Fermenter Description:
Airlift fermenters (ALR) are the most widely used bioreactor equipment. This type of reactor has the advantages of simple structure, no bacteria contamination, high efficiency of dissolved oxygen, and low energy consumption.
(1) Widely used for large-scale production of single-cell proteins. However, it is not suitable for culture fluids with high viscosity or a large amount of solids. The equipment can be widely used in the aerobic fermentation process of antibiotics, amino acids, enzyme preparations, vitamins, organic acids, etc. It is used in the domestic production of glutamic acid, antibiotics, xanthan gum, glucoamylase, and citric acid. In terms of environmental protection, it can be used for sewage treatment
(2) The gas supply efficiency is high, and the ventilation in the air riser can be greater than the air intake of the bubble reactor, which is conducive to aerobic reactions
(3) Air flow stirring, specially designed built-in guide tube, special ventilation distribution mode, rotameter and mass flowmeter display, adjust the flow of gas according to the process requirements. Compared with the mechanical stirring fermenter, the energy consumption is lower, it can save 70%-80% of electricity and reduce the cost
German Siemens S7-200 series PLC control system + 10” LCD touch screen display operation, on-site direct operation (menu type), full English menu and interface; sampling and display of tank data, browsing and analysis of system data, and reading settings. Available Control the stirring speed, the temperature of the medium in the tank, Ph value, DO value.
