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 – 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 that further worsen blinding and affect 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.
At the same time, different applications in bakery and dessert production require different coconut flake particle sizes:
8‑20 mesh coarse particles: For decorative sprinkling on bread surfaces, maintaining visual texture
20‑80 mesh medium‑fine particles: For pastry fillings and dessert making
80‑120 mesh ultra‑fine powder: For premium desserts and chocolate centres
Coconut flakes screening mesh typically ranges from 8 to 120 mesh , with throughput requirements of 300 to 800 kg/h. How to simultaneously produce multiple particle size specifications in a single feed to meet the needs of different applications has become a key challenge for coconut flake processors seeking to improve production line efficiency and product added value.
The core advantage of Gaofu's GFBD series coconut flakes tumbler screen lies in its flexible multi‑deck screen configuration capability. The equipment supports 1 to 5 screen decks , enabling a single machine to simultaneously complete 5 to 6 particle size grades of separation or filtration. Effective screening diameters cover from Φ600 mm to Φ3200 mm – flexible selection according to different capacity requirements. Screening fineness reaches up to 500 mesh or 0.028 mm.
For coconut flake processors, a typical multi‑deck configuration is as follows:
Upper deck (coarse screen) – producing coarse coconut flake particles. Intercepts large lumps and fibre agglomerates – simultaneously producing 8‑20 mesh coarse particles for decorative sprinkling on bread surfaces.
Middle decks (grading screens) – producing medium‑fine coconut flake particles. This is the core of multi‑deck grading. By setting screens of different mesh sizes (20 mesh, 40 mesh, 60 mesh, 80 mesh), coconut flakes are precisely separated by particle size into different grades – 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 specifications simultaneously":
Combined processes, reduced material transfer. In traditional modes, different specification grading often requires multiple machines or multiple screening passes. Gaofu's tumbler screen 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 – screening efficiency reaches over 95% – effectively preventing mixing between different specifications.
The design philosophy of Gaofu's GFBD series coconut flakes tumbler screen draws inspiration from a simple yet effective reference – human hand screening.
The action of hand screening is "rocking" and "swaying" – holding the screen frame with both hands and moving it back and forth, left and right, at a gentle rhythm. Material rolls, disperses, and stratifies on the screen surface, with fines naturally passing through the mesh. This action is effective because it is gentle – material moves on the screen surface without agitation, giving fines sufficient time to find and pass through mesh openings while coarse particles gradually move to the screen edges.
Gaofu's coconut flakes tumbler screen does precisely reproduce the motion logic of hand screening with mechanical precision. Its principle involves an adjustable‑eccentricity exciter generating non‑linear three‑dimensional motion – the instantaneous motion of material is the synthesis of radial displacement and circular motion around that displacement (spiral motion). The material's motion on the screen surface closely resembles manual hand screening: continuously rolling, dispersing, and spreading outward in an involute spiral toward the screen periphery.
Gentle acceleration combined with low‑speed operation ensures material continuously rolls forward on the screen surface, rather than being violently thrown up and dropped. Material disperses evenly across the entire screen surface from the centre to the periphery, propagating in a spiral motion. At the same time, vertical acceleration enables fine particles to effectively pass through the screen surface.
In simple terms: conventional vibrating screens make coconut flakes "bounce" through the screen, while Gaofu's coconut flakes tumbler screen makes coconut flakes "roll" through the screen. The former involves violent impact and bouncing, while the latter involves gentle rolling and sliding – the mechanical impact force on the material is significantly reduced, and coconut flake particles are not broken by violent impact during screening – particle integrity is effectively protected.
The most common challenge in coconut flakes screening is blinding – if one deck becomes blocked, the accuracy of the entire classification system is compromised. Coconut flakes are high‑fat, adhesion‑prone, and blinding‑prone – Gaofu's GFBD series coconut flakes tumbler screen provides solutions across multiple levels:
Multiple cleaning system options. The equipment can be equipped with bouncing ball cleaning, brush cleaning, air‑jet cleaning, and ultrasonic cleaning systems. Bouncing balls continuously knock against the screen surface through frequency vibration – enabling smooth material passage and effectively solving blinding. For sticky or static‑prone products, air‑jet cleaning systems can be selected. Ultrasonic cleaning systems effectively solve screen blinding problems for highly adsorbable, high‑static materials.
Food‑grade stainless steel construction. All coconut flakes‑contact parts are made of 304 or 316L food‑grade stainless steel – with finely polished surfaces, no dead corners, and easy cleaning – fully compliant with food‑grade hygiene standards.
Fully enclosed dust‑proof structure. The equipment features a fully enclosed structure with optional airtight and vacuum designs. Apart from the existing ventilation system, the equipment requires little to no additional air purification or dust collection auxiliary devices – improving the workshop environment while reducing material loss.
Low‑noise, low‑energy operation. Thanks to its simple modular design and low‑speed operation, the GFBD tumbler screen maintains noise levels consistently between 60 and 70 decibels. A small unit requires only 0.25 kW of drive power, and even a large 2‑tonne unit needs only 5.5 kW.
Quick maintenance – supports 24‑hour continuous production. The equipment can be simply and quickly disassembled and reassembled in as little as 15 minutes. Screen changes take only 3‑5 minutes. The equipment supports 7×24‑hour full‑load continuous operation, meeting high‑volume production needs.
In bakery and dessert production, different applications require completely different coconut flake particle sizes – coarse particles for surface decoration, medium‑fine particles for fillings, and ultra‑fine powder for premium desserts. Conventional single‑deck screening equipment can only produce one specification at a time – struggling to meet the needs of multi‑product production.
Gaofu Machinery's GFBD series coconut flakes tumbler screen – with its multi‑deck grading for multiple specifications from one machine, hand‑screening mimicking rocking motion for particle integrity protection, multiple cleaning systems for overcoming blinding, and fully enclosed dust‑proof structure for clean production – provides coconut flake processors with a complete solution from coarse screening to fine grading.
