Solve the problems encountered in the actual use of vacuum dryer - intelligent defoaming technology
First, the technical purpose and principle In the actual use of vacuum dryers made by traditional techniques, many users of traditional Chinese medicine production enterprises often face a common problem: in Chinese medicine extracts (especially those with high sugar and vegetable oils) The material overflow phenomenon often occurs during the drying process, which not only causes great loss of materials, but also causes great trouble to the internal cleaning work of the equipment. The intelligent defoaming technology uses the micro-pressure hot air to heat the upper surface of the material, so that the surface of the material can not form a cold film, so that the water vapor formed inside the material can be smoothly discharged after being heated; at the same time, the compressed air is used to enter the negative pressure. The principle of the geometrical multiplication of the volume of the cavity forms a needle-punching effect on the foam on the surface of the material, thereby achieving the purpose of defoaming. Moreover, after the compressed air enters the tank, the airflow is rapidly expanded to form a gas flow, which is more advantageous for the vacuum pump to extract the water vapor in the tank, thereby greatly improving the drying efficiency of the equipment. Second, the technical process The compressed air is stored in a heatable gas storage bag and heated (temperature controllable), and the heated compressed air is connected to the uniform jet device in the tank through a solenoid valve, and the solenoid valve can be realized by adjusting the PLC program. The separate control of the on and off times controls the intake air volume of the compressed air to achieve intelligent control of different drying processes of different materials. The angle of the inlet of the micro-pressure hot air can be adjusted, and the flow of the hot air that is defoamed into the cylinder can be controlled according to the situation, so that the material can be spattered and the foaming of the material can be defoamed.
