Embodiment 1

[0035] ①Pick the leaves of 1000kg of camphor tree, and crush the leaves of camphor tree into 2-3cm.

[0036] ②The crushed leaves are transported into the extraction tank 1 from the feed port 2, and vacuum extraction is carried out. If the ratio is 450 and the vacuum degree is 0.09Mpa, the extraction temperature is 40.5°C).

[0037] ③Condensate and collect the vapor volatilized from the air outlet 3, and use the low-temperature water of 6-10 degrees as the cooling water of the condenser 4.

[0038] ④Open the water vapor inlet 13, and pour water vapor into the extraction tank 1, and the water vapor temperature is less than or equal to 105 degrees.

[0039] ⑤ The vapor volatilized from the air outlet 3 is condensed and collected, and the cooling water of the condensation separation system 15 adopts low-temperature water of 30 degrees.

[0040] After the extraction, the pure dew collected in the collection tank 5 (ie, camphor oil) is about 150kg+200kg=350kg, and the sampling is ...

Abstract

The invention discloses an extraction method for improving the yield of cinnamomum longepaniculatum oil, which comprises the following steps: (1) vacuum extraction: carrying out vacuum extraction on picked cinnamomum longepaniculatum fresh leaves in an extraction tank at the extraction temperature / vacuum degree ratio of 430-3000 and the extraction temperature lt; 100 DEG C; (2) water vapor extraction: continuously performing water vapor extraction on the oil camphor tree leaves subjected to vacuum extraction in the extraction tank; and (3) combining extracting solutions. The fragrance of the cinnamomum longepaniculatum oil is basically the same as that of fresh cinnamomum longepaniculatum leaves, after the cinnamomum longepaniculatum oil is smeared to the skin, the absorptivity is good, and the content of heat-sensitive components in the cinnamomum longepaniculatum oil is effectively increased.

Description

technical field [0001] The application relates to an extraction method for improving the yield of camphor oil, camphor oil, a fragrance, and a cosmetic. Background technique [0002] Yibin belongs to the mid-subtropical monsoon climate zone. The climate is warm and humid, with plenty of sunshine. The annual average temperature is 18 degrees Celsius, the sunshine is 1100 hours, and the rainfall is 1200 mm. The soil is purple soil and mountain yellow soil developed from the parent rock of the Cretaceous Jiaguan Formation. It is very suitable for the growth and development of camphor trees. As far back as the Han Dynasty, there are records of "Jiangxi bamboo, Jiangnan camphor, northern chestnut, Shandong mulberry". In 1985, "Contemporary Chinese Forestry" recorded that in the southwest forest area, there are many broad-leaved tree species in the Minjiang River Basin, and the widely distributed rare tree species such as nanmu and camphor. In 1974, according to the research and ...
