High-Yield Starch Inline Vibratory Screen
Overview
Inline vibratory screen technology is widely used in high-capacity powder processing applications due to its efficient material flow and stable screening performance. A starch processing company in the United States required an inline vibratory screen solution to improve screening efficiency and reduce mesh blockage during continuous production.
Customer Requirements
- Material: Starch (fine powder, prone to agglomeration)
- Screening Accuracy: 100 mesh
- Capacity: Large throughput with continuous production
- Material of Construction: Full stainless steel structure (food-grade standard)
- Key Challenge: Prevent mesh blockage while improving capacity
- Site Limitation: Compact structure required due to limited installation space
Solution
Starch is lightweight, fine, and easily absorbs moisture, which can lead to agglomeration and mesh clogging. After analyzing the material characteristics and production conditions, our engineers recommended an Inline Vibratory Screen solution.
Compared with conventional round vibrating screens, inline vibratory screens are more suitable for large-capacity continuous screening applications. Their high-frequency vibration and direct discharge structure allow materials to pass through quickly, reducing material retention and improving overall screening efficiency.
After reviewing the proposal, the customer confirmed that the inline vibratory screen fully met the production requirements and proceeded with the solution.

FAQ
- Why is an Inline Vibratory Screen better suited for high-volume impurity removal than a standard rotary vibrating screen?
In traditional circular rotary vibrating screens, material moves across the screen mesh in a spiraling, outward-extending pattern, with the discharge outlet located on the side; this increases the material’s dwell time on the screen, making it ideal for precise classification. In contrast, the Inline Vibratory Screen features feed and discharge ports aligned along the same vertical axis. Powered by dual motors generating high-frequency vibrations, material is driven by gravity to fall directly and vertically through the screen mesh, passing through several times faster. Consequently, it holds a distinct advantage in efficiency for high-volume safety screening (check screening) applications. - How do you ensure that the screen does not clog when sifting fine powders—specifically at 100 mesh—that are highly susceptible to moisture absorption and clumping?
Our system utilizes dual vibrating motors to generate a powerful vertical excitation force, causing the powder particles to maintain a state of rapid, micro-bouncing motion across the screen mesh; this effectively disrupts the surface tension between the material’s molecules. For special materials with more stringent processing requirements or higher viscosity, we also offer a customizable Ultrasonic De-blinding System to ensure that the screen apertures remain 100% clear and unobstructed over the long term.
