  • Publication number: 20230016783
    Abstract: A mixing unit (1) for mixing a liquid product (2) includes a tank (3) and a fluid nozzle (4) configured to inject a fluid flow (6, 7) of the liquid product (2) into the tank (3). The fluid nozzle (4) has a first outlet (20) that opens in a sideways direction (S), a second outlet (21) that opens in an upward direction (U), and a valve plug (14) configured to selectively open and close the outlets (20, 21). The mixing unit (1) is operable in a low stage operational mode (9) during which the first outlet (20) is open, the second outlet (21) is closed, and mixing occurs in a lower region (10) of the tank (3), and a high stage operational mode (11) during which the first outlet (20) is closed, the second outlet (21) is open, and mixing occurs in an upper region (12) of the tank (3).

  • Publication number: 20230011697
    Abstract: A dust collection device and method for filtering powder from powder-filled air in a food product processing system. The dust collection device includes a venturi mixer having an inlet for receiving powder-filled air, a liquid inlet for receiving liquid, and a nozzle. The nozzle is arranged to eject the liquid into a mixing zone of the venturi mixer. The powder-filled air and the liquid meet in the mixing zone to form a liquid mixture. The dust collection device includes a chamber that receives the liquid mixture from the mixing zone, a recirculation line that feeds the liquid mixture back to the liquid inlet of the venturi mixer, and an air outlet that discharges air from the chamber.
