Over 10,000+ customers' choice, Focus on screening industry 40+ years
Coconut powder, after grinding, must pass through screening to remove plant fibres, lumps, and any potential foreign matter before entering packaging or subsequent processing. In large‑scale production, the throughput challenges in this stage mainly include:
High material volume demands substantial processing capacity per unit time. Modern coconut powder production lines can process several tonnes per hour or more. If screening equipment lacks sufficient capacity, it becomes a direct bottleneck for the entire production line.
Extended continuous operation requires stable and reliable performance. Coconut powder production typically runs 24/7. As a critical link in the line, the screening equipment's stability directly affects overall line utilisation.
Special material characteristics impose high demands on equipment adaptability. Coconut powder has a high fat content (approximately 40%‑60%) and a large proportion of fine particles, making it prone to adhesion and screen blinding during screening. The equipment must maintain screen permeability during prolonged continuous operation to avoid throughput loss caused by blinding.
The linear vibrating screen (also called a linear screen) is an enclosed vibrating screening machine driven by two vibrating motors. Its working principle is: when two vibrating motors mounted longitudinally on the screen body operate in opposite directions, the lateral excitation forces cancel each other out, while the longitudinal excitation forces are transmitted through the vibration‑transmitting body to the entire screen box, causing the screen surface to vibrate in a linear motion. Under the combined action of excitation force and gravity, material is thrown up on the screen surface and moves forward in a straight line in a bouncing motion. Particles smaller than the screen openings pass through to the lower layer, completing screening and grading.
The linear vibrating screen offers the following notable features for high‑capacity impurity removal:
High throughput: The rectangular screen surface provides a large effective area, with capacity adaptable from laboratory scale to large production lines;
Flexible grading: Supports 1 to 5 screen decks, enabling multi‑stage grading in a single feed;
Simple structure, stable operation: Easy maintenance and relatively low failure rate, suitable for long‑term continuous operation;
Fully enclosed design: Prevents dust emission during operation, keeping the workshop clean and reducing material loss;
Moderate energy consumption: Dual‑motor power typically ranges from 0.4 to 4.0 kW, offering reasonable energy efficiency.
With over 40 years of experience in screening equipment, Gaofu Machinery has developed the SZF series linear vibrating screen – a standardised screening machine for powders and granular materials. For high‑capacity impurity removal of coconut powder and other food powders, this series offers the following technical features:
Multiple sizes to cover different capacity needs. The SZF series offers various screen dimensions from 500×2000 mm to 1500×4000 mm, with 1 to 5 screen decks, allowing flexible selection based on actual production requirements.
High grading accuracy and consistent impurity removal. The grading fineness covers 0.075 mm to 20 mm, with grading efficiency reaching over 95%. The output particles are uniform in size with high screening accuracy, effectively removing fibres, lumps, and foreign matter from coconut powder.
Food‑grade material construction. Contact parts can be made of 304 or 316L stainless steel, with smooth surfaces for easy cleaning, meeting food industry hygiene standards.
Fully enclosed, optionally negative‑pressure design improves workshop environment. The fully enclosed structure, optionally with a negative‑pressure extraction system, prevents dust emission during operation, helping maintain a clean workshop environment.
In high‑capacity impurity removal for coconut powder, Gaofu's SZF series linear vibrating screen offers practical value in the following aspects:
Supports large‑scale production. The high processing capacity and stable performance of the linear vibrating screen meet the several‑tonne‑per‑hour demand of coconut powder production lines, ensuring smooth overall line operation.
Improves product quality. By effectively removing fibres, lumps, and foreign matter, the purity and particle size uniformity of the final product are ensured, helping enhance the competitiveness of coconut powder in baking, beverage, and other applications.
Reduces operating costs. The fully enclosed structure minimises spillage and waste during screening; moderate energy consumption keeps long‑term operating costs under control.
Suitable for automated production lines. The linear vibrating screen is designed to work seamlessly with upstream and downstream equipment (such as conveyors, elevators, and packaging machines), enabling integration into continuous coconut powder production lines.
