Over 10,000+ customers' choice, Focus on screening industry 40+ years
Creamer is produced as a powder after spray drying. The production process typically includes mixing/emulsification, homogenisation, sterilisation, spray drying, and screening. In large‑scale production, the screening stage faces challenges that differ from conventional fine screening:
High throughput requires continuous, efficient operation. Modern creamer production lines can produce several tonnes per hour or more. Screening equipment must have sufficient capacity and run reliably without becoming a bottleneck. Gaofu's SZF series linear vibrating screen offers a large effective screening area – for example, the SZF‑1540 model has a screen width of 1500 mm and length of 4000 mm, providing the physical basis for high throughput.
Clear grading needs demand precise particle size control. Different applications – coffee creamer, milk tea base, bakery ingredients – each have their own particle size specifications. The equipment must be able to classify materials into multiple grades. Gaofu linear vibrating screens support 1 to 5 screen decks, allowing a single machine to produce 2 to 6 different particle size fractions simultaneously.
Continuous production lines require high reliability. Creamer production typically runs 24/7. As a key link in the production line, the screening equipment's stability directly affects the overall line utilisation. Gaofu linear vibrating screens are driven by two synchronised motors, providing uniform vibration without deviation, and can achieve screening efficiency of over 95% for conventional materials.
Strict hygiene standards demand food‑grade construction. Creamer is widely used in coffee, milk tea, bakery, and other food applications, placing high demands on equipment materials and cleanliness. Gaofu linear vibrating screens offer 304 stainless steel contact parts, with a fully enclosed structure that prevents dust emission during operation.
The linear vibrating screen (also called a linear screen) is a general‑purpose, enclosed, light‑duty 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. 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.
Compared with circular vibrating screens, linear vibrating screens offer the following advantages for high‑volume food powder screening:
High throughput: The rectangular screen surface provides a large effective area, with capacities ranging from laboratory scale to large production lines. Material moves in a straight line with a longer screening path, promoting thorough separation.
Precise grading: Supports 1 to 5 screen decks, enabling multi‑grade separation in a single feed. The output particles are uniform in size with high screening accuracy.
Simple structure, stable operation: The straightforward design makes maintenance easy and reduces the likelihood of breakdowns, suitable for long‑term continuous operation.
Fully enclosed design meets food hygiene requirements: The enclosed structure minimises dust emission, keeping the workshop clean and reducing material loss.
Moderate energy consumption: Dual‑motor power typically ranges from 0.4 to 4.0 kW, making energy use reasonable.
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 creamer and other food powder applications, this series offers the following technical features:
Adjustable excitation angle for different materials. Gaofu linear vibrating screens feature an adjustable excitation angle, allowing users to adjust vibration parameters according to the characteristics of creamer and the required screening results. The screen surface inclination can be adjusted from 0° to 7° – a larger inclination increases the leap span and conveying speed, raising throughput per unit time; a smaller inclination prolongs material residence time on the screen, improving fine particle passage and grading accuracy.
Flexible multi‑deck configuration for multi‑stage grading. The equipment supports 1 to 5 screen decks, with mesh sizes selected according to the target particle size of the creamer product. The screening range covers 0.075 mm to 20 mm (approx. 10 to 200 mesh). One feed completes both de‑dusting and multi‑stage grading, with oversize and undersize discharged from separate outlets.
Fully enclosed, optionally negative‑pressure design improves workshop environment. The fully enclosed structure prevents dust escape during operation. A negative‑pressure extraction system can be optionally added to enhance dust control, meeting the cleanliness requirements of food production workshops.
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. The machine is available in carbon steel, 304, or 316 stainless steel to suit different material screening scenarios.
Suitable for integrated production lines. The equipment is designed to work seamlessly with upstream and downstream equipment (such as conveyors and elevators), and can be integrated into continuous creamer production lines for 24‑hour operation.
The linear vibrating screen offers practical value in large‑scale creamer production in the following aspects:
High‑volume capacity supports large‑scale production. The large screening area and efficient throughput of the linear vibrating screen enable it to handle several tonnes per hour, helping ensure smooth operation of the entire production line for high‑output creamer manufacturers.
Multi‑stage grading adds product value. With multiple screen decks, the linear vibrating screen performs de‑dusting, coarse removal, and fine powder grading in one pass. Creamer producers can produce different particle size grades to meet various customer requirements, enhancing market adaptability.
Continuous stable operation reduces downtime risk. The linear vibrating screen has a simple design with fewer moving parts, resulting in a low failure rate. For 24‑hour creamer lines, equipment stability is directly linked to overall line utilisation.
Enclosed design supports food safety. The fully enclosed structure prevents contamination during screening and reduces dust impact on the workshop environment – a valuable feature for creamer producers requiring food safety certifications.
