The present invention relates to large-scale bioreactors having at least two impellers, large-scale bioreactor systems and methods for the large scale cultivation and propagation of mammalian cells using these bioreactors.

A bioreactor (30) for production and harvesting of microalgae is described, comprising a reactor basin (32) in the form of a tank arranged to receive CO2 and water as well as algae, and which is equipped with at least one outlet for harvesting of algal biomass, where the reactor basin (32) comprises a rotating beam (54) equipped with one or more tillable mixing grates (60) and harvesting grates (62).

The present invention relates to large-scale bioreactors having at least two impellers, large-scale bioreactor systems and methods for the large scale cultivation and propagation of mammalian cells using these bioreactors.

The present invention is a composting bioreactor system that can be continually fed with biodegradable solid wastes, waste waters and exhaust gases, that can automatically recycle the biodegradable wastes into liquid nutrients and heat energy, and that automatically supplies the nutritious liquid and heat into the integrated hydroponics system or aquaponics system. The invention together with the integrated food growing system can be installed onsite in places such as household balconies, household backyards and premises of restaurants and food factories etc. therefore can lead to zero mileage targets both for recycling the wastes and for growing the foods consumed in the same location. It can fully recover and reuse all the nutrients and heat energy from the treated wastes. It can also reach the target of nearly zero pollution to the environment during all processes. For better operational efficiency, an oblique cone agitator, a fish plow agitator and a vortex flower turbine are specially designed for the bioreactor system.

Embodiments of the present disclosure relate to a food waste disposer, and more specifically, to a food waste disposer which prevents the formation of a blind spot where food accumulates through the shape of a chamber in which food and microorganisms are accommodated, and improves the efficiency of food decomposition and processing by effectively stirring the food and microorganisms using blades and stirring rods.

A configurable system for repeatably performing processes related to tissue growth in a controlled environment, possibly part of an industrial production line. The system can accommodate various sizes and shapes of culture vessels, and can maintain the cells at a desired temperature in the culture vessels, thus enabling a plug and play system that can produce consistent and repeatable results. The system includes gas management, fluid management, and control of multiple processes simultaneously, and can be automatically operably coupled with a variety of supporting technologies that can enable tissue-related processes. The system can communicate with supporting technologies upstream and downstream on a manufacturing line, enabling fully automated process control, centralized data historization, and centralized control.

The application describes bioreactors comprising gas permeable membranes disposed on the housing covering at least partially a transfer opening. The bioreactor is also provided with a mixing element and ports adapted to receive sensors measuring values of parameters related to the process implemented in the bioreactor. The bioreactor comprises at least one opening in one of the walls. The at least one opening is covered with a gas permeable membrane.
