Project Background
The customer is a food manufacturer located in Slovenia, specializing in high-end bakery premixes and functional food powder products.
During production, the customer faced problems caused by uneven powder particle size distribution. These issues affected product solubility, mixing uniformity, and final product quality.

The customer required a reliable screening system to separate food powders into three particle sizes:
800μm (20 mesh), 350μm (45 mesh), and 250μm (60 mesh).
The equipment also needed to meet strict EU food contact material requirements.
Sanyuantang Food Powder Screening Solution
According to the characteristics of the customer’s materials, including powder dust generation and agglomeration tendency, Sanyuantang supplied the SY-800-3S Rotary Vibrating Screen.
The equipment adopts three-dimensional rotary vibration movement, combining horizontal circular motion, vertical axial vibration, and inclined vibration.
This movement creates a spiral travel path on the screen surface, increasing material residence time and improving screening accuracy.
To solve fine powder blockage problems, the machine is equipped with a food-grade bouncing ball cleaning system. The continuous impact of the balls under the screen mesh keeps the screen surface open and ensures stable processing capacity of 200 kg/h.
Product Configuration

Why Choose Rotary Vibrating Screen for Food Powder Screening?
Traditional inline sifters often have difficulties in food powder applications, especially with screening accuracy and frequent mesh blockage.
The SY-800-3S Rotary Vibrating Screen provides several advantages:
- High screening accuracy:
The three-dimensional vibration allows materials to spread and separate effectively on the screen surface, improving classification accuracy. - Continuous screen cleaning:
The bouncing ball system automatically removes particles trapped in the mesh openings, reducing manual cleaning frequency. - Multi-layer classification:
The three-layer structure allows one feeding process to separate different particle sizes, saving production space and improving efficiency.
Project Results
After installation and commissioning on January 15, 2026, the equipment successfully passed customer acceptance.
The Food Powder Screening Solution achieved the following improvements:
- Improved Product Quality
- The customer replaced outsourced screening processing with internal powder classification. The particle size consistency of raw materials was significantly improved, resulting in more stable bakery product performance.
- Reduced Operating Cost
- The automatic screen cleaning system reduced downtime caused by manual cleaning. The equipment efficiency improved, while screen service life increased and maintenance costs were reduced.
- Improved Production Flexibility
- With the quick-change screen frame design, customers can replace different mesh sizes within approximately 15 minutes when switching product formulas, improving production flexibility for multiple powder products.

Conclusion
This project successfully solved the customer’s food powder classification challenge and demonstrated the reliability of the Rotary Vibrating Screen in food powder processing applications.
For industries requiring strict hygiene standards and precise particle classification, including food, chemical, and pharmaceutical industries, Sanyuantang provides reliable powder screening solutions based on actual application requirements.

FAQs
1. What is a Food Powder Screening Solution?
A Food Powder Screening Solution is a complete powder classification system designed to separate food materials into different particle sizes according to production requirements. It usually includes screening equipment, suitable mesh selection, cleaning systems, and customized configurations to achieve stable and accurate powder separation.
2. What food powders can be processed by a vibrating screen?
Food-grade vibrating screens can process various powder materials, including flour, starch, sugar powder, additives, baking ingredients, spices, and other dry food powders. The equipment design depends on material characteristics such as particle size, moisture content, flowability, and dust generation.
3. Why was the SY-800-3S Rotary Vibrating Screen selected for this food powder project?
The SY-800-3S Rotary Vibrating Screen was selected because it provides accurate particle classification, multi-layer screening capability, and continuous screen cleaning performance. Its 304 stainless steel contact parts and food-grade sealing design also meet strict hygiene requirements for food processing applications.
4. How does a Rotary Vibrating Screen improve flour screening efficiency?
A Rotary Vibrating Screen uses three-dimensional vibration movement to create a spiral material flow on the screen surface. This increases the contact time between powder materials and the mesh, improving screening accuracy and reducing the possibility of uneven particle separation.
5. What particle sizes can be separated by this food powder screening system?
In this Slovenia project, the SY-800-3S Rotary Vibrating Screen separated food powder materials into three particle sizes: 800μm (20 mesh), 350μm (45 mesh), and 250μm (60 mesh). Different mesh sizes can be selected according to specific production requirements.
6. Can Sanyuantang provide customized food powder screening solutions?
Yes. Sanyuantang provides customized screening solutions based on material properties, required particle sizes, capacity requirements, and hygiene standards. Customers can also request material testing before selecting the final screening equipment.
