Ultrasonic emulsification equipment refers to a process in which two (or two or more) non-phase solutions are uniformly mixed to form a dispersion system under the action of ultrasonic energy, wherein one liquid is evenly distributed in another liquid to form an emulsion. process. Compared with general emulsification processes and equipment (such as propellers, colloid mills and homogenizers), ultrasonic emulsification has the characteristics of high emulsifying quality, stable emulsion, stable emulsion products and low power required.
Principle of ultrasonic emulsification equipment: The physical mechanism of pulverizing insoluble solids (or liquids) is considered to be ultrasonic cavitation. Ultrasonic cavitation effect means that under the action of strong ultrasonic waves, a large number of bubbles will be generated in the liquid. The small bubbles will gradually grow and increase with the ultrasonic vibration, then suddenly burst and split, and the bubbles after the split will continue to grow and burst. . When these small bubbles collapse rapidly, high temperature and high pressure are generated in the bubbles, and due to the high velocity of the liquid around the bubbles, a strong local shock wave is generated in the liquid near the bubbles, and a local high temperature and high pressure are also formed, thereby generating a local high temperature and high pressure. Ultrasonic pulverization and emulsification.
Ultrasonic emulsification equipment is commonly used in the pharmaceutical industry and the daily necessities industry to manufacture a variety of emulsion products, such as emulsion drugs, cosmetics and shoe polish. Ultrasonic emulsification can also be used to make emulsified combustion products of oil (gasoline, diesel, etc.) with water or pulverized coal to increase the combustion value of the unit fuel.
Using a phacoemulsification device, the lens nucleus is pulverized by ultrasonic waves through a corneal or scleral incision of 3-5 mm size, which is nipple-like and then aspirated together with the cortex. After the operation, the posterior capsule of the lens is preserved, and the posterior chamber intraocular lens can be implanted at the same time.
Compared with traditional cataract surgery, phacoemulsification has better surgical results and has become an internationally recognized zui for advanced and reliable cataract treatment.
Ultrasonic emulsification equipment has been used in many fields and plays a unique role in various fields.
There are many applications of industrialized ultrasonic emulsification equipment, and phacoemulsification is one of the techniques used by ultrasonic zui for food processing. For example, soft drinks, ketchup, mayonnaise, jam, artificial milk, baby food, chocolate, salad oil, oil, sugar and other mixed foods used in the food industry have been tested and used at home and abroad, and have been improved. The effect of product quality and production efficiency, and the waterborne carotenoid emulsification has been successfully tested and used for production.
