Over 10,000+ customers' choice, Focus on screening industry 40+ years
In actual seasoning production, the screening stage faces the following practical challenges:
Lumps cause uneven mixing. Powdered seasonings tend to absorb moisture and form lumps. Traditional screening often fails to break these lumps effectively, leading to uneven mixing and directly affecting the consistency of the final product.
Fine impurities are difficult to remove, compromising purity. Microscopic foreign matter, packaging debris, dust, and other impurities in raw materials are hard to eliminate completely. These not only affect product appearance but also pose potential food safety risks.
Fine powders easily blind the screen, reducing efficiency. Spices contain a high proportion of fine particles, which tend to block the screen mesh during screening, causing frequent stoppages and severely impacting production efficiency.
Gaofu's S49 series rotary vibrating sieve uses a vertical vibration motor as the excitation source. Eccentric weights mounted 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. The material moves on the screen in a spiral outward trajectory, ensuring both high screening accuracy and considerable throughput.
Addressing the three major pain points of seasoning screening, Gaofu's rotary vibrating sieve offers systematic solutions:
1. Efficient impurity removal + lump breaking for improved cleanliness
The equipment is equipped with food‑grade screens and flexible lump‑breaking devices. It effectively removes dust, impurities, and foreign matter from seasonings, while gently breaking up agglomerated compound seasonings without damaging the particles. The result is clean, free‑flowing screened seasonings with reduced material loss and improved raw material utilisation. The built‑in flexible breaking device softly resolves lumps during screening, avoiding excessive breakage of brittle materials – enhancing screening efficiency while better preserving the original characteristics of the product.
2. Overcoming screen blinding for continuous production
Gaofu's seasoning rotary vibrating sieve incorporates several optimisations to address screen blinding:
Efficient screen cleaning systems: Configurable with bouncing‑ball cleaning systems or ultrasonic systems that continuously act on the screen during operation, effectively preventing fine particle adhesion and blinding, and maintaining screen permeability.
Anti‑blinding structural design: The screen tensioning structure ensures a flat screen surface, minimising material accumulation dead zones and reducing the likelihood of blinding from the design perspective.
3. Precise grading ensures uniform seasoning fineness
The equipment features adjustable vibration frequency and amplitude, allowing flexible parameter adjustments according to different seasoning types – such as single spices (e.g., Sichuan pepper, star anise, cinnamon), compound seasonings (e.g., hotpot base powder, barbecue seasoning), and powdered seasonings (e.g., pepper powder, cumin powder). It supports 1 to 5 screen decks, enabling simultaneous impurity removal, lump breaking, and multi‑stage grading in a single pass, ensuring uniform particle size and consistent fineness.
4. Food‑grade standards safeguard food safety
Seasonings are widely used in food processing and home cooking, placing extremely high hygiene demands on production equipment. Gaofu's seasoning rotary vibrating sieve fully considers food safety requirements in both material selection and structural design:
High‑quality stainless steel: All parts that contact the product are standardly made of 304 stainless steel (316L available on request), with finely polished surfaces meeting sanitary requirements;
Fully enclosed structure: The totally enclosed design effectively prevents dust emission during screening, avoids cross‑contamination, and improves the workshop environment;
No‑dead‑corner design: The simple structure allows quick disassembly and cleaning, meeting food‑grade production hygiene requirements and reducing cross‑contamination between batches.
5. Stable operation for large‑scale production
The reinforced frame design provides strong load capacity and supports long‑duration continuous operation. Optimised vibration damping results in low noise and reasonable energy consumption, helping reduce long‑term operating costs. The equipment is suitable for continuous seasoning production lines – it can operate as a standalone unit or be integrated into existing seasoning processing lines.
