Screening coconut milk is far more complex than it appears.
First, fibre entanglement. Coconut meat is rich in dietary fibre, which forms fibre strands of varying lengths during grinding. These fibres tend to wrap around the screen mesh during screening, gradually building up into a "fibre layer" that blocks the openings. Once the mesh is clogged, screening efficiency drops sharply, forcing production to stop for cleaning.
Second, high viscosity of the slurry. Coconut milk contains significant amounts of coconut oil and protein, giving it a relatively thick consistency. High‑viscosity materials flow poorly on the screen surface and tend to linger, further aggravating the risk of clogging.
Third, strict hygiene requirements. Coconut milk is a food product intended for direct consumption, so screening equipment must comply with food‑grade sanitary standards. The equipment's material, sealing performance, and ease of cleaning all directly affect food safety.
Traditional manual straining or simple screening methods either suffer from low efficiency or cannot guarantee filtration accuracy. Coconut milk producers urgently need a solution that achieves both efficiency and quality at the screening stage.
To address the screening needs of coconut milk and other plant‑based beverages, Gaofu Machinery offers the S49 series Rotary Vibrating Sieve (also known as a three‑dimensional vibrating screen or circular vibrating screen), delivering a professional screening solution for coconut milk producers.
The core strength of this equipment lies in its unique three‑dimensional vibration principle. A vertical vibration motor serves as the excitation source, with eccentric weights installed at both the upper and lower ends of the motor. As the motor rotates, the eccentric weights convert the rotary motion into a compound motion in horizontal, vertical, and inclined directions. This three‑dimensional composite motion is transmitted to the screen surface, causing the material to move not simply by sliding or bouncing, but in a spiral spreading trajectory.
The benefits of this motion pattern are clear: the material continuously tumbles and disperses on the screen surface, giving every fine particle ample opportunity to contact the mesh and pass through. Rather than being "squeezed" through the screen, the particles are "thrown" toward it – significantly reducing the probability of mesh blockage.
Gaofu's Coconut Milk Rotary Vibrating Sieve is not a mere off‑the‑shelf application of a general‑purpose unit. It incorporates several targeted optimisations for liquid food screening applications such as coconut milk:
Food‑grade stainless steel construction for safety. All parts that come into direct contact with coconut milk can be manufactured from SUS304 or 316L food‑grade stainless steel. The stainless steel surface is finely finished to resist material adhesion and is easy to clean and sterilise. The overall design complies with GMP standards, meeting the strict hygiene and safety requirements of the food industry.
High‑precision filtration down to micron levels. Coconut milk screening needs to remove not only visible fibres and debris, but also microscopic insoluble proteins and charred particles. Gaofu's rotary vibrating sieve can achieve screening accuracy up to 600 mesh (0.02 mm) and filtration accuracy down to 5 microns. From coarse impurity removal to fine filtration, a single unit covers the full range.
Multi‑deck configurations for flexible operation. Different coconut milk products require different filtration fineness – coconut juice drinks may only need to remove coarse fibres, while coconut milk powder raw materials may demand much finer filtration. Gaofu's rotary vibrating sieve supports 1 to 5 screen decks that can be flexibly combined according to actual needs. One machine can simultaneously perform coarse and fine screening in a single pass.
Fully enclosed construction for clean production. As coconut milk is a food beverage, the screening process must prevent external contamination. Gaofu's rotary vibrating sieve adopts a totally enclosed design, ensuring that the material is processed in a sealed environment, effectively preventing dust emission and foreign matter ingress. The closed structure also minimises the loss of coconut aroma, helping preserve product flavour.
Continuous operation with automatic residue discharge. Traditional filtration methods require frequent shutdowns for residue cleaning, which hinders production efficiency. Gaofu's rotary vibrating sieve supports continuous operation; impurities and coarse materials are automatically discharged during screening. Producers can maintain a continuous, line‑based production flow without frequent interruptions.
Quick screen changes and easy maintenance. Screen mesh is a consumable item that requires periodic replacement. Gaofu's rotary vibrating sieve features a unique separate mother‑screen and sub‑screen design, allowing screen changes to be completed in just 3 to 5 minutes. This reduces maintenance downtime and lowers the cost of screen consumables.
Low noise and smooth operation. The equipment operates with noise levels controlled to below 75 decibels, contributing to a better working environment.
Gaofu's rotary vibrating sieve is not only suitable for coconut milk screening and filtration, but also widely applicable to other coconut products such as coconut water, coconut cream, and coconut oil for solid‑liquid separation and impurity removal. In a typical coconut milk production process – involving coconut cracking, water extraction, shredding, drying, and grinding – screening is the critical step that links upstream and downstream processes. After screening, the coconut milk proceeds to blending, homogenisation, filling, sterilisation, and other steps before becoming the finished product on shelves.
Moreover, the equipment can be adapted for other plant‑based beverages, including soy milk, oat milk, and almond milk, as well as liquid foods like fruit juices, teas, and condiments that require screening and filtration. One machine, multiple applications – offering flexible screening choices for food and beverage manufacturers.
