The Outstanding Application of Helical Mixer in Protein Powder Production

The Outstanding Application of Helical Mixer in Protein Powder Production

In the fast-developing health industry, protein powder a key nutritional supplement has become part of daily diets for athletes, fitness enthusiasts and the general public. The uniformity and safety of its production directly affect the final quality of the product and the health of consumers.

Protein powder is a powdered nutrient made from proteins extracted, concentrated, and dried from sources such as whey, soybeans, and peas. Its main characteristics include:

1. Fine powder
2. Difference in specific gravity
3. Prone to absorbing moisture and forming lumps
4. High uniformity and high requirements

These characteristics pose extremely high requirements for mixing equipment: it must achieve gentle, efficient, and seamless mixing, while eliminating stratification and lumps.

Working principle:

Specifically, the screw mixer operates through an internally designed spiral belt mechanism. When the equipment starts, the external spiral belt pushes material from both ends to the center, and the internal one conveys it from the center to both ends. These opposing flows create convection, shearing, and diffusion mixing effects, ensuring highly uniform material mixing in a short time.

Key features:

1. Uniform and efficient mixing: 3-15 minutes per batch, with a uniformity of over 95%, quickly eliminating material stratification;
2. Wide material compatibility: Can handle powders, granules, and low-viscosity paste-like materials, with stable mixing of materials with small density differences;
3. Low residue & easy cleaning: Full-width bottom discharge door + smooth inner walls for convenient cleaning.
4. Expandable functions: Can be equipped with heating/cooling jackets, spray devices, etc., suitable for various production scenarios;
5. Stable operation and easy operation: Mature structure with low failure rate, parameters can be set, suitable for batch production.

Beyond high-quality screw mixers, we have strong project planning, integration and delivery capabilities to design and implement full customer production lines.

Take the protein powder production line that we successfully delivered to our Australian customers as an example. This production line includes:

Dust-free feeding station (line start): Eliminates manual feeding dust, maintains a clean follow-up environment and safeguards employee health.

Screw conveyor: Stably and quantitatively transports raw materials horizontally from the feeding station to the next stage. The structure is simple and the operation is reliable.

Pneumatic vacuum feeder: Uses negative pressure to efficiently convey materials long-distance via sealed pipelines to the screw belt mixer’s storage bin. The entire process has no dust and no pollution, achieving the automated circulation of materials.

Screw belt mixer: It is responsible for precisely and evenly mixing various raw materials to ensure the core of product quality.

We integrate these devices via our central control system, enabling automated, intelligent production from material feeding, transportation, mixing to packaging. This significantly enhances the production capacity and product consistency for customers, while reducing labor costs and operational risks.
