What is the most energy efficient mixing method?

Paddle mixers and drum mixers are energy efficient mixers. A paddle mixer has the advantage that the mixing cycle is short. This makes it an energy efficient mixing process. The product is thrown with a paddle mixer, creating a fluidized zone. As a result, the product floats partly in the air and can distribute itself quickly and well in the mixer. Another advantage is that a paddle mixer has little shear forces. So there is little friction in the product. As a result, energy consumption is lower than other mixing processes. No friction also does not lead to a rise in the temperature of the product. With a drum mixer, the drum is set in motion and there are no moving parts in the mixer. This also makes a drum mixer an energy efficient mixing process. The disadvantage of drum mixers is that it is difficult to install them hygienically and dust-proof in a process line. Another disadvantage is that the drum mixer needs shielding because of the rotating parts.
