The typical coconut milk production process is: coconut → shelling, water extraction → shredding → drying → dried coconut shreds → grinding → screening → batching → homogenisation → filling → sterilisation → finished product. Among these steps, screening is the critical node in the entire production process for removing solid impurities and ensuring finished product quality.
During the grinding process, coconut meat is broken down into a slurry, but plant fibres are structurally tough and difficult to completely pulverise. These fibre residues remain suspended in the coconut milk as fine particles – including coconut meat fibres, shell fragments, insoluble proteins, and starch granules. If filtration is not thorough, these problems are directly reflected in the final product:
Rough mouthfeel: Fibre residue creates a gritty texture, affecting beverage smoothness
Sedimentation and separation: Solid impurities settle after standing, affecting product appearance and stability
Equipment blockage: Fibre impurities can cause blockages in subsequent homogenisation and filling processes
Inconsistent quality: Fluctuations in filtration effectiveness between batches lead to unstable product quality
Gaofu's S49 series rotary vibrating sieve (three‑dimensional 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. This unique motion pattern causes the slurry to form a thin‑layer flow on the screen surface, effectively preventing fibrous and viscous materials from accumulating on the screen.
In actual coconut milk filtration applications, Gaofu's rotary vibrating sieve demonstrates targeted technical advantages:
1. High‑precision filtration – fineness assured
Gaofu's rotary vibrating sieve achieves filtration precision down to 5 microns and screening fineness up to 600 mesh (0.02 mm) . In coconut milk screening, the standard configuration is 80 mesh – effectively intercepting coconut meat fibres, shell fragments, and other solid impurities while ensuring smooth passage of the coconut milk slurry.
2. Automatic slag discharge – uninterrupted continuous production
Conventional filtration equipment requires stoppages for slag removal once residue accumulates to a certain level – severely affecting production efficiency. Gaofu's rotary vibrating sieve features automatic slag discharge – during filtration, residue automatically moves along the screen surface to the discharge outlet, eliminating the need for frequent stoppages. This enables 24‑hour continuous production – significantly improving production line efficiency.
3. High‑frequency, low‑amplitude vibration – effective blinding prevention
Coconut meat fibres are sticky and tough – on conventional filtration equipment, they easily block the mesh. Gaofu's rotary vibrating sieve uses high‑frequency, low‑amplitude vibration to create a thin‑layer flow of slurry on the screen surface – coconut meat fibres and other viscous materials are less likely to adhere to the mesh – effectively extending the single filtration cycle.
4. Fully enclosed design – clean production assurance
The equipment features a fully enclosed design – feed inlet, liquid outlet, and slag discharge port are all sealed – preventing coconut juice splashing. This design keeps the workshop environment clean while preventing external contaminants from entering the material.
5. Food‑grade stainless steel construction – safeguarding food safety
All coconut milk‑contact parts are made of 304 or 316L stainless steel – meeting food processing hygiene and corrosion resistance requirements. Surfaces are finely polished with no dead corners – easy to clean and maintain.
In actual coconut milk filtration operations, Gaofu's rotary vibrating sieve delivers tangible improvements:
Significantly improved product mouthfeel. By effectively removing fibre residue and solid impurities from coconut milk, the finished product has a smoother, more refined texture – without the "gritty" sensation. For products like thick coconut cream that require emulsion stability, filtration effectively reduces separation.
Notably increased production efficiency. The automatic slag discharge design enables continuous operation without frequent stoppages. In one coconut milk producer's actual application, after adopting Gaofu's rotary vibrating sieve, single‑unit screening capacity reached 1 tonne per hour.
More consistent product quality. Stable filtration performance ensures batch‑to‑batch consistency in mouthfeel and purity – providing reliable raw material assurance for subsequent homogenisation and filling processes.
When choosing a rotary vibrating sieve for coconut milk production, consider the following aspects:
1. Capacity matching. Select the appropriate model according to the production line's hourly throughput. Coconut milk screening typically achieves 1 tonne/hour – Gaofu's S49 series offers various specifications to meet different production scale requirements.
2. Filtration precision. Coconut milk typically requires 80 mesh – screen mesh can be flexibly adjusted according to product fineness requirements.
3. Material requirements. All coconut milk‑contact parts should be made of 304 or 316L stainless steel – meeting food‑grade hygiene standards.
4. Slag discharge method. For continuous production operations, automatic slag discharge is a key configuration for improving efficiency.
The fibre residue problem in coconut milk may seem like a production "detail" – but it directly affects beverage mouthfeel, quality, and the consumer drinking experience. Gaofu Machinery's S49 series rotary vibrating sieve – with its high‑precision filtration (down to 5 microns), automatic slag discharge for continuous production, high‑frequency low‑amplitude vibration for blinding prevention, and fully enclosed stainless steel structure for hygiene safety – provides coconut milk producers with a professional filtration solution that removes fibre residue at the source and enhances beverage smoothness.
