Are you familiar with the structural composition and characteristics of laboratory fermenters?
Generally speaking, a laboratory fermenter, based on the form of the fermentation product, is a device that uses various liquid microbial raw materials to prepare a liquid culture medium at a fixed ratio, which is sterilized and then inoculated into a fermenter for fermentation. The above is mainly used for microbial fermentation. The fermenter is made of high-grade stainless steel, with accurate liquid culture medium concentration inside the liquid tank. The mixer inside the tank mixes the materials evenly, and the stirring paddle is used to disperse and break up foam. High dissolved oxygen rate, good mixing effect, promoting material fermentation reaction. It can achieve high-temperature sterilization and prevent material contamination. It complies with national GMP hygiene standards and is widely used in the food, pharmaceutical, and chemical industries.
A laboratory fermenter consists of three main systems: tank body, jacket, stirring system, jacket or coil, transmission device, shaft seal device, insulation, support, fermentation-specific sampling and discharge valve, cooling liquid inlet and outlet, temperature sensor interface, PH automatic control system, pressure sensor, air breather, CIP interface, etc.
The storage tank is generally made of SUS304/SUS316L high-grade stainless steel. The inner cylinder wall is mechanically polished or electropolished, and the outer cylinder wall is insulated by 304 welding. Appearance treatment: mirror polishing or matte polishing. The external connection of the cylinder is a hygienic quick-opening connector that meets national GMP hygiene standards, ensuring safety and hygiene without dead corners.
The laboratory fermenter online control system uses PLC automatic control with a color LCD touch screen to detect and control the relevant parameters of the fermentation process online. The control system includes sterilization interface, parameter setting and correction, data charts, data reports, fermentation batch number setting, online animation, alarm device, etc. It connects with the host, computer, printer, remote monitoring, and data. Storage and printing.
It is also equipped with temperature control devices, thermometer holes, CIP automatic rotating spray balls, antifoaming agents, baffles, air distributors, temperature sensors, sight glass spotlights, liquid level gauges, etc., which are convenient manual devices. Simple and reliable operation.
Structural characteristics of laboratory fermenters:
1. The tank body is made of high-quality stainless steel with polished inner and outer surfaces. Polishing accuracy Ra0.4, anti-sticking wall, easy to clean;
2. The stirring system adopts a three-layer six-flat-blade fermentation-specific standard paddle, and stepless speed regulation can realize fully automatic control of the fermentation stirring process; the structure is reasonable, easy to disassemble and assemble, with an automatic lifting device, convenient and safe to use;
3. The laboratory fermenter uses high-temperature steam sterilization, and the sterilization process is automatically controlled, with accurate sterilization temperature;
4. Swiss Mettler PH electrode and shielded wire, with a range of 2-12PH and a control accuracy of 0.02PH;
5. Antifoaming agent can be added to detect foam automatically, with a sensitivity of 100-10000; gas flow control can be manually adjusted according to the rotor flow meter, ranging from 0-5000 liters/minute; 6. The supply system can be automatically supplied by a perturbation pump, ranging from 0-5L/min, with a control accuracy of 2%.
