MEGATRON MT-MM – Dynamically enhanced membrane machine

Benefits

– Low mechanical and thermal load of the product: Due to the fact that the drop formation is not primarily based on high shear forces or bounce effects a very gentle processing of the product is possible.

– At the membrane emulsifying process, the thermal and mechanical loads having an effect on products are lower than at conventional emulsifying methods around orders of magnitude.

– Double emulsions: The production of double emulsions is without problems possible by the gentle emulsifying process.

– High concentration of contents: By the system of it is possible to produce emulsions with up to approx. 50 % ratio of the disperse phase in one step – defined and reproducible.

– The emulsions arising in this process show also spatially very constant distributions of concentration.

– Low energy consumption: Due to the proportionally low energy which is necessary to receive a certain emulsifying result is also the energy consumption and with that the energy costs related to a produced output much lower.

– Small droplet sizes: Since the membrane pores show only a diameter of 1 – 2 μm, it is possible to produce very small droplets.

– Depending on speed droplets also can be produced due to the special drop formation mechanism in the sub micron area.

– Narrow droplet size distributions: Because of the special drop formation mechanism very narrow droplet size distributions can be reached.

– It is also possible at certain applications and process parameters to produce monodisperse emulsions practically.

– Controllability: The system MEGATRON® MT-MM works after the inline principle.

– Desired throughputs and droplet size distributions can reproducibly be well controlled.

Principal of process

– A MEGATRON® MT-MM machine consists in principle from a cylindrical working chamber in which one a membrane is installed coaxially over a shaft.

– The working chamber has two product inlets, one for the disperse (inner) phase and one for the continuous (outer) phase.

– The disperse phase streams axially into the inside of and will be dispersed into the continuous phase while flowing through the pores of the membrane.

– The drop detachment is additionaly supported by the fast rotation.

– The drop formation or its size distribution depends on the process parameters: Speed, pore diameter of the membrane, viscosity of the continuous phase and the shear gap.

– The formed drops are taken away continuously by the outer phase.
