Food powder filtration differs significantly from general industrial powder processing. The challenges stem from the dual nature of material properties and industry standards:
Fibrous impurities are difficult to completely remove. During harvesting, processing, storage, and transport, food raw materials may become contaminated with plant fibres, bran, packaging fibre debris, and other contaminants. These fibrous impurities are lightweight and easily airborne – on conventional filtration equipment, they are difficult to intercept effectively and can easily contaminate the finished product, affecting mouthfeel and purity.
Hard impurities compromise food safety. Food raw materials may contain stones, metal filings, hard lumps, and other contaminants. These hard impurities not only affect product mouthfeel but can also damage downstream processing equipment and even create food safety incidents.
Fine powder blinding reduces filtration efficiency. Food powders such as powdered sugar and starch have fine particles – during filtration, they readily block the filter mesh, causing filtration efficiency to decline steadily and requiring frequent stoppages for cleaning.
Gaofu's filtration sieve (filter sieve machine) uses a vibration motor as the excitation source – it is a small vibrating screening machine with high screening efficiency, low noise, and a compact design. During operation, the vibration motor generates high‑frequency, low‑amplitude vibration, creating a thin‑layer flow of material on the screen surface – effectively preventing fibrous and viscous materials from accumulating on the mesh.
The equipment is suitable for single‑layer screening and filtration in various industries, handling materials with low production volume or low impurity content. The filtration sieve features non‑blocking mesh, no powder emission, and can screen down to 400 mesh. Impurities and oversize material are automatically discharged, enabling automated operation.
Gaofu's filtration sieve offers the following core advantages for removing fibres and hard impurities from food powders:
1. High‑Precision Filtration – Fineness Assured
The filtration sieve features non‑blocking mesh and no powder emission – capable of screening down to 400 mesh. The screening particle size range covers 0.038‑5 mm. For typical food powder filtration requirements, this accuracy capability provides ample margin – effectively intercepting fibres, hard impurities, and off‑spec particles – ensuring consistent finished product fineness.
2. 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. For food processing lines requiring long‑duration continuous operation, this means higher equipment utilisation and more stable output.
3. Easy Screen Changes – Simple Operation, Convenient Cleaning
The filtration sieve features a unique screen frame design – screen changes are easy, operation is simple, and cleaning is convenient. 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.
4. 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.
5. 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 food powders or filtration of slurries, it delivers reliable results. The equipment is durably designed – suitable for any powder or viscous liquid.
6. Low‑Noise Operation – Improving the Workshop Environment
The equipment operates at ≤85 dB with ≤5 mm amplitude. For food processing plants looking to improve workshop working conditions, this is a feature worth noting.
Gaofu's filtration sieve is used in the following typical food powder filtration applications:
Fine filtration of starches and powdered sugars. Removing fibrous impurities, lumps, and hard particles from starches and powdered sugars – ensuring uniform fineness and reliable purity. The filtration sieve can screen down to 400 mesh – meeting the fine filtration requirements of starches, powdered sugars, and other food powders.
Impurity removal filtration of seasoning powders. Seasoning powders such as chilli powder, pepper powder, and Sichuan pepper powder often contain coarse fibres, seed husks, and other impurities that need to be removed through filtration. The single‑deck design of the filtration sieve effectively intercepts these impurities – ensuring seasoning powder purity.
Fibre removal from flour and rice flour. Flour and rice flour may become contaminated with bran fibres and packaging fibre debris during processing. The high‑precision filtration capability of the filtration sieve effectively removes these fibrous impurities – ensuring the purity of bakery ingredients.
Fine filtration of milk powder and protein powder. Milk powder, protein powder, and similar materials demand extremely high purity – any fine impurity can affect product quality. 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, and other liquid materials – removing solid impurities and fibres.
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.
