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 when screening mustard powder, leading to frequent stoppages for cleaning.
Low bulk density. Mustard powder particles settle slowly with unstable movement trajectories – on conventional screening equipment, they struggle to pass through high‑mesh screens by gravity alone, affecting screening accuracy.
These three challenges intertwine, making conventional screening equipment struggle with mustard powder – frequent stoppages for screen cleaning become the norm, grading accuracy becomes difficult to maintain, and throughput remains hard to improve.
Gaofu's S49 series rotary vibrating sieve (three‑dimensional rotary vibrating sieve) uses a vertical vibration motor as the excitation source. Eccentric weights installed at the top and bottom of the motor convert rotary motion into a three‑dimensional compound motion (horizontal, vertical, and inclined), which is transmitted to the screen surface. Material moves on the screen surface in an outward involute spiral path – spreading from the centre toward the periphery.
By adjusting the phase angle of the upper and lower eccentric weights, the material's movement trajectory and residence time on the screen can be flexibly changed to suit different materials such as mustard powder.
The core value of three‑dimensional vibration for mustard powder grading:
Thorough material dispersion. The three‑dimensional compound motion causes material to be continuously tumbled, bounced, and spread outward in a spiral path – fibre agglomerates in the mustard powder are naturally loosened during motion, and individual particles have ample opportunity to contact the screen surface.
Long screening path. The spiral motion trajectory from the centre to the edge allows material to travel a relatively long path across a relatively small screening area – giving fines sufficient time to find and pass through mesh openings.
High screen utilisation. Material is evenly distributed across the screen surface – avoiding local overloading or local idle areas – ensuring screening efficiency.
Gaofu's S49 series rotary vibrating sieve supports flexible configurations of 1 to 5 screen decks , enabling 2 to 6 grades of separation or filtration simultaneously in a single feed. Screening fineness can reach up to 600 mesh (0.02 mm) , with filtration precision down to 5 microns.
For mustard powder processing, the multi‑deck screen configuration is as follows:
Upper deck (coarse screen) – intercepting fibre lumps and foreign matter. Plant fibre agglomerates, packaging debris, and other foreign matter in mustard powder are effectively intercepted by the upper deck – protecting material purity at the source.
Middle deck (grading screen, 30‑45 mesh) – achieving precise grading. Mustard powder typically requires 30‑45 mesh screening, with throughput of 300‑700 kg/h. The middle deck separates合格 mustard powder from oversized and undersized particles – ensuring uniform particle size and consistent fineness.
Lower deck (safety screen) – ensuring finished product purity. As the final checkpoint, it further intercepts fine impurities, ensuring reliable purity of mustard powder entering the packaging stage.
The value of "one feed, multiple outputs" design:
Combined processes, reduced material transfer. In traditional modes, different mesh grading often requires multiple machines or multiple screening passes – material transfer between machines increases contamination risk. Gaofu's rotary vibrating sieve combines multiple processes into a single machine – reducing material exposure and cross‑contamination opportunities.
One machine, multiple functions – flexible adaptation to different needs. When switching between different fineness specifications, simply change the corresponding screen deck – no need to replace the entire machine.
High classification efficiency. Gaofu's rotary vibrating sieve achieves screening accuracy of 99.56%. The precise multi‑deck grading ensures purity of each particle size grade – effectively eliminating size mixing and cross‑contamination.
The most common challenge in mustard powder screening is screen blinding – fine particles blocking the mesh cause screening efficiency to drop, and grading accuracy fluctuates accordingly. Gaofu's rotary vibrating sieve provides solutions across multiple levels:
Bouncing ball cleaning system. Bouncing balls installed below the screen continuously strike the screen surface through vibration – dislodging fine powder adhering to the screen and particles wedged in the mesh – achieving real‑time "screening‑while‑cleaning" anti‑blinding.
Ultrasonic cleaning system (optional). For ultra‑fine powders like mustard powder – which are static‑prone and easily agglomerated – an ultrasonic cleaning system can be optionally added. High‑frequency ultrasonic vibration keeps material in a suspended state on the screen surface – inhibiting adhesion, friction, settling, and wedging – the main causes of blinding. The problem of ordinary screens becoming instantly clogged is fundamentally solved. Screening accuracy can be improved by 1% to 70% , and throughput can be increased by 0.5 to 10 times.
Separate mother‑screen / fine‑screen design. Gaofu's rotary vibrating sieve features a unique mother‑screen and fine‑screen separation design – the mother screen fully supports the working fine screen, which does not directly bear the impact of the material. This design not only extends screen service life but also allows screen changes in just 3‑5 minutes.
Fully enclosed structure. The equipment features a fully enclosed design – powder does not disperse, and impurities and oversize material are automatically discharged, supporting continuous operation. For light, fine materials like mustard powder, this design improves the workshop environment and reduces material loss.
Mustard powder is widely used in food processing and home cooking, placing high hygiene demands on production equipment. Gaofu's rotary vibrating sieve uses 304 food‑grade stainless steel for all material‑contact parts (316L available on request), with finely polished surfaces meeting sanitary requirements.
The simple structure has no dead corners , supports quick disassembly and cleaning, meets food‑grade production hygiene requirements, and reduces cross‑contamination between batches.
In actual mustard powder grading screening, Gaofu's rotary vibrating sieve delivers tangible improvements in several areas:
Grading accuracy is assured. Through precise multi‑deck screen configurations, mustard powder is accurately separated into different particle size grades – ensuring consistent fineness and uniform particle size.
Production efficiency is significantly improved. The three‑dimensional vibration trajectory and automatic impurity discharge reduce stoppages caused by blinding; quick screen change capability (3‑5 minutes) shortens changeover downtime.
Product purity is enhanced. By effectively removing fibre lumps and foreign matter from mustard powder, finished product purity is ensured.
Workshop environment is improved. The fully enclosed structure effectively controls dust emission, improving the workshop environment.
