Laboratory Vibro Sifter

Description

Laboratory Vibro Sifter (also known as a lab vibro sifter, R&D vibro sifter, or small-scale vibratory sieving machine) is a compact vibrating screening device designed for small-batch processing in research and development settings. It is commonly used in pharmaceutical, chemical, food, and other laboratories to separate, grade, and sieve powders, granules, or mixtures based on particle size. Unlike larger industrial vibro sifters, lab models are smaller (often 8-12 inches in diameter), portable, and suitable for processing limited quantities of material while maintaining high precision and compliance with standards like cGMP (current Good Manufacturing Practice).

Working Principle of Laboratory 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 Uses of Laboratory Vibro Sifter

Particle size grading and separation: Sorting powders into uniform fractions.

Removal of impurities or lumps: De-lumping stored materials.

Solid-solid or solid-liquid separation: Screening small batches of pharmaceutical ingredients, chemicals, or food samples.

Quality control and R&D testing: Ensuring consistency in drug formulations, excipients, or experimental materials.

Ideal for small-scale production in pharma labs, colleges, or pilot plants.

Key Features of Laboratory 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.

Portable & Movable — Lightweight, easy-to-move construction (often with castor wheels) perfect for lab environments.

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 Laboratory Vibro Sifter

What is a Laboratory Vibro Sifter?

A Laboratory Vibro Sifter (also known as Lab Vibro Sifter, R&D Vibro Sifter, or Lab Scale Vibratory Sifter) is a compact, portable vibrating screening machine designed for small-batch processing in research and development laboratories. It is used for sieving, grading, separating, and de-lumping powders, granules, and liquids based on particle size while removing contaminants. It is cGMP-compliant and ideal for pharmaceutical, biotech, nutraceutical, and cosmetic R&D applications.

How does the Laboratory 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 larger 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 Laboratory Vibro Sifter?

Compact GMP model with SS 304/SS 316 contact parts.
Dust-free operation with lid and silicon sealing.
Easy assembly/disassembly for quick cleaning and screen changeover.
Portable and movable design with low operating & maintenance cost.
Spring-mounted vibro motor for reduced power consumption and vibration isolation.
Long screen life, low noise, IQ/OQ documentation, and optional PLC with HMI.

What are the available models and capacities?

The Laboratory Vibro Sifter is available in the following models:

AVS-20: 20–70 kg/hr output, 20″ (335 mm) diameter, 0.25 HP motor
AVS-24: 20–140 kg/hr output, 24″ (520 mm) diameter, 0.25 HP motor

It is also offered in larger diameters (30″, 36″, 48″, 60″) as per specific requirements.

Which industries use the Laboratory Vibro Sifter?

It is primarily used in the Pharmaceutical, Biotech, Ayurvedic, Herbal, Nutraceutical, and Cosmetic industries for R&D, pilot batch, quality control, and small-scale production. It is also suitable for Food, Chemical, and other sectors requiring precise particle size separation and contamination-free screening.
