Abstract

DC60 (17/03/53) This invention relates to a continuous microalgae production vessel and system. It is designed with a simple, low-cost, and easy-to-operate system while efficiently producing algae cells without contamination from protozoa and other unwanted single-celled algae. The method allows for continuous control of the infusion of algal culture medium into the closed, heat- and chemical-resistant vessel. The internal pressure is maintained higher than the external air pressure by continuously pumping filtered air into the vessel. The prepared algal culture medium in storage containers is pumped and filtered using a pore-sized filter (less than 1 micron) before being introduced into the vessel. During microalgae production, the growing cells suspended in the culture medium are continuously expelled from the production vessel by the air pressure flowing from the vessel into the finished microalgae collection container. This invention can be used in aquaculture and other industries that use algae as a raw material, such as the food, pharmaceutical, and chemical industries.

During algae production, the growing cells suspended in the culture medium are continuously pushed out of the production container by the air pressure flowing from the container to the collection container. This invention has promising applications in aquaculture and other industries that use algae as a raw material, such as the food, pharmaceutical, and chemical industries.
