Compressed air standard for mineral water industry

Compressed air standards for the mineral water industry mainly relate to the purity, water content and possible microbial contamination of compressed air. The following is a detailed summary of these criteria:

1. purity standard

the compressed air should be oil-free to ensure that no lubricant oil is mixed into the air flow, thereby avoiding contamination of the mineral water. This requirement corresponds to the ISO 8573-1 standard Class 0, which stipulates that the compressed air produced by the air compressor must be oil-free.

2. water content standard

the relative humidity of the compressed air should be controlled between 40% and 70% to prevent corrosion, condensation or other adverse effects.

Dew point temperature is also an important indicator, which refers to the temperature at which moisture in the air begins to condense under a given pressure. For the mineral water industry, the dew point temperature of compressed air should be lower than the required minimum operating temperature to prevent moisture from condensing in equipment or pipelines. The specific dew point temperature criteria may vary for different equipment and process requirements.

Standard for Microbial Contamination of 3.

Since compressed air may contain microorganisms, it is necessary to control the growth of microorganisms. An effective method is to inhibit the growth of microorganisms by using a dryer with an appropriate pressure dew point. For example, the use of an adsorption dryer with a pressure dew point of & minus;40 ° C. can effectively inhibit the growth of microorganisms.

In general, the mineral water industry has very strict requirements for compressed air standards to ensure product quality and safety. These standards include purity, water content and microbial contamination, and corresponding measures need to be taken to meet these requirements. Please note that specific standards may vary depending on the mineral water manufacturer and process requirements. Therefore, in practical application, the corresponding compressed air standard should be formulated according to the specific situation and strictly implemented.
