6.What is the Operational Principle of the Ribbon Mixer?

The operational principle of a ribbon mixer is based on its efficient blending properties using a spiral agitator that unifies the material in a stainless steel pan. The distinctive structure and movements of ribbon blades guarantee the meticulous blending of constituents via combined effects of convective and shear blending.

Blending Mechanism

The two combined blending forces established in the ribbon mixer assist in the formation of a consistent blend:

Convective Blending The rotary motion of the agitator results in the upright and sideways movements of the material within the pan. This convective action enables the mass movement of the ingredients, making different parts of the blend effectively adhere.

Shear Blending The close gaps between the blades and the pan walls develop a shearing action, forcing the item against the wall. This crushing force guarantees that small fragments are dispersed uniformly throughout the blend by dissolving lumps.

Blending Process

Material Loading

Materials are loaded into the device through an inlet positioned atop. Different constituents are added simultaneously or sequentially as per the formulation guidelines. The material level within the pan is usually maintained at 40-70% to guarantee effective blending.

Agitation

The device is then turned ‘ON’ and the motor starts moving the agitator blades via the gearbox at the regulated pace, creating a uniform mix.

Blend Discharge

Once the desired homogeneity is achieved, the blend is discharged from the pan through an outlet typically placed at the bottom. For batch-to-batch uniformity and simplicity of maintenance, the outlet's layout permits full basin drainage with the least amount of sediment.

7.What Types of Ribbon Mixers Are Available?
