INDUSTRY COMPONENT

Feed Hopper

Feed hopper for continuous screw press oil extraction machines that controls material flow into the pressing mechanism.

Component Specifications

Definition
A precision-engineered hopper component designed for continuous screw press oil extraction systems that regulates the controlled feeding of oilseeds or raw materials into the pressing chamber. It ensures consistent material flow, prevents bridging or clogging, and maintains optimal processing conditions by controlling feed rate and distribution to the screw mechanism.
Working Principle
Operates on gravity-assisted flow principles with controlled discharge mechanisms. Material enters the hopper from upstream equipment, flows downward by gravity, and is metered into the screw press through adjustable gates or feed mechanisms. The hopper maintains a buffer volume to ensure continuous operation while preventing air ingress and maintaining material integrity.
Materials
Food-grade stainless steel (AISI 304 or 316L), with optional internal coatings or liners for specific applications. Structural components may include carbon steel supports with corrosion-resistant finishes.
Technical Parameters
  • Capacity 500-5000 kg/hr
  • Inlet Diameter 300-800 mm
  • Wall Thickness 2-5 mm
  • Angle of Repose 45-60 degrees
  • Discharge Opening Adjustable 50-200 mm
  • Operating Temperature -10°C to 80°C
Standards
ISO 14159, DIN 11850
