The physical characteristics of mustard powder present three major challenges during screening:
Easy agglomeration: Mustard contains a certain proportion of plant fibre – after grinding, these fibres exist as fine particles in the powder, easily intertwining to form agglomerates. The fibrous components cause powder adhesion and lumping, increasing particle size and reducing screening efficiency.
Easy screen blinding: Mustard powder has strong adsorbability and tends to generate static electricity. During screening, friction between particles readily produces static charges – powder adheres to the screen surface and blocks the mesh. Ordinary screens can become "clogged" almost instantly, making frequent stoppages for cleaning the norm.
Low bulk density: Mustard powder particles are fine, light, and easily suspended – on conventional screening equipment, they struggle to pass through high‑mesh screens by gravity alone, often failing to meet design expectations for screening accuracy and throughput.
These three challenges intertwine, making conventional screening equipment struggle with mustard powder. Conventional rotary vibrating screens typically achieve throughput of only around 50 kg/h when processing mustard powder. 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 mustard powder ultrasonic vibrating sieve is a high‑precision screening machine developed by innovatively integrating ultrasonic screening technology with the classic S49 series three‑dimensional rotary vibrating sieve. Its working principle can be summarised in three steps:
Conversion of electrical energy to high‑frequency mechanical energy: The equipment converts 220V, 50Hz electrical energy into 36 kHz high‑frequency electrical energy – the ultrasonic transducer then converts this into 36 kHz mechanical vibration. Material on the screen undergoes low‑frequency rotary vibration combined with superimposed high‑frequency ultrasonic vibration.
High‑frequency micro‑vibration breaks adhesion: The 36 kHz high‑frequency, low‑amplitude vibration is transmitted to every wire of the screen mesh – subjecting ultra‑fine powder particles to significant ultrasonic acceleration – inhibiting adhesion, friction, settling, and wedging – the main causes of blinding. This tens‑of‑thousands‑of‑cycles‑per‑second high‑frequency micro‑vibration prevents fine particles from finding a stable position to wedge into the mesh openings, while simultaneously breaking apart agglomerated particles the moment they contact the screen surface.
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 continuous operation lasting dozens of hours.
In simple terms: a conventional screen is like a congested road where fine particles easily get stuck at intersections; an ultrasonic vibrating screen is like adding continuous traffic control – allowing material to pass through much more smoothly.
1. Fundamentally solves the 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 mustard powder, fine particles quickly block the mesh. Gaofu's S49‑AC ultrasonic vibrating sieve superimposes high‑frequency ultrasonic mechanical waves onto the conventional rotary vibrating sieve. High‑frequency vibration keeps fine powder continuously dispersed – preventing accumulation on the screen surface. Screen permeability is consistently maintained at high levels, effectively solving the blinding problem.
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 over 80%, and throughput increased by 2 to 5 times. For mustard powder processing, conventional rotary vibrating screens achieve around 50 kg/h, while ultrasonic vibrating sieves can achieve over 100 kg/h. For high‑value seasoning materials like mustard powder, accuracy improvement directly relates to product quality consistency, while throughput increase means greater production capacity.
3. Solves electrostatic adhesion and agglomeration problems
The fibres in mustard powder generate static electricity through friction during screening, causing agglomeration. The high‑frequency micro‑vibration of ultrasonic technology 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. Without altering the material properties of mustard powder, screening accuracy can be effectively improved.
4. Self‑cleaning function – no additional cleaning devices required
The ultrasonic vibrating sieve features a powerful self‑cleaning function – fine powder no longer adheres to the mesh, eliminating the need for manual screen cleaning. Operators do not need to stop frequently to clean the screen – the equipment can run continuously for extended periods. User feedback confirms that the ultrasonic vibrating sieve eliminates the need for frequent stoppages for screen cleaning, saving operators time and effort.
5. Food‑grade stainless steel construction – safeguarding food safety
Mustard powder is widely used in food processing and home cooking, placing high hygiene demands on production equipment. 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 improves the workshop environment – complying 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. Mustard powder typically requires 30‑45 mesh screening, with throughput of 500‑700 kg/h. The ultrasonic vibrating sieve can effectively screen ultra‑fine powders above 400 mesh. Whether for conventional mustard powder impurity removal screening or high‑fineness products such as premium mustard paste and instant seasoning sachets – suitable screen configurations are available.
