SAN Electric Vacuum Conveyor Systems

What Is an Electric Vacuum Conveyor?

An electric vacuum conveyor is an enclosed material transfer system that uses an electrically powered vacuum pump to move powders, granules, tablets, pellets, and other bulk solids from one process point to another. By creating negative pressure inside the conveying pipeline, the system draws material from the source and transfers it efficiently to the receiving equipment.

Unlike open manual handling, it provides a controlled conveying route that can help reduce dust generation, material loss, and direct operator contact. Designed as a vacuum conveyor for powder, it can be integrated with equipment such as hoppers, silos, mixers, blenders, reactors, tablet presses, and packaging machines for efficient material transfer across pharmaceutical, food, chemical, cosmetic, plastic, and other industrial applications.

How Does an Electric Vacuum Conveyor Work?

An electric vacuum conveying system uses an electrically powered vacuum pump to create negative pressure inside the conveying line. This pressure difference draws powders, granules, and bulk solids from the source and transfers them through an enclosed pipeline to the receiving equipment.

The material is separated from the conveying air at the receiving chamber before being discharged into the next stage of production. This enclosed process makes the electric vacuum conveyor suitable for applications where controlled, hygienic, and efficient material transfer is required.

Material Pickup

The material is drawn from a hopper, drum, silo, bag dump station, or other source into the conveying pipeline.

Vacuum Generation

The electric vacuum pump generates the pressure difference required to move the material through the conveying line.

Material Transfer

The airflow carries the material through the pipeline toward the receiver, creating an enclosed powder transfer system.

Separation & Discharge

At the receiver, the product is separated from the conveying air and discharged into the downstream process equipment.

How to Select the Right Electric Vacuum Conveyor

Selecting the right electric vacuum conveyor depends on more than the required conveying capacity. Material properties, transfer distance, receiving equipment, and production requirements should all be considered.

Material Characteristics

Consider the material type, particle size, bulk density, flowability, moisture content, and product sensitivity.

Required Capacity

Determine the required transfer rate in kg/hr and whether the application requires continuous or batch conveying.

Conveying Distance

Consider the horizontal distance, vertical elevation, pipeline routing, and number of bends between the material source and receiving point.

Receiving Equipment

Identify whether the powder conveying system will feed a mixer, blender, hopper, reactor, tablet press, capsule filling machine, or packaging machine.

Construction Requirements

For pharmaceutical and food applications, consider suitable stainless-steel construction, cleanability, and hygienic requirements.

Available Utilities

The selection of an electric system should also consider the electrical supply available at the installation site.

Frequently Asked Questions

What is an electric vacuum conveyor?

An electric vacuum conveyor is a material conveying system that uses an electrically powered vacuum pump to transfer powders, granules, and other bulk solids through an enclosed conveying line.

How does an electric vacuum conveying system work?

An electric vacuum conveying system creates negative pressure inside the conveying line, drawing material from the source toward the receiving chamber. The material is then separated from the conveying air and discharged into the next process.

Can an electric vacuum conveyor be used for powder?

Yes. An electric vacuum conveyor can be used for suitable powder applications where the material characteristics and conveying requirements are compatible with the system design.

What is a vacuum conveying system used for?

A vacuum conveying system is used to transfer powders, granules, tablets, pellets, and other bulk solids between different stages of a manufacturing process.
