Problems solved by technology

[0007] U.S. Patent No. 6673599 discloses a disc-shaped defoamer for fermenters, but the defoaming efficiency is reduced due to the small effective defoaming area, when the height of the foam of the liquid medium is higher than the height of the defoamer , the defoaming ability is significantly reduced, and the weight of the defoamer is large and the structure of the defoamer is very complicated, making this defoamer unsuitable for large fermenters due to the risk of contamination and damage

Embodiment Construction

[0037] 1. Defoamer for fermenter

[0038] A defoamer 1000 for a fermenter according to an embodiment of the present invention will be described in more detail with reference to the accompanying drawings.

[0039] refer to Figure 2 to Figure 5 , the defoamer 1000 for a fermenter according to an embodiment of the present invention includes a main body 100, a support portion 200, a plurality of first blades 310, 320, 330, 340, 350, 360, 370, and 380, and a plurality of second blades. Two blades 410 , 420 , 430 and 440 .

[0040] The main body 100 is disc-shaped, and the first hollow part 110 is formed at the central part of the main body 100 . The first hollow portion 110 is a portion where a rotating shaft of a defoamer 1000 for a fermenter is installed to a fermenter 2000 (to be described later).

[0041] The support portion 200 is a portion extending from the upper surface 120 and the lower surface 130 of the main body 100 . A second hollow part 210 connected to the first...

Abstract

Provided is a foam breaker for a fermentation tank. The foam breaker for a fermentation tank, according to an embodiment of the present application, may comprise: a disk-shaped body (100) having a first hollow part (110) at the center portion thereof; a support (200), which has a second hollow part (210) communicating with the first hollow part (110), and which is formed so as to extend from the upper surface (120) and the lower surface (130) of the body (100); and a plurality of first vanes (310, 320, 330, 340, 350, 360, 370, 380) installed on the lower surface (130) of the body (100).

Description

technical field [0001] The invention relates to a defoamer for a fermenter and a fermenter using the defoamer, in particular to a defoamer and a fermenter capable of effectively eliminating foam generated in the fermenter. Background technique [0002] When a fermentation object is obtained using a biochemical reaction and a fermentation process of microorganisms, foam is formed in a fermentation medium due to introduced oxygen, carbon dioxide produced by fermentation of microorganisms, and the like. [0003] When foam is excessively generated during fermentation, the fermentation process is adversely affected and the production rate decreases. [0004] In order to solve this problem, a foam reducer for suppressing foam generation can be introduced in the fermenter, but when the foam reducer is introduced too much, it will cause product quality problems. [0005] In order to solve the problem of excessive introduction of foam reducers, a method for eliminating foam by insta...
