Embodiment 1
[0027] Embodiment 1 Get dry highland barley seedling raw material 10Kg, cut into the small section of 1~2cm or pulverize into coarse powder, use 10 times of raw material weight amount, the ethanol solution that concentration is 10%, at temperature 70 ℃, use Wuhan Huipeng pharmaceutical machinery The TQ-300 small multi-functional extraction unit produced by Equipment Co., Ltd. extracts 1 to 4 times, each time for 0.5 to 4 hours, and the extract is obtained after filtering and sedimenting through the bottom screen of the extraction tank of the multi-functional extraction unit; The SHB-C vacuum pump produced by the limited company pumps air and reduces pressure, recovers the ethanol in the extract until the alcohol concentration is less than 5%, and obtains a concentrated solution of 30Kg.
[0028] After diluting the concentrated solution with 2 times the amount of 60Kg pure water, use the GQ75 tubular centrifuge produced by Shanghai Pudong Tianben Centrifugal Machinery Co., Ltd. ...
Embodiment 2
[0033] Embodiment 2 Get dry highland barley seedling raw material 10Kg, be cut into the subsection of 1~2cm or be pulverized into coarse powder, use the ethanol solution that 20 times of raw material weight, concentration are 60%, use small-scale multifunctional extraction unit at temperature 80 ℃ Extract 1 to 4 times, each time for 0.5 to 4 hours, and obtain the extract after filtering the precipitate through the bottom screen of the extraction tank of the multifunctional extraction unit; After the concentration is less than 5%, 25Kg of concentrated solution is obtained.
[0034] After the concentrated solution is diluted with 2 times the amount of 50Kg pure water, it is centrifuged at a speed of 20000 rpm with a GQ75 type tubular centrifuge to remove suspended particulate impurities such as dust to obtain 75Kg of the centrifuge.
[0035] The centrifugate was filtered with a SJM-FHM-10 type 100nm ceramic microfiltration membrane device to obtain 100Kg of clarified liquid (40K...
Embodiment 3
[0039] Embodiment 3 Get dry highland barley seedling raw material 10Kg, cut into the segment of 1~2cm or pulverize into coarse powder, use 25 times of raw material weight amount, concentration be the ethanol solution of 40%, use TQ-300 small multi-purpose at temperature 90 ℃. The functional extraction unit extracts 1 to 4 times, each time for 0.5 to 4 hours, and the extract is obtained after filtering and sedimenting through the bottom screen of the extraction tank of the multifunctional extraction unit; After ethanol reaches the concentration of alcohol < 5%, 28Kg of concentrated solution is obtained.
[0040] After the concentrated solution is diluted with 2 times the amount of 56Kg pure water, it is centrifuged at a speed of 20000 rpm with a GQ75 type tubular centrifuge to remove suspended particulate impurities such as dust to obtain 83Kg of the centrifuge.
[0041]The centrifugal liquid adopts SJM-FHM-10 type 50nm ceramic microfiltration membrane equipment to filter, and ...
