With the ISO-MIX Mixing Technology introduces a new way of achieving effective liquid mixing. With an ISO-MIX solution it is possible to
• reduce mixing time
• reduce energy consumption
• lower the installation costs
compared to traditional solutions.
In-mixing of smaller volumes of liquid into a larger volume is an area where the ISO-MIX solution offers particular advantages.
The scientific verification of the efficiency of the ISO-MIX Mixing Technology has been established in close co-operation with Professor John Villadsen and his team colleagues at the Technical University of Denmark in Copenhagen.
Requirements for the mixing process differ substantially from one application to another, whether in the brewing, beverage, chemical or biochemical industry. However, the basic system layout is the same for all applications with an ISO-MIX solution (see Figure 1).
Figure 1.
On the left hand side: Outline of the ISO-MIX system. Liquid feed and powder can be added at the suction side of the pump. Gas is added at the pressure side of the pump. The number and type of rotary jet heads depend on the type of application.
On the right hand side: Outline of the ISO-MIX IM 20 rotary jet head (RJH).
When the ISO-MIX system is installed in a tank, it is important to ensure that the effective reach of the jets sweeps the entire tank volume. Figure 2 below shows the reach as a function of the gauge pressure in the recirculation loop and the size of the nozzles, in an application where coal particles are kept in suspension.
Figure 2. Indicates the maximum distance from a jet head at which coal particles remain suspended versus the gauge pressure.
Mixing time dependents on the specific power input delivered to the system. This can be calculated in the following manner:
Specific power input (P/V) is shown in W/m3, while the volumetric flow rate (vl) is shown in m3/h, dp is shown in bar. The higher the power input, the shorter the mixing time.
When mixing one fluid into another, the best way of doing this is by adding the in-mix liquid to the recirculation loop. This will result in substantially shorter mixing times.
