Pharmaceutical Vibro Sifter

Description

Pharmaceutical Vibro Sifter (also known as a vibratory sifter, vibro screen, or vibrating sieve) is a critical piece of equipment in the pharmaceutical industry used for separating, grading, and sieving powders, granules, and liquids based on particle size. It ensures product uniformity, removes oversized contaminants or lumps, and eliminates foreign particles, which is essential for maintaining drug quality, safety, and consistency in processes like tablet manufacturing, capsule filling, and granulation. Pharmaceutical Vibro Sifter are designed to meet strict pharmaceutical standards (e.g., GMP compliance), often constructed from high-grade stainless steel (SS 304 or 316L) for hygiene, easy cleaning, and corrosion resistance.

Working Principle of Pharmaceutical 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.

FAQ for Pharmaceutical Vibro Sifter

What is a Pharmaceutical Vibro Sifter?

A Pharmaceutical Vibro Sifter (also known as Vibro Screen, Vibratory Sieve, or Gyro Screen) is a GMP-compliant circular gyratory screening machine specifically designed for the pharmaceutical industry. It separates, grades, and sieves powders, granules, and liquids based on particle size, ensuring product uniformity, removing contaminants, and maintaining strict quality standards in processes like tablet manufacturing, capsule filling, and granulation.

How does the Pharmaceutical Vibro Sifter work?

The machine features a circular pre-tensioned screen mounted on a frame with a vibratory motor. The motor generates three-plane vibrations through revolving eccentric weights. The entire assembly is spring-mounted, allowing independent vibration without transferring movement to the floor. Material fed onto the screen is separated by size via multi-plane motion, with finer particles passing through and larger ones discharged outward.

What are the key features of the Pharmaceutical Vibro Sifter?

Compact GMP model with SS 304/SS 316 contact parts for hygiene and corrosion resistance.
Dust-free operation with lid and silicon sealing.
Easy assembly/disassembly for quick cleaning and screen changeover.
Spring-mounted design reduces motor HP and isolates vibrations.
Low noise, portable, long screen life, and low maintenance.
IQ/OQ documentation and optional PLC with HMI available.

What are the available models and capacities of the Pharmaceutical Vibro Sifter?

Several models are offered to suit different production needs:

AVS-20: 20–70 kg/hr (20″ dia)
AVS-24: 20–140 kg/hr (24″ dia)
AVS-30: 30–250 kg/hr (30″ dia)
AVS-36: 80–300 kg/hr (36″ dia)
AVS-48: 200–400 kg/hr (48″ dia)

Screen diameters range from 335 mm to 1220 mm with motor power from 0.25 HP to 1.5 HP.

Which industries benefit from the Pharmaceutical Vibro Sifter?

It is primarily designed for the Pharmaceutical industry but is also widely used in Biotech, Ayurvedic, Herbal, Nutraceutical, and Cosmetic sectors.
