 231 will be controlled to close, and the lower inlet valve 241 will be opened, so that the preparation liquid in the preparation tank 1 is sucked by the suction pump, and circulated through the stirring rod 25 and discharged from the filter ball 3, so that the solution is circulated to improve the dissolution efficiency.
