Fermentation tank with ultrasonic wave generating devices

Abstract

The invention provides a fermentation tank with ultrasonic wave generating devices. The fermentation tank comprises a fermentation tank shell and ultrasonic wave generating devices I and II, and is provided with an air distributor and a cyclone separator, wherein the air distributor is arranged at the bottom of the fermentation tank and is connected with an air inlet pipe; the cyclone separator is arranged at the upper part of the fermentation tank shell; the ultrasonic wave generating device I is composed of a defoaming reactor, a transducer, a controller and a power supply, the defoaming reactor is arranged at the bottom of the cyclone separator and is connected with the upper top of the fermentation tank shell; and the ultrasonic wave generating device II comprises an annular steel pipe, a transducer, a controller and a power supply, the annular steel pipe is connected with the circumference of the air distributor and is communicated with the outside of the fermentation tank shell, the transducer is arranged inside the annular steel pipe, and the controller and the power supply are arranged outside 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.

Description

technical field [0001] The invention belongs to the technical field of biological engineering machinery. Specifically, it relates to a fermenter equipped with an ultrasonic generating device. 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. In the oxygen supply system, the air distributor of the fermenter is of great importance. The advanced degree of the air distributor is related to the power consumption of fermentation, air consumption, and dissolved oxygen in fermentation, which in turn aff...
