A GMP Vibro Sifter (also known as a vibratory sifter, vibro screen, or gyratory sifter) is a specialized vibrating sieving machine designed to comply with Good Manufacturing Practices (GMP) standards. It is widely used in pharmaceutical, food, chemical, and cosmetic industries for screening, grading, and separating powders, granules, and liquids based on particle size.
The “GMP” designation means the machine is built for hygienic processing:
-
Contact parts are typically made of stainless steel 316 (SS 316).
-
Non-contact parts use SS 304.
-
Features include easy cleaning, no crevices for contamination, FDA-approved materials, and smooth polished surfaces.
This ensures product purity, prevents cross-contamination, and meets regulatory requirements (e.g., FDA, WHO-GMP).

Key Applications
-
Pharmaceuticals: Sieving active pharmaceutical ingredients (APIs), excipients, granules for tablets/capsules; removing lumps, oversize particles, or impurities.
-
Food & Chemicals: Grading powders, de-dusting, and solid-liquid separation.
-
Ensures uniform particle size for consistent product quality (e.g., better flow in tablet compression).

Process Operation of Vibro Sifter Vibratory Sieve
This vibrating energy screen is unit consisting of circular pre-tensioned screen mounted on the frame along with vibrating motor. The vibrating motor imparts three plane vibrations to the screen due to revolving eccentric weights. Total assembly is mounted on suitable springs so that it becomes a independent body which vibrates without parting any vibrations to the foundations.
