Stainless steel fermentation tanks are generally made of fermentation tank materials and are suitable for various microbial fermentation projects. They are one of the commonly used microbial fermentation equipment in industry. The stainless steel fermentation tank body is made of SUS304/316L high-grade stainless steel and is welded by a cylinder and an oval or dish-shaped head. The inner and outer walls of the tank are polished, making it safe and hygienic with no dead ends. It can achieve high-temperature sterilization in place and complies with national standards. GMP hygienic standards, stainless steel fermentation tanks are widely used in dairy, bioengineering, pharmaceutical, fine chemical and other industries.

1. Structural composition of stainless steel fermentation tank

The stainless steel fermentation tank is mainly composed of three major systems: the tank, the jacket, and the stirring system. It is also equipped with a jacket or coil, a transmission device, a shaft seal device, an insulation medium, a support, a fermentation-specific sampling and discharging valve, and a cooling liquid inlet and outlet. , temperature sensor interface, PH automatic control system, pressure sensor, air respirator, CIP interface and other components.

Stainless steel fermentation tanks are generally made of SUS304/SUS316L high-grade stainless steel. The inner cylinder wall is mechanically polished or electrolytic mirror polished. The outer cylinder wall is insulated with a 304 fully welded structure. The outer surface is mirrored or matte treated; the external connection port of the cylinder is made of Hygienic quick-open joint, safe and hygienic, no dead ends, in line with national GMP health standards.

The stainless steel fermentation tank online control system adopts color LCD touch screen + PLC fully automatic control, which can detect and control relevant parameters of the fermentation process online. The stainless steel fermentation tank control system includes sterilization interface, parameter setting and correction, data curve chart, data report, fermentation batch number setting, online animation, alarm device, etc. It can be connected to the host computer, computer and printer to realize remote monitoring and Data storage and printing.

In addition, the stainless steel fermentation tank is equipped with temperature control device, temperature measuring hole, CIP automatic rotating spray ball, defoamer, baffle, air distributor, temperature sensor, sight glass spotlight, liquid level gauge and other equipment to facilitate manual operation. Simple and reliable.

2. Structural characteristics of stainless steel fermentation tanks

1. The stainless steel fermentation tank body is made of SUS304/SUS316L high-grade stainless steel, and the inner and outer surfaces are polished with a polishing accuracy of Ra0.4, which can prevent materials from sticking to the wall and is easy to clean;

2. The stainless steel fermentation tank mixing system adopts a three-layer six-flat blade fermentation-specific standard propeller with stepless speed regulation, which can realize fully automatic control of the fermentation mixing process;

3. The stainless steel fermentation tank adopts on-site high-temperature steam sterilization. The sterilization process can be automatically controlled and the sterilization temperature is accurate;

4. The stainless steel fermentation tank automatically detects foam and can add defoaming agent with a sensitivity of 100~10000; the air flow control can be manually adjusted using a rotameter, with a range of 0~5000L/min;

5. The stainless steel fermentation tank feeding system can automatically feed through a peristaltic pump, with a range of 0~5L/min and a control accuracy of ±2%.
