Direct Discharge Sifter

Production Problems It Solves

Too little headroom for a long screening arrangement

Accepted powder leaves below the deck through a short vertical path.

Oversize entering a mixer with bagged ingredients

Retain lumps and larger contaminants at the mesh before the powder reaches the receiving vessel.

Where It Fits in Your Plant

Bag-emptying stations

Place the sifter below the powder intake and above the next hopper to screen flour, starch or dry additives as they enter production.

Mixer charging

Screen dry ingredients before blending when the duty is oversize removal rather than producing many graded fractions. Retained solids still need a clear removal route.

How the Direct Discharge Sifter Works

Vibration presents the feed to the mesh. Accepted material passes toward the bottom discharge, while retained oversize remains separated according to the actual outlet arrangement. The configuration must establish how retained contamination is removed.

Selection Factors

• Installation height: inlet, mesh deck and lower discharge must fit between adjoining process connections.
• Scalping duty: select the aperture for unwanted oversize rather than expecting many graded fractions.
• Oversize removal: the retained material needs an accessible collection or discharge arrangement.

Common Issues & Checks

• Reduced downward flow: inspect mesh loading and discharge restrictions below the screen.
• Contamination after screen changes: inspect gasket seating and mesh fixing before restarting.
