Vibro Sifter Flour

The Vibro Sifter Flour uses a motor-driven eccentric weight to generate three-dimensional vibration, grading and removing impurities from flour. It typically sieves dry, free-flowing powders such as wheat flour, corn flour, and starch, with a moisture content generally not exceeding 14%. The sieving mesh size typically ranges from 20–200, and the screens can be changed to produce different particle sizes. Output depends on the mesh size, material properties, and machine specifications. Small machines can process approximately 50–300 kg per hour, while large machines can reach 500–1000 kg or more. Common equipment used for Vibro Flour Sifters includes ultrasonic vibrating screens, inline screens, and silo vibrating screens.

The higher the mesh size, the finer the flour particles. Coarse flour (such as whole wheat flour) is approximately 40 mesh, with large particles that retain the bran, resulting in high nutritional value but a rough texture. Regular flour (medium-gluten flour) is between 60–80 mesh and is widely used, ideal for buns, steamed bread, and dumpling wrappers. Fine flour (high-gluten or low-gluten refined flour) is 80–100 mesh, with fine particles, commonly used in bread, cakes, and biscuits. Special fine flour is 100–120 mesh and very fine, often used in pastries and high-end Western pastries. Ultrafine flour, with a mesh size of 120 or higher, has a very powdery feel and is often used in some exquisite desserts or specialty foods.

What are the benefits of the Vibro Sifter Flour?

The Vibro Sifter Flour offers advantages such as suitability for batch processing, multi-stage sieving, wide applicability, and improved flour quality.

High sieving efficiency: The Vibro Sifter Flour uses a vibrating motor to generate high-frequency vibrations, allowing flour to pass through the sieve quickly. Its sieving efficiency is 5–10 times higher than that of traditional manual sifters, making it ideal for large-scale processing. For example, a medium-sized vibrating screen can process 500-1000 kg of flour per hour, while manual sifting can only process a few dozen kg.

Multi-stage screening capability: The Vibro Sifter Flour can be configured with two to five layers of screens with varying mesh sizes, enabling multi-stage screening, such as separating coarse, fine, and ultrafine flours. This design improves screening accuracy and meets diverse particle size and fineness requirements.

High flour purity: The Vibro Sifter Flour's powerful vibrations break up lumps in the flour, while the screen effectively traps impurities such as bran, insect eggs, and foreign matter, ensuring a purer flour. Furthermore, by adjusting the screen mesh size (typically 80-200 mesh), the system can meet the fineness requirements of different flour types (low-gluten, medium-gluten, and high-gluten).

Versatile: The Vibro Sifter Flour can adjust its vibration frequency and amplitude based on the moisture content and viscosity of the flour, making it suitable for difficult-to-sift materials such as whole wheat flour. The screen is easily replaceable, adapting to the needs of flour sieving of varying particle sizes.

Improving Flour Quality: The Vibro Sifter Flour produces flour with a uniform and fine particle size, improving flour processing performance and the final product's taste. It also enhances flour fluidity and reduces clumping, facilitating subsequent packaging and transport.

Vibro Sifter Flour Types

Common types of Vibro Sifter Flour include ultrasonic vibrating screens, inline screens, and silo vibrating screens. The functions of these three devices in the flour sieving process are as follows:

Ultrasonic vibrating screens: Utilize ultrasonic vibration technology to increase the screen's vibration frequency and screening efficiency. They effectively prevent flour particles from clogging the screen, ensuring continuous and efficient screening. They are suitable for fine-grained screening of fine powders, improving flour purity and uniformity.

Inline screens: Utilize linear vibration to evenly distribute flour across the screen, quickly separating particles. They are suitable for sieving flours of varying coarse and fine grains. They offer fast screening speeds and high throughput, making them ideal for primary screening of large batches of flour. They help remove larger impurities and lumps, ensuring flour quality.

Silo-type vibrating screen: Equipped with a silo design, it enables continuous, automatic feeding and screening of flour. The vibrating screen mesh works in conjunction with the silo to reduce flour dust and improve material flowability. It is suitable for multi-stage screening processes, capable of grading flours of varying particle sizes. It improves screening stability and automation, reducing manual intervention.

Vibro Sifter Flour Compatible Equipment

The Vibro Sifter combined with an airflow screen effectively improves flour screening efficiency and accuracy. The vibrating screen quickly separates large impurities, while the airflow screen is used to finely screen ultrafine powder and light impurities after the Vibro Sifter, reducing dust and improving the working environment. Furthermore, this combined screening process protects flour quality, minimizes mechanical damage, and adapts to various flour processing needs.

The Vibro Sifter Flour combined with a screw conveyor achieves integrated flour screening and conveying, improving production efficiency. The vibrating screen efficiently screens impurities, while the screw conveyor stably transports material, reducing dust contamination and material loss. The two work together to save labor and space, reduce energy consumption and maintenance costs, ensure flour quality, adapt to the needs of continuous automated production, and improve overall processing efficiency and production safety.

Vibro Sifter Flour and bucket elevators are commonly used in flour production lines. Bucket elevators lift flour or raw materials vertically to a certain height and convey them to the inlet of a vibrating screen. The vibrating screen removes impurities and particles from the flour through vibration, achieving screening and purification. The combination of the two improves production efficiency and product quality, ensuring pure and fine flour suitable for subsequent processing.

The Vibro Sifter Flour plays an irreplaceable and important role in the flour processing process. It not only removes impurities from flour, ensuring its purity and quality, but also improves its fineness and uniformity through scientific screening and grading, thereby meeting the diverse needs of different customers and markets. Furthermore, the vibrating screen is easy to operate and maintain, energy-saving and environmentally friendly, and significantly improves production efficiency and product stability. When choosing a Vibro Sifter Flour machine, you can select it based on the mesh size requirements, output and equipment functions. At the same time, choosing equipment that can be used in combination can further improve efficiency.
