What is the different between ultrasonic batch/cleaner and ultrasonic probe machine for liuqid treatment?

Ultrasonic cleaning principle: mainly based on the physical effects such as cavitation effect, radiation pressure and mechanical vibration generated when ultrasonic waves propagate in liquids. Cavitation bubbles are generated, grown and collapsed in liquids, generating strong impact force, which can remove dirt, particle impurities and other impurities on the surface of objects. For example, when cleaning eyeglass lenses, ultrasonic cavitation can remove pollutants such as dust and grease attached to the surface of the lenses. ​

Ultrasonic sonochemical principle: In addition to the cavitation effect, it emphasizes the use of extreme physical and chemical environments (such as high temperature, high pressure, high-speed microjets, etc.) generated during the cavitation process to trigger chemical reactions. In solution processing, these conditions can significantly change the activity and reaction rate of molecules in the solution. For example, in organic synthesis reactions, ultrasonic waves can cause the chemical bonds of reactant molecules to break and recombine, thereby achieving chemical reactions that are difficult to carry out under normal conditions. ​

Poor extraction effect
Lack of targeted parameter adjustment: The main design purpose of ultrasonic cleaning machines is to clean dirt on the surface of objects. For solution extraction work, its parameter adjustment is very limited. Taking the extraction of effective ingredients from Chinese medicinal materials as an example, professional extraction equipment can accurately control temperature, pressure, solvent flow rate, etc., and optimize extraction conditions according to the characteristics of medicinal materials. However, ultrasonic cleaning machines can only simply adjust the power and time. Unlike professional equipment, they cannot set appropriate extraction parameters according to the cell wall structure of different medicinal materials, the chemical properties of the active ingredients, etc., resulting in low extraction efficiency.
Low extraction rate and long time: Compared with professional extraction devices such as Soxhlet extractors, the extraction rate of ultrasonic cleaning machines is obviously insufficient. Soxhlet extractors can continuously extract the extracts through repeated reflux of solvents, greatly improving the extraction efficiency. Ultrasonic cleaning machines use cavitation to extract. Although the cavitation effect can destroy the cell structure, it cannot achieve efficient recycling of solvents and extracts like professional equipment, which greatly prolongs the extraction time. At the same time, the extraction rate is difficult to reach the ideal level. It is not suitable for large-scale production or scenarios with high requirements for extraction volume.

Limited dispersion capacity
The processing volume is difficult to meet the demand: the amount of solution dispersion required in industrial production is often large, while the working tank volume of ultrasonic cleaning machines is generally small. In the production of coatings, a large amount of pigments need to be evenly dispersed in the solvent to form a stable coating solution. The amount of solution that an ultrasonic cleaning machine can process at one time is far from meeting the production scale. Frequent operation is not only inefficient, but also increases production costs and time costs.
Poor treatment effect of special solutions: ultrasonic cleaning machines are unable to cope with high-concentration and high-viscosity solutions. In the production of inks, the ink solution has high viscosity characteristics. When ultrasonic waves propagate in such solutions, the energy decays rapidly, and cavitation bubbles are difficult to effectively generate and collapse, resulting in the inability to fully exert the cavitation effect, effectively break up particle agglomerates, and achieve uniform dispersion, which ultimately affects product quality.

Different effects produced​
Ultrasonic cleaning effect: focuses on physical cleaning effects. Its main function is to clean the surface of objects, separate pollutants from the surface of objects and disperse them in the solution, but the chemical properties of the solution itself are slightly changed. For example, cleaning the oil stains on the surface of metal parts only peels off the oil stains from the surface of the parts into the cleaning solution, and the chemical composition of the cleaning solution remains basically unchanged. ​

Ultrasonic sonochemical effect: not only can physical dispersion be achieved, but also a series of chemical changes can be triggered. The high temperature (about 5000K) and high pressure (about 100MPa) environment generated at the moment of cavitation bubble collapse can promote the cracking of molecules in the solution, the generation of free radicals and other reactions. For example, in wastewater treatment, ultrasonic sonochemistry can produce strong oxidizing free radicals to oxidize and decompose difficult-to-degrade organic pollutants into harmless small molecules, thereby achieving a deep change in the chemical composition of the solution. ​
Different application scenarios​
.Ultrasonic cleaning application scenarios: Applicable to situations where dirt and impurities on the surface of objects need to be removed and the cleanliness of the surface of objects needs to be restored. It is commonly used in the fields of electronic component cleaning and pretreatment before medical device disinfection. It mainly focuses on the surface cleaning of objects and does not require high depth of solution treatment. ​

Ultrasonic sonochemistry application scenarios: Widely used in scenarios where solutions need to be chemically modified and chemical reactions need to be promoted. In material synthesis, it can be used to prepare nanomaterials, and the particle size and structure of the materials can be precisely controlled through chemical reactions triggered by ultrasound; in the field of environmental remediation, it is used to treat contaminated water bodies and deeply purify solutions.
