A food grade vibro sifter screens dry food ingredients to remove lumps, oversize particles and foreign matter, and to grade materials such as flour, sugar, salt, spices and starch. Sterial Machinery manufactures its vibro sifter for the food industry with SS 316 contact parts and screens, silicone-sealed sieves and smooth surfaces that are simple to wash and inspect.
Typical Food Applications
| Material | What the sifter does |
|---|---|
| Wheat flour, maida, besan | Removes lumps, bran pieces and foreign particles before mixing or packing |
| Sugar and icing sugar | Grades crystals; breaks up caked sugar |
| Spices and masala blends | Separates coarse fibre and grades powder fineness |
| Salt | Grades crystal size, removes lumps |
| Starch, custard and corn flour | Fine sifting for uniform texture |
| Milk powder, whey, premixes | Check screening before filling |
| Tea, coffee and cocoa powder | Grading and dust separation |
| Grains and seeds | Scalping and grading by size |
Why Stainless Steel Matters in Food Sifting
Food plants clean frequently and handle salty, acidic or oily materials. Stainless steel contact parts resist corrosion and can be washed without damaging the surface. Silicone-sealed sieves avoid lead and keep the screen seal tight. For more on the material choice, see stainless steel vibro sifter.
Check Screening Before Packing
Many food processors use a vibro sifter as the last step before filling, to make sure no oversize lumps, packaging fibres or foreign particles reach the pack. For this job a coarser screen is used, so most product passes quickly and only rejects stay on top. A vibro screening machine configured for scalping handles high throughput with a small footprint.
Selecting a Food Grade Vibro Sifter
- Output: spice units often run 20″–30″ machines; flour and sugar lines may need 36″–48″ or larger.
- Moisture and fat: oily or hygroscopic materials such as some masalas need a larger screen area and careful mesh selection to avoid blinding.
- Number of grades: to produce two sizes from one feed, choose a double deck.
- Hygiene: plan for daily dismantling and washing; keep spare screens and gaskets.

Frequently Asked Questions
Is your vibro sifter suitable for food contact?
Contact parts and screens are SS 316 and sieves are lead-free and silicone-sealed. Tell us your food safety or certification requirements so we can confirm documentation in the quotation.
Can a vibro sifter handle spices with oil content?
Yes, but oily and sticky powders can blind the screen. A larger diameter, suitable mesh and regular cleaning help. Share a sample description and we will advise.
What output can I get for flour?
Output depends on the flour type and mesh. Indicative ranges are in the specification table; we recommend a model after reviewing your requirement.
Can the same sifter be used for different food products?
Yes. Change the screen and clean the machine between products.
