[0056] Among them, since the temperature of hot water will drop during the long-distance transportation, it is necessary to set the temperature control module 52 not far in front of the atomizing nozzle 70 to heat the hot water to the required temperature. In this embodiment, the temperature of the hot water should be maintained above 95 degrees Celsius. By sequentially setting the first temperature sensor 521, the second temperature sensor 522 and the electromagnetic heater 523 between the first flow meter 51 and the atomizing nozzle 70, since there is no other equipment in this section of the pipeline, only a transportation pipeline, the temperature collected by the first temperature sensor 521 to the temperature collected by the second temperature sensor 522 can be regarded as a linear change, with the first temperature sensor 521 as the starting point of the linear change, so that the water flow rate and the second temperature sensor The water temperature when the water reaches the electromagnetic heater 523 is predicted by the distance between the electromagnetic heater 522 and the electromagnetic heater 523, wherein the water flow rate is the ratio of the amount of water collected by the first flowmeter 51 per unit time to the cross-sectional area of ​​the water spraying pipeline 50, and the predicted water temperature is compared with the required hot water temperature of 95 degrees Celsius to calculate the temperature difference T. Based on the water flow rate and the length of the electromagnetic heater 523, the time required for the water of each section to completely pass through the electromagnetic heater 523 is calculated, and the heat required for the water of each section to rise by T°C is calculated, so as to accurately adjust the heating power of the electromagnetic heater 523, so as to save energy loss as much as possible under the premise of ensuring that the hot water is sprayed into the conditioner 1 from the atomizing nozzle 70 at not less than 95 degrees Celsius.

[0058] In summary, the embodiment of the present application provides a water adding system for improving the conditioning of a single-point air intake feed pellet mill. The high-temperature saturated steam output by the air source is set to enter the conditioner and is used to heat the water in the water tank. The pressure boosting pipeline, the pressure relief pipeline and the first flow meter are used to control the water pressure and flow rate of the hot water sprayed from the atomizing nozzle. The temperature control module arranged on the water spraying pipeline is used to ensure that the hot water in the water tank can maintain the temperature of the water sprayed into the conditioner when it is transported over a long distance with minimum energy consumption. The hot water is sprayed into the conditioner in the form of atomization through the atomizing nozzle, which solves the problem in the prior art that the water content in the high-temperature saturated steam is certain. When mixing different types of feed, the starch water content in the conditioner is insufficient, resulting in low starch gelatinization degree, making the powdering rate of the finished feed high, affecting the quality of the feed. At the same time, the water added in the utility model is added in the form of atomized gas, and the atomized gas is merged with the high-temperature saturated steam, so that the high-temperature saturated steam can accelerate the cooling and generally present as low-temperature steam, so that the overall steam is accelerated to be converted into water and enter the interior of the material particles, further promoting starch gelatinization. Moreover, due to the characteristic of low-temperature steam that only supplies water but does not increase the mold temperature, it can also ensure that the pressure roller in the pressing chamber of the conditioner does not slip, so that the material is fully kneaded in the pressing chamber, further reducing the powdering rate of the feed product.
