As a plant‑based protein beverage consumed directly, coconut milk production must strictly comply with food hygiene standards throughout the entire process. At the screening stage, equipment must meet the following key rinsing and sanitisation requirements:
No dead corners is the foundation. If the equipment interior has dead corners – such as weld recesses or sharp corners – slurry residue cannot be completely removed through conventional rinsing. Residual coconut milk protein and fat readily support microbial growth at room temperature. The equipment structure must be dead‑corner‑free with no areas for contamination to hide.
Corrosion‑resistant materials are a prerequisite. Coconut milk contains proteins and vegetable oils – prolonged contact with ordinary materials can cause corrosion, not only shortening equipment life but also contaminating the product. All coconut milk‑contact parts must be made of corrosion‑resistant, food‑grade stainless steel.
Rinsing and sanitisation must be convenient and efficient. During multi‑product changeovers or after each shift, the equipment must be quickly rinsed and sanitised to resume production with minimal downtime. The equipment structure should support rapid disassembly and cleaning, and ideally CIP compatibility.
Cleaning effectiveness must be verifiable. Food production regulations require that cleaning effectiveness can be verified. Smooth surfaces and rational structural design facilitate visual inspection and sampling – ensuring the effectiveness of cleaning and sanitisation procedures.
Gaofu's S49 series food‑grade coconut milk rotary vibrating sieve uses 304 or 316L food‑grade stainless steel for all coconut milk‑contact parts – providing the material foundation for rinsing and sanitisation.
316L stainless steel is the preferred material for coconut milk filtration. Coconut milk contains proteins and vegetable oils – prolonged contact can be mildly corrosive to materials. 316L stainless steel – with its added molybdenum content – offers excellent corrosion resistance, effectively resisting long‑term attack from proteins and oils in coconut milk. The equipment does not produce rust particles that could contaminate the product – ensuring coconut milk purity and food safety.
Stainless steel does not absorb or retain material. Compared with carbon steel, stainless steel has a dense, smooth surface – coconut milk slurry cannot penetrate the material. Cleaning simply requires surface rinsing to remove residue. This significantly reduces cleaning time and improves equipment utilisation.
On top of the material foundation, Gaofu's S49 series food‑grade coconut milk rotary vibrating sieve features fine mirror‑polished internal surfaces, achieving surface roughness of Ra≤0.8μm.
In simple terms: mirror‑polished surfaces make the equipment interior as smooth as glass – coconut milk slurry cannot adhere, water rinsing removes residue, and a wipe leaves it shining.
The rinsing and sanitisation advantages of mirror‑polished surfaces:
No material adhesion, no residue. Mirror‑polished surfaces are extremely smooth – proteins and oils in coconut milk cannot adhere to equipment walls. Cleaning is as simple as rinsing with water and wiping with a cloth – significantly reducing cleaning time and improving equipment turnover.
No dead corners. The entire machine is integrally polished – all welds are smooth with no material‑trapping dead corners – leaving no room for bacterial growth. All corners are rounded and polished – no recesses, no gaps for material to hide – thoroughly eliminating food safety risks from equipment contamination.
Easy cleaning validation. Smooth surfaces facilitate visual inspection and cleaning validation – complying with food industry GMP requirements for equipment cleaning validation.
Resistant to CIP/SIP cleaning. Mirror‑polished stainless steel surfaces can withstand CIP (Clean‑In‑Place) and SIP (Sterilise‑In‑Place) processes – providing reliable equipment assurance for high‑cleanliness beverage production lines.
Beyond metal surface treatment, Gaofu's S49 series food‑grade coconut milk rotary vibrating sieve also fully considers rinsing and sanitisation requirements in its seals and overall structure:
Food‑grade silicone seals. All equipment connections use food‑grade silicone seals – with good elasticity, corrosion resistance, and age resistance. Unlike ordinary rubber seals, food‑grade silicone does not harden or crack from prolonged contact with coconut milk – ensuring long‑term sealing system reliability.
Fully enclosed structure – no dust, no splashing. The equipment features a fully enclosed structure – feed inlet, liquid outlet, and slag discharge port are all sealed. The entire screening process – from feeding to liquid discharge and slag removal – takes place within a closed chamber, preventing slurry splashing – keeping the workshop environment clean while preventing external contaminants from entering the material.
Quick‑release structure – easy disassembly and cleaning. The equipment features a quick‑release design – screens, seals, and other components can be quickly removed and installed. After cleaning, the equipment can be rapidly returned to operation – shortening changeover downtime.
For beverage production lines that require frequent product changeovers or thorough cleaning after each shift, Gaofu's S49 series food‑grade coconut milk rotary vibrating sieve is compatible with CIP (Clean‑In‑Place) systems.
The practical value of CIP cleaning:
Automatic cleaning – no disassembly required. CIP systems circulate cleaning solutions (hot water, food‑grade detergents, sanitisers, etc.) to automatically clean the equipment interior – eliminating manual disassembly. This significantly reduces labour intensity and cleaning time.
Thorough cleaning – no residue. Mirror‑polished surfaces combined with CIP circulation effectively remove coconut milk residue from equipment walls. Residue after cleaning can be controlled to very low levels – meeting the requirements of multi‑product co‑production.
Reduced downtime. CIP cleaning can be completed quickly during production gaps – the equipment does not need to be idle for extended periods waiting for manual cleaning – improving equipment utilisation and production line efficiency.
The rinsing and sanitisation design advantages of Gaofu's S49 series food‑grade coconut milk rotary vibrating sieve deliver systematic improvements for plant‑based protein beverage production lines:
Better product quality assurance. The dead‑corner‑free design and stainless steel construction ensure the equipment can be thoroughly cleaned and sanitised – effectively preventing microbial growth and batch‑to‑batch cross‑contamination. Every batch of coconut milk is purified in a clean screening environment – product quality becomes more stable and controllable.
Notably improved production efficiency. The quick‑release structure and CIP compatibility significantly reduce cleaning time – the equipment can be rapidly returned to production for the next batch. For companies requiring frequent product changeovers or multi‑shift continuous production, this efficiency improvement means higher equipment utilisation and lower operating costs.
Easier compliance. The equipment design complies with food industry GMP clean production requirements and meets international food hygiene standards such as FDA. Mirror‑polished surfaces and CIP capability facilitate cleaning validation – helping beverage producers confidently pass various food safety audits.
