Tea Packaging Quality Improved with Vacuum Conveying Upgrades

In an ongoing project to improve processes whenever and wherever it can, a global manufacturer of private label retail, food service and specialty brand teas, purchased an extension conveyor system to improve efficiency and ergonomics. Prior to implementing the extension conveyor, a vacuum conveyor system transferred raw materials into portable silos that workers rolled from one production machine to the next.

Paper Machine Vacuum Systems: Liquid Rings vs. Blowers

A paper machine carefully removes water from the paper sheet. Some of this water removal is done by passing air through the sheet, thus moving the water from the sheet to the wire. Air is moved by creating a pressure differential across the sheet. This is normally done by putting the sheet on a wire and then putting a box under the wire and then evacuating the air from the box. The resistance of the air movement through the sheet and wire causes the pressure drop from the machine room to the box. 

Aeration Blower Control Strategies

Real world blower applications rarely operate at steady state design conditions. There are a variety of reasons for this. Designs usually include a margin of safety to accommodate unforeseen conditions. Typically, the process demand itself is variable, requiring a corresponding ability to modulate the blower flowrate.

Case Studies in Dry vs. Wet Vacuum Pumps

We present a few case studies derived on real-world application examples, where various vacuum technologies may be suitable solutions. Each case is generalized enough that the knowledge is applicable across multiple specific applications.
