Mustard powder screening mesh is not fixed – different product forms and application scenarios require different fineness levels:
Conventional screening (30‑45 mesh). Mustard powder typically requires 30‑45 mesh screening – this fineness range suits most mustard powder products, balancing flavour release and processing efficiency.
Fine screening (60 mesh and above). For premium mustard paste, instant seasoning sachets, and other products requiring fine texture, finer screening mesh is needed – ensuring the finished product has no grainy texture or residue.
Impurity removal screening (around 20 mesh). During raw material pre‑treatment, coarser mesh is needed to effectively intercept fibre lumps, foreign matter, and other impurities – ensuring smooth downstream operations.
Multi‑product changeover production. Seasoning producers typically handle multiple product varieties with different fineness requirements – equipment must have the ability to quickly adjust screening mesh.
Gaofu's S49 series mustard powder 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. This design allows mustard powder processors to complete the entire process from coarse impurity removal to fine grading on a single machine.
Typical 3‑deck screen configuration:
Upper deck (coarse screen, 20‑30 mesh) – impurity removal and lump interception. Plant fibre agglomerates, packaging debris, threads, and other foreign matter are effectively intercepted by the upper deck. For materials like mustard powder, which contains a certain proportion of plant fibre, the upper coarse screen is the first line of defence for smooth downstream screening.
Middle deck (grading screen, 30‑45 mesh) – achieving precise grading. This is the core level of mustard powder screening – separating qualified mustard powder from oversized and undersized particles, ensuring uniform particle size and consistent fineness. For producers who need to simultaneously produce multiple fineness specifications, the middle deck mesh can be flexibly changed according to order requirements.
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 core value of "one feed, multiple outputs":
Combined processes, reduced material transfer. In traditional modes, impurity removal and different mesh grading often require 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. This flexibility is particularly important for multi‑product, small‑batch seasoning producers.
High screening accuracy – eliminating size mixing and cross‑contamination. The precise multi‑deck grading ensures purity of each particle size grade – effectively eliminating size mixing and cross‑contamination. Gaofu's rotary vibrating sieve achieves screening accuracy of 99.56% , with screening fineness up to 600 mesh (0.02 mm) and filtration precision down to 5 microns.
Gaofu's S49 series mustard powder 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 mesh screening requirements.
The unique value of three‑dimensional vibration for multi‑deck screening:
Thorough material dispersion. The three‑dimensional compound motion causes material to be continuously tumbled, bounced, and spread outward in a spiral path – ensuring each screen deck receives thoroughly dispersed material, and the classification efficiency of each deck is maintained.
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 at different levels to find and pass through mesh openings.
High screen utilisation. Material is evenly distributed across each screen deck – avoiding local overloading or local idle areas – ensuring overall multi‑deck screening efficiency.
Mustard powder's agglomeration and static‑prone characteristics make blinding the most common challenge in multi‑deck screening – if one deck becomes blocked, the accuracy of the entire classification system is compromised. Gaofu's mustard powder 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 powder in a "suspended" state on the screen surface – fine particles cannot adhere to the screen, and blinding is effectively inhibited.
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 – significantly reducing changeover downtime.
Mustard powder is widely used in food processing and home cooking, placing high hygiene demands on production equipment. Gaofu's mustard powder rotary 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 equipment features a fully enclosed structure with food‑grade seals – preventing dust emission during operation. For light, fine materials like mustard powder, this design improves the workshop environment and reduces material loss.
