Generally speaking, the laboratory fermentation tank is based on the form of fermentation products. It refers to a device that makes various liquid bacteria raw materials into liquid culture medium according to a fixed proportion, and then connects them to the fermentation tank for fermentation after sterilization. The above is mainly used for microbial fermentation. The fermentation tank is made of high-grade stainless steel, and the liquid medium concentration in the liquid tank is accurate. The mixer in the tank mixes the materials evenly, and the stirring paddle is used to disperse and break foam. High dissolved oxygen rate, good mixing effect, and promote material fermentation reaction. It can realize high temperature sterilization and prevent material from being polluted. Comply with national GMP. Health standards are widely used in food, pharmaceutical, chemical and other industries.

The laboratory fermentation tank is composed of three main systems. Tank body, jacket, mixing system, jacket or coil, transmission device, shaft seal device, insulation, support, special sampling and discharge valve for fermentation, coolant inlet and outlet, temperature sensor interface, PH automatic control system, pressure sensor, air respirator, CIP interface and other components.

The tank is generally made of SUS304/SUS316L high-grade stainless steel. The inner cylinder wall is mechanically polished or electrolytic mirror polished, and the outer cylinder wall is insulated by 304 welding. Appearance treatment: mirror polishing or matte polishing. The connection outside the cylinder is a sanitary quick-opening joint that conforms to the national GMP sanitary standard, safe and sanitary without dead angle.

The laboratory fermentation tank online control system adopts PLC automatic control with 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 chart, data report, fermentation batch number setting, online animation, alarm device, etc. It is connected with host, computer, printer, remote monitoring and data. Storage and printing.

It is also equipped with convenient manual equipment such as temperature control device, thermometer hole, CIP automatic rotary spray ball, defoamer, baffle, air distributor, temperature sensor, mirror spotlight, liquid level gauge, etc. The operation is simple and reliable.

Structural characteristics of laboratory fermentation tank:

1. The tank body is made of high-quality stainless steel and its internal and external surfaces are polished. Polishing precision Ra0.4, anti-sticking wall, easy to clean;

2. The mixing system adopts the special standard paddle for three-layer six-blade fermentation, and the stepless speed regulation can realize the full automatic control of the fermentation mixing process; Reasonable structure, convenient disassembly and assembly, automatic lifting device, convenient and safe use;

3. The fermentation tank in the laboratory adopts high-temperature steam sterilization, the sterilization process is automatically controlled, and the sterilization temperature is accurate;

4. Swiss Mettler PH electrode and shielded wire, with a range of 2-12PH and a control accuracy of 0.02PH;

5. Defoamer can be added to detect automatic foam with sensitivity of 100-10000; The air flow control can be manually adjusted according to the rotameter, with the range of 0-5000 L/min; 6. The supply system can be automatically supplied by the disturbance pump, with a range of 0-5L/min and a control accuracy of 2%.
