Problems solved by technology

Such a structure can realize water-isolated distillation. The material is distilled on the grate, and the water is heated under the grate to generate steam to distill the material, so that the water-soluble volatile oil will not be lost in the water of the distillation container, which overcomes the traditional volatile oil determination. The instrument can only be distilled in water, and some plant essential oil components are too much dissolved in water, which reduces the oil yield of the tested plant essential oil, and the defect of incomplete essential oil components

Embodiment 1

[0031] Embodiment 1, the structural design of volatile oil extraction and separation device

[0032] like Figure 1-4 Shown is the plant volatile oil extraction device provided by the present invention, including distillation device, condensation device and collection device;

[0033]Wherein, the distillation device includes a barrel-shaped distillation vessel 1 with an open upper part, a sealing cover 2 matching the distillation vessel 1 and a water-proof grate 15 matching the distillation vessel 1, and a through hole 16 is arranged on the top of the sealing cover 2; the distillation vessel 1 is Made of white iron or stainless steel, chemically stable, heat-resistant; diameter 16cm, height 24cm. The built-in water-retaining grate 15 is two semicircles, perforated on the top, supported by legs below, can be freely taken out from the distillation pot, and the grate is 10cm apart from the height of the bottom of the pot. The water-repelling grate 15 is made up of two semicircu...

Embodiment 2

[0051] Embodiment 2, prepare plant essential oil with the plant volatile oil extraction separation device of embodiment 1

[0052] One, the using method of plant volatile oil extraction separation device of the present invention is as follows:

[0053] 1. Put the water-separating grate 15 into the body 1 of the distillation pot, put the raw materials on the grate (water distillation), but the water surface should not be higher than the grate, and ensure that the raw material layer will not be splashed when the water boils until it evaporates; it can also be taken out Water-proof grate (distilled in water), add appropriate amount of water to the bucket, and put the raw materials into the water.

[0054] 2. Put the bell-shaped cover 2 on the water seal tank, and pour a certain amount of water into the water seal tank.

[0055] 3. Connect the distillation device, condensation device, collection device and liquid return device according to the above connection method.

[0056] 4...

Abstract

The invention discloses a plant volatile oil extractor and application thereof. The device comprises a distiller, a condenser and a collector. The distiller comprises a distilling container, a sealing cover matched with the distilling container and a water-resisting grate matched with the distilling container. The top of the sealing cover is provided with through holes. The condenser comprises a condenser pipe. The through holes at the top of the sealing cover are connected with the lower end of a vertical gas tube. The gas tube is connected with the inlet of the condenser pipe by a connecting bend. The outlet of the condenser pipe is connected with the inlet of the collector by the connecting bend. The plant volatile oil extractor in the invention can be used for fast extracting volatile oil with different specific weights in plants. The extractor has the characteristics that the extractor is convenient, easily disassembled and carried, simple to load and unload materials, and suitable for distillation requirements of water-resisting distillation, water distillation, backwater distillation and non-backwater distillation, and has high extraction rate. The extractor can be used for laboratory, in particular for field.

Description

technical field [0001] The invention relates to a plant volatile oil extraction device and its application. Background technique [0002] Plant volatile oil, also known as essential oil, is a general term for a type of volatile oily liquid that exists in plants and can be distilled with water vapor, and most of them have aroma. For volatile oils, especially in the production of high-end spices, different extraction methods have a great impact on the aroma substances, so it is very important to choose an efficient and feasible extraction method. [0003] Currently used extraction methods include steam distillation, solvent extraction, pressing, supercritical fluid extraction (SFE), microcapsule-two-phase extraction, etc. In actual production, steam distillation is the most widely used. However, there are still many deficiencies in the traditional steam distillation measurement device, which can only be distilled in water, resulting in too much loss of water-soluble componen...
