The electrostatic blinding problem in creamer screening stems from the unique material characteristics of creamer combined with physical effects during screening.
Fat content exacerbates adhesion. Creamer contains vegetable fat. During screening, friction between fine particles and the screen generates heat – the fat forms a thin, sticky film on the screen surface. Fine powder is "glued" to the mesh by this film, accumulating thicker and thicker.
Electrostatic attraction is the primary driver of blinding. Creamer particles are very fine – during screening, friction between particles readily generates static electricity. Charged fine particles attract each other to form agglomerates while adhering firmly to the screen surface. Conventional screens processing creamer often suffer from "blinding shortly after starting."
The combination of fat adhesion and electrostatic attraction makes creamer significantly more difficult to screen than ordinary powdered materials. The traditional approach of "clean after blinding, then blind again" treats the symptoms rather than the root cause – fundamentally failing to solve the problem.
Gaofu's S49‑AC series creamer ultrasonic vibrating sieve is a high‑precision screening machine developed by innovatively integrating ultrasonic screening technology with the conventional rotary vibrating sieve. Its working principle can be summarised in three key steps:
Conversion of electrical energy to high‑frequency mechanical energy. The equipment converts 220V, 50Hz electrical energy into high‑frequency electrical energy – the ultrasonic transducer then converts this into high‑frequency mechanical vibration. A low‑amplitude, high‑frequency ultrasonic vibration wave (mechanical wave) is superimposed on the screen surface.
High‑frequency micro‑vibration breaks electrostatic adhesion. High‑frequency, low‑amplitude vibration is transmitted to every wire of the screen mesh – subjecting ultra‑fine powder particles to significant ultrasonic acceleration – keeping material on the screen surface in a continuously suspended state – thereby inhibiting adhesion, friction, settling, and wedging – the main causes of blinding. This high‑frequency vibration effectively breaks molecular adhesion and electrostatic forces between particles – instantly disrupting electrostatic attraction and agglomeration.
Continuous blinding prevention – maintaining screen permeability. Ultrasonic vibration keeps fine powder in a "suspended" state on the screen surface – preventing adhesion to the screen. Without using contact‑based cleaning devices such as bouncing balls or brush systems, the screen remains fully permeable throughout long‑duration continuous operation. It effectively solves blinding problems caused by electrostatic adhesion on the mesh and powder agglomeration.
In simple terms: a conventional screen is like a congested road where fine particles are "stuck" to the surface by static electricity; an ultrasonic vibrating screen is like adding continuous micro‑vibration to the road – keeping material in constant motion and preventing accumulation.
1. Fundamentally solves the electrostatic blinding problem
Conventional rotary vibrating sieves rely on low‑frequency vibration to make material bounce on the screen surface. For ultra‑fine, static‑prone, easily agglomerated powders like creamer, fine particles quickly block the mesh under electrostatic attraction. Gaofu's S49‑AC ultrasonic vibrating sieve superimposes high‑frequency ultrasonic mechanical waves onto the conventional rotary vibrating sieve – keeping fine powder continuously dispersed and suspended – preventing accumulation on the screen surface. It effectively solves the screening challenges of highly adsorbable, easily agglomerated, static‑prone, and ultra‑fine materials.
2. Simultaneous improvement in screening accuracy and throughput
The ultrasonic vibrating sieve changes the contamination and wear caused by conventional screening methods on powders – screening accuracy can be improved by 1% to 70%, and throughput increased by 0.5 to 10 times. For high‑value food ingredients like creamer, accuracy improvement directly relates to product quality consistency, while throughput increase means greater production capacity.
3. Reduces or eliminates screen cleaning time
The self‑cleaning function of the ultrasonic system keeps the screen fully permeable during operation. Operators do not need to stop frequently to clean the screen – the equipment can run continuously for extended periods, significantly reducing manual intervention and downtime.
4. Breaks down adhered material – reduces oversize material
The high‑frequency micro‑vibration of ultrasonic technology effectively breaks down material adhering to the screen surface – reducing the proportion of oversize material. For fat‑containing materials like creamer, this means higher material passage rates and less raw material waste.
5. Food‑grade stainless steel construction – safeguarding food safety
Gaofu's S49‑AC ultrasonic vibrating sieve uses 304 food‑grade stainless steel for all material‑contact parts (316L available on request), with finely polished surfaces and no dead corners. The fully enclosed structure effectively prevents dust emission, avoids material cross‑contamination, and complies with food industry GMP standards.
6. Adapts to multiple fineness requirements
Gaofu's S49‑AC series ultrasonic vibrating sieve covers screen mesh from 2 to 500 mesh – effectively screening ultra‑fine powders. Whether for conventional creamer screening or premium applications with higher fineness requirements – suitable screen configurations are available.
| Comparison Dimension | Conventional Rotary Vibrating Sieve | Ultrasonic Vibrating Sieve |
| Blinding | Blinds shortly after operation – frequent stoppages for cleaning | High‑frequency vibration keeps powder suspended – screen remains permeable |
| Electrostatic adhesion | Fine powder adheres to screen due to static – worsening blinding | High‑frequency vibration breaks electrostatic adhesion – fine powder remains dispersed |
| Screening accuracy | Fluctuates with blinding – inconsistent batch quality | Accuracy can be improved by 1% to 70% |
| Throughput | Capacity constrained – frequent stoppages reduce output | Throughput can be increased by 0.5 to 10 times |
Manual intervention | Requires frequent manual screen cleaning | Self‑cleaning function – minimal intervention required |
