Over 10,000+ customers' choice, Focus on screening industry 40+ years
The screening stage on creamer production lines faces challenges far more complex than simply "passing powder through a screen":
High‑fat characteristics cause frequent blinding. The fat in creamer powder generates heat through friction during screening, forming a sticky film on the screen surface. Fine powder is "glued" to the mesh by this film, accumulating thicker and thicker until the openings are completely sealed. Conventional screening equipment often suffers from blinding shortly after operation begins – forcing frequent stoppages for cleaning.
Large‑scale production demands high throughput. Modern creamer production lines typically operate 24/7 – the processing capacity of screening equipment directly determines the maximum output of the entire line. If equipment capacity is insufficient, it becomes a direct bottleneck.
Strict hygiene standards – must meet food‑grade requirements. Creamer is widely used in food applications – screening equipment must comply with food‑grade hygiene standards, with all material‑contact parts made of stainless steel and dead‑corner‑free, easy‑to‑clean structural design.
High grading accuracy – must eliminate size mixing and cross‑contamination. Different beverage formulations have different fineness requirements – coffee creamer demands a smooth, delicate texture; milk tea ingredients need medium particles. Screening equipment must precisely separate creamer by particle size into different specifications, with no mixing between grades.
The stability of Gaofu's SZF series creamer linear vibrating screen is not a collection of isolated technical features – it is a systematic engineering achievement encompassing drive principles, screen box structure, screen design, and overall machine materials.
1. Dual vibrating motors in synchronised opposite directions – the foundation of stability
Gaofu's SZF series linear vibrating screen uses dual vibrating motors operating in synchronised opposite directions. Two vibration motors are longitudinally mounted on both sides of the screen body. When they run in synchronised opposite directions, the excitation forces generated by the eccentric blocks at the motor ends cancel each other out in the lateral direction – ensuring stable equipment operation – while superimposing into a reciprocating excitation force in the longitudinal direction, transmitted through the vibration‑transmitting body to the entire screen box.
In simple terms: the two motors "cancel out" lateral vibration and "combine forces" for longitudinal screening – this design generates stable linear vibration on the screen surface, causing material to be thrown up and move forward in a straight line in a parabolic bouncing motion. The material bed is continuously turned, loosened, and stratified on the screen surface – impurities and lumps are effectively intercepted, and fines have ample opportunity to pass through the screen.
The excitation angle can be adjusted within a range of 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 grading accuracy. For different batches of creamer, operators can flexibly adjust the inclination according to material characteristics to achieve the optimal balance between throughput and accuracy.
2. Reinforced screen box structure – capable of long‑duration continuous operation
The screen body of Gaofu's SZF series linear vibrating screen is constructed of high‑quality steel plate welding – beams and the screen box are connected with high‑strength bolts – providing high overall structural strength, no welding stress, and ensuring stability during long‑duration, high‑load operation. The entire machine has a simple and compact structure – with strong rigidity, good impact resistance, and resistance to deformation and cracking.
Screen sizes cover 500×1600 mm to 1500×4000 mm. A larger screening area means more space for material dispersion and more opportunities for particles to pass through the screen – providing the physical foundation for high‑throughput screening of high‑fat creamer.
3. Flexible multi‑deck screen configurations – multiple grades from one feed
The equipment supports flexible configurations of 1 to 5 screen decks , enabling a single machine to produce 2 to 6 different particle size fractions simultaneously. For creamer production, the upper deck intercepts lumps and foreign matter, the middle decks achieve fine grading, and the lower deck acts as a safety screen to ensure finished product purity – one machine, multiple functions – reducing material transfers between units. Screen mesh covers 2 to 500 mesh – flexibly adaptable to different fineness specifications of creamer products.
Screens use a clamp‑type fixing structure – replacements can be made quickly without special tools – significantly reducing downtime and maintenance costs.
4. Fully enclosed stainless steel structure – the safety barrier for food hygiene
Gaofu's SZF series linear vibrating screen features a fully enclosed design – no dust emission, automatic discharge. All material‑contact parts can be made of SUS304 or SUS316L stainless steel – meeting food industry hygiene standards. The entire machine is robust, corrosion‑resistant, and durable – easy to clean internally and externally with no dead corners.
For the food and pharmaceutical industries, Gaofu's linear screen is available in hygienic stainless steel models with rounded corners, no dead corners, and easy cleaning. The entire machine design complies with GMP clean production requirements – providing reliable food safety assurance at the equipment level for creamer. The fully enclosed frame can be paired with a negative‑pressure dust extraction interface – effectively suppressing dust emission and improving the workshop environment.
The structural advantages of Gaofu's SZF series linear vibrating screen translate into quantifiable practical value in large‑scale creamer screening:
Consistently stable screening accuracy. Conventional material screening efficiency reaches over 95%. The stable linear vibration trajectory and proper screen tensioning structure ensure that screening accuracy does not degrade during long‑duration continuous operation – batch‑to‑batch product quality consistency is guaranteed.
Large throughput – matching large‑scale production rhythm. Models cover SZF‑520 to SZF‑1540, with throughput of 15‑500 t/h. For creamer producers with large daily throughput, a single linear screen matches the capacity rhythm of the entire line – the screening stage no longer becomes an efficiency bottleneck.
Blinding is effectively relieved. Material moves forward in a straight line in a bouncing motion – continuously turned, loosened, and stratified – reducing static accumulation of fine powder on the screen surface and lowering the probability of blinding from the motion mechanism. For the fat adhesion problem of high‑fat creamer, the continuous bouncing motion prevents material from retention and accumulating on the screen surface – effectively relieving blinding caused by fat adhesion.
Controllable operating costs. The vibration motors are optimised for low noise, low energy consumption, and long service life. The entire machine has a simple structure – easy maintenance and relatively low failure rates. Screens use a clamp‑type fixing structure – convenient replacement – reducing long‑term consumable and labour costs.
Clean production is assured. The fully enclosed structure ensures no dust emission – meeting environmental requirements; food‑grade stainless steel with no dead corners – meeting food industry GMP standards.
When selecting a linear vibrating screen for creamer processing, it is recommended to evaluate from the following dimensions:
1. Capacity matching
Select the appropriate model according to the production line's hourly throughput. Gaofu's SZF series offers various models from SZF‑520 to SZF‑1540, with throughput covering 15‑500 t/h. During selection, choose the appropriate specification according to actual capacity requirements – reserving some capacity margin for future production expansion.
2. Grading requirements
Determine the number of grades needed (2, 3, or more) – select the number of screen decks (1‑5) accordingly. For creamer production, a typical 3‑deck configuration – upper for impurity removal, middle for grading, lower for safety screening – meets most requirements.
3. Screening accuracy
Select screen mesh according to the target fineness of the creamer product. Gaofu's SZF series covers screen mesh from 2 to 500 mesh. Creamer typically requires 80‑120 mesh screening – premium applications can use finer mesh.
4. Materials and hygiene standards
All creamer‑contact parts should be made of 304 or 316L stainless steel. For the food industry, hygienic stainless steel models with rounded corners, no dead corners, and easy cleaning – compliant with GMP clean production requirements. The fully enclosed structure with a negative‑pressure dust extraction interface can further improve the workshop environment.
5. Operational stability
Pay attention to the drive method (dual vibrating motors in synchronised opposite directions is key to stability), screen box structural strength (reinforced welded structure, high‑strength bolt connections), and the flexibility of vibration parameter adjustment (screen inclination adjustable from 0° to 7°).
