Hungary The Free of silicone defoamers powder used for beer bottle cleaning and defoaming is also one of these types. This type of cleaning and defoaming agent is developed using silicone polyether as the main raw material, combined with a variety of additives. With low dosage, convenient operation, and easy solubility in water, there is no need to mention the Free of silicone defoamers and foam inhibiting properties. The main thing is to value the good dispersion of such Free of silicone defoamers agents, which will not affect the transparency and appearance performance of the product. Good compatibility with various surfactants used in beer bottle cleaning, while not reducing the cleaning effect, solves the problem of spot residue, and has no side effects on subsequent processing. The amount of defoamer added for beer bottle cleaning is one thousandth to three thousandths, but the final amount should be determined according to the cleaning water volume of different manufacturers and the content of detergent. Powdery defoamer can be added to the foam surface after the powder and water are boiled.

Defoaming mechanism of hydrophobic solid particles
Hydrophobic solid particles in the foam system will first attract the hydrophobic end of the surfactant, making the hydrophobic solid particles become hydrophilic, thus reducing the concentration of surfactant in the foam film and promoting the foam to burst. This defoaming mechanism cannot explain the action mechanism of other defoaming agents, which is too one-sided. [4] Other reasons for the bursting of foam are the impact caused by the expansion of defoamer, the solubilization of surfactant and the collapse of electrolyte, and the bursting of electric double layer on the liquid film surface. [4] It can be seen from the above defoaming mechanisms that each defoamer has different emphasis on different foam systems, but defoaming is achieved by destroying the stability factors of foam
Hungary It is also worth noting how to select Free of silicone defoamers for beer bottle cleaning. Firstly, they must be insoluble in the foaming liquid and have a lower surface tension than the foaming liquid, so that defoamers can play a role. Then, it should have a certain affinity with the foaming liquid. The defoaming process is actually a competition with the foam production. Only by rapidly dispersing the effect in the starting liquid can we achieve the goal of defoaming. The active component of the defoamer is too hydrophilic to the foaming liquid and will dissolve; Too sparse and difficult to disperse. Only when intimacy is appropriate can effectiveness be good. Finally, it is not allowed to react chemically with the foaming liquid, otherwise harmful substances may breed and affect product performance
