Food and beverage processors use screening at different stages of production, from checking incoming dry ingredients to straining liquids before further processing. A useful specification starts with the material, the separation objective and the cleaning procedure. Equipment selection should follow those requirements rather than a general description such as “food grade.”

Match the screen to the ingredient

For flour, sugar, starch and similar powders, sifting can separate oversize particles and some agglomerates according to the selected aperture. For beverage ingredients and other liquids, straining performance depends on viscosity, solids loading and the size of the material to be retained. A screen cannot identify every foreign substance or remove contaminants smaller than its effective opening.

Make hygiene part of the specification

Review product-contact metals, mesh, seals and joining details against the actual ingredient and cleaning chemicals. Access for inspection, disassembly, drainage and drying matters alongside surface finish. Allergen changeovers require a documented cleaning procedure and appropriate verification; fitting a sieve does not by itself control allergen or microbiological hazards.

Verify performance with representative material

A trial should record aperture, feed rate, moisture or temperature, accepted and rejected fractions, and cleaning observations. Changes in the recipe or feed condition may change throughput and separation results. Agree measurable acceptance criteria before comparing equipment configurations.

Tianteng lists screening equipment including ultrasonic vibrating screens and circular swing screens. Buyers can discuss an application by providing ingredient details, required cut size, target capacity and installation constraints. Product-contact construction and any supporting documentation must be confirmed for the quoted configuration.

For international projects, establish destination-market food-contact and machinery requirements before ordering. No FDA, USDA, 3-A or other approval is claimed in this article. Suitability must be assessed for the particular equipment and process.
