This embodiment is based on any of the embodiments described above, with stage 7: a detailed embodiment for calculating the water consumption in the steam injection process and adjusting the subsequent pulping.
In an exemplary embodiment of the present application, the method may further include: after the instant heating device is cooled, calculating the water consumption in the steam generation stage, calculating the subsequent required water inflow according to the total water consumption for pulping, the water amount before steam generation and the water consumption in the steam generation stage, and controlling the water pump to continuously pump the subsequent required water inflow into the cup body so as to finish water inflow.
In the exemplary embodiment of the present application, after the cooling is completed, the subsequent pulping process may be adjusted by calculating the total water consumption V1 of the steam process (i.e., the amount of water used in the steam generation stage) through a flow meter.
In the exemplary embodiment of the present application, the total amount of pulping V ═ V1+ V2+ V3; wherein V is the water inflow required by the total pulping amount, V2 is the water inflow before steam heating, and V3 is the subsequent water inflow; it is known that V3 is V-V1-V2.
In the exemplary embodiment of the present application, since the steam enters from the bottom of the cup body and contacts the slurry in the process, the steam is cooled from the gas state to the liquid state, so that most of the water consumed by the steam is liquefied in the slurry. The consistency of the pulping amount can be ensured by adjusting the water inflow of the subsequent V3 through V1.
