detailed description

In view of the deficiencies in the prior art, the utility model of the present invention has been able to propose the technical solution of the present invention through long-term research and extensive practice. The technical solution, its implementation process and principle, etc. will be further explained below with reference to the accompanying drawings.

Referring to FIG. 1, a vacuum mixer according to this embodiment includes a material mixing unit 1 and a condensing recovery unit 2, and the material mixing unit 1 includes a stirring assembly 12 and a mixing chamber 11, and the mixing chamber 11 is provided with a feed. Feed port and discharge port, and An air outlet 13 is provided at the upper portion. The condensing recovery unit 2 includes a condensing pipe 22 that communicates with an air outlet 13 of the mixing chamber, and the condensing pipe 22 is also connected to a vacuuming device 3 that causes the mixing chamber to form a vacuum environment.
