Embodiment 1

[0029] In this embodiment, a mechanical defoaming slurry includes a slurry body 1. The slurry body 1 is used to be installed on the stirring shaft of the fermentation equipment. When the stirring shaft rotates, it will drive the slurry body 1 to rotate. When rotating, the side that is first in contact with the foam is the liquid facing surface, and the surface opposite to the liquid facing surface is the back liquid surface. In this embodiment, several first mesh holes 100 are arranged on the above-mentioned liquid-facing surface, and several second mesh holes 101 are arranged on the above-mentioned liquid-back surface. The first mesh holes 100 and the second mesh holes The holes 101 pass through, and the size of the first mesh holes 100 is larger than the size of the holes of the second mesh 101 . With this structure, the foam is first in contact with the liquid-facing surface, and the cell wall of the first mesh hole 100 will cut the foam for the first time, and the foam tha...

Embodiment 2

[0038] This embodiment is an improved implementation of Embodiment 1. In this embodiment, it also includes a frame structure for strengthening the overall structural strength. connected together, thereby preventing the present invention from falling apart due to strong rotational torsion force during use.

[0039] As a specific implementation of this embodiment, the frame structure in this embodiment includes four steel pipes 14 . The upper and lower parts of the above-mentioned liquid-facing panel 11 and the liquid-backing panel 12 are provided with through holes, and the through holes on the top of several liquid-facing vertical plates 11 correspond to form the first through-hole group one by one. The through-holes of the through-holes form the second through-hole group in one-to-one correspondence, the through-holes on the top of several back liquid vertical plates 12 form the third through-hole group in one-to-one correspondence, and the through-holes in the bottom of seve...

Abstract

The invention relates to a mechanical defoaming slurry, which belongs to the technical field of biological fermentation engineering, and comprises a slurry body, a plurality of first mesh holes are arranged on the liquid-facing surface of the slurry body, and a plurality of first grid holes are arranged on the liquid-back surface of the slurry body. There are several second mesh holes, the first mesh holes communicate with the second mesh holes, and the size of the first mesh holes is larger than the size of the second mesh holes. With this structure, the foam is first in contact with the liquid-facing surface, and the hole wall of the first mesh hole will cut the foam for the first time, and the undamaged foam will pass through the first mesh hole and connect with the second mesh hole. The walls are in contact with each other and cut by the second mesh hole wall. In this way, through the multi-layer cut foam, the foam is instantly changed from large to small, and finally completely broken into liquid and thrown out, so that the mechanical disinfection provided by the present invention Foam slurry has a significant defoaming effect.

Description

technical field [0001] The invention belongs to the technical field of biological fermentation engineering, in particular to a mechanical defoaming slurry. Background technique [0002] In the deep liquid fermentation process of the biological fermentation industry, because the fermentation medium contains sugar, protein and fermentation metabolites and other stable foaming substances, and the fermentation process needs ventilation and stirring to solve the problem of mass transfer and oxygen transfer, so in the fermentation process A certain amount of foam will be produced. When the amount of foam is small, it will not affect the fermentation process, but if there is a lot of foam, it will seriously affect the fermentation process and product quality, especially for fermentation with large ventilation. There are a lot of foams during the growth period of the bacteria and the synthesis period of the product, and even the top falls, which may cause the escaping liquid to redu...
