Over 10,000+ customers' choice, Focus on screening industry 40+ years
In food and beverage powder production, GMP standards set clear requirements for screening equipment:
Material compliance. All parts that come into direct contact with materials must be made of 304 or 316L stainless steel , with polished surfaces to reduce material residue and microbial adhesion risks.
No dead corners. The equipment interior should use rounded transitions to minimise dead corners – facilitating disassembly, cleaning, and cleaning validation.
Fully enclosed dust‑proof design. The equipment must have good sealing performance – effectively preventing dust emission during screening and avoiding cross‑contamination between different batches.
Easy‑clean design. The equipment must meet regular cleaning and validation requirements – modular quick‑release structures and clamp‑type screen frame designs reduce disassembly time, enabling thorough cleaning of screens, frames, and seals.
Gaofu's S49‑AC series ultrasonic vibrating sieve is fully designed in accordance with GMP management standards – complying with the national pharmaceutical vibrating sieve standard JB/T 20034‑2017.
Creamer powder contains vegetable fat – during screening, it tends to adhere to equipment walls and screen surfaces. If the equipment interior is rough or has dead corners, residual material is not only difficult to clean but can also become a breeding ground for microorganisms – directly affecting the quality and safety of subsequent batches.
Gaofu's S49‑AC series ultrasonic vibrating sieve uses SUS304 or SUS316L stainless steel for all material‑contact parts – with mirror‑polished surfaces and surface roughness Ra≤0.8μm – no burrs, no dead corners.
The practical value of mirror‑polished surfaces:
No material residue. Smooth surfaces prevent creamer powder from adhering – simple rinsing removes residue after cleaning – significantly reducing changeover time between batches.
No microbial growth. The dead‑corner‑free design physically prevents material residue and microbial adhesion – leaving no room for bacterial growth.
Cleaning validation is simpler. Smooth surfaces facilitate cleaning validation – complying with GMP requirements for equipment cleaning validation.
Supports CIP/SIP online cleaning. The equipment structure supports Clean‑In‑Place (CIP) and Steam‑In‑Place (SIP) – meeting batch‑to‑batch cleaning requirements for the pharmaceutical and food industries.
When multiple beverage powder production lines are used in rotation, equipment disassembly efficiency directly determines changeover downtime. Gaofu's S49‑AC series ultrasonic vibrating sieve features a quick‑release clamp‑type screen frame design – easy to disassemble, clean internally and externally, with no dead corners.
The practical value of the quick‑release structure:
Screen changes in just 3‑5 minutes. Release the clamps, remove the old screen, lay down the new screen, and tighten the clamps – the entire process requires no special tools and can be completed by a single operator. From creamer to coffee powder, from coffee powder to meal replacement powder – every product changeover is compressed to the minimum downtime.
Easy disassembly for cleaning. The equipment can be quickly disassembled into individual components – enabling thorough cleaning of every part that contacts materials. No material accumulation inside the machine – no residue after cleaning – effectively preventing cross‑contamination between different products.
Adapts to multi‑product rotating production. The quick‑release structural design facilitates rotating production of multiple pharmaceutical and food powders – particularly suitable for small‑batch, multi‑product beverage powder production needs.
Creamer powder contains fat, has high fineness, and low bulk density – during screening, friction readily generates static electricity, causing fine powder to adhere to the screen and cause blinding. Frequent blinding constantly disrupts the rhythm of rotating production.
Gaofu's S49‑AC series ultrasonic vibrating sieve features a three‑dimensional rotary vibration + 36 kHz high‑frequency ultrasonic dual‑drive system – ultrasonic energy is conducted to the screen surface, generating high‑frequency micro‑vibration that effectively breaks down material adhering to the mesh.
How ultrasonic technology supports rotating production:
Continuous blinding prevention – reduced stoppages. High‑frequency vibration keeps fine powder in a "suspended" state – preventing adhesion to the screen. Screen permeability is consistently maintained at high levels – eliminating frequent stoppages for cleaning.
Dual improvement in screening accuracy and throughput. The ultrasonic vibrating sieve changes the contamination and wear caused by conventional screening methods on powders – screening accuracy can be improved by 1% to 70%, and throughput increased by 0.5 to 10 times.
No contact‑based cleaning components required. No bouncing balls or other cleaning consumables – eliminating the risk of rubber debris contaminating the material – more compliant with GMP requirements for high‑cleanliness production.
In multi‑product rotating production, cross‑contamination is the most critical risk to prevent. Gaofu's S49‑AC series ultrasonic vibrating sieve features a fully enclosed sealed structure with pharmaceutical‑grade silicone seals – effectively preventing dust emission and microbial ingress.
The practical value of the fully enclosed structure:
No dust dispersion. The fully enclosed structure effectively prevents dust emission during screening – improving the workshop environment while reducing material loss.
Preventing cross‑contamination. Different materials flow in their own independent enclosed systems – physically preventing cross‑contamination.
Compliant with GMP standards. Fully enclosed, dust‑free design with no dead corners – meeting the requirements of Grade D and above clean workshops.
