Description

Technical Field

[0001] The invention relates to the field of general crushing, grinding or pulverizing, and in particular to a device and method for removing impurities from refined bear bile powder. Background Art

[0002] The freeze-drying technology of bear bile powder is compared with the drying technology. The drying process of fresh bile is an important influencing factor for the difference in appearance and quality of bear bile powder. At present, the main methods for drying bear bile are drying technology and freeze-drying technology. The drying method is to use an oven or dryer to dry at a temperature between 40℃ and 50℃. This method is simple to operate and low in cost, and is adopted by most companies. However, its disadvantage is that due to the high temperature, the effective ingredients such as taurine ursodeoxycholic acid are oxidized and lost, the appearance color is poor, and iron bile or cauliflower bile is formed. The freeze-drying machine for bear bile powder adopts freezing and vacuum drying technology. First, the bear bile liquid is placed on the freeze dryer partition and frozen into a solid state by lowering the temperature; then, heat is applied in a vacuum environment to sublimate the water directly from the solid state to the gas state, and then freeze-dried bear bile powder is obtained. This process retains the active ingredients of bear bile and ensures its medicinal effect. However, the existing bear bile powder is prone to impurities in the original liquid during the process of making powder, which is difficult to handle after being mixed in the internal freeze-dried powder.

[0003] Regarding the above-mentioned refined bear bile powder impurity removal and purification device and method, a patent number of CN201610970620.7 was found through searching. The invention discloses a purification device for traditional Chinese medicine that is convenient for taking materials, including a base, a support frame and a crushing disk. The base is provided with a support frame at the upper end, a crushing disk is clamped at the top of the support frame, a crushing knife is provided in the crushing disk, a left material door and a right material door are hinged on the left and right sides of the crushing disk, and a connecting pipe is provided at the lower end of the crushing disk, which is connected to the connecting pipe. A filter screen is provided at the bottom of the connected crushing disc, the lower end of the connecting pipe is connected to the abrasive disc, a transfer block is provided in the abrasive disc, connecting blocks are arranged in an array on the outside of the transfer block, the outside of the connecting block is connected to the abrasive roller through a spring column, the abrasive disc is composed of an upper abrasive disc and a lower abrasive disc, the lower abrasive disc is one third of the volume of the upper abrasive disc, a connecting disc is provided at the junction of the lower abrasive disc and the upper abrasive disc, and support rods are symmetrically provided on the left and right sides of the connecting disc of the lower abrasive disc. The structure of the invention is simple and reasonable, eliminates the problem of inconvenience in taking materials in the existing device, and facilitates the taking of materials in the device.

[0004] The purification equipment for traditional Chinese medicine is used for filtering after crushing. After filtering, due to the different sizes of particles produced during crushing, larger particles are easily gathered together due to their number, resulting in particles being blocked in the filtering structure. Under the continuous filtering operation, it is easy for the later materials to no longer pass through the filtration due to the blocked particles. At the same time, when the bear bile is freeze-dried, some impurities will be mixed in. When the freeze-dried blocks are powdered in the later stage, the impurities mixed in the inside are difficult to handle, affecting the quality of the freeze-dried powder. Summary of the invention
