A vacuum conveyor for conveying a granulate and/or powdered material, the conveyor comprising:

• a main body having an upper end and a lower end;
• a cavity inside the main body, said cavity comprising an opening arranged at the lower end of the main body;
• a valve arranged at the opening positionable between an open position allowing a flow of granulate and/or powdered material out from the cavity through said opening and a sealing position sealing said opening;
• an inlet arranged at the upper end of the main body forming an inlet passage into the cavity;
• a venturi inside the main body at a position being distinct from the cavity, said venturi comprising a venturi inlet and a venturi outlet, wherein said venturi outlet is at a position being distinct from said cavity and said opening;
• and
• a suction channel fluidly connecting the throat of the venturi with the interior of the cavity at a position at or above the inlet;
• wherein said valve is an electro-mechanical valve and the conveyor further comprises a control unit configured for controlling said electro-mechanical valve and, wherein said control unit is further configured to exchange control signal(s) and/or data through a connector.
