Description: Material receiving and preliminary distributing component fitted at vibrating screen top section for corn starch production lines; upper structural spare for screening equipment. Mounted at screen absolute top position, interfacing with upstream feed pipe / feeding equipment. Starch powder falls into hopper from above; conical hopper body collects incoming feed and distributes material evenly onto central screen mesh surface, achieving uniform feed distribution across full mesh area and securing screening efficiency and grading precision.
Hopper body: Conical stainless steel funnel (large top, narrow bottom), manufactured by rolling and welding stainless steel sheet.
Top flange: Upper circular flange for connection to feed pipe / silo outlet.
Bottom discharge port: Small diameter outlet aligned with screen mesh centre.
Observation port: Side mounted inspection door fitted with sight glass for feed monitoring and blockage removal.
Quick release clamps: Bottom quick disconnect interfaces enabling fast disassembly and cleaning.
Reinforcing ribs: External stiffeners preventing vibration induced deformation.
Optional bridge breaking assembly: Mitigates starch bridging and feed blockage incidents.
Implements gravity feed collection and homogeneous material distribution workflow.
1. Material feeding: Starch powder drops from upstream piping / equipment into large top hopper opening.
2. Convergence & flow guidance: Conical hopper inner wall guides material downwards converging toward central discharge port.
3. Even distribution: Material discharges from bottom outlet onto screen mesh centre and spreads radially outward under screen vibration.
4. Feed flow buffering: Hopper acts as buffer chamber stabilising feed rate and suppressing abrupt feed volume fluctuations.
5. Observation & blockage clearance: Side observation port permits visual feed inspection; port can be opened to clear blockages.
Food grade construction: 304 stainless steel with polished inner surfaces complying with food hygiene standards.
Optimised cone angle design: Prevents starch adhesion and bridging for smooth material flow.
Homogeneous feed distribution: Outlet aligned with screen mesh centre guarantees even material spread over full mesh area.
Built in observation access: Side sight glass enables real time feed process monitoring.
Quick release assembly: Clamp connections simplify disassembly and sanitisation.
Corrosion resistant stainless steel build: Resists starch slurry corrosion.
Low maintenance: Ground smooth weld joints; no material accumulation dead zones, convenient batch change over cleaning.
