Problems solved by technology

Since most of the top notes will be lost during the evaporation process, the resulting essential oils will not have a good aroma
In addition, the traditional oil cold suction method or warm soaking method is rarely used due to cumbersome operation, long processing time and high labor consumption.

Example Embodiment

[0021] Example 1

[0022] A. Spread the fresh gardenias in layers on the fresh flower separating screen 5 in the cylindrical shell 4 to form the fresh flower layer 11. The lower part of the adsorption column 7 on the top of the shell 4 uses 25 grams per kilogram of fresh flowers. Place a molecular sieve layer 8, and place an activated carbon layer 9 on the molecular sieve layer 8 in an amount of 10 grams per kilogram of fresh flowers;

[0023] B. Moist air with a humidity of 75% enters from the lower part of the flower bed 11 through the air supply pipe 1, the air inlet 2 at the lower part of the housing 4, and the channel 3;

[0024] C. From the air outlet 10 on the top of the adsorption column 7 in the upper part of the shell 4, use a vacuum pump from bottom to top to pump air for 20 hours at a flow rate of 50 liters / hour, room temperature, and a vacuum degree of -18 ~ -25 mmHg , Make the moist air pass through the fresh flower layer 11, let the volatile matter in the fresh flow...

[0028] A. Spread fresh roses in layers on the fresh flower separating screen 5 in the cylindrical shell 4 to form the fresh flower layer 11. The upper part of the adsorption column 7 on the top of the shell 4 uses 35 grams per kilogram of fresh flowers. Place a molecular sieve layer 8, and place an activated carbon layer 9 on the molecular sieve layer 8 in an amount of 20 grams per kilogram of fresh flowers;

[0029] B. Moist air with a humidity of 75% enters from the lower part of the flower bed 11 through the air supply pipe 1, the air inlet 2 at the lower part of the housing 4, and the channel 3;

[0030] C. From the air outlet 10 at the top of the adsorption column 7 on the upper part of the shell 4, use a vacuum pump from bottom to top, and pump air for 26 hours at a flow rate of 40 liters / hour, room temperature, and a vacuum degree of -18~-25mmHg , Make the moist air pass through the fresh flower layer 11, let the volatile matter in the fresh flower take a...

Abstract

The invention provides a flower head perfume absorbing and extracting method and a device thereof, which takes full advantage of the character that molecular sieve only absorbs moisture, and active carbon absorbs flower head perfume component; can be used active carbon to conveniently extract the head perfume component in the flower which can volatilize easily and can lose easily, and has better floral suggestion; does not contain moisture, and can effectively take advantages of flower resource. The invention ensure the fragrance of essential oil to be pure and durable, can improves the grade of the essential product, dispenses with chemical water-removal process and equipment, and is conducive to lower investment and production cost. The invention has the advantages that using the method of the invention can obtain high-quality sweet-smelling essential oil product, but also the process is simple, the essential oil yield is high, the industrial active carbon and the molecular sieve can be recycled after being treated slightly; energy can be saved, consumption can be lowered, and production can be industrialized in large scale. The device of the invention has the advantages that the structure is simple, the investment is less, energy can be saved, and the operation and usage is more conveniently. Using the device can conveniently extract the flower head perfume component, and can fundamentally solve the problem that the prior art is difficult to extract the flower head perfume.

Description

technical field [0001] The invention relates to a flower extraction method, in particular to a flower head fragrance extraction method, which belongs to the technical field of plant extraction. Background technique [0002] The aroma of flowers is composed of many volatile components. In the process of extraction, it is very difficult to keep various ingredients intact without losing the original flavor. Especially the top fragrance ingredients are easier to volatilize and lose. The commonly used method is the solvent extraction method, that is, the flowers are extracted with petroleum ether as a solvent, and then the solvent in the extract is evaporated and removed to obtain an extract, which is dewaxed with alcohol to obtain the essential oil. Since most of the top notes will be lost in the evaporation process, the resulting essential oil has a poor fragrance. In addition, the traditional oil cold suction method or warm soaking method is rarely used due to cumbersome op...
