Abstract

DC60 (17/03/53) This invention relates to the continuous microalgae production container and the continuous microalgae production system. The invention is designed with a simple system for low cost and easy operation. to system operation But it is effective in producing algae cells without protozoan contamination. and other unicellular algae that are not required. continuous algae The container for continuous microalgae production is a closed container made of resistant material. hot and chemical and control the pressure inside the container to be higher than the outside air by spraying filtered air into the container all the time The algae culture medium prepared in the culture medium storage container is pumped and filtered by a kit. Filter pore sizes smaller than 1 micron before being introduced into the container. during microalgae production growing cells Suspended in the culture medium is continuously pushed out of the microalgae producing vessel by the pressure of the air. flow from the container to the microalgae storage container This invention can be used in the aquaculture industry. and other industries that uses algae as raw materials, such as the food and pharmaceutical industries chemical industry, etc. This invention involves containers for continuous microalgae production and continuous microalgae production systems. It is an invention that is designed to have a simple operation system for low cost and easy to operate. But it is effective in producing algae cells without protozoan contamination. and other unicellular algae unwanted This invention method can control the continuous addition of algae culture medium into the microalgae production vessel. The container for continuous microalgae production is a closed container made of heat and chemical resistant materials. and control the pressure inside the container to be higher than the outside air by constantly spraying filtered air into the container The algae culture medium prepared in the culture medium is pumped and filtered with a filter with holes smaller than 1 micron before being introduced into the container. during microalgae production The growing cells suspended in the culture medium are continuously ejected from the microalgae production container by the force of air flowing from the container into the microalgae storage container. This invention can be well applied in the aquaculture industry. and other industries that uses algae as raw materials, such as the food and pharmaceutical industries chemical industry, etc.
