This device is used for mixing several types of seeds or products and also for flavoring (oiling) during mixing. Stirring products such as tea and roasted coffee beans with minimal damage to them is the main advantage of this device.

Rotary blenders, also known as rotary drum blenders, lack blades or paddles inside. Instead, the interior of the rotating drum features welded blades, which eliminates the need for moving parts within the mixer.
Rotary mixers use knobs instead of faders, offering smooth, precise control, ideal for house and techno DJs who prefer gradual transitions. Analogue mixers are renowned for their warm, natural sound, appealing to purists who prioritise audio quality.
