Coconut flakes are granular or fibrous, with a light, fluffy texture and a fat content of approximately 40% to 60%. This unique material characteristic presents three major screening challenges:
High‑fat adhesion – frequent blinding. The fat in coconut flakes forms a sticky film on the screen surface during screening, causing fines to become "glued" to the mesh. Combined with plant fibres that tend to wrap around the screen wires forming "fibre bridges," screen blinding becomes a constant problem.
Moisture absorption and lumping – affecting grading accuracy. Coconut flakes have a certain degree of hygroscopicity – they readily absorb moisture from the air during storage or conveying, forming hard lumps. These lumps become wedged in the mesh openings, further worsening blinding and affecting grading accuracy.
High fines content – dust emission. Coconut flakes generate large quantities of fines during processing – these are lightweight and easily airborne. On traditional open screening equipment, they readily escape through equipment gaps into the workshop air – causing material loss and polluting the production environment.
The core advantage of Gaofu's S49 series coconut flakes rotary vibrating sieve lies in its flexible multi‑deck screen configuration capability. The equipment supports 1 to 5 screen decks , enabling a single machine to simultaneously complete 2 to 6 grades of separation or filtration. The coconut flakes screening mesh range covers 8‑120 mesh , with throughput of 300‑800 kg/h.
For bakery and dessert producers, a typical 3‑deck configuration is as follows:
Upper deck (coarse screen, 8‑20 mesh) – intercepting large lumps and foreign matter. This deck removes large lumps, fibre agglomerates, packaging debris, and other foreign matter – protecting material purity at the source. The coarse particles screened out can be used directly for decorative sprinkling on bread surfaces, maintaining visual texture.
Middle decks (grading screens, 20‑80 mesh) – achieving particle size grading. This is the core of multi‑deck grading. By setting screens of different mesh sizes, coconut flakes are precisely separated by particle size into different grades – coarse particles for pastry fillings and surface decoration, medium‑fine particles for desserts and biscuits, and ultra‑fine powder for premium desserts and chocolate centres.
Lower deck (safety screen) – ensuring finished product purity. As the final checkpoint, it further intercepts fine impurities – ensuring reliable purity of coconut flakes entering the packaging stage.
The value of "one feed, multiple outputs":
Combined processes, reduced material transfer. In traditional modes, different specification grading often requires 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 adjust or change the corresponding screen decks – no need to replace the entire machine.
High grading accuracy – eliminating size mixing and cross‑contamination. The precise multi‑deck grading ensures purity of each particle size grade – effectively preventing mixing between different specifications.
Gaofu's S49 series coconut flakes 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 a spiral outward trajectory – 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 materials such as coconut flakes. This unique motion pattern gives coconut flakes ample opportunity for dispersion and tumbling on the screen surface – effectively reducing static accumulation of fines on the mesh.
The unique value of three‑dimensional vibration for multi‑deck grading:
Thorough material dispersion – balanced operation across all decks. 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.
Long screening path – more precise fineness control. 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.
Throughput suitable for large‑scale production. Coconut flakes screening throughput of 300‑800 kg/h meets the capacity needs of medium‑sized bakeries to large‑scale dessert producers.
The most common challenge in coconut flakes screening is blinding – if one deck becomes blocked, the accuracy of the entire classification system is compromised. Gaofu's S49 series coconut flakes rotary vibrating sieve provides solutions across multiple levels:
Bouncing ball cleaning system – continuous knocking, real‑time blinding prevention. Food‑grade silicone bouncing balls are installed below the screen – during operation, they continuously knock against the screen, dislodging fine powder adhering to the screen and particles wedged in the mesh. This "screening‑while‑cleaning" design keeps the screen fully permeable throughout the screening process.
Anti‑blinding structural design – reducing blinding from the design perspective. The screen tensioning structure ensures a flat screen surface, minimising material accumulation dead zones. Combined with an adjustable excitation angle design, blinding risk is further reduced.
Fully enclosed structure – solving dust emission problems. The equipment features a fully enclosed structure – fundamentally solving the dust emission problem of traditional screening processes. For materials with high fines content and easy airborne dispersion like coconut flakes, this design improves the workshop environment while reducing material loss.
In actual coconut flakes screening operations, Gaofu's S49 series multi‑deck grading coconut flakes rotary vibrating sieve has demonstrated proven results:
Significantly improved product quality. Through precise multi‑deck grading, product particle size uniformity and purity are ensured. Customer feedback shows product qualification rate increased from 85% to over 95% , with annual returns loss reduced by RMB 120,000.
Notably increased production efficiency. The anti‑blinding design and automatic slag discharge enable continuous operation. Throughput increased from 180 kg/h to 350 kg/h – an improvement of over 90%.
Effective control of raw material loss. The fully enclosed structure reduces material spillage and waste during screening – annual raw material waste reduced by RMB 100,000.
Supports 24‑hour continuous production. The equipment operates stably – supporting long‑duration continuous operation to meet high‑volume production needs while reducing environmental pollution.
