Fermentation tank for scientific research and teaching

Abstract

The invention discloses a fermentation tank for research and teaching. The fermentation tank comprises a lower tank body and an upper tank body, wherein the lower tank body is made of a stainless steel material, the upper tank body is formed by a transparent glass cylinder, a seal ring is adopted for pressing and sealing between the lower end surface of the upper tank body and the upper end surface of the lower tank body, an upper pressing cover is arranged at the upper end of the upper tank body, a seal ring is adopted for pressing and sealing between the upper end surface of the upper tank body and the lower end surface of the upper pressing cover, and a pull rod is also connected between the top of the upper tank body and the top of the lower tank body. Due to adoption of the structure, the lower tank body is a stainless steel cylinder with a jacket and can be kept at a constant temperature with jacket water bath, students can clearly see the whole fermentation process through the upper half part during teaching, a stainless steel sterilization cover is additionally arranged on the upper tank body during sterilization, steam can enter the sterilization cover for sterilization, the inside and outside differential pressure does not exist in the glass cylinder of the fermentation tank due to adoption of the fermentation mode, the glass cylinder is free of stress, so that the explosion hazard caused by the stress of the glass cylinder is avoided, and the fermentation tank is reasonable in structure arrangement and is particularly suitable for teaching.

Description

technical field [0001] The invention relates to a fermenter, in particular to a fermenter for scientific research and teaching. Background technique [0002] There are various types of existing industrial fermenters, and different fermenters can achieve different purposes of fermentation. However, due to their strong economic value, the fermenters used in industry cannot observe the internal fermentation conditions from the outside. However, in teaching, it is necessary to observe the internal fermentation conditions from the outside, so it is difficult to use industrial fermenters in teaching. Even if someone uses industrial fermenters directly for teaching, these fermenters can only observe the results, not Observing the fermentation process does not enable students to obtain intuitive learning effects. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a fermenter for scientific research and teaching that can di...
