Abstract

The invention provides an air distributor of a fermentation tank utilizing ultrasonic waves for defoaming. The air distributor is arranged inside the fermentation tank and connected with an air inlet pipe, and an ultrasonic generator is arranged at the periphery; the ultrasonic generator comprises an annular steel pipe, a transducer, a controller and a power supply, wherein the annular steel pipe is connected with the periphery of the air distributor, and the transducer is arranged inside the annular steel pipe. The air distributor provided by the invention is small in investment, easy and feasible to install, and easy to promote, and can improve the quality of fermented products, and reduce the production cost. Therefore, the air distributor has good promotion and application values in the industries such as fermentation and chemical engineering.

Description

technical field [0001] The invention belongs to the technical field of biological engineering machinery. Specifically, it relates to a fermenter air distributor utilizing ultrasonic defoaming. Background technique [0002] In the process of aerobic biological fermentation, the supply of oxygen is a key factor, which has a great influence on the growth of bacteria and the accumulation of metabolites. 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 affects the quality of fermentation indicators. [0003] With the continuous improvement of understanding, most of the fermentation enterprises currently use ring-type air distributors or jet-type spherical air distributors. However, how to better break the bubbles and control the uniformity of the bubbles has become a major b...
