Continuous ultrasonic homogeniser for liquids or slurries - with vibrations applied through a tube fixed at one end

摘要

Liquid flows through a vertical tube one end of which is firmly fixed whilst the other is free to move. An ultrasonic oscillator is in contact with the tube wall, and is supported through an external jacket. Within the tube and the jacket are horizontal baffles attached to a central post, which direct the liquid in laminar flow past the area of ultrasonic vibrations. Used for the continuous homogenising of liquids or solid suspensions to alter their characteristics or properties. Appts. gives efficient use of energy, has low energy input, and continuous operation.
