Powdered dietary supplements and other nutraceutical ingredients present varied screening conditions. Botanical powders, protein ingredients and mineral blends can differ in flowability, moisture sensitivity and particle size. A screening step should therefore be developed around the actual formulation and a documented separation objective.

Check the effect on the formulation

Sifting may retain coarse particles and some agglomerates, but it can also change the proportions of a blend when ingredients have different particle sizes. During trials, record the mass of each fraction and investigate whether retained material contains an intended ingredient. Do not assume a finer-looking powder has the correct composition or nutritional content.

Evaluate mesh condition and cleaning

Mesh identification, tension, integrity and installation checks help make screening conditions repeatable. Define when to inspect the screen and how to respond to damage. If metal contamination is a relevant hazard, assess additional controls appropriate to the material; a sieve should not be represented as a universal metal-removal device.

Product changeovers require attention to retained powder, seals and accessible contact surfaces. Where ingredients introduce allergen risks, establish suitable segregation, cleaning and verification procedures. A short dismantling time does not itself demonstrate effective cleaning.

Use trials to set realistic operating conditions

Compare configurations using the same feed condition and sampling method. Record moisture, aperture, feed rate, accepted fraction and any mesh blinding. Ultrasonic assistance may be considered for suitable fine-powder applications, subject to material testing and confirmation of the proposed equipment configuration.

Tianteng enquiries can include formulation handling requirements, target cut size, capacity and cleaning constraints. Suitability, contact materials and any requested certificates must be checked for the specific supply. No health benefit, elimination of all impurities or automatic compliance with dietary-supplement regulations is promised by installing screening equipment.
