This invention belongs to the field of aquatic aeration technology, and specifically relates to an aeration and stirring device, comprising: a shell, a first aeration pipe, a stirring assembly, and a deceleration assembly; the first aeration pipe, the stirring assembly, and the deceleration assembly are disposed inside the shell, with the first aeration pipe located at the bottom of the shell, aerating the material inside the shell; the stirring assembly agitates the bubbles released by the first aeration pipe; the rotation of the stirring assembly drives the first aeration pipe to rotate; and the deceleration assembly makes the rotation speed of the stirring assembly greater than that of the first aeration pipe. By rotating the first aeration pipe, materials at greater depths can be fully aerated, while the rotation of the stirring assembly ensures that materials at less depths are fully aerated, resulting in uniform aeration of materials at different depths and improving aeration efficiency; the deceleration assembly makes the rotation speed of the first aeration pipe less than that of the stirring assembly, which facilitates the stirring assembly to fully agitate the bubbles released by the first aeration pipe into materials at less depths, improving oxygen utilization and increasing aeration efficiency.

The utility model belongs to the field of sauce processing provides a kind of sauce three-dimensional heating cooking equipment, including cooking jar, the side wall of cooking jar is fixedly connected with feed pipe, the lower surface of cooking jar is fixedly connected with discharge pipe, the circumferential surface of cooking jar is fixedly installed with several evenly distributed heating fins, the two side walls of cooking jar are fixedly installed with support frame, the upper surface of support frame is fixedly installed with fixed column;The utility model can be heated by the side wall to sauce material by the several evenly distributed heating fins set in the circumferential surface of jar body, so that the heating in jar body is more uniform, while the stirring effect of equipment is improved by the variable pitch helical blade set, cooperate the use of stirring fin, while the sauce material adhered to the inner side wall of jar body can be stirred in the stirring process by the gear ring and scraper etc. set, reduce the problem that sauce material adheres in jar body and causes it to appear scorched, also can clean the inside of jar body after cooking.
