Embodiment 1

[0036] Embodiment 1: a kind of process of recovering the mother liquor of the extract of Sala chinensis, comprises the following steps:

[0037] Ingredients: Take 2.4t of the mother liquor of the extract of the sage bark and add it to a stirring tank, add hot water at 90°C, the amount of hot water is 6 times that of the mother solution of the extract of the sage seedlings, and stir for 5 minutes at a stirring speed of 30r / min , to obtain a mixture;

[0038] Filtration: filter the mixture through a disc centrifuge with a rotation speed of 7000r / min and a filtration flow rate of 2t / h to obtain the filtrate;

[0039] Upper adsorption column: The macroporous adsorption resin filled in the adsorption column is D101. Before the filtrate is applied to the column, it is recoiled with water until water is discharged from the upper outlet, and then flushed with water for 35 minutes. The flow rate of water washing: 0.4m per ton of resin 3 / h; put the filtrate on the column, the flow rat...

Embodiment 2

[0044] Embodiment 2: a kind of process of recovering the mother liquor of the extract of Sala husk, comprising the following steps:

[0045] Ingredients: Take 2.4t of the mother liquor of the extract of the sage bark and add it to a stirring tank, add hot water at 95°C, the amount of hot water is 4.5 times that of the mother solution of the extract of the sage seedlings, and stir for 5 minutes at a stirring speed of 30r / min , to obtain a mixture;

[0046] Filtration: filter the mixture through a disc centrifuge with a rotation speed of 9000r / min and a filtration flow rate of 3.5t / h to obtain the filtrate;

[0047] Upper adsorption column: The macroporous adsorption resin filled in the adsorption column is NKA-9. Before the filtrate is applied to the column, it is recoiled with water until water is discharged from the upper outlet, and then flushed with water for 20 minutes. The flow rate of water washing: 0.7m per ton of resin 3 / h; put the filtrate on the column, the flow ra...

Embodiment 3

[0052] Embodiment 3: a kind of recovery process of the mother liquor of the extract of Sala chinensis, comprises the following steps:

[0053] Ingredients: Take 2.4t of the mother liquor of the extract of the sage bark and add it to a stirring tank, add hot water at 95°C, the amount of hot water is 5 times that of the mother solution of the extract of the sage seedlings, and stir for 5 minutes at a stirring speed of 30r / min , to obtain a mixture;

[0054] Filtration: filter the mixture through a disc centrifuge with a flow rate of 3t / h to obtain the filtrate;

[0055] Upper adsorption column: The macroporous adsorption resin filled in the adsorption column is LX-60. Before the filtrate is applied to the column, it is recoiled with water until water is discharged from the upper outlet, and then flushed with water for 30 minutes. The flow rate of water washing: 0.5m per ton of resin 3 / h; put the filtrate on the column, the flow rate of the filtrate on the column: 0.4m per ton ...

Abstract

The present invention relates to the field of aesculus chinensis fruit peel extract production and particularly discloses a recovery technology of aesculus chinensis fruit peel extract mother liquid.The recovery technology of aesculus chinensis fruit peel extract mother liquid comprises the following steps: material mixing: taking aesculus chinensis fruit peel extract mother liquid and dissolvingthe mother liquid with hot water at 90-95 DEG C to obtain a mixed solution; filtering; adsorption column passing; washing with water; desorption; concentration: performing ultrafiltration and reverseosmosis on a desorption solution, and concentrating the desorption solution until a sugar degree is greater than or equal to 32 to obtain a concentrated solution; and cooling crystallization. The recovery technology can be used for recovering the aesculus chinensis fruit peel extract mother liquid and has an advantage of improving yield of an effective component of aesculin.

Description

technical field [0001] The present application relates to the production field of the extract of saffron bark, more specifically, it relates to a process for recovering the mother liquor of the extract of saffron bark. Background technique [0002] Sala seed bark extract is the peel extract of Aesculus aesculus, which has the functions of anti-tissue edema, reducing vascular permeability, preventing water accumulation in tissues, and quickly eliminating the heavy feeling and pressure caused by local edema. [0003] The production of Sala Seed Bark Extract is mainly to extract the active ingredient auricine. Generally, after the Sala Seed Bark is broken, the mother liquor is obtained through dissolution, extraction, and concentration. The crystallized product of the mother liquor is the Sala Seed Bark Extract. [0004] In the prior art, most of the extracts from the bark of Sala chinensis are extracted by heat reflux of ethanol in the industrial production. After obtaining t...
