DLM/M Gentle Inline Mixer
Gentle mixing with paddle mixing elements
for shear sensitive products
INDAG Gentle Inline Mixer type DLM/M is used for gentle mixing of mostly shear-sensitive products. Examples for applications are: mixing fruit concentrate into yoghurt or quark or chocolate into ice cream. Different ingredients can also be gently mixed into foams. A chocolate mousse is made by gently folding chocolate into egg white foam without destroying the delicate foam. Other examples are: mixing caustic lye into vegetable oil for neutralization or mixing aroma into a fat mass.
Advantages of DLM/M
- Very good self-cleaning during CIP-cleaning
- No pressure loss
- No blockage entwining (clog) free
- Very homogenous mixing result
- Variable mixing energy through speed change via frequency converter
- Execution with double jacket and further connections possible
- Gentle mixing of sensitive products
- Special designs, e.g. for high system pressure
Technology of DLM/M
The INDAG mixer type DLM/M has mixing elements on the rotor only. The stator (mixer casing) has no mixing elements. The rotor of the DLM/M mixer can be equipped with different mixing element geometries. The optimum geometry depends on the products to be mixed. The DLM/M 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. In addition to the standard version of the DLM/M an INDAG Gentle Inline Mixer type DLM/M ECO is available. As the name ECO (Economic) already suggests, the mixer can be offered at attractive prices, due to the production in larger quantities. However, in order to achieve larger quantities, the DLM/M ECO is not freely configurable.
