In production scenarios involving starch, powdered sugar, flour, milk powder, seasoning powders, and other food powders, production lines often need to switch frequently between different materials. This rotating production model places several special requirements on filtration equipment:
Quick disassembly. During line changeovers, screens often need to be replaced according to material fineness requirements – from 80 mesh for starch to 120 mesh for powdered sugar, and then to 60 mesh for seasoning powders. If the screen change process is cumbersome and time‑consuming, the entire production line's waiting time is extended – directly affecting production efficiency.
Thorough cleaning. The most critical aspect of switching between different materials is preventing cross‑contamination. Powdered sugar residue mixed into starch, or chilli powder residue mixed into five‑spice powder – any cross‑contamination can cause product flavour deviation or even food safety risks. The equipment structure must support rapid and thorough cleaning, leaving no dead corners.
Flexible mobility. When multiple production lines are used in rotation, filtration equipment may need to be moved between different lines. Equipment that is bulky, heavy, or difficult to move restricts production line layout flexibility.
Gaofu's filtration sieve features a quick‑release screen frame design – significantly simplifying the most time‑consuming step in traditional screen change operations. The equipment features a unique screen frame structure – screen changes are easy, operation is simple, and cleaning is convenient.
Screen changes take only 3‑5 minutes and can be completed by a single operator. Release the locking mechanism, remove the old screen, lay down the new screen, and lock it – the entire process requires no special tools and no multi‑person coordination.
In multi‑product rotating production scenarios, this design means that every product changeover – from powdered sugar to starch, from starch to seasoning powders – is compressed to the minimum downtime, significantly improving equipment utilisation. Screens have long service life and are easy to replace – greatly reducing maintenance costs and downtime.
Cleaning efficiency during product changeovers directly determines the feasibility and product safety of multi‑product rotating production. Gaofu's filtration sieve incorporates multiple targeted design features for cleaning convenience:
No dead corners – easy internal and external cleaning. The equipment structure is well‑designed – both internal and external surfaces are easy to clean. All material‑contact parts are made of stainless steel with smooth surfaces – no dead corners, no burrs. The equipment is small and lightweight – making full use of available space and easy to move.
Easy disassembly – thorough cleaning. The quick‑release structure allows the equipment to 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.
Fully enclosed structure – reducing dust pollution. The equipment features proper sealing design – powder does not disperse during operation. For food powders with high fines content and easy airborne dispersion, this design improves the workshop environment while reducing material loss.
Food powders are widely used in food processing applications – placing extremely strict hygiene standards on production equipment. Gaofu's filtration sieve uses high‑quality stainless steel for all material‑contact parts – meeting food‑grade hygiene standards.
Corrosion‑resistant and easy to clean. Stainless steel offers excellent corrosion resistance and oxidation resistance – with smooth surfaces that resist material adhesion and are easy to clean. When switching between different materials, cleaning is more efficient.
No dead corners. Fine surface finishing ensures smooth equipment surfaces – leaving no room for bacterial growth – providing equipment‑level food safety assurance in multi‑product rotating production.
Gaofu's filtration sieve is small and lightweight – making full use of available space and easy to move. The equipment can be installed in any required position and is easy to relocate.
For companies with multiple food powder production lines, this means filtration equipment can be flexibly deployed between different lines according to production schedules – filtering powdered sugar on Line 1 today, moving to Line 2 for starch tomorrow, and shifting to Line 3 for seasoning powders the day after. One machine serves multiple production lines – higher equipment utilisation and faster return on investment.
While flexibility and easy‑cleaning address multi‑product changeover efficiency, filtration precision is the direct guarantee of product quality. Gaofu's filtration sieve delivers reliable quality assurance for rotating multi‑category production:
Screens down to 400 mesh – non‑blocking mesh, no powder emission. The filtration sieve can screen down to 400 mesh , with a screening particle size range covering 0.038‑5 mm. For typical food powder filtration requirements, this accuracy capability provides ample margin – ensuring consistent finished product fineness.
Automatic impurity discharge – supporting continuous operation. Impurities and oversize material are automatically discharged from the filtration sieve, enabling automated operation. Operators do not need to stop frequently to clean the screen surface – the equipment can run continuously, increasing effective output per unit time.
High screening and filtration efficiency – wide applicability. The filtration sieve offers high screening and filtration efficiency – suitable for any granules, powders, and viscous liquids. Whether for dry screening of starches and powdered sugars or filtration of slurries, it delivers reliable results.
Gaofu's filtration sieve is widely used for screening and filtration of various food powders and slurries, including but not limited to:
Powders: Flour, starch, powdered sugar, milk powder, rice flour, seasoning powders, protein powder, food additive powders, etc.
Slurries: Fruit juices, syrups, beverage bases, etc.
Seasonings: Chilli powder, pepper powder, Sichuan pepper powder, five‑spice powder, monosodium glutamate (MSG), etc.
Others: Yeast, fish meal, soy flour, etc.
