ADVANTAGE - The homogenizer: recycles water resources; saves energy and is environmentally friendly; cuts and grinds the raw materials by grinding and cutting mechanism to prevent the raw materials from blocking or damaging the channels, thus improving the practicality. DETAILED DESCRIPTION - High-pressure homogenizer comprises a base (1), a cavity (2), a high-pressure pump (3), a feed pipe (4), a raw material chamber (5), a discharge pipe and a processor. The cavity is fixed on the base. The high-pressure pump is fixed above the cavity. The one end of the feed pipe is connected with the upper part of the cavity through a high-pressure pump. The other end of the feed pipe is connected with the lower part of the raw material chamber. A first valve is provided at one end of the feed pipe near the raw material chamber. The lower part of the cavity is connected with the discharge pipe. The processor is fixed outside the cavity. The cavity is provided with a Y-shaped interactive channel. A water conveying mechanism is provided on the base, a grinding and cutting mechanism is provided in the raw material chamber and the processor. There is a PLC inside, and the first valve is electrically connected to the PLC. The water conveying mechanism includes a water tank, a water pump, a cooling pipe, a return pipe and a cleaning pipe. A water-cooling zone is provided in the cavity. The water cooling area is arranged around the Y-shaped interactive channel and the water tank is fixed on the base. The water pump is fixed on the water tank. The one end of the cooling pipe is connected with the bottom of the water tank through a water pump. The other end of the cooling pipe is connected with the lower part of the water cooling zone. The two ends of the return pipe is connected with the upper part of the water cooling zone and the water tank. The one end of the cleaning pipe is connected at the bottom of the water tank. The other end of the cleaning pipe is connected with the raw material chamber. A second valve is provided at one end of the cleaning pipe near the raw material chamber. The water pump and the second valve are both electrically connected to the PLC. The grinding and cutting mechanism includes a motor, a rotating shaft, a first grinding cone, at least two second grinding cones and at least two blades. The motor is fixed on the top in the raw material chamber. The motor is drivingly connected to the first grinding cone through a rotating shaft. The second grinding cone meshes with the first grinding cone. The second grinding cone is hinged to the inner wall of the raw material chamber. The blades are evenly distributed on the outer periphery of the rotating shaft in the circumferential direction. The motor is electrically connected to the PLC.
