Over 10,000+ customers' choice, Focus on screening industry 40+ years
Food powder filtration and impurity removal go far beyond simply "removing impurities" – its core value is reflected in three aspects:
Improving product purity and safeguarding food safety. During harvesting, processing, storage, and transport, food raw materials may become contaminated with plant fibres, bran, packaging debris, metal filings, and various other foreign matter. If these impurities are not effectively intercepted, they will directly affect the mouthfeel and safety of the final product. Gaofu's filtration sieve features non‑blocking mesh and no powder emission – capable of screening down to 400 mesh – effectively intercepting fibres, lumps, and hard particles in food powders, ensuring consistent finished product fineness and reliable purity.
Ensuring continuous production and improving line efficiency. 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. For food processing lines requiring long‑duration continuous operation, this means higher equipment utilisation and more stable output.
Adapting to multi‑product production and responding flexibly to market changes. Food processors typically handle multiple product varieties – starch, powdered sugar, seasoning powders, protein powder, etc. – with different fineness requirements for different materials. The filtration sieve features easy screen changes, simple operation, and convenient cleaning – enabling rapid switching between different materials and significantly reducing changeover downtime.
Typical application scenarios of Gaofu's filtration sieve in the food processing industry include:
Fine filtration of starches and powdered sugars. Starches and powdered sugars may become contaminated with fibrous impurities, lumps, and hard particles during processing. The high‑precision filtration capability of the filtration sieve – capable of screening down to 400 mesh – effectively removes these impurities, ensuring uniform fineness and reliable purity. For producers requiring different fineness specifications of starches and powdered sugars, the quick screen change design enables flexible switching between different mesh sizes to meet diverse production needs.
Impurity removal filtration of seasoning powders. Seasoning powders such as chilli powder, pepper powder, Sichuan pepper powder, and five‑spice powder often contain coarse fibres, seed husks, and other impurities during grinding. The single‑deck design of the filtration sieve effectively intercepts these impurities, ensuring seasoning powder purity. The equipment is small and lightweight – making full use of available space and easy to move – particularly suitable for seasoning production workshops with limited space.
Fibre removal from flour and rice flour. Flour and rice flour may become contaminated with bran fibres, packaging fibre debris, and other contaminants during processing. These fibrous impurities not only affect product mouthfeel but can also affect the stability of subsequent processing steps. The high‑precision filtration capability of the filtration sieve effectively removes these fibrous impurities, ensuring the purity of bakery ingredients.
Fine filtration of protein powder and meal replacement powder. Protein powder, meal replacement powder, and similar materials demand extremely high purity – any fine impurity can affect product quality and consumer experience. The filtration sieve's 400‑mesh precision meets the fine filtration requirements of these high‑value food powders.
Slurry filtration. Solid‑liquid separation of syrups, fruit juices, beverage bases, and other liquid materials – removing solid impurities and fibres to improve product clarity and purity. The filtration sieve is suitable for screening and filtration of any granules, powders, and viscous liquids – performing equally well in slurry filtration.
To address the special requirements of food powder filtration, Gaofu's filtration sieve incorporates multiple specialised design and functional optimisations:
High‑precision filtration – precise, controllable fineness. Featuring non‑blocking mesh and no powder emission, capable of screening 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.
Easy screen changes – simple operation, convenient cleaning. The filtration sieve features a unique screen frame design – screens have long service life and are easy to replace. For production lines requiring frequent changeovers between different food powder varieties, this feature significantly reduces changeover downtime and improves equipment utilisation.
Compact size – flexible placement in limited spaces. The filtration sieve is small and lightweight – making full use of available space and easy to move. Whether for sample analysis on the laboratory bench or routine filtration in the production workshop, it can be flexibly positioned without occupying excessive space. The equipment can be installed in any required position and is easy to relocate – adapting to different production line layouts.
High screening and filtration efficiency – wide applicability. Offering high screening and filtration efficiency – suitable for any granules, powders, and viscous liquids. The equipment is durably designed – suitable for any powder or viscous liquid. Whether for dry screening of food powders or filtration of slurries, it delivers consistent filtration performance.
Low‑noise operation – improving the workshop environment. Using a vibration motor as the excitation source, the equipment features high screening efficiency and low noise. Operating noise is ≤85 dB , with amplitude ≤5 mm. For food processing plants looking to improve workshop working conditions, this is a feature worth noting.
Food powder filtration and impurity removal may seem like just one step in the production line – but they directly affect the taste, quality, and food safety of the final product. Gaofu Machinery's filtration sieve – with its high‑precision filtration down to 400 mesh, easy screen changes and simple operation, compact size for flexible placement, and high screening and filtration efficiency with wide applicability – provides food processors with a fine filtration solution from powders to slurries.
Founded in the 1980s, Gaofu Machinery has over 40 years of experience in screening. The filtration sieve covers a screening particle size range of 0.038‑5 mm , with filtration precision up to 400 mesh , operating noise ≤85 dB , and a normal service life of 15‑20 years. With its easy screen changes, simple operation, and convenient cleaning, it has earned the trust and positive feedback of over 10,000 customers worldwide across the food, pharmaceutical, chemical, metallurgical, and other industries.
