Industry information

Biological fermentation engineering is a high-tech process. The entire fermentation process is as follows:

Seed Culture Preparation

First, high-quality microbial strains are selected for pre-cultivation, and an appropriate amount of seed culture is prepared for later use. This step ensures that there are enough active microorganisms for metabolic activities during the fermentation process.

Fermentation Tank Sterilization

The fermentation tank is thoroughly cleaned and sterilized to ensure there is no contamination during fermentation. This step is critical for maintaining a pure fermentation environment and preventing external microorganisms from interfering with the process.

Fermentation Tank Loading

After sterilization, an appropriate amount of selective culture medium is added to the fermentation tank, and the pH and temperature are adjusted to help the microbial population adapt to the fermentation environment. This step provides a suitable growth environment to promote the proliferation and growth of microorganisms.

Inoculation

The prepared seed culture is introduced into the fermentation tank, maintaining the optimal growth environment to promote the proliferation and growth of microorganisms. This step introduces the active microorganisms to start the fermentation process.

Fermentation Process Monitorin

The growth rate of the microbial culture and factors such as temperature, pH, and oxygen supply during fermentation are continuously monitored to maintain optimal conditions. This step ensures that the fermentation process occurs under the best conditions, improving fermentation efficiency and product quality.

Process Flow

Pain point background

In fermentation processes, compressed air comes into direct contact with the fermentation liquid, meaning the quality of compressed air directly impacts product quality.

Pain Point 1

Traditional compressors are difficult to achieve the standards of oil-free, water-free, dust-free, and bacteria-free compressed air.

Pain Point 2

Piston compressors consume high energy, and their components are prone to wear and tear, leading to a continuous decline in performance and the failure to meet production targets.

Solution

Based on the project engineer's site survey and analysis, the proposed replacement solution involves using 6 Xinlei magnetic levitation centrifugal compressors to replace the original 10 piston compressors. Featuring semi-permanent operation, frictionless design, and lubrication-free maintenance, these machines will experience no performance degradation throughout their lifecycle. Compared to the original equipment, they achieve approximately 35% energy savings, significantly reducing operating costs while enhancing system stability.
