Title: Structure and application of industrial fermentation tank handle.

As an important part of biotechnology, industrial fermentation technology is widely used in medicine, food, chemical industry and other industries. Fermentation tank is one of the main equipment for microbial culture, and the handle, as one of the important parts of fermentation tank, plays a key role in opening and closing the tank.

I. Definition and classification of handles

The so-called handle refers to the handle installed on objects such as containers for people to switch or move by hand. According to different materials, it can be divided into metal handles, plastic handles and other types; According to the function, there are fixed handles (generally welded or riveted on the tank) and movable handles (which can open and close the tank cover by rotating).

Second, the design characteristics and requirements of industrial fermentation tank handle

1. Strong and durable structure: high temperature and high pressure conditions may occur during fermentation, so it is necessary to ensure that the handle has sufficient strength to withstand external impact without damage.

2. Good sealing performance: In order to prevent external impurities from entering and internal materials from leaking, it is necessary to ensure good sealing between the handle and the tank cover.

3. Simple and quick operation: the handle should be designed to be easy to hold and can easily complete the opening/closing action, which not only improves the work efficiency, but also reduces the physical fatigue caused by repeated work for a long time.

4. Convenient and hygienic cleaning: Considering the convenience requirement of cleaning the residues in the fermentor in the future, the surface treatment process of the handle should be as smooth as possible without dead ends to avoid bacterial growth and thus affect the product quality.

Third, the actual case analysis

For example, the stainless steel fermentation tank used in a factory is equipped with a circular top cover with a diameter of about 60cm and a set of movable handles to control its opening and closing state; This product adopts double-layer structure design to enhance the overall stability and give consideration to aesthetics; In addition, O-shaped rubber rings are specially arranged to strengthen the waterproof effect between the connecting parts; Finally, after testing and verification, all the indicators meet the expected goals and there is no abnormal situation after long-term use, which successfully meets the actual needs of the production line.

IV. Conclusion

In a word, the handle of industrial fermentor plays an indispensable role, which is directly related to the smooth progress of the whole production process. Therefore, designers must fully consider all factors before they can work out the most rational scheme, and strictly control each production process in order to achieve the best quality standards.
