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

The core of the equipment consists of a U-shaped cylinder and inner and outer helical ribbon stirring shafts with reverse helices. During operation, the inner screw ribbon pushes the material at the center of the shaft to both ends, while the outer screw ribbon gathers the material on the cylinder wall towards the center, creating convection. Combined with the tumbling and shearing of the material, it achieves three-dimensional mixing, efficiently breaks up lumps, and ensures uniform mixing.

The mixing process is divided into three steps: control the speed and sequence during feeding, and add a small proportion of functional protein powder after premizing. During the mixing stage, set the stirring duration and speed for 5 to 15 minutes based on the characteristics of the materials to avoid dust or low efficiency. Discharge must be prompt and thorough to prevent residues from interfering with subsequent batches.

Its advantages 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. After a certain enterprise used it, the coefficient of variation of the uniformity of the protein powder was less than 3%, and both quality and output were improved. 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.
