Dynamic Inline Mixer

Dynamic mixing with Pin mixing elements
for shear sensitive products



The INDAG Dynamic Inline Mixer type DLM/P is used for homogeneous mixing of shear sensitive and highly viscous liquids. For example, aroma, color or emulsifiers are mixed into fat mass or chocolate mass.  Even with a very small proportion of these additives in the total quantity, e.g. 0.01%, the mixing result will be absolutely homogeneous. Introduced mixing energy will not increase temperature of product more than 1°C. Especially shear sensitive products like aerated foams will not be destroyed by INDAG Dynamic Inline Mixer DLM/P.


Advantages of DLM/P

  • Very good self-cleaning during CIP-cleaning
  • No pressure loss
  • Homogenous mixing result even for extreme concentration ratios
  • Efficient introduction of mixing energy
  • Mixing energy can be changed variable and
    adapted to product or capacity changes
  • Temperature increase less than 1 °C
  • Gentle mixing of shear sensitive highly viscous products
  • Execution with double jacket and further connections possible

Technology of DLM/P

INDAG Dynamic Inline Mixer type DLM/P consists of round shape mixing elements on rotor and in stator (mixer casing). Round shape mixing elements are extremely robust and also allow mixing of highly viscous products (> 1,000,000 mPas). The mixing energy is efficiently introduced into product. Rotor and stator can be designed to be cooled or heated. The DLM/P is offered in compact design (KB) and in bearing block design (LB). In the compact design, the rotor is mounted  by the output shaft of the motor. In the bearing block design, the rotor is mounted by its own bearing block. With a separate bearing block, longer rotors and thus larger mixing volumes can be realized. Furthermore, this design is also suitable for mixing under high pressure or high temperature. The type of rotor seal is selected to suit each application. For the supply of the double-acting mechanical seal INDAG offers the suitable barrier fluid system.
