The objectives of coconut flake screening are very clear: impurity removal and classification.
From a process perspective, coconut flake processing typically follows the flow of "raw material pre‑treatment (washing, crushing) → coarse grinding → screening → fine classification". The screening step plays a critical role in connecting upstream and downstream operations – it must both remove impurities such as fibre fragments and hard shell particles from the coarsely ground material, and separate the coconut flakes into different particle size grades to meet the requirements of various downstream applications, including baking, fillings, snacks and others.
Specifically, coconut flake screening typically requires a wide mesh range from 8 to 120 mesh. The throughput needs to reach 300 to 800 kg/hour to meet the demands of large‑scale continuous production.
These requirements mean that a qualified coconut flake screening machine must operate stably across a broad particle size range from 8 to 120 mesh while maintaining high throughput – both requirements combined place significant demands on screening accuracy, anti‑blinding capability and continuous operational stability.
The Gaofu S49 series rotary vibrating sieve for coconut flakes uses a vertical vibration motor as the excitation source. Eccentric weights installed at the upper and lower ends of the motor shaft convert the rotational motion into a horizontal, vertical and tilting three‑dimensional compound motion, which is then transmitted to the screen deck.
The direct effect of this technical principle is that the material moves on the screen surface in a spiral outward trajectory, rather than simply bouncing up and down. By adjusting the phase angle of the upper and lower eccentric weights, the material‘s travel path on the screen surface can be changed to suit different material characteristics and screening requirements.
For a fluffy, oily, easily blinding material such as coconut flakes, the benefits of three‑dimensional gyratory motion are tangible. The material continuously tumbles and disperses on the screen surface, so fibres do not concentrate and wrap around a single area, and oily material does not accumulate locally to form an adhesive layer. Compared with single‑direction reciprocating vibration, three‑dimensional motion provides more thorough contact between the material and the screen, resulting in higher screening efficiency.
The Gaofu S49 series rotary vibrating sieve supports 1 to 5 screen decks, allowing a single feed to complete multi‑stage classification simultaneously. In coconut flake screening, a single deck can be used for impurity removal, or multiple decks can be configured for coarse and fine classification – coarse screening removes large fibres and hard shell fragments, while fine screening obtains the target‑size finished coconut flakes. Screening accuracy can reach up to 600 mesh (0.02 mm) and filtration precision down to 5 microns.
1. Anti‑Blinding Design
To address the core problems of high oil content and fibre entanglement, the Gaofu rotary vibrating sieve for coconut flakes is equipped with a bouncing ball cleaning system. During screening, silicone or rubber balls placed under the screen deck continuously bounce against the screen cloth, dislodging oily material adhering to the mesh openings and tangled fibres, keeping the screen clear.
At the same time, the high‑frequency, low‑amplitude vibration forms a thin flow layer of material on the screen surface, reducing residence time and further lowering the risk of screen blinding. For ultra‑fine coconut powder or more sticky materials, an optional ultrasonic cleaning system can be added, using high‑frequency ultrasonic vibration to break the adhesion between the material and the screen.
2. Food‑Grade Stainless Steel
Coconut flakes are used directly in food processing, so the equipment material that contacts them must meet clear hygiene standards. All material‑contact parts of the Gaofu rotary vibrating sieve for coconut flakes are made of 304 food‑grade stainless steel, with a mirror‑polished surface, no dead corners, and easy to clean. The equipment meets food GMP requirements. For production lines requiring even higher cleanliness, 316L stainless steel is also available.
3. Fully Enclosed Sealed Structure
During coconut flake screening, dust escape causes both material loss and workshop contamination. The Gaofu rotary vibrating sieve for coconut flakes has a fully enclosed sealed structure, with sealed connections at the inlet and outlet. The screening process takes place inside a sealed chamber – no dust escapes and no material splashes. The fully enclosed design also effectively blocks external moisture, reducing the risk of secondary moisture absorption by the coconut flakes during screening.
4. Continuous Automatic Discharge
After traditional screening equipment runs for a period, residue accumulates on the screen surface and requires stoppage for cleaning. With the Gaofu rotary vibrating sieve for coconut flakes, impurities and oversize material automatically move along the screen surface to the reject port and are discharged. The equipment can run 24 hours continuously without frequent stoppages for cleaning, effectively supporting the continuous operation requirements of large‑scale coconut flake production lines.
5. Quick Screen Change
Different coconut flake products require different particle sizes. The Gaofu S49 series rotary vibrating sieve uses a separate mother‑child screen frame structure, allowing screen changes in just 3 to 5 minutes. The mother screen provides structural support, while the fine screen (working screen) is responsible for screening. When the fine screen wears out or a different mesh size is needed, only the fine screen needs to be replaced; the mother screen can be used for a long time. This design reduces consumable screen costs while shortening production line downtime.
Gaofu rotary vibrating sieves have delivered measurable improvements in actual production. For example, a coconut flake processor in the Philippines reported that after switching to High‑Fu equipment, their product qualification rate rose from 85% to over 95%, cutting annual return losses by USD 12,000. Throughput increased from 180 kg/h to 350 kg/h—a gain of more than 90%—while annual raw material waste was reduced by USD 10,000.
