Problems solved by technology

[0006] Aiming at the problems in the prior art that the quality of the extracted essential oils of spice plants is unstable, heat-sensitive and easily hydrolyzed components are seriously lost, and the flavor of natural spice plants is deteriorated, the present invention provides a set of steam distillation system and Vacuum system vacuum steam distillation equipment for extracting essential oils of spice plants. This equipment is different from traditional steam distillation in which steam enters from the bottom and passes through the extracted material layer to fully contact, disperse and gasify the spice...

Embodiment 1

[0031] After 300g of dried lavender flowers are crushed, they are evenly packed into the material distillation tank, and the height of the filling is 80% of the distillation tank, and they are evenly compressed to prevent short circuit of steam. Through the open steam coil or sieve plate, the water vapor from the steam generator is evenly heated from top to bottom gradually, and at the same time, the saturated steam is gradually condensed by the material layer and the hot water formed by the material layer continuously penetrates into the material tissue. During the process of steam diffusion and condensation, a good water dispersion effect is formed; with the continuous entry of water vapor and the action of the vacuum water pump, the oil-water mixed steam is introduced into the condenser through the steam outlet at the lower part of the material tank to fully condense, and the cooled oil-water The mixed liquid is received in the oil-water separator, and the crude product of t...

Embodiment 2

[0033] Cut 300g of lavender half into 2-3cm, crush it a little and put it evenly into the material distillation tank. Through the open steam coil or sieve plate, the water vapor from the steam generator is evenly heated from top to bottom gradually, and at the same time, the saturated steam is gradually condensed by the material layer and the hot water formed by the material layer continuously penetrates into the material tissue. During the process of steam diffusion and condensation, a good water dispersion effect is formed; with the continuous entry of water vapor and the action of the vacuum water pump, the oil-water mixed steam is introduced into the condenser through the steam outlet at the lower part of the material tank to fully condense, and the cooled oil-water The mixed liquid is received in the oil-water separator, and the crude product of the essential oil is obtained after being separated by the oil-water separator; the condensed small amount of condensed water con...

Embodiment 3

[0035] Put 5kg of half whole lavender plants evenly into the material distillation tank, the height of the filling is 80% of the distillation tank, and evenly compress to prevent the short circuit of the steam from the steam generator through the open steam coil or sieve plate The water vapor gradually heats the material layer from top to bottom evenly, and at the same time, the saturated steam is gradually condensed by the material layer, and the hot water formed by the material layer continuously penetrates into the material tissue, and the material forms a good water dispersion effect in the process of steam diffusion and condensation; With the continuous entry of water vapor and the action of the vacuum water pump, the oil-water mixed steam is introduced into the condenser through the steam outlet at the lower part of the material tank to fully condense, and the cooled oil-water mixed liquid is received in the oil-water separator and separated by the oil-water separator.

Abstract

The invention provides a piece of equipment and a method for extracting volatile essential oil from natural perfume plants by using the technology of reduced pressure steam distillation extraction. The equipment provided in the invention comprises a steam distillation system and a vacuum system, wherein the steam distillation system is composed of a steam generator, a material retort, a condenser, an oil-water separator and connecting pipelines, and the vacuum system comprises a vacuum unit or a suction pump, a pressure regulator valve, connecting pipelines and the like. The method comprises the following steps that: plant raw materials to be extracted for essential oil in the material retort is controlled to be at a certain temperature and under certain pressure so as to reduce changes of aroma components in perfume plants in the process of extraction as much as possible; extracted volatile components of essential oil is mixed with steam to form mixed steam of water and oil; the mixed steam enters into the condenser for condensation and then enters into the oil-water separator for separation; an oil phase is collected after separation and the oil phase is plant essential oil; the separated water phase is flower water. The essential oil and flower water obtained by the extraction method have pure aroma, suffer little loss for head volatile thereof, and are applicable to the industries of perfumes, essence, cosmetics, daily chemicals, etc.

Description

technical field [0001] The invention relates to a device and a method for extracting spice plant essential oil. More specifically, the present invention relates to a device and method for extracting volatile essential oils from natural spice plants by using a decompression steam extraction technique. Background technique [0002] Spice plant essential oil processing is an ancient industry. The ancient Egyptians extracted essential oils from herbs, fruits, vegetables, woody plants, flowers and other plants to treat diseases and worship gods, and also used them as preservatives for making mummies; the Greeks learned from Egypt and used essential oils in large quantities in cosmetics, Medical treatment and prevention of infectious diseases; In 100 BC, the Romans used plant essential oils in massage, and with the Crusades, knowledge of spices and essential oils also began to spread to Europe. However, due to the extremely rare and precious nature of essential oils, for a long ...
