The Role Of Ultrasonic Homogenizer in Degassing Detergent

In the degassing process of dishwashing liquid production, the core function of the ultrasonic homogenizer is to efficiently and thoroughly remove microbubbles and dissolved gases mixed in during production. At the same time, relying on its own homogenizing properties, it also ensures the uniformity of the dishwashing liquid system. It fundamentally solves a series of problems caused by bubbles to the appearance quality, production and filling, storage stability and end-user experience of dishwashing liquid. It is a key piece of equipment for optimizing the degassing process in the large-scale production of dishwashing liquid in the daily chemical industry.

Considering the characteristics of dishwashing liquid formulations (containing a large amount of surfactants, easy foaming, and easily and stably dispersed bubbles), its specific function and core logic are as follows:

1. Thoroughly remove microbubbles, solving the pain points of conventional degassing. In dishwashing liquid production, processes such as stirring, mixing, emulsification, and dispersion introduce a large number of bubbles. Due to the foam-stabilizing effect of surfactants, most of these bubbles are dispersed in the liquid as micron-sized microbubbles. Traditional static settling and simple vacuum degassing methods are insufficient for their rapid removal. Ultrasonic homogenizers achieve precise degassing through cavitation: Ultrasonic vibration causes the dishwashing liquid to undergo alternating compression-stretching cycles. During the stretching phase, tiny vacuum bubbles are formed; during the compression phase, these bubbles rupture instantaneously, generating localized high pressure and micro-jet streams that directly impact and break up the dispersed microbubbles. This causes small bubbles to aggregate into larger bubbles and rapidly escape to the liquid surface, simultaneously removing dissolved gases from the liquid, achieving thorough bubble removal "from the inside out."

2. Improve Product Appearance and Storage Stability

Residual air bubbles can cause dishwashing liquid to appear cloudy, contain flocculent air bubbles, and have poor light transmittance, failing to meet the appearance requirements of supermarkets and customers for daily chemical products. Simultaneously, residual air bubbles can disrupt the density uniformity of the dishwashing liquid system, easily leading to problems such as stratification, viscosity fluctuations, and thickener inactivation during storage, thus shortening the shelf life.

After ultrasonic degassing, the dishwashing liquid becomes clear and transparent, with a uniform system density, effectively preventing quality deterioration during storage and ensuring product stability within the shelf life.

3. Ensure Filling Accuracy and Improve Production Efficiency

Air bubbles occupy liquid volume. Direct filling can lead to inaccurate measurement (overfilling increases costs, underfilling causes customer complaints), and foam overflow during filling, resulting in raw material waste and slowing down the production line.

After ultrasonic degassing, the dishwashing liquid is free of air bubbles, ensuring stable liquid flow during filling. Filling accuracy can be improved to within ±1%, and there is no foam overflow. This matches the high-speed production requirements of automated filling lines, reducing losses and rework in the production process.

4. Degassing and Homogenization Simultaneously, Simplifying Production Processes

The ultrasonic homogenizer is not merely a degassing device. Its core cavitation and micro-jet effects simultaneously degas and homogenize the surfactants, thickeners, additives, and fragrances in the detergent, resolving localized concentration inconsistencies and resulting in more uniform foaming performance, viscosity, and cleaning power.

This is equivalent to completing "degassing + homogenization optimization" in one step, eliminating the need for a separate homogenization process, simplifying the production flow, and shortening the overall production cycle.

5.Adaptable to Industrial Production, Highly Compatible

The ultrasonic homogenizer supports both continuous online degassing and batch degassing modes. It can be directly integrated into detergent emulsification, mixing, and filling production lines, adapting to different production scales from pilot testing to large-scale mass production. Furthermore, it is a non-contact physical process, without adding any additives, and does not alter the detergent's formula or performance, meeting the hygiene production requirements for daily chemical products (such as the production standards for food-grade detergents).
