The liquid feed feeding system includes a mixing tank, a conveying system, and a control system. An inlet and a water inlet I are set at the top of the mixing tank; a mixing blade is mounted on the stirrer rod inside the mixing tank; the mixing tank includes an external heating layer, which is internally filled with water, and a heating pipe is set at the bottom of the external heating layer; a temperature sensor is set within the external heating layer, and an inlet II, an exhaust port, a drain port, and a liquid level observation port are set above the external heating layer; a weighing sensor is set at the bottom of the mixing tank; a return pipe connecting to the top of the mixing tank is set at the outlet of the feeding pump, and a valve is set on the return pipe; an exhaust valve is set at the top of the mixing tank; a sealing cover is set at the feeding inlet. This utility model can ferment wet feed and operates reliably with no pollution.

A liquid feed feeding system comprising a mixing tank, a conveying system, and a control system. The mixing tank is equipped with an inlet and water inlet I at the top; a mixing blade mounted on a stirrer rod is located inside the mixing tank. The conveying system includes conveying pipes and a discharge end, with the mixing tank's outlet connected to the conveying pipes via a feeding pump. The distinguishing feature is that the mixing tank has an external heating layer, which contains water and is fitted with a heating pipe at the bottom. A temperature sensor is positioned within the external heating layer, and an inlet II, exhaust outlet, drain outlet, and liquid level observation port are set on the external heating layer. A weighing sensor is located at the bottom of the mixing tank. The temperature sensor, weighing sensor, and heating pipe are connected to the control system. A return pipe connecting to the top of the mixing tank is set at the outlet of the feeding pump, equipped with a valve; an air release valve is set at the top of the mixing tank; and a sealing cover is installed at the feed inlet.
