Over 10,000+ customers' choice, Focus on screening industry 40+ years
Competition in the milk tea market is no longer a single‑dimensional contest of "whether it tastes good or not." From classic original flavour to taro boba, from matcha latte to brown sugar dirty, consumer demand for flavour diversity is driving manufacturers to continuously introduce new products. A medium‑sized milk tea powder processing plant often has a product line covering more than a dozen or even dozens of flavours – original, matcha, chocolate, strawberry, taro, mango, coconut… each with its own specific formulation and fineness standards.
However, multiple flavours bring a real production challenge: frequent product changeovers.
Traditional screening equipment often requires considerable time for screen changes and equipment cleaning when switching between products. Taking a standard rotary vibrating sieve as an example, a single screen change typically takes over half an hour – removing the old screen, cleaning residual material, laying a new screen and refastening – a time‑consuming and labour‑intensive process. If three or four flavours need to be switched in a single day, screen changes and cleaning alone can consume most of the shift. Production lines stop frequently, overall capacity is significantly compromised, and the risk of cross‑contamination between different flavours remains ever‑present if cleaning is not thorough.
In milk tea powder production, screen change speed directly determines the flexible production capability of the production line.
Quick‑Change Screen: An Efficiency Leap from "Half an Hour" to "3 to 5 Minutes"
The quick‑change screen capability of the Gaofu S49 series milk tea rotary vibrating sieve comes from its unique mother‑child screen frame structure.
Mother‑Child Screen Structure: Change Screens Without Changing Frames
Traditional screening equipment uses an integrated screen and frame structure. Changing the screen requires removing the entire frame, peeling off the old screen, laying a new screen, and refastening – a time‑consuming process that typically takes over half an hour.
The Gaofu mother‑child screen frame structure completely simplifies this process. The mother screen provides structural support and is permanently fixed to the frame for long‑term use. The child screen (working screen) is responsible for screening and can be replaced independently. When changing the screen, simply remove the clamp ring of that deck, take out the screen frame, remove the old child screen, lay a new child screen, and clamp it tight. No other components need to be disassembled, and the mother screen does not need to be replaced.
Screen change time is reduced from over half an hour to just 3 to 5 minutes.
One‑Person Operation, No Tools Required
Another advantage of the mother‑child screen frame structure is its simplicity of operation. No complex tools are needed – simply loosen the locking clamp ring to complete screen removal and replacement. An experienced operator can complete the screen change independently within minutes.
Long‑Term Use of Mother Screen, Reduced Consumable Costs
The mother‑child screen design not only improves screen change speed but also extends the overall service life of the screen. The mother screen provides structural support and can be used for a long time, with only the child screen (working screen) needing replacement according to product mesh size requirements. This design both reduces consumable screen costs and minimises waste from frequent full‑screen replacements.
The quick‑change screen design delivers three direct benefits in the scenario of alternating production of multiple milk tea powder flavours.
Benefit 1: Significantly reduced product changeover time, substantially improved line flexibility.
Different milk tea powder flavours have different fineness requirements. Original flavour typically requires 80 to 120 mesh, matcha powder requires finer – 200 mesh or higher – while milk tea powders containing particles (such as coconut jelly or boba) need coarser screens to preserve particle integrity.
The quick‑change screen design of the Gaofu milk tea rotary vibrating sieve allows switching between different mesh sizes in just 3 to 5 minutes. A single production line can easily complete alternating production of multiple flavours in a single day without requiring dedicated screening equipment for each flavour. One machine, multiple screens, switched on demand – the flexible production capability of the line is qualitatively improved.
Benefit 2: More thorough cleaning, effective isolation of cross‑contamination risk.
The greatest risk in alternating multi‑flavour production is cross‑contamination. Residual matcha powder from the previous batch mixing into the next batch of strawberry powder not only affects product appearance but directly impacts taste and food safety.
The mother‑child screen frame structure of the Gaofu rotary vibrating sieve allows the screen to be removed quickly, and the equipment interior has no hygiene dead corners. During screen changes, operators can simultaneously perform thorough cleaning of the equipment interior, ensuring that material residue from different flavours is effectively removed. Quick screen change and thorough cleaning are completed simultaneously – physically eliminating cross‑contamination.
