Compressed air requirements for biological fermentation industry

Fermentation process is the use of microorganisms in aerobic or anaerobic conditions of life activities or direct metabolites or secondary metabolites of the process. The so-called fermentation, mostly refers to the process of organic matter decomposition, fermentation is a biochemical reaction of human contact earlier. In recent years, with the progress and development of industrial biotechnology and process control technology, biological fermentation has developed rapidly in food (red wine, lactic acid milk, yogurt, etc.), biopharmaceutical and chemical industries. For the fermentation process and related industries, the gas in the fermentation process needs strict monitoring, and the air indicators have strict standards.

The screw air compressor is used for industrial fermentation production to provide clean, oil-free compressed air for the fermentation tank. The air quality of bacteria fermentation production has high requirements on sterility, oil-free, temperature, pressure and humidity. That in the biological fermentation industry, compressed air system specific need to consider what factors?

1. The demand for energy saving is prominent.

Electricity consumption accounts for about 80% of the total energy consumption of the fermentation plant; considering the operating conditions of the fermentation machine and the actual demand for compressed air, choosing a suitable air compressor can not only ensure product quality, but also save energy to the greatest extent. According to the requirements of compressed air for different fermentation time, according to the oxygen demand and the characteristics of biochemical reactions of different microorganisms, the changes required by a single fermentation tank during the fermentation process are considered. On the basis of considering the adjustable range, through the calculation of the large z, small z and average requirements of compressed air, the number of air compressors and single air volume are selected to avoid unnecessary energy waste during the use of screw air compressors.

2, the pressure is relatively stable.

The pressure in the brewing industry is generally stable, the pressure range is about 0.3-3.5bar, and most of them are between 1.8-2.5bar. The working pressure of the air compressor depends on the height of the material surface in the fermentation tank. Top back pressure of fermentation tank. Passenger channel pressure drop, water removal/sterilization device pressure drop.

In short, the requirements of the screw air compressor system in the field of biological fermentation mainly include: sterile, oil-free, water-free, pressure, suitable temperature, etc.
