Conventional screening equipment typically has side‑mounted discharge outlets – material must travel a long path across the screen surface before discharge. In high‑volume production, this design can cause material accumulation – discharge speed cannot keep up with feed rate, screen surface load increases, eventually leading to blinding and stoppage.
Gaofu's double motor direct discharge vibrating screen takes a completely different approach – the inlet and outlet are aligned in the same vertical direction. Material enters from the top feed port, and on‑spec material falls vertically into the lower hopper or next process, while impurities are automatically discharged from the side reject outlet.
The practical value of "straight‑in, straight‑out" design:
Fast discharge speed. Material residence time on the screen surface is minimised – on‑spec material is discharged directly from the bottom after passing through the screen, without detouring to side outlets. For the same specification, the direct discharge screen achieves throughput of 10‑15 tonnes/hour – 40%‑60% higher than conventional vibrating screens. Output is 2‑5 times that of ordinary circular screens.
Reduced blinding. Material passes through quickly without滞留 or accumulation on the screen surface – structurally lowering the probability of blinding. The equipment can run continuously without frequent stoppages for cleaning.
Easy line integration. The direct discharge screen has a flat, compact design with a low profile – easy to flexibly install in space‑constrained workshops. The large‑volume discharge outlet is at the bottom – particularly suitable for direct integration into production lines or pairing with packaging machines.
Direct discharge screens are available in single‑motor and dual‑motor types. A single‑motor unit primarily generates vertical vibration on the material and does not have automatic discharge capability. A dual‑motor unit generates a vortex motion on the screen surface with automatic discharge capability – ideal for impurity removal and screening in powder production lines.
Gaofu's double motor spice direct discharge vibrating screen features two vibration motors of the same model symmetrically mounted on both sides of the screen machine, with eccentric weights installed at the top and bottom of the motor shafts. The two motors work in coordination, generating a three‑dimensional compound motion (horizontal, vertical, and inclined) – providing stronger excitation force than a single motor, with more thorough three‑dimensional rotational motion on the screen surface.
The unique advantages of dual‑motor design in spice processing:
Throughput increased by over 50%. The dual‑motor design delivers greater excitation force, suitable for high‑flow conditions. For spice processors, this means a single machine matches the capacity rhythm of the entire production line.
Thoroughly disperses lumpy materials. Spice powders tend to absorb moisture and form lumps during storage. Conventional screening equipment often jams when processing lumpy materials. The three‑dimensional rotational motion generated by the dual‑motor design thoroughly disperses material – lumps are effectively broken for rapid passage. It delivers excellent screening performance for lumpy and sticky materials.
Automatic discharge for continuous operation. The dual‑motor design generates vortex motion on the screen surface with automatic discharge capability. Impurities and foreign matter are separated and automatically moved to the reject outlet –合格 material flows continuously from the bottom straight‑through outlet. The equipment supports 24‑hour continuous production without frequent manual intervention.
Spices are widely used in food processing and home cooking, placing strict hygiene demands on production equipment. All material‑contact parts of Gaofu's double motor spice direct discharge vibrating screen are made of 304 stainless steel , complying with food hygiene standards.
The core assurance of stainless steel construction:
Safe and contamination‑free. 304 stainless steel complies with food contact metal material standards – ensuring a pure, contamination‑free screening process with no heavy metal contamination.
Easy to clean – no dead corners. The equipment is easy to clean internally and externally with no dead corners – meeting food and pharmaceutical industry standards. It is easy to disassemble for rapid cleaning and sanitisation – meeting food‑grade GMP requirements.
Corrosion‑resistant and durable. Stainless steel is corrosion‑resistant, high‑temperature‑resistant, and rust‑proof – capable of withstanding long‑term contact with salt and acidic components in spices – with a long service life.
Spice powders are fine and lightweight – during screening, they readily generate dust. Gaofu's double motor spice direct discharge vibrating screen features a fully enclosed structure with dust‑proof seals – no dust emission during operation.
The value of sealed dust‑proof design:
Reduced material loss. No dust emission means no material spillage – every gram of spice powder is effectively collected.
Improved workshop environment. Dust concentration in workshop air is reduced – walls and equipment surfaces no longer accumulate powder frequently, cleaning cycles are significantly extended, and operator working conditions are improved.
Controllable operating noise. Equipment operating noise is kept around 70 decibels – complying with factory occupational health management requirements.
Seasoning producers typically handle multiple product varieties – Sichuan pepper powder, cumin powder, chilli powder, five‑spice powder, and more – and screen change efficiency directly affects production rhythm.
Gaofu's double motor spice direct discharge vibrating screen features a quick‑release screen structure – screen changes are simple and quick, taking only 3‑5 minutes. For producers who frequently switch between different spice varieties, this capability significantly reduces changeover downtime and improves equipment utilisation.
Gaofu's double motor spice direct discharge vibrating screen is used in the following typical spice processing applications:
Impurity removal and screening of powdered spices: Breaking lumps and separating impurities from Sichuan pepper powder, cumin powder, chilli powder, five‑spice powder, and other powdered seasonings
Impurity removal of whole spices: Rapid removal of stones, twine, and other foreign matter from Sichuan pepper, cumin, pepper, chilli, and other whole spices
Online impurity removal on seasoning production lines: Directly integrated into production lines for rapid impurity removal before feeding or grinding
Integration with packaging machines: Material is screened and then directly fed into packaging machines – achieving integrated "screening + packaging" operation
