Creamer powder, after spray drying, typically has fine particles, low bulk density, and a tendency to generate static electricity. These characteristics create three major challenges during sieving:
First, electrostatic adhesion. The fine powder easily builds up static charge during sieving, causing particles to adhere to the screen surface and block the openings. Particles also attract each other, forming agglomerates that can be 10 to 100 times the size of a single particle, making them unable to pass through the mesh.
Second, friction and wedging. Increased friction between fine particles and the screen causes some particles to wedge into the apertures and become stuck. Once the screen is blocked, sieving efficiency drops sharply, leading to reduced throughput and unstable particle size control.
Third, frequent downtime for cleaning. Traditional vibrating screens often require manual shutdown and cleaning to resolve clogging – a labour‑intensive process that interrupts continuous production.
To address the clogging issue of creamer fine powders, Gaofu Machinery has integrated ultrasonic technology with conventional rotary vibrating screens, introducing the S49‑AC series Ultrasonic Vibration Sieve.
The core principle is straightforward: the system converts 220V, 50Hz electrical energy into high‑frequency electrical energy, which is fed into an ultrasonic transducer. This generates high‑frequency mechanical vibrations, superimposing low‑amplitude, high‑frequency ultrasonic motion on top of the traditional low‑frequency rotary vibration of the screen mesh.
This technology brings a fundamental change – the material on the screen receives both the low‑frequency rotary motion and the ultrasonic vibration, which effectively prevents mesh blockage while simultaneously improving throughput and product quality.
How does Gaofu's Ultrasonic Vibration Sieve solve the clogging problem?
Eliminates the root causes of clogging and boosts efficiency. The ultrasonic vibration waves applied to the screen mesh impart ultrasonic acceleration to the ultra‑fine powder, suppressing the factors that cause clogging – such as adhesion, friction, flat‑lying, and wedging. The material remains well‑dispersed on the screen surface and no longer tends to "clump" and block the openings.
Improves both sieving accuracy and output. With the ultrasonic system, sieving accuracy can be over 80% higher than conventional equipment, and throughput can be increased by 2 to 5 times. In terms of sieving passage rate, the addition of ultrasonic vibration typically increases the passing rate by 50% to 400% compared to screens without ultrasonic assistance. This means the same equipment, in the same operating time, produces significantly more qualified creamer product.
Reduces screen cleaning time and supports continuous production. The ultrasonic vibration sieve has a self‑cleaning effect, minimising or even eliminating the need for manual screen cleaning. Unlike conventional methods, it does not require bouncing balls or other auxiliary objects that could contaminate the powder. It also maintains mesh aperture size and ensures stable sieving accuracy. The equipment is well suited for large‑scale, uninterrupted production runs.
Lowers noise and improves the working environment. The ultrasonic design reduces powder contamination and wear that often occur with conventional sieving methods, and it noticeably reduces operating noise.
Meets food‑grade hygiene requirements. The Gaofu S49‑AC Ultrasonic Vibration Sieve can be manufactured with SUS304 stainless steel, making it suitable for food and pharmaceutical applications. The equipment has obtained multiple quality certifications, including ISO9001, CE, explosion‑proof certification, and GMP certification, meeting international standards and enabling exports to more than 100 countries and regions worldwide. Creamer producers can confidently use it in food‑grade production settings.
Gaofu's Ultrasonic Vibration Sieve is not limited to creamer; it is also widely used for sieving coffee powder, cocoa powder, seasonings, food additives, and Chinese and Western pharmaceutical raw materials. Whether dealing with highly adsorbent, easily agglomerating, sticky, highly electrostatic, or ultra‑fine powders, Gaofu's ultrasonic sieve offers effective solutions.
