Over 10,000+ customers' choice, Focus on screening industry 40+ years
Mustard powder is produced by grinding mature mustard seeds. Typical screening meshes range from 30 to 45 mesh, with throughputs generally between 300 and 700 kg/h. In large‑scale production, mustard powder screening faces several practical issues:
High throughput demands require continuous equipment operation. Modern seasoning production lines require a steady supply of raw materials. If the screening equipment stops due to blinding or breakdowns, the entire line is affected. Conventional screening equipment often struggles with mustard powder because fine particles tend to adhere to the screen, requiring frequent stoppages for cleaning – making continuous operation difficult to maintain.
Clear grading requirements. Different applications – mustard paste, mustard sauce, surface dusting for snacks, instant seasoning sachets – each have their own particle size specifications. The equipment must be capable of multi‑stage grading.
Strict workshop environment standards. Mustard powder is light and contains a high proportion of fines, which tend to become airborne during screening, affecting the workshop environment and causing material loss. Food manufacturers have clear cleanliness requirements for production areas, so the equipment must effectively control dust.
The linear vibrating screen addresses these three pain points directly: through a large screening area and stable linear motion for continuous high throughput; through multi‑deck configurations for one‑pass multi‑stage grading; and through a fully enclosed structure for effective dust control.
Gaofu's SZF series linear vibrating screen is driven by dual vibrating motors. When the two motors mounted longitudinally on the screen body operate in opposite directions, the lateral excitation forces cancel each other out, while the longitudinal forces are transmitted to the entire screen box, generating a linear vibration on the screen surface.
Under the combined action of excitation force and gravity, material is thrown up on the screen surface and moves forward in a straight line in a bouncing motion. Particles smaller than the screen openings pass through to the lower layer, while oversize material travels along the screen surface to the discharge outlet. Because the screening process is continuous and well‑organised, the machine can simultaneously produce several fractions of different particle sizes in a single pass.
Gaofu's SZF series linear vibrating screen supports continuous mustard powder screening through the following key features:
1. High processing capacity for large‑scale production
The rectangular screen surface provides a large effective screening area. Gaofu's SZF series offers various screen sizes, from 500×1600 mm to 1500×4000 mm. For example, the SZF‑1540 model has a screen width of 1500 mm and a length of 4000 mm. This large screening area provides the physical basis for high throughput, easily handling the several‑hundred‑kilograms‑per‑hour (or higher) requirements of mustard powder production lines.
2. Adjustable angle to suit mustard powder characteristics
Gaofu's linear vibrating screen features an adjustable excitation angle. The screen surface inclination can be adjusted within a range of 0° to 7° – a larger inclination increases the leap span and conveying speed, raising throughput per unit time; a smaller inclination prolongs material residence time on the screen, improving screening accuracy. This adjustability allows operators to fine‑tune the equipment settings based on the specific characteristics of the mustard powder and the desired throughput.
3. Multi‑deck configuration for simultaneous grading and impurity removal
The SZF series supports 1 to 5 screen decks, enabling a single machine to produce 2 to 6 different particle size fractions at once. For mustard powder processing, the upper deck intercepts fibre lumps and coarse impurities, while the lower decks achieve fine grading, maximising material utilisation. This "multi‑function in one machine" design reduces material transfer between multiple units, shortens overall processing time, and increases effective output per unit time.
4. Fully enclosed structure improves the workshop environment
The equipment features a fully enclosed design that prevents dust from escaping during operation. A negative‑pressure extraction system can be optionally added to further enhance dust control. For light, fine materials like mustard powder, this design not only improves the workshop environment but also reduces material loss.
5. Simple structure for easy maintenance
The linear vibrating screen has a relatively simple design with fewer moving parts, resulting in a low failure rate. The quick‑change screen structure simplifies screen replacement, significantly shortening maintenance downtime. For seasoning production lines that run 24/7, low failure rates and easy maintenance are key factors in maintaining overall line utilisation.
6. Food‑grade material construction
All parts that contact mustard powder can be made of 304 or 316L stainless steel, with smooth surfaces for easy cleaning. The screen mesh meets food‑grade safety standards, ensuring hygienic production. The overall equipment design complies with food industry regulations.
