The side wall of the tank body is provided with a circulating outlet 717, the circulating outlet is positioned at the upper part of a liquid space (the liquid space is below the liquid level of the tank body) in the tank body, the circulating outlet is connected with the tangential inlet through a circulating pipe 722, and the circulating pipe is provided with a circulating pump, so that liquid in the tank body can be pumped out through the circulating pump and then enters the tank body from the tangential inlet again, and the proper liquid rotational flow in the tank body is pushed or maintained.

The circulating outlet is also connected with a spraying system which is used as a water source port for spraying, a spraying pump is arranged on a connecting pipe between a spraying pipe 751 of the spraying system and the circulating outlet, a nozzle 756 is arranged on or connected with the spraying pipe of the spraying system and is positioned above the liquid level of the tank body, so that the sprayed liquid falls into the tank body, and the liquid in the tank body can be pumped out by the spraying pump and returns to the tank body in a spraying mode. In the spraying process, volatile substances such as DMS and the like in the liquid are effectively volatilized, so that the spraying time and the spraying amount can be controlled according to actual needs, the DMS and the like remained or generated in wort in the sedimentation tank are reduced, and the quality of the beer is improved.

The spraying system is also provided with a water supply pipe 53 for connecting an external water source, the water supply pipe is connected with the spraying pipe and is provided with a water supply pump so as to spray through the external water source in the washing process (in the working process of the mud scraper), spray water is mixed with the scraped sediments and flows into the mud collecting groove together, and the position of the nozzle can be properly set so that the spray water can cover the whole bottom surface of the pool bottom.

Due to the arrangement of the rotary mud scraper, the bottom surface of the pool body can not incline normally, but can incline to a certain extent, so that one side of the mud collecting groove is higher and the other side of the mud collecting groove is lower, and mud collection is facilitated. Namely, the axis of symmetry of the conical surface of the bottom surface of the tank body may be perpendicular to the horizontal plane or not, and an included angle is formed between the axis of symmetry and a vertical line perpendicular to the horizontal plane, the included angle is preferably 0 to 5 degrees (including an end value), and when the included angle is zero, the tank body is in a non-inclined state.

The sludge discharge port is positioned at the lowest end of the sludge collecting groove.

The feed liquor side of tangential import can be connected with surge-chamber 725, the surge-chamber is the space that the area of overflowing is obviously greater than relevant pipeline and tangential import area of overflowing, can be cylindrical or square column form etc. to realize the voltage-sharing of liquid from this to guarantee that the rivers that the tangential import flows out are stable and the direction is unanimous, form the whole whirl of cell body better and prevent because of the destruction of local disorder to albumen flocculation, the circulating pipe is connected the import of surge-chamber.

The pressure equalization chamber is provided with an ultrasonic device 728 (typically consisting of an ultrasonic generator and transducer in cooperation) having an ultrasonic output element (e.g., horn) located in or extending into the pressure equalization chamber to form ultrasonic waves in the liquid in the pressure equalization chamber to disrupt hydration or other stabilizing elements at the surface of the protein by mechanical impact, cavitation and thermal effects to facilitate re-flocculation and sedimentation and allow for thermal coagulation of the remaining partially thermally coagulated protein. The working time of the ultrasonic wave can be determined according to actual needs, for example, after a period of precipitation time, substances which are easy to precipitate basically precipitate, the ultrasonic wave equipment is started, and the form and flocculation and sedimentation performance of part of the heat coagulation protein which is difficult to precipitate are improved, so that better precipitation separation is realized.

The various pipes or openings for external connection or material input and output, etc. arranged on each device (e.g. a boiling pot, a vaporization separation device, a gas-liquid mixer, a sedimentation tank, etc.) can be in the shape of short pipes, related pipelines, or pipe openings (openings) for pipe connection or material input, e.g. connecting interface flanges, or openings for directly welding external pipelines, etc.

The preferred and optional technical means disclosed in the present invention can be combined arbitrarily to form a plurality of different technical solutions, except for the specific description and the further limitation that one preferred or optional technical means is another technical means.
