The invention discloses processing equipment of liquid food. The processing equipment of liquid food comprises an equipment base, a top table, a side wall, a stirred vessel, a feeding hopper and a material guide pipe, wherein the top table in a horizontal attitude is arranged on the upper part of the base by virtue of support of the side wall; the outer wall of the stirred vessel is fixedly connected with the side wall by virtue of support of two transverse support columns; the feeding hopper is fixedly arranged on the top table; and a discharge end of the feeding hopper is connected with a feed end of the stirred vessel by virtue of the material guide pipe. The processing equipment of liquid food has a simple structure and ensures that in flowing colloidal liquid, a certain quantity of tiny bubbles are injected under a continuous sufficient and uniform stirring state; and an elastic air storage bag structure is adopted, and the inflated degree of the elastic air storage bag every timeis kept same all the time under the negative pressure effect every time.
