Common Problems with Ultrasonic Degassing and Deoxygenation
Ultrasonic degassing is a technique that utilizes the vibration ability of ultrasound to remove gases from liquids. Its working principle is to transmit high-frequency ultrasonic waves into the processed liquid, forming a large number of tiny bubbles, and using the rupture of these bubbles to carry away the gas in the liquid.
How does ultrasonic degassing work?
The function of ultrasound is to convert gases dissolved in a liquid and small bubbles suspended in the liquid into large bubbles with high buoyancy. When these large bubbles rise to the top of the liquid (batch configuration) or are carried along with the flow to the top of the storage tank (flow configuration), they explode and release gas. If using a loop configuration, care must be taken not to send any large bubbles back to the ultrasonic processor. This can be achieved by extracting liquid from the bottom of the tank and then returning it as lightly as possible to the top.
What are the advantages of flow mode degassing compared to batch processing mode?
The flow mode makes it possible to handle larger volumes of liquids. This process is also faster and more complete. In addition, precise temperature control of liquids can be achieved through flow patterns, which can be achieved by using cooling jackets in the reactor chamber or separate heat exchangers
Is there any relationship between viscosity and the time required for the process (e.g. linear)?
There is no simple correlation between degassing time and viscosity, as there are several factors at play. Time almost always increases with the increase of viscosity.
What are my options if a 3000W industrial scale processor cannot handle my fast processing speed?
You can use multiple 3000W industrial scale processors simultaneously, and there is no limit to the number of units used in this way.
What viscosity can FUNSONIC ultrasonic processors remove air from liquids to?
In the case of high viscosity, the pumping process will slow down, pumping becomes difficult, and newly formed large bubbles are also less likely to surface. There are some design adjustments that can be used to handle high viscosity materials, which can help accelerate the process. For example, placing the gas storage tank in a slight vacuum state can help the returning large bubbles stay on the surface and rupture.
What is the typical processing speed for degassing hydrocarbons and hydraulic oil? Is 1000-3000 liters/hour possible?
Sometimes, a 3000W processor can degas at a speed of 1000-3000 liters per hour, but in the case of hydraulic oil, multiple systems may be required. This is due to the high viscosity and complex composition of oil. The rate will also depend on the required degree of degassing. Without proper testing and optimization, it is difficult to estimate the speed.
I want to remove the air from the juice. However, we do not want the viscosity of the juice to be altered. Can I use FUNSONIC's ultrasonic processor for this?
Due to the adjustable ultrasonic intensity between 20-100%, you can find settings that do not change the viscosity of the product during the degassing process. During this process, it is recommended to use gentle independent stirring (such as using a magnetic stirrer).
Can you estimate how long it will take to pack our materials into a 5-gallon container?
This depends on the properties of your material and the amount of trapped air. It also depends on the efficiency of independent mixed arrangements. Without testing, it is impossible to predict the degassing rate.
Does the presence of dispersed solids with a size of 50 microns affect degassing behavior?
No problem, our equipment is often used for degassing suspended solid particles. Ultrasonic waves are also a good dispersion method, and you may find that the homogeneity of your product is greatly improved.