Benefit 3: Minimised downtime, maximised overall capacity.
The downtime during product changeovers on traditional screening equipment is often measured in hours. The Gaofu quick‑change screen design compresses this time to just a few minutes. For milk tea powder production lines that need to switch between multiple flavours daily, the time saved directly translates into increased capacity. A few minutes of screen change time yields a full day of efficient line operation.
Food‑Grade Design: Hygienic Assurance for Milk Tea Powder Production
As a food ingredient that is directly brewed and consumed, milk tea powder requires strict hygiene standards for production equipment. Beyond the quick‑change screen structure, the Gaofu S49 series milk tea rotary vibrating sieve incorporates systematic food‑grade design:
304/316L stainless steel. All material‑contact parts are made of food‑grade 304 stainless steel , with 316L stainless steel available upon request. Surfaces are mirror‑polished (Ra ≤ 0.8μm) with no hygiene dead corners.
Fully enclosed sealed structure. The equipment has a fully enclosed design, effectively preventing dust escape during screening. The fully enclosed structure also blocks external moisture and foreign matter from entering the screening system, ensuring the purity of the milk tea powder.
Dead‑corner‑free design. The simple structure has no hygiene dead corners and supports rapid disassembly for cleaning. Combined with the quick‑change screen design, cleaning during flavour changeovers is more thorough and efficient.
Food‑grade silicone seals. Seals are made of food‑grade silicone, non‑toxic and odourless, ensuring that the entire screening process does not contact any non‑food‑grade materials.
While quick‑change screens solve the problem of "flexible switching," the core task of milk tea powder screening – efficient classification and impurity removal – also requires solid technical support.
The Gaofu S49 series milk tea rotary vibrating sieve operates on the three‑dimensional gyratory motion principle. The equipment uses a vertical vibration motor as the excitation source, with eccentric weights installed at the upper and lower ends of the motor shaft converting the rotational motion into compound motion in horizontal, vertical and tilting directions.
The value of this three‑dimensional motion for milk tea powder screening lies in two aspects:
First, thorough material loosening and natural breaking of lumps. The milk tea powder moves in a spiral outward trajectory on the screen surface, continuously rolling and shifting. Moisture‑induced lumps are naturally broken apart during the motion, preventing adhesion layer formation on the screen surface.
Second, extended screening path and high accuracy. The material travels along a spiral trajectory, giving every particle multiple opportunities to contact the screen. The equipment can achieve screening fineness up to 600 mesh (0.02 mm) and filtration precision down to 5 microns. From 80‑mesh impurity removal for regular milk tea powder to 200‑mesh fine classification for matcha powder, a single machine covers the full range of requirements.
The equipment supports 1 to 5 screen decks , enabling simultaneous separation into 2 to 6 grades. Impurities and oversize material are automatically discharged, enabling continuous operation.
Application Value
From the perspective of actual production conditions in alternating multi‑flavour milk tea powder processing, the Gaofu S49 series milk tea rotary vibrating sieve delivers value in four dimensions:
Flexibility value – The mother‑child screen frame structure enables screen changes in just 3 to 5 minutes. One machine, multiple screens, switched on demand from 80 mesh to 200 mesh. The same machine can simultaneously cover the production needs of multiple flavours – original, matcha, strawberry, chocolate and others – without requiring dedicated screening equipment for each flavour.
Quality value – By flexibly changing screens, the fineness of different milk tea powder flavours is precisely controlled. Regular flavours use 80‑120 mesh screens to ensure basic texture, while fine flavours such as matcha switch to 200 mesh or finer screens for ultimate refinement. Finished milk tea powder has uniform fineness and high purity, and product quality consistency is reliably assured.
Hygiene value – Food‑grade 304/316L stainless steel, dead‑corner‑free design and fully enclosed structure make the equipment easy to clean with no material residue. Quick screen change and thorough cleaning are completed simultaneously, effectively preventing cross‑contamination between different flavours. This helps enterprises meet the hygiene requirements of food GMP and HACCP systems.
Efficiency value – Quick screen changes reduce product changeover time from over half an hour to 3 to 5 minutes; three‑dimensional gyratory motion ensures stable and efficient screening; impurities are automatically discharged without manual intervention; the equipment can run 24 hours continuously. The overall capacity of the production line is fully utilised.
