Indonesia 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.

Attenuation mechanism of foam
Under the condition of gravity and pressure difference, the liquid membrane of foam will flow and discharge liquid unevenly, and the gas in the bubble will continue to diffuse and permeate due to the different pressure difference on both sides of the bubble membrane, so the instability of foam itself is mainly reflected from the dynamics. [4]
The attenuation mechanism mainly includes the diffusion of gas through the liquid film and the discharge of liquid from the liquid film. These two properties are inherent attributes of foam itself, and have nothing to do with the existence of surfactant. However, these two attenuation mechanisms only play an obvious role in the initial stage of foam system formation. With the attenuation of foam system, these two effects gradually weaken, making the foam attenuation rate gradually slow. [

Indonesia 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
