    Why Sottoriva LYRA Commercial Food Equipment product does not have a constant weight?
    • V
      Veronica WareAug 7, 2025
      If your Sottoriva Commercial Food Equipment product's weight is inconsistent, several factors could be at play. It might be that the dough is too thick for the star cylinders to cut properly; in this case, try filling the hopper with smaller dough amounts, maintaining a minimum of 2/3 kg. Another cause might be related to the small dividing pistons not stroking correctly, requiring cleaning. Alternatively, there could be insufficient pressure on the dough from the breaking piston, so ensure the rectangular breaking piston moves freely, cleaning it if necessary. Lastly, a dirty photocell and reflector in the supply hopper can cause issues, so clean them carefully.

    What to do if Sottoriva LYRA Commercial Food Equipment product does not come out properly rounded?
    • F

      If the product from your Sottoriva Commercial Food Equipment isn't rounding correctly, consider these points: * The rounding chamber may be incorrectly regulated, needing adjustment of the pistons. * There might be excessive or insufficient flouring; adjust the flour delivery rate. * The rounding conveyor could not be gripping the dough properly, requiring cleaning. * Rounding speed may be too low or too high; adjust the speed using the touch screen.

    How to fix Sottoriva Commercial Food Equipment when the balls do not come out aligned?
    • C
      Christopher MercadoAug 26, 2025
      If the balls aren't aligned as they exit your Sottoriva Commercial Food Equipment, it's possible that the dividing conveyors aren't being driven evenly. You should check the tension in the conveyors and increase it if they are slipping.
