Description

High-pressure defoaming MVR traditional Chinese medicine concentration device

technical field

The utility model relates to a traditional Chinese medicine concentration system, in particular to a high-pressure defoaming MVR traditional Chinese medicine concentration device.

Background technique

The traditional Chinese medicine concentration method often uses a concentration kettle as the concentration equipment for the liquid medicine. This method is carried out under normal pressure conditions, the temperature of the liquid medicine is high and the heating time is long, and the active ingredients in the liquid medicine are easily decomposed and invalid. The operation of the concentration kettle consumes a large amount of raw steam, and the energy consumption of the concentration process is relatively high. In addition, traditional Chinese medicine contains a large amount of surface active ingredients such as protein, mucus and saponin. The existence of the above substances will cause a large amount of foam during the concentration process of the liquid medicine, and even cause the phenomenon of "bumping" during the concentration process of the liquid medicine, which will not only affect the quality of the medicine. Quality, also can reduce the product yield of liquid medicine.

Fig. 1 is the system schematic diagram of the utility model. A high-pressure defoaming MVR traditional Chinese medicine concentration device, characterized in that it includes a compressor 1, a heat exchanger 2, a material pump 3, a separator 4, a foam detector 5, an electromagnetic stop valve 6, a condensate tank 7, and a vacuum pump 8 . The compressor 1 is a Roots compressor, and the heat exchanger 2 is a shell-and-tube heat exchanger. The inlet of compressor 1 is connected to the top air outlet of separator 4, one outlet of compressor 1 is connected to the shell side inlet of heat exchanger 2, and the other is connected to the upper position of separator 4, and an electromagnetic cut-off is installed on this connecting pipeline Valve 6; the shell-side condensate outlet of heat exchanger 2 is connected to condensate tank 7, and the non-condensable gas exhaust port of condensate tank 7 is connected to vacuum pump 8; the outlet at the bottom of separator 4 is connected to the inlet of material pump 3.

The foam detector 5 is mounted at an upper position inside the separator.

The working principle of the utility model is as follows:

When the liquid medicine is concentrated, the secondary steam on the upper part of the separator 4 enters the compressor 1, and after being compressed by the compressor 1, the temperature and pressure of the secondary steam rises, enters the shell side of the heat exchanger 2, and heats the medicine circulated on the tube side of the heat exchanger. The condensed water of the liquid and the secondary steam enters the condensed water tank 7, and the non-condensable gas is discharged from the system through the vacuum pump 8. Under the action of the circulation pump 3, the liquid medicine circulates continuously in the circuit composed of the heat exchanger and the separator; when the foam detector 5 detects that the height of the foam layer in the separator 4 reaches the set value, the electromagnetic shut-off valve 6 is opened , the high-pressure steam at the outlet of the compressor 1 enters the foam layer in the separator 4 through the electromagnetic shut-off valve 6. In the case of a sudden change in pressure, the internal and external pressure of the foam is unbalanced, and the foam breaks rapidly.

The utility model adopts steam recompression technology to realize the recycling and utilization of heat in the process of concentrating traditional Chinese medicine. The system operates under the condition of negative pressure and low temperature, which ensures that the active components of the medicinal liquid are not lost during the concentrating process; The liquid medicine foam in the separator is defoamed, and the device has the characteristics of energy saving, stable operation and convenient operation.
