Use of Vacuum Receivers
Vacuum Receivers are an integral part of any Central Plastics Conveying System. They are often referred to as Vacuum Chambers or Vacuum Stations or just Stations. It doesn’t really matter how many Vacuum Receivers or “stations” there are in a system.
There could be one or there could be 200. As long as one or more central vacuum pumps are used to provide vacuum to transfer plastics, a Vacuum Receiver is used instead of a Vacuum loader. The Plastics Conveying Central Control is programmed by the processor to determine the load and dump times as well as the number of blowback blasts included in each sequence – if the blowback option is included. Vacuum Receivers are typically used in a Central Plastics Conveying Systems to transfer plastic pellets, regrind or powders from a material source to destinations like Surge Bins, Drying Hoppers, Blender Bins or directly to the throat of a processing machine. So, some are called Powder Receivers and others are called Machine-Mount Receivers. The ebb and flow of vacuum to draw resin through the material lines into the Vacuum Receiver is controlled by either a Station T valve or an “external fill valve” built into the lid of the Vacuum Receiver.
