Description

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).

Working Principle of GMP Vibro Sifter

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.

Key Features of GMP Vibro Sifter

Compact GMP Model — Designed specifically for laboratory and R&D use with a small footprint, making it ideal for limited space in pilot plants and research facilities.

Stainless Steel GMP Construction — Contact parts made from high-quality SS 304 / SS 316 for superior corrosion resistance, hygiene, and compliance with pharmaceutical standards.

Dust-Free Operation — Equipped with a lid and silicon sealing for contamination-free screening and safe handling of powders/granules.

Easy Cleaning & Maintenance — Quick assembly/disassembly design for fast screen changeover, thorough cleaning, low operating costs, and long screen life.

Vibro Motor with Spring-Mounted Design — Specially designed vibratory motor with adjustable eccentric weights; springs amplify vibrations, reduce motor HP requirement, and isolate vibrations from the floor.

Available in Multiple Sizes — Offered in diameters such as 20″, 24″, 30″, 36″, and 48″ (with options for single or multi-deck configurations).

Low Noise & Efficient — Quiet operation with high screening efficiency for small-batch processing (typically 20–140 kg/hr depending on model).

Documentation & Automation Ready — IQ/OQ documentation available; optional PLC system with Graphical User Interface (HMI).

FAQ for GMP Vibro Sifter

What is a GMP Vibro Sifter?

A GMP Vibro Sifter (also known as GMP Vibratory Sifter, Vibro Screen, or Gyratory Sifter) is a hygienic, cGMP-compliant circular vibratory screening machine designed for the pharmaceutical and allied industries. It efficiently screens, grades, and separates powders, granules, and liquids based on particle size while removing impurities and ensuring product purity. Built with SS 316 contact parts and SS 304 non-contact parts, it meets strict FDA and WHO-GMP regulatory standards.

How does the GMP Vibro Sifter work?

The machine consists of a circular pre-tensioned screen mounted on a frame with a vibratory motor. The motor imparts three-plane gyratory vibrations through revolving eccentric weights. Material fed onto the screen is separated by size — finer particles pass through to the bottom outlet, while oversize particles are discharged from the side. The entire assembly is spring-mounted, ensuring independent vibration without transmitting movement to the floor.

What are the key features of the GMP Vibro Sifter?
