Automatic foam eliminating machine

Abstract

The present invention discloses one kind of automatic foam eliminating machine used in fermentation process, and features that the automatic foam eliminating machine includes one mechanical device and one automatic control system. The mechanical device includes five nozzles of different sizes, rear sucking pipe, outer edge, spraying cavity and flanges; and the automatic control system is installed inside the operation chamber. The present invention is designed based on fluid mechanic principles, and has raised production efficiency and environment friendship.

Description

technical field [0001] The invention relates to a defoaming device, in particular to an automatic foam swallowing machine used in the fermentation process. Background technique [0002] At present, in the production process of citric acid, glutamic acid, lysine, enzyme preparations, antibiotics and other biological aerobic fermentation fields, a large number of foams are inevitably generated, and these foams must be removed, otherwise the production will be seriously affected. However, in real life, people generally use the traditional defoaming method, that is, the combination of defoaming rake and defoaming agent. Its disadvantage is that the defoaming rake only installs a raking scraper on the top of the liquid surface in the tank to break the large bubbles on the surface into small bubbles, and the result is that the foam cannot be removed; but it has no choice but to use chemical agents (such as: defoamer) , vegetable oil) for defoaming, although the foam can be remove...

Problems solved by technology

Its disadvantage is that the defoaming rake only installs a raking scraper on the top of the liquid surface in the tank to break the large bubbles on the surface into small bubbles, and the result is that the foam cannot be removed; but it has no choice but to use chemical agents (such as: defoamer) , vegetable oil) for defoaming, although the foam can be removed, one is that the cost is too high, and the other is that it pollutes the environment

[0003] I invented the utility model foam swallowing machine in 1999. Its patent number is: ZL99247539.2. It has been tested in some manufacturers successively. Its defoaming method is powered by sterile compressed air. Although this invention saves a lot of defoaming agent, it takes a long time to swallow the foam due to the limitation of the amount of straw. At the same time, it is not equipped with an automatic control system, and manual operation is required, which brings a lot of trouble to production.
