Air source of bottle blowing air compressor

Bottle blowing process is very demanding on the compressed air, because the compressed air will be blown directly into the bottle blank, and eventually become a container for food and beverage, even if there is a little bit of oil or moisture in the air, the bottle will be wasted.

Let's talk about the core requirements of blowing bottles for gas sources. The first is absolutely no oil, the bottle is used to hold food and drink, oil mist once mixed in is a food safety accident. The second is extremely dry, moisture will make the bottle wall appear bubbles, white, strength decreased, directly affect the appearance and quality of the bottle. The third is dust-free and sterile. Particles and bacteria will adhere to the bottle wall, and the contents will be contaminated during subsequent filling.

How does the gas source of the bottle blowing factory generally match.

The core equipment is the air compressor, which must be oil-free. Now the mainstream program is water lubricated oil-free screw air compressor. Its working principle is well understood. The single screw and star wheel inside the machine rotate to compress air. In this process, oil is not used to reduce friction, but water. The water inside lubricates the screw while taking away the heat generated by compression, so the air that comes out is completely oil-free. Because there is no need for oil, no need to change oil or treat waste oil in the later period, the condensed water discharged is clean water, no sludge will accumulate in the pipeline, and maintenance is much easier than that of the oil injection machine.

It is not enough to have an air compressor alone, and drying equipment will be connected behind. Although the air from the air compressor has no oil, it has a high water content. It must be removed by the dryer to make the air very dry, so that the bottle blown out will not have water mist and bubbles.

Then there is the filtration system, which is usually equipped with multi-stage filtration. First, large particles and impurities are blocked, then activated carbon is used to adsorb peculiar smell, and finally a precision filter element is passed to block particles and bacteria in the air to ensure that the air sent to the mouth of the bottle blowing machine is really clean.

Finally, it is also equipped with a gas tank to stabilize the pressure. The pressure of the bottle blowing machine must be stable every time the air is taken, and cannot be high or low, otherwise the wall thickness of the bottle will be uneven, some places will be thin and some places will be thick, and the product will not be qualified.

In short, the core of the air source in the bottle blowing factory is the combination of water lubricated oil-free screw air compressor, drying and multi-stage filtration. Because the bottle is in direct contact with the food, the air quality cannot tolerate the slightest sloppiness. Although the initial investment of this set of configuration is higher than that of the oil injection machine, the maintenance in the later stage is simple and the air quality is stable, which is more cost-effective in the long run.
