In the food and health supplement industries, the quality and consistency of powder-based ingredients such as lotus root powder are vital for both product performance and consumer trust. Known for its health benefits and high fiber content, lotus root powder is a popular ingredient in nutritional products and traditional remedies. However, due to its ultra-lightweight texture and fibrous structure, sieving lotus root powder can pose significant challenges when using conventional screening equipment.
To address these challenges, the Airflow vibrating screen offers a highly effective and specialized sieving solution designed for ultra-fine, light, and fibrous powders.
Sieving Purpose: Impurity Removal at 100 Mesh
The primary goal of sieving lotus root powder is removing impurities — such as foreign particles, oversize agglomerates, and residual fibrous fragments — to ensure a smooth, clean, and consistent powder. A 100 mesh screen (approximately 150 microns) is typically used to achieve this level of filtration, allowing only particles of the desired size to pass through while retaining any contaminants or clumps.
Why Choose an Airflow Vibrating Screen?
Traditional vibrating screens often struggle with materials like lotus root powder due to their tendency to form agglomerates, high fiber content, and low bulk density. The airflow vibrating screen, also known as a centrifugal sifter, uses a different approach that is ideally suited for such characteristics.
1. Optimized for Ultra-Light, Fibrous Powders
Unlike conventional flat vibrating sieves, the airflow screen employs a cylindrical screen mesh combined with high-speed air-driven vibration and centrifugal force. This unique design allows the equipment to process light, fibrous powders without clogging or sticking. The gentle airflow helps carry particles through the mesh, preventing buildup and ensuring a steady flow of material.
This makes the airflow vibrating screen an ideal choice for lotus root powder, which is both airy and high in fiber.
2. Deagglomeration of Pseudo-Caked Materials
One of the key features of the airflow vibrating screen is its ability to break apart pseudo-agglomerated materials — those that appear caked or clumped together during storage or transport but are not permanently bonded. The internal rotating blades within the sifter apply mild mechanical force to re-agitate and deagglomerate the material, helping recover usable powder that might otherwise be discarded.
For lotus root powder, which can often clump due to its natural starch content and moisture absorption, this is a major operational advantage.
3. Real-World Performance Testing Available
To help clients make confident decisions, many manufacturers offer on-site testing services, allowing prospective buyers to bring their own materials (such as lotus root powder) to test on actual equipment. This enables a clear understanding of how the airflow screen performs under real conditions, showcasing the actual sieving efficiency, capacity, and output quality.
For businesses that are cautious about investment or wish to verify claims, this test-before-you-buy option provides valuable peace of mind.
