The cleanliness requirements for compressed air in the food and pharmaceutical industries are the strictest of any industry. Simply put, the air required by these two industries should be as clean as possible, the oil content should be so small that it can hardly be detected, and the dust particles should be controlled in a very small range.
So is it enough to reach a cleaner gear. The answer depends on where it is used.
If it is used in direct contact with food, such as filling and packaging, compressed air will directly touch the product, then the cleanest gear must be used, no oil can be used, and dust should be as little as possible. In this case, no oil and water lubrication air compressor is the most suitable choice. Because they do not use oil from the source, the air produced is naturally very clean and does not need to be followed by a bunch of filtering equipment.
Water lubricated air compressor is especially suitable for this kind of scene, because water participates in the whole process of compression, which not only takes away heat but also completes lubrication, and there is no oil component in the gas. With the right filtration device, it can easily meet the most stringent cleanliness requirements of the food and pharmaceutical industries.
If it is used in the clean workshop of pharmaceutical production, the requirements for air are also very high, and the cleanest file is also needed. Because even a little oil mist or tiny particles can affect the quality and safety of the drug. Oil-free water-lubricated air compressors can also play a good role here, because without the participation of oil, the air is very pure from the moment it is produced.
However, if it is only used in some auxiliary links, such as purging and transporting places that do not directly contact the product, then the cleaner air may be enough. For example, in the workshop, compressed air is used to blow the ground and push the materials. In this scenario, the requirements for air cleanliness are not so harsh.
So you can't generalize as long as it's cleaner. In the food and pharmaceutical industries, the cleanest air must be used in the direct contact with the products, while the requirements for the auxiliary links can be appropriately relaxed.
Oil-free water-lubricated air compressors have a great advantage, that is, they can provide the cleanest air and can be flexibly adjusted according to actual needs. If a certain link only needs relatively clean air, the machine can run on demand without causing waste. If a link needs the cleanest air, they are also fully capable.
To sum up, the food and pharmaceutical industries cannot cope with all scenarios with relatively clean air. The place in direct contact with the product must use the cleanest gear, and the auxiliary link can use the cleaner gear. Oil-free water-lubricated air compressors are a reliable choice to meet these different needs. They fundamentally solve the problem of oil pollution and make food and pharmaceutical production more comfortable.
Under the background of energy saving, emission reduction and efficient production, the frequency conversion direct screw air compressor has gradually become the preferred equipment in the industrial field with its excellent performance and remarkable energy saving effect. In particular, the water-lubricated screw air compressor produced by Shanghai Granklin Group is more
Screw air compressor permanent magnet frequency conversion technology has a number of advantages, the following is a detailed summary of its characteristics: high efficiency and energy saving: the use of advanced gas control technology, compared with the traditional air compressor, screw air compressor permanent magnet frequency conversion in the same exhaust pressure can be more than 20 output
Color steel plate production does need to use the air compressor. Air compressor plays an important role in the production of color steel plate, mainly used to provide compressed air, which is used in many production links. Specifically, the role of air compressor in the production of color steel plate may
Air compressor general working pressure is 0.7 ~ 0.8MPA. Air compressor is a kind of equipment used to compress gas. Air compressors are similar in construction to water pumps. Most air compressors are reciprocating piston type, rotating blade or rotating screw. Centrifugal compressors are
When choosing an air compressor, the question of whether to use two frequency converters or fixed frequencies actually depends on a number of factors, including use requirements, energy efficiency considerations, cost budget, and maintenance convenience. First of all, from the point of view of energy efficiency, variable frequency air compressors usually have higher energy.
After the recommended service life of the air compressor tank is reached, it is not necessarily only scrapped. The specific treatment method depends on multiple factors. The following is a detailed answer to this question: The meaning of the recommended service life The recommended service life of the air compressor gas tank is usually based on the design and manufacturing
Many people think that oil-free air compressors are truly oil-free, but this is not the case. Usually we think that the oil content of the oil-free air compressor is 0.01ppm, while the oil content of the screw machine we usually use is about 3ppm, which we will recognize above this standard.
Gas compressor as a kind of mechanical energy into gas pressure power device, has a wide range of applications in many industries. The following are some types of companies that use gas compressors: 1. Manufacturing Automobile Manufacturing: In the automobile manufacturing process, gas pressure
During the operation of the air compressor, condensed water will be generated due to air compression and temperature changes. If it is not properly treated, it may cause pipeline corrosion, equipment wear and pollution at the gas end. The following from the moisture generation mechanism,
The "oil-free" of an oil-free compressor means that no lubricating oil is used for lubrication during the compression process, thereby ensuring that the compressed air produced is low in oil. However, in practical applications, due to the trace amount of oil vapor in the environment, the internal parts of the compressor
