Creamer powder contains vegetable fat, has high fineness, and low bulk density – in conventional screening operations, these characteristics create three particularly troublesome problems:
First, fat adhesion causes frequent blinding. The fat in creamer generates heat through friction during screening, forming a thin, sticky film on the screen surface. Fine powder is "glued" to the mesh by this film, accumulating thicker and thicker until the openings are completely sealed. Conventional screening equipment processing creamer often suffers from blinding shortly after operation begins – forcing frequent stoppages for cleaning.
Second, electrostatic attraction worsens 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. The combination of fat adhesion and electrostatic attraction makes creamer significantly more difficult to screen than ordinary powdered materials.
Third, the high‑fat nature demands higher equipment cleanliness. The fat in creamer not only adheres to the screen but also coats equipment walls and piping – increasing cleaning difficulty. During multi‑product changeover production, if cleaning is incomplete, residual creamer may contaminate the next batch – causing cross‑contamination.
These three challenges intertwine, making conventional screening equipment struggle with creamer. The traditional approach of "clean after blinding, then blind again" treats the symptoms rather than the root cause – reducing throughput, increasing labour costs, and causing material loss.
With over 40 years of experience in screening, Gaofu Machinery has developed the S49‑AC series food‑grade ultrasonic vibrating sieve specifically for the purification screening needs of creamer and other high‑fat, ultra‑fine powders. This equipment innovatively integrates ultrasonic screening technology with the classic three‑dimensional rotary vibrating sieve – specifically designed to solve the screening challenges of highly adsorbable, easily agglomerated, static‑prone, and ultra‑fine materials.
The working principle of the ultrasonic vibrating sieve can be summarised as:
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 is superimposed on the screen surface – subjecting ultra‑fine powder particles to significant ultrasonic acceleration – keeping material on the screen surface in a continuously suspended state.
While the material undergoes conventional three‑dimensional tumbling and spreading motion, it is continuously subjected to acoustic shear forces – rapidly breaking the agglomerated structure of powder particles and eliminating electrostatic adhesion forces. This allows ultra‑fine powder particles to penetrate the mesh uniformly as individual particles – fundamentally solving the problems of fine powder adhesion, blinding, material drifting, and uneven screening.
High‑frequency micro‑vibration effectively breaks molecular adhesion and electrostatic forces between particles – instantly disrupting electrostatic attraction and agglomeration. Agglomerates are broken apart the moment they contact the screen surface – fine particles remain dispersed and pass through the screen smoothly. The ultrasonic system features a built‑in self‑cleaning function – without using contact‑based cleaning devices such as bouncing balls or brush systems – the screen remains fully permeable throughout long‑duration continuous operation.
In simple terms: a conventional screen processing creamer is like a "congested road" – fine particles are "stuck" to the surface by fat adhesion and static electricity; an ultrasonic vibrating sieve is like adding continuous micro‑vibration to the road – keeping material in constant motion and preventing accumulation.
Compared with conventional rotary vibrating screens, the ultrasonic vibrating sieve offers significant advantages in solving powder agglomeration and adhesion:
Inhibits adhesion: High‑frequency ultrasonic vibration prevents material from clinging to the screen – particularly effective for static‑prone powders
Breaks agglomeration: Ultrasonic vibration effectively breaks down adhered material, reducing oversize material – generally increasing passage rate by 5 to 20 times compared with vibrating screens without ultrasonic technology
Continuous blinding prevention: High‑frequency micro‑vibration keeps fine powder in a "suspended" state – preventing adhesion to the screen – with screen permeability consistently maintained at high levels
Gaofu's creamer ultrasonic vibrating sieve "flexible screening" solution is not the application of a single technology – it is a systematic engineering achievement encompassing vibration principles, cleaning methods, screen structure, and overall machine design.
1. High‑frequency micro‑vibration + three‑dimensional rotary vibration – dual forces breaking agglomeration
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 the combined effects of electrostatic attraction and fat adhesion. Gaofu's S49‑AC ultrasonic vibrating sieve superimposes high‑frequency ultrasonic mechanical waves onto the conventional three‑dimensional rotary vibration. The three‑dimensional rotary vibration thoroughly disperses material in a spiral path, while the high‑frequency ultrasonic micro‑vibration continuously disrupts electrostatic adhesion and agglomeration between particles. Working in synergy, these forces keep fine powder continuously dispersed and suspended – preventing accumulation on the screen surface.
2. Ultrasonic self‑cleaning – no contact‑based cleaning components required
Conventional rotary vibrating sieves rely on contact‑based components such as bouncing balls for screen cleaning. However, as bouncing balls strike the screen, wear particles from the balls themselves may contaminate the material – causing secondary contamination. Gaofu's ultrasonic vibrating sieve achieves self‑cleaning through high‑frequency vibration – without contact‑based components such as bouncing balls or brush systems. The built‑in adaptive digital controller continuously monitors the amount of material on the screen and automatically adjusts the ultrasonic output frequency and power – maintaining consistent anti‑blinding performance even under fluctuating feed rates.
3. Food‑grade stainless steel construction – eliminating secondary contamination
Creamer is widely used in coffee, milk tea, bakery, and other food applications – placing extremely strict hygiene standards on production equipment. Gaofu's S49‑AC series ultrasonic vibrating sieve uses food‑grade 304 stainless steel for all material‑contact parts (316L available on request), with finely polished surfaces and no dead corners – leaving no room for bacterial growth. The equipment features a fully enclosed structure – powder does not disperse, liquids do not leak – effectively preventing dust emission and material cross‑contamination during screening. The entire machine design complies with GMP standards – providing reliable food safety assurance at the equipment level.
4. Multi‑deck grading – multiple specifications from one feed
The equipment supports flexible configurations of 1 to 5 screen decks , enabling a single machine to simultaneously complete 2 to 6 grades of separation or filtration. For creamer processing, the upper deck intercepts lumps and foreign matter, the middle decks achieve fine grading, and the lower deck acts as a safety screen to ensure finished product purity – one feed completes multiple steps – reducing material transfers between machines and cross‑contamination risks.
In actual creamer screening operations, Gaofu's ultrasonic vibrating sieve flexible screening solution delivers tangible improvements:
Significantly improved screening accuracy. 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%. For high‑value food ingredients like creamer, accuracy improvement directly relates to product quality consistency – finer particle size distribution, more thorough impurity removal, and more reliable finished product purity.
Notably increased throughput. By eliminating the blinding problem, the equipment can operate continuously – throughput is 2 to 10 times that of conventional screens. 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.
Significantly improved passage rate. The ultrasonic vibrating sieve breaks down adhered material, reducing oversize material – generally increasing passage rate by 5 to 20 times compared with vibrating screens without ultrasonic technology. For fat‑containing, adhesion‑prone materials like creamer, this means higher material passage rates and less raw material waste.
Extended screen service life. Since fine powder cannot adhere to the screen, the screen remains fully permeable – reducing wear and damage from blinding. Screen replacement frequency is reduced, and maintenance costs decrease accordingly.
24‑hour continuous stable operation. The ultrasonic self‑cleaning system ensures long‑duration continuous stable operation. For creamer production lines requiring 24‑hour continuous operation, this means higher equipment utilisation and more stable output.
Wide screen mesh coverage. Gaofu's S49‑AC series ultrasonic vibrating sieve covers screen mesh from 2 to 500 mesh. Whether for conventional creamer screening (80‑120 mesh) or premium applications with higher fineness requirements – suitable screen configurations are available.
