A batter production device for producing a batter by mixing a fresh liquid and a pulverulent material to form a batter for coating a food product, comprising: • a container for receiving a predetermined amount of fresh liquid and a dosage of pulverulent material, • an agitator that is installed in or on the container and immersed into the container for mixing the fresh liquid and the pulverulent material to form the batter, • a liquid supply system for supplying the predetermined amount of fresh liquid to the container, comprising: ∘ an upstream supply tube for the supply of fresh liquid, ∘ a downstream main tube with a first outlet and associated main valve for receiving fresh liquid from the supply tube and discharging into the container, ∘ a flow meter for determining the amount of fresh liquid that flows by, • a control system in connection with the main valve and the flow meter and to which the predetermined amount of fresh liquid is inputted, which control system is operable to fill the container with the predetermined amount of fresh liquid, characterized in that the liquid supply system further comprises a downstream auxiliary tube with a second outlet and associated auxiliary valve also receiving fresh liquid from the supply tube and discharging into the container, wherein the auxiliary tube has a smaller cross-section than the main tube and/or wherein the auxiliary valve has a smaller discharge cross-section than the main valve, so that - in use - fresh liquid is discharged from the first outlet at a first volumetric flow rate and from the second outlet at a second volumetric flow rate which is smaller than the first volumetric flow rate, the auxiliary valve also being in connection with the control system, and wherein the main valve and auxiliary valve are operable independent from each other, and wherein the control system is configured to cause a pre-fill of the container at least via the main tube and to cause an end-fill of the container only via the auxiliary tube. • a container for receiving a predetermined amount of fresh liquid and a dosage of pulverulent material, • an agitator that is installed in or on the container and immersed into the container for mixing the fresh liquid and the pulverulent material to form the batter, • a liquid supply system for supplying the predetermined amount of fresh liquid to the container, comprising: ∘ an upstream supply tube for the supply of fresh liquid, ∘ a downstream main tube with a first outlet and associated main valve for receiving fresh liquid from the supply tube and discharging into the container, ∘ a flow meter for determining the amount of fresh liquid that flows by, ∘ an upstream supply tube for the supply of fresh liquid, ∘ a downstream main tube with a first outlet and associated main valve for receiving fresh liquid from the supply tube and discharging into the container, ∘ a flow meter for determining the amount of fresh liquid that flows by, • a control system in connection with the main valve and the flow meter and to which the predetermined amount of fresh liquid is inputted, which control system is operable to fill the container with the predetermined amount of fresh liquid, characterized in that the liquid supply system further comprises a downstream auxiliary tube with a second outlet and associated auxiliary valve also receiving fresh liquid from the supply tube and discharging into the container, wherein the auxiliary tube has a smaller cross-section than the main tube and/or wherein the auxiliary valve has a smaller discharge cross-section than the main valve, so that - in use - fresh liquid is discharged from the first outlet at a first volumetric flow rate and from the second outlet at a second volumetric flow rate which is smaller than the first volumetric flow rate, the auxiliary valve also being in connection with the control system, and wherein the main valve and auxiliary valve are operable independent from each other, and wherein the control system is configured to cause a pre-fill of the container at least via the main tube and to cause an end-fill of the container only via the auxiliary tube.
