Dust collection device and method for filtering powder

A food product processing system comprising:

• a dust collection device for filtering powder from powder-filled air that is drawn from a food product processing system, the dust collection device comprising:
• a venturi mixer that has an inlet for receiving the powder-filled air, a liquid inlet for receiving a liquid, a nozzle, and a housing that defines a mixing zone, wherein the nozzle is arranged to eject the liquid into the mixing zone and to create a vacuum when the liquid passes though the nozzle, such that the powder-filled air is drawn into the mixing zone where the powder-filled air and the liquid meet to form a liquid mixture of the liquid and the powder from the powder-filled air, and
• a chamber arranged to receive the liquid mixture from the mixing zone, wherein the dust collection device further comprises:
• a recirculation line arranged to draw the liquid mixture from the chamber and feed the liquid mixture to the liquid inlet of the venturi mixer, and
• an air outlet arranged to discharge air from the chamber,
• a powder handling unit connected to the dust collection device, for allowing powder-filled air to be conveyed from the powder handling unit to the dust collection device,
• an ingredient feeding unit configured to receive and feed an ingredient;
• and
• a mixing unit fluidly connected to the ingredient feeding unit and configured to mix the ingredient with a liquid, wherein
• a fluid line is connected between the chamber of the dust collection device and the mixing unit, for allowing transportation of the liquid mixture from the chamber to the mixing unit.
