Scale Hopper Systems

Scale hoppers for the bakery, flour, sugar and dry bulk product industry.

TYPE: Silo/Hopper Discharge Vibration Aeration Equipment

MODEL: Scale Hopper Systems

Scale hoppers are typically used to measure, transport and store bulk solid materials such as flour, sugar, dextrose and starches.  They pneumatically convey product from bulk storage units to weigh batching systems on load cells.

Hopper Weigh & Batch System Features

  • Scale Hoppers
    • Scale hoppers are sized, designed and fabricated by Thomas Conveyor & Equipment for the bakery, food, chemical and plastics industry
    • Discharge slide gates, rotary valves, and controlled metering screw feeders dispense product
    • Load cells accurately weigh product as it is discharged over the process machine
  • Pneumatically Actuated Ports Control Product Flow
    • Pneumatically convey your semolina flour, wheat flour, sugar, dextrose, and starch from bulk storage to our weigh batching systems on load cells.
  • Load Cells and PLC Programming
    • A panel mounted PLC controls vacuum and/or pressure line interface capabilities.
    • We use Rice Lake load cells and PLC vendors such as A-B, Allen Bradley, Siemens, Automation Direct, and TECO
  • System Accurately Fills Large or Small Containers and Bins
  • Flow Aids
    • A Thomas Conveyor Penumatic Engineer will design the optimal equipment solution for your product(s). We will determine whether you need vibration, fluidization, live bottom bins, or aeration devices to fully unload the scale hopper.
