Oil content of fermentation air by screw air compressor

In the fermentation industry, the oil content of the compressed air produced by the screw air compressor needs to be strictly controlled at a very low level, generally less than 0.01ppm (I. e. 0.00001 mg/m & sup3;) to meet the stringent requirements of the fermentation process for cleanliness. The following is a specific analysis:

standard and requirement for oil content of 1.

The fermentation industry requires high cleanliness of compressed air, because oil pollution may pollute the fermentation flora and affect the fermentation effect and product quality. Therefore, the compressed air produced by the screw air compressor must be efficiently filtered and separated to ensure a very low oil content. In general, the fermentation industry requires that the oil content of compressed air should be less than 0.01ppm, which is much lower than the oil content requirements for general industrial applications.

Influence of 2. oil content exceeding standard

if the oil content of the compressed air produced by the screw air compressor exceeds the standard, it may have the following adverse effects on the fermentation process:

1. contamination fermentation flora: Oil pollution may adhere to the fermentation flora, affecting its activity and reproductive ability, thereby reducing the fermentation efficiency.
2. Affect product quality: Oil pollution may enter the fermentation product, affect the purity and quality of the product, and may even cause harm to human health.
3. Damage to equipment: Oil pollution may block pipelines and valves, affect the normal operation of equipment, and increase maintenance costs.

3. Measures to Reduce Oil Content

in order to reduce the oil content of the compressed air produced by the screw air compressor, the following measures can be taken:

1. selection of high-efficiency oil and gas separator: The oil and gas separator is a key component to reduce the oil content of compressed air. The oil and gas separator with high filtration accuracy and good separation effect should be selected, and the filter element should be replaced regularly to ensure its filtration effect.
2. Optimized cooling system: The heat dissipation effect of the cooling system directly affects the oil content of the compressed air. The cooling system should be inspected and maintained regularly to clean up the accumulated dirt and oil residue to ensure good heat dissipation.
3. Control the amount of oil added: When using the screw air compressor, control the amount of oil added to avoid excessive use. Reasonable control of the amount of added can effectively reduce the oil content of compressed air.
4. Adopt oil-free screw air compressor: For scenarios that require extremely high cleanliness of compressed air, such as the fermentation industry, an oil-free screw air compressor can be considered. Oil-free screw air compressor through a special design, to achieve the compression process without oil participation, thus completely eliminating the risk of oil pollution.
