The principle and application of protein powder mixing by helical ribbon mixer

In the production of food and nutritional supplements, specifically, the quality of protein powder mixing directly affects product quality. The helical ribbon mixer stands out with its unique structure and high efficiency.

The equipment’s core comprises a U-shaped cylinder and inner/outer helical ribbon stirring shafts with reverse helices. During operation, the inner screw ribbon pushes central material to both ends, while the outer screw ribbon gathers cylinder-wall material toward the center for convection. Combined with material tumbling and shearing, it enables three-dimensional mixing, efficiently breaks up lumps, and ensures uniform mixing.

 The mixing process has three steps: control feeding speed and sequence, add a small proportion of functional protein powder after premixing, and set stirring time (5-15 minutes) and speed according to material characteristics during mixing to prevent dust and low efficiency. Discharge must be prompt and thorough to prevent residues from interfering with subsequent batches.

The advantages of the helical ribbon mixer are obvious: high uniformity of mixing, ensuring the uniform distribution of multiple components; Applicable to powders with different physical properties; Low energy consumption and cost reduction; The operation and maintenance are simple, and the failure rate is low. A certain enterprise used this equipment, which reduced the coefficient of variation of the protein powder’s uniformity to less than 3% and improved both quality and output. During use, parameters should be set in accordance with the characteristics of the materials. After operation, clean to prevent contamination. Regularly inspect the wear of components and replace them in a timely manner to ensure that the equipment continues to play an important role in protein powder production.
