The vacuum suction hopper is a transfer station in the process of vacuum raw material conveying and is one of the important components of raw material conveying. The correct selection of the suction hopper is an important factor in ensuring stable feeding.

The vacuum suction hopper has a capacity ranging from 3L-100L and is mainly divided into four series: ordinary stainless steel (external electrostatic spraying), stainless steel polishing, optical grade (all stainless steel), and sanitary grade (all stainless steel polishing, sanitary sealing material). Each series can be equipped with visual reserve (divided into large, medium, and small reserve quantities) glass tubes, check valves, shut-off valves, etc. The control modes include mechanical, induction level (Honeywell electric eye in the United States), and proximity switch (magnetic spring switch).
