How much air consumption is generally required for bottle blowing machines

the air consumption of the bottle blowing machine is not a fixed number, it is directly related to the size of the machine, how many bottles can be made at a time, and the speed of production. The following is explained in the most understandable way.

First of all, the semi-automatic bottle blowing machine is small in size and low in output. It makes about 300 to 800 bottles per hour. It needs about 0.3 cubic meters of compressed air per minute. It is a relatively gas-saving type and is suitable for small-scale production or start-up scenes.

Besides, the full-automatic bottle blowing machine, that is, the medium and large-scale mass production model that can make four bottles at the same time, can make 2,000 to 4,000 bottles per hour, and the gas consumption is about 0.6 cubic meters per minute. This kind of machine is used more often in medium-sized beverage factories.

The large-scale and high-efficiency model, which is fully automatic and produces six bottles at a time, can produce 8,000 to 15,000 bottles per hour, and the gas consumption can rise to 1.2 cubic meters per minute.

There are also some high-speed linear bottle blowing machines with higher output. A single bottle can produce 6000 or 7000 bottles per hour. The gas used to drive the cylinder alone needs two to three cubic meters per minute, while the high-pressure gas used to blow the bottle embryo into a bottle needs an additional three to six cubic meters per minute. Together, the total gas consumption can reach 1.8 cubic meters per minute or more.

In addition, it should be noted that there are two kinds of gas used in bottle blowing machines. One is used to drive the cylinder, manipulator, demoulding these actions, can be called action gas. The other is to blow directly into the bottle embryo to support the bottle, which can be called blowing bottle gas. Bottle blowing gas requires very high cleanliness of the air, because this part of the air will directly contact the inner wall of the preform. If there are oil or impurities in the air, it will pollute the bottle, and the bottle may have peculiar smell, black spots, and even affect the safety of the subsequent filling of food or beverage.

This is why the bottle blowing machine is particularly suitable for use with water-lubricated air compressors. The water-lubricated air compressor does not use lubricating oil, but uses water to complete the lubrication and sealing of the internal parts of the machine, so there is no oil in the compressed air produced. Water forms a layer of water film in the machine, separating the moving parts, which not only reduces friction and wear, but also takes away the heat generated during compression. Although the air will bring some moisture, but as long as the back with drying equipment to remove the moisture, you can get very pure, completely oil-free compressed air, fully meet the requirements of the bottle blowing gas clean.

In the whole air supply scheme, the water lubricated air compressor is generally used together with drying equipment and precision filtration equipment. Ordinary quality air can be used in the action gas link, while the bottle blowing gas link uses water to lubricate the high quality oil-free air provided by the air compressor, which not only ensures the quality and safety of the bottle, but also does not cause energy waste. For the bottle blowing plant this year-round non-stop, strict air quality requirements of the production environment, water lubricated air compressor is a very suitable choice.
