Embodiment

[0032] Example 2 A fermentation tank using ultrasonic defoaming, the structure can still refer to the attached figure 1 , But different from Example 1, the volume of the fermenter is 350m 3 , The volume of cyclone separator 3 is 30m 3 , The power of the stirring motor 2 is 420kW.

[0033] Three ultrasonic generators 4 are installed at the bottom of the fermenter cyclone 3. The defoaming reactor 7 and the transducer 5 are connected by a reducing rod and a flange. Five fixing nuts are arranged on the periphery of the flange. The connection method is screw connection. The transducer 5 is connected in series with a special high-frequency wire 6 and Connect to the controller 8 and the power supply.

[0034] Example 3 A fermentation tank using ultrasonic defoaming, the structure can still refer to the attached figure 1 , But different from Example 1, the volume of the fermentation tank is 500m 3 , The volume of cyclone separator 3 is 35m 3 , The power of the stirring motor 2 is 750kW. ...

Abstract

The invention provides a fermentation tank capable of defoaming by using ultrasonic waves. The fermentation tank comprises a fermentation tank shell and an ultrasonic wave generating device, and is provided with a stirring motor and a cyclone separator, wherein the cyclone separator is arranged at the upper part of the fermentation tank; the ultrasonic wave generating device is composed of a defoaming reactor, an ultrasonic wave transducer, a controller and a power supply; and the defoaming reactor is arranged at the bottom of the cyclone separator and is connected with the upper top of the fermentation tank shell. The fermentation tank provided by the invention is low in investment, simple and easy to install and easy to popularize, and can effectively eliminate fermentation foam, reduce the consumption of defoaming agent and improve the product quality. Thus, the fermentation tank has favorable popularization and application value in industries such as fermentation, chemical engineering and the like.

Description

technical field [0001] The invention belongs to the technical field of biological engineering machinery. Specifically, it relates to a fermenter that uses ultrasonic waves to eliminate foam in the fermenting industry. Background technique [0002] During the aerobic fermentation process, due to aeration, agitation and carbon dioxide produced by the microorganisms' own metabolism, the culture solution produces a lot of foam. A large amount of foam will bring more harm to production: 1. It will reduce the ventilation effect; 2. It may also cause a large amount of culture fluid to escape, causing waste and environmental pollution; 3. When the foam rises to the top of the filling, it will seep out from the shaft seal. pose a risk of contamination. [0003] The method of defoaming can be divided into mechanical defoaming and chemical defoaming. Mechanical defoaming is multi-purpose rake type, scraper type, disc type and so on. Chemical defoaming is the addition of defoaming a...
