Embodiment 1

[0017] A device for crudely extracting natural borneol from borneol camphor, such as figure 1 As shown, it includes an extraction tank 1, a first valve 2, a No. 1 condenser 3, a No. 2 condenser 4, an oil-water separator 5, a gas-water separator 6, a No. 3 condenser 7 and a receiver 8. The extraction tank 1 is used to store the pulverized borneol camphor raw materials. A sight glass is arranged on the top of the extraction tank 1 for observing the extraction tank 1. Steam coils are distributed in the extraction tank 1 for heating the inside of the tank. , a heating jacket is provided outside the extraction tank 1, a material outlet is provided at the bottom of the extraction tank 1, and a steam outlet pipe is provided at the top of the extraction tank 1, and the steam outlet pipe is respectively connected with the oil-water separator 5 and the gas-water separator through pipelines. 6, a second valve 9 is provided on the pipeline connected to the gas-water separator 6, and a fir...

Embodiment 2

[0022] The method for crudely extracting natural borneol from borneol camphor is the device used in Example 1, utilizing high-pressure steam and the properties of natural borneol, and using high-pressure superheated steam to directly act on branches and leaves at 180°C. Since the boiling point of natural borneol is about 212°C, the natural borneol can be vaporized and sublimated. In a highly sealed state, condensate and crystallize through a special condenser to extract natural borneol. The specific process includes the following steps:

[0023] 1) Crush the branches and leaves of borneol camphor, the length of the crushed particles should not exceed 10cm; preferably 3-5cm.

[0024] 2) Add the crushed borneol camphor branches and leaves to the extraction tank, use high-pressure superheated steam to directly act on the branches and leaves, control the temperature at 180°C, and extract for 35-40 minutes;

[0025] 3) Use a condenser to condense the gasified natural borneol to c...

Abstract

The invention discloses a method for coarsely extracting natural borneol from cinnamomum camphora. The method for coarsely extracting the natural borneol from the cinnamomum camphora includes steps that 1) smashing cinnamomum camphora branches and leaves, wherein the granule length is less than or equal to 10 centimeters after smashing; 2) adding the smashed cinnamomum camphora branches and leaves to an extracting tank, using high-pressure super-heated steam to directly act on the branches and leaves, controlling the temperature to guarantee the vaporization sublimation for the natural borneol in the cinnamomum camphora, and extracting for 35 to 40 minutes; 3) using a condenser to condense the gasified natural borneol, and gathering. The method for coarsely extracting the natural borneol from the cinnamomum camphora enables the extraction time to be shortened by a half, enables the yield to be improved by 10% and enables the energy consumption to be lowered by 65%, the waste water emission can be reduced by 99% through using steam, and the domestic production capacity technology is amplified by 20 times.

Description
