Jetstream


JETSTREAM

Set-up and function

The principle of the Jetstream mixer is based on the rotor-stator-system.

  • a fast rotating rotor produces a directed liquid stream.

  • a guiding tube surrounds the rotor.

  • it directs the liquid stream towards the bottom of the vessel.

  • rotation of the liquid in the vessel is avoided.

  • the liquid stream is directed towards the bottom of the vessel where it is redirected to an upward stream.

  • on the surface, the stream again is redirected towards the bottom of the vessel.

  • in such a manner, the whole contents of the vessel is mixed and homogenized.

Information and principle

  • In the mixing technology we distinguish between Micro- and Macro mixing.
    Micro mixing describes the turbulence that reaches even the smallest particles and ensures a complete homogeneous medium in even the smallest spot.

  • Macro mixing circulates and homogenizes the whole volume without any dead zones.

  • The ideal situation would be to have a good macro mixing and simultaneously a good micro mixing.

  • It does not make any sense to use an stream lined and optimized stirring element, that provides a slow circulation of the contents of the vessel, but that canít provide a sufficient micro mixing - nor is it useful to have a mixer, that starts to rotate the liquid, but is not able to mix the upper and lower layers of liquid.

Advantages of the Jetstream mixer
   

- no rotation of the contents in the vessel;
 
- absolutely no sedimentation for suspensions;
 
- no incorporation of air from the surface;
 
- gentle mixing because of a homogeneous mixing effect
no open rotor system;
 
- side entry installation in large vessel;

Field of applications for Jetstream mixers

  • Ystral Jetstream mixers are being used in all branches of the chemical industry, pharmaceutical productions, food industry and cosmetic products.

  • The machines are designed according to given specifications of the product. There is a special designed type for the use in sterile areas as well as others for waste water treatment.

  • Jetstream mixers are used for homogenizing, dispersing, suspending, emulsifying, crystallizing, aeration, dissolving and to improve the rate of heat exchange on the wall of a vessel. They may be attached directly onto a tank or to a moveable lift.

  • Anywhere where real homogeneous mixtures are required a Jetstream mixer has to be installed.

  • Advantage of a Jetstream mixer is that no additional installations, such as baffles are required.

  • The mixing effect is so efficient, that a relatively small mixer is sufficient to keep large volumes in motion (storage tanks for milk, vessels with raw mineral oil).

  • Side entry mixers are installed close to the bottom of the tank to circulate all the liquid.
