Problems solved by technology

In the process of separating Chinese medicine components, since the Chinese medicine extract contains more solid impurities and colloids with a larger relative molecular mass, direct membrane separation technology will cause membrane pollution and reduce the service life of the membrane (membrane separation technology and Its application in the extraction and separation of traditional Chinese medicine, Wang Shaokun, etc., "World Impurities of Integrated Traditional Chinese and Western Medicine", Volume 6, Issue 12, 2011)

Embodiment 1

[0032] The donkey skin was melted into gelatin to obtain 8t donkey-hide gelatin thin gelatin, which was filtered through an 80-mesh double filter, and the filtered thin gelatin was centrifuged for 2.5 hours in a centrifuge at a speed of 4500r / min. Introduce the centrifuged dilute glue solution into the membrane separation device and start the raw material pump. The membrane in the membrane separation and concentration device is a polyamide high-temperature nanofiltration membrane with a pore size of 300 Da. After confirming that the raw material pump has a flow rate and the pipeline is unobstructed, turn on the circulation pump. After the frequency rises to 38Hz and the pressure is 0.28-0.42MPa, turn on the booster pump. After the system is stable, adjust the circulating pump frequency to 48Hz, and adjust the rubber outlet valve to reduce the glue output, increase the internal circulation volume, and make the membrane system quickly reach equilibrium. Run for 15 minutes, contro...

Embodiment 2

[0034] The kraft gelatin was used to obtain 8t yellow gelatin dilute glue solution, which was filtered through an 80-mesh double filter, and the filtered dilute glue solution was centrifuged for 2 hours in a centrifuge at a speed of 6000r / min. Introduce the centrifuged dilute glue solution into the membrane separation device and start the raw material pump. The membrane in the membrane separation and concentration device is a polyamide high-temperature nanofiltration membrane with a pore size of 500 Da. After confirming that the raw material pump has a flow rate and the pipeline is unobstructed, turn on the circulation pump. Turn on the booster pump when the frequency rises to 35Hz and the pressure is 0.28-0.42MPa. After the system is stable, adjust the circulating pump frequency to 45Hz, and adjust the glue outlet valve to reduce the glue output, increase the internal circulation, and make the membrane system quickly reach equilibrium. Run for 17 minutes, control the feed flow...

Embodiment 3

[0036] The deer antlers were melted to get 8t thin glue solution of antler glue, and the thin glue solution was filtered through an 80-mesh double filter, and the filtered thin glue solution was centrifuged for 160min in a centrifuge at a speed of 4000r / min. Introduce the centrifuged dilute glue solution into the membrane separation device, and start the raw material pump. The membrane in the membrane separation and concentration device is a polyamide high-temperature nanofiltration membrane with a pore size of 700 Da. After confirming that the raw material pump has a flow rate and the pipeline is unobstructed, turn on the circulation pump. Turn on the booster pump when the frequency rises to 36Hz and the pressure is 0.28-0.42MPa. After the system is stable, adjust the circulation pump frequency to 47Hz, and adjust the glue outlet valve to reduce the glue output, increase the internal circulation, and make the membrane system quickly reach equilibrium. Run for 18 minutes, contr...

Abstract

The invention relates to a concentration method of a gelatin traditional Chinese medicine, and particularly relates to a membrane separation concentration method of gelatin traditional Chinese medicine dilute gelatin solution. The concentration method comprises the following steps: filtering a dilute gelatin solution by a filter, centrifuging the filtered solution by a centrifuge; performing concentration separation of the centrifuged dilute gelatin solution by a membrane separation concentration device; removing foam from the gelatin solution after membrane separation concentration, further concentrating the solution by a concentration tank, and discharging the gelatin. The method of the invention has the advantages of energy saving, consumption reduction, production efficiency improvement, low noise, low labor intensity, simple equipment installation requirements, and the like when compared with conventional triple effect concentration methods.

Description

technical field [0001] The invention relates to a method for concentrating traditional Chinese medicines, in particular to a method for membrane separation and concentration of dilute Chinese medicines for colloids, and belongs to the field of concentrating traditional Chinese medicines. Background technique [0002] The concentration of gelatinous traditional Chinese medicine mainly includes steps such as filtration and centrifugation, evaporation, foam extraction, concentration, and gelation. At present, the concentration of the thin glue solution of traditional Chinese medicines generally adopts a three-effect concentration device. This device adopts the principle of evaporation for the concentration of the thin glue solution of traditional Chinese medicine glue. The water in the thin glue solution reaches the boiling point and turns into steam to separate from the glue solution, thereby obtaining a high-concentration glue solution. [0003] In order to achieve a better ...
