Example Embodiment

[0084] Example 1:

[0085] like figure 1 Among them, a kind of extracting method of natural borneol, comprises the following steps:

[0086] 1. Drying: air-dry the collected camphor leaves and branches; preferably, when drying, use grid-type stacking and vibration air-drying to control the moisture content of the raw materials at 10-25%. Further preferably, the moisture content of raw materials is controlled at 15-20%. Further preferred control raw material water content is about 18%. The moisture content of the collected fresh camphor tree branches and leaves is about 48-52%. The moisture content of the dried raw materials is too high, because there are more volatiles in it, which makes it difficult to purify the natural borneol in the later stage; while the moisture content is too low, there are some Natural borneol will also volatilize, reducing the yield. In the preferred solution of the present invention, the air-drying time is shortened by using grid-type stacking vi...

[0093] Example 2:

[0094] like figure 1 Among them, another optional technological process is, a kind of extraction method of natural borneol, comprises the following steps:

[0095] One, drying, the camphor leaves and camphor branches collected are air-dried;

[0096] 2. Coarse crushing, sending the dry raw materials into the chopping device for chopping;

[0097] 3. Sorting, sending the chopped raw materials into the winnowing device to sort out branches and leaves;

[0098] Four, finely crushed, adopt different equipment finely according to the raw material of sorting, wherein branch adopts hammer mill to pulverize, and particle size crosses 20 mesh sieves; Leaves adopt the mode of chopping to finely crush; Above-mentioned steps are identical with embodiment 1.

[0099] Five, distillation condensation,

[0100]Different from Example 1, an extraction process is added in this example. Extract the semi-finished branch raw material and semi-finished leaf raw material with...

Abstract

An extraction method of natural borneol includes drying; crushing; sorting, to be more specific, sending crushed raw materials into a winnowing device for sorting out branches and leaves; fine crushing; and distillation condensation; and the natural borneol is obtained by the above steps. Extraction equipment of the natural borneol includes a pretreatment device, the pretreatment device comprises a crushing device, the pretreatment device is connected with the winnowing device through a wind delivery device, the winnowing device is provided with at least two discharging ports, a branch discharge port is connected with a hammer mill, a leaf discharge port is connected with a leaf crushing device; the hammer mill and the leaf crushing device are respectively connected with an extraction device or a distillation device by a conveying device. The extraction method and equipment have the advantages of improvement of production efficiency, improvement of the yield of large-scale industrialized production and reduction of energy consumption.

Description

technical field [0001] The invention relates to the field of natural borneol production, in particular to a method and equipment for extracting natural borneol from plants such as borneol or borneol produced in Hubei. Background technique [0002] Natural borneol ( Borneolum ) formerly known as dipterocarp, also known as natural d-borneol. At present, the natural borneol produced in my country is mainly extracted from the branches and leaves of Cinnam omum camphora (L. ) Presl], and refined. It does not contain isoborneol which is harmful to human body , its medicinal effect is far superior to synthetic borneol and natural L-borneol. The current commonly used extraction method is to put borneol camphor leaves in the material liquid tank, add water to boil or feed water vapor in the distillation tank, and use steam distillation to distill, and the volatile oil and water vapor in the camphor tree branches and leaves are steamed out together. Enter the condenser tank through t...
