Over 10,000+ customers' choice, Focus on screening industry 40+ years
During the processing and use of powdered sugar, manufacturers often face three persistent problems:
Challenge 1: Moisture absorption and lumping cause screen blinding. Powdered sugar is highly hygroscopic — it readily absorbs moisture from the air during storage and screening, forming hard lumps of varying sizes. Once these lumps enter the production line, they not only block the screen mesh but also cause formulation imbalances, affecting finished product quality.
Challenge 2: Electrostatic adhesion causes material retention. Powdered sugar tends to generate static electricity during high‑speed motion, causing powder to adhere to the screen, equipment walls, and piping. This not only wastes material but also adds the trouble of frequent stoppages for cleaning, severely impacting production efficiency.
Challenge 3: High fineness requirements make grading difficult. From coarse granulated sugar to ultra‑fine icing sugar, different applications require different fineness levels. The baking industry needs powdered sugar as fine as flour; the confectionery industry requires specific particle sizes for icing; and the beverage industry needs fine sugar that dissolves quickly. Achieving precise grading is a technical challenge.
To address the specific physical characteristics of powdered sugar, Gaofu Machinery's S49 series food‑grade powdered sugar rotary vibrating sieve incorporates multiple professional optimisations in design and functionality:
1. Food‑Grade Materials – Safeguarding Food Safety
All material‑contact parts are made of high‑quality 304 stainless steel — with polished surfaces, no dead corners, and easy cleaning — fully compliant with food‑grade hygiene standards. This fundamentally prevents heavy metal contamination, ensuring every grain of powdered sugar is pure and safe. All seals are made of food‑grade silicone , meeting the requirements of HACCP, GMP, and other food safety system certifications.
2. Multi‑Deck Grading – Multiple Specifications from One Machine
The equipment supports flexible configurations of 1 to 5 screen decks , enabling simultaneous separation of 2 to 6 grades. For cake and confectionery production lines:
Upper deck (impurity removal) : Removes fibre impurities, packaging debris, and large lumps from sugar powder
Middle decks (grading) : Separates sugar into coarse, medium, and fine grades by particle size
Lower deck (safety screen) : Ensures finished product purity, guaranteeing reliable sugar quality entering the packaging stage
3. Anti‑Blinding Screen Cleaning – Eliminating Blockage Problems
Bouncing ball cleaning system: Food‑grade silicone bouncing balls are installed below the screen — during operation, they continuously knock against the screen, automatically dislodging adhered sugar particles and keeping the screen fully permeable
Ultrasonic cleaning system (optional) : For ultra‑fine sugar above 200 mesh, an optional ultrasonic cleaning device can be added — using ultrasonic energy to break adhesion forces between particles, achieving efficient screening and truly solving electrostatic adhesion and fine powder blinding
4. Enclosed Structure – Moisture‑Proof and Dust‑Proof
The fully enclosed design effectively isolates external moisture, preventing secondary moisture absorption during screening. It also prevents dust emission, improving the workshop environment and reducing material loss. The fully enclosed negative‑pressure design achieves near‑zero dust emission during screening.
5. Quick Screen Changes – Adapting to Multi‑Product Production
Quick‑release clamps or flange connections allow tool‑free access — screen changes take only 3‑5 minutes. For production lines requiring frequent changes between different sugar specifications, this feature significantly reduces downtime.
6. High‑Precision Screening – Controllable Fineness
Screening fineness reaches up to 600 mesh (0.02 mm) , with filtration precision down to 5 microns. Impurities and oversize material are automatically discharged, supporting continuous operation. Screening accuracy reaches 99.56%.
Gaofu's food‑grade powdered sugar rotary vibrating sieve plays an indispensable role on cake, confectionery, and other production lines:
Cake and Bakery Production Lines:
Used for surface dusting and dough mixing — ensuring powdered sugar is fine and uniform, resulting in baked goods with beautiful colour and consistent texture. After removing lumps and impurities, sugar icing on cakes becomes more even and delicate, with improved appearance. Gaofu's series of rotary vibrating sieves features multi‑deck grading design — screen mesh can be customised according to raw material characteristics — effectively separating foreign matter, removing lumps, and ensuring fine, uniform ingredients.
Confectionery Production Lines:
Used for sugar coating and filling — ensuring icing is fine and smooth, with confectionery surfaces glossy and appealing. The fully enclosed structure prevents secondary contamination — complying with food production hygiene standards.
Beverage and Food Additive Production Lines:
Used for solid beverage blending — ensuring sugar dissolves quickly with no sediment residue. The equipment can be configured with multiple screen decks — completing coarse, medium, and fine grading in a single pass — ensuring uniform sugar particle size to meet different application requirements.
