This invention provides a preparing method of the Chinese traditional medicinal composition granules for treating galactophore disease. The method consists of the following steps: (1)Take tangerine leafs, radices salviae, Chinese honeylocust, cowherb seed, Chinaberry fruit and earthworm. (2)Fry the tangerine leafs, radices salviae, Chinese honeylocust, cowherb seed,, Chinaberry fruit in water separately, combine the fried liquids, filter them and have the filtered liquid concentrated. (3)Add earthworm to concentrated liquid obtained in step (2), mix it even. (4)Use 60-90% ethanol to abstract the concentrated liquid obtained in step (3), filter the abstracted liquid, reclaim ethanol and concentrate it till it forms into thick cream. (5)Add one or manifold of the following ingredients: canesugar, lactose, xylitol and tangerine sugar, add an amount of starch, starch gum, then mix them even, boil to make them into the form of granules.

The present invention relates to a method for preparing alcohol-based fracturing fluid, comprising: step S1, injecting a thickener into a preparation chamber through a first feeding port, and swelling with water in the preparation chamber; and step S2, passing through a first preset time, alternating The coupling agent passes through the second feed port, the foaming agent passes through the third feed port, the compounding agent passes through the fourth feed port, and the foam stabilizer is injected into the preparation chamber through the fifth feed port to stir and mix with the swollen thickener Alcohol-based fracturing fluid is formed; step S3, the alcohol-based fracturing fluid is injected into the detection chamber through the first pipeline, and the central control unit controls the detection chamber to be inverted several times. After the second preset time, the central control unit injects the alcohol-based fracturing fluid through The second pipeline is discharged, and the central control unit obtains the stability of the alcohol-based fracturing fluid, and determines that the alcohol-based fracturing fluid with qualified stability will be produced. In the present invention, a central control unit is set to adjust the parameters of each component so that the stability of the produced alcohol-based fracturing fluid meets the preset standard.
