I. Characteristics of Protein Powder and Screening Requirements

Protein powder is a high-nutrition food additive extracted from raw materials such as whey, soybeans, or peas, and is widely used in health foods, sports nutrition products, and medical diets. It has fine powder, good fluidity, but is prone to moisture absorption and caking, and has high hygiene requirements. During production, it needs to be screened to remove impurities and break up lumps to ensure uniformity and quality. Traditional vibrating screens are prone to dust and difficult to clean, while the straight-through screen, due to its unique design, becomes an ideal choice for its screening.

II. Straight-line Vibrating Screen: Working Principle and Advantages

The straight-line vibrating screen is driven by two motors, generating a combined vibration in both vertical and horizontal directions, allowing materials to quickly spread and pass through the screen surface. Its core features include:

1. High-efficiency screening: Materials move in a spiral trajectory on the screen surface, achieving high screening accuracy and large processing capacity.

2. Closed and environmentally friendly: The fully enclosed structure design, combined with silicone rubber sealing rings, prevents dust from escaping and meets the requirements of dust-free workshops.

3. Easy cleaning: The screen box and screen mesh are designed with quick-release clips, allowing for disassembly without tools and meeting food-grade cleaning standards.

4. Multi-functional adaptability: An ultrasonic cleaning system can be selected to solve the problem of protein powder adhering to the screen mesh, improving continuous operation efficiency.

III. Line Empowerment: Comprehensive Solutions from Single Machines to Production Lines

We not only offer high-performance straight-through sieving equipment but also have the capability to customize entire production lines. Taking the Australian customer project as an example, we designed a complete production line for protein powder processing, which includes:

1. Dust-free feeding station: Utilizing negative pressure dust removal technology to ensure zero dust overflow during the protein powder feeding process;

2. Straight-through sieve: Completing the impurity removal and grading screening of raw materials;

3. Screw conveyor: Sealed transportation of the powder after sieving to prevent cross-contamination;

4. Screw ribbon mixer: Achieving uniform mixing of protein powder and additives to ensure product consistency.

The entire line is equipped with an automated control system, balancing efficiency and compliance (conforming to HACCP and FDA standards), helping customers increase production capacity while reducing labor costs.

Conclusion

The straight-through vibrating screen is a key piece of equipment in the production of protein powder, and the overall coordination of the production line is the core to achieving efficient production. We are committed to providing customized solutions from single machines to complete production lines for global customers, covering design, manufacturing and after-sales support.
