Problems solved by technology

The extraction device disclosed in this patent adopts the water distillation method, and a return line is designed to return the condensed water in the collection pipe to the heater, which can extract multi-layer materials at the same time, but the condensed water flows back into the heater through the steam outlet. The steam outlet is just above the multi-layer shelf. When the condensed water flows back through the multi-layer shelf, it will take away some less volatile substances in the material to be extracted, such as sugar, amino acid, etc., and flow into the solvent. Long-term Heating, oxidation of unsaturated fatty acids, terpenoids and other substances, hydrolysis of esters, Maillard reaction, etc., are prone to occur, resulting in the formation of new substances, resulting in changes in the flavor and quality of essential oils

Embodiment 1

[0028] The plant essential oil distillation extraction device of this embodiment includes a distillation pot body 1, a condensation pipe 2, an oil-water separator 3, and a heating mechanism 4 for heating the distillation pot body 1. The heating mechanism 4 can be an induction cooker, an electric ceramic stove or an oil heater. Commonly used heating devices such as bathing pots are used to heat the water inside the still body 1 to evaporate to form water vapor. An installation ring 7 is integrally formed on the inner wall of the still body 1, and a sample tray support 5 is installed on the installation ring 7. The sample tray support 5 divides the interior of the still body 1 into two layers: a steam layer and a solvent layer. A sample tray 8 for containing distillation raw materials is installed on the support 5. The sample tray 8 is a cylinder with an open top and a screen installed at the bottom. The screen can prevent the leakage of the distillation material, and the mesh nu...

Embodiment 2

[0035] like figure 2 As shown, the plant essential oil distillation extraction device of this embodiment includes all the structures of Embodiment 1, and on the basis of the structure of Embodiment 1, a flow guide mechanism is added, and the flow guide mechanism includes a liquid receiver 171 and a drainage device connected to each other. The tube 172 and the liquid receiver 171 are located directly below the sample tray 8 and fully cover the bottom of the sample tray 8, and are used to receive the drops from the sample tray 8. The outlet end of the drainage tube 172 is connected with a liquid collection tube 18 for Collect the droplet that drops from the sample tray 8, the solution is housed in the liquid collection pipe 18, and the outlet end of the drainage pipe 172 is located below the liquid surface, for stabilizing the internal pressure of the distillation pot body 1, and the liquid collection pipe 18 can also be designed as a sealed The pipe body is equipped with a press...

Embodiment 3

[0039] like Figure 4 As shown, the plant essential oil distillation extraction device of this embodiment differs from Embodiment 2 in that the liquid receiver 171 is a cylinder with an open top and a conical bottom, and the drainage tube 172 is connected to the lowest point of the cylinder to collect The liquid all flows to the lowest part of cylinder body, and is exported through drainage tube 172. The stainless steel bracket used to support and fix the deflector mechanism in this embodiment also includes a support rod 191 and a mounting frame 192. The cylinder is installed on the mounting frame 192. The structure of the mounting frame 192 can be provided with the structure described in Embodiment 2, or it can be The truncated cone structure matched with the bottom of the cylinder can better support and install the cylinder. Similarly, one end of the support rod 191 is welded to the mounting frame 192 , and the other end can be welded to the sample tray support 5 , or can b...

Abstract

The invention relates to the technical field of essential oil extracting devices, in particular to a plant essential oil distilling extracting device. The device comprises a heating mechanism, a distilling pot body, a condensing pipe and an oil and water separator. The distilling pot body is arranged on the heating mechanism, and a sample disc support is installed inside the distilling pot body. The interior of the distilling pot body is divided into an upper layer and a lower layer through the sample disc support, a sample disc for containing distilling raw materials is installed on the sample disc support, a steam outlet is formed in a pot lid of the distilling pot body, the distilling pot body is communicated with the upper portion of the oil and water separator through a flow guiding pipe, the upper port of the oil and water separator is communicated with the lower port of the condensing pipe, a valve is arranged at the lower end of the oil and water separator, the portion, above the valve, of the oil and water separator is connected with a backflow pipe communicated with the lower layer of the distilling pot body. By adopting the overwater distilling and backflow combined mode, the essential oil yield is increased, liquid drops dripping from the sample disc are guided out of the distilling pot body through the flow guiding mechanism, reactions in the distilling process arereduced, and the essential oil flavor and quality are effectively improved.

Description

technical field [0001] The invention relates to the technical field of essential oil extraction devices, in particular to a plant essential oil distillation extraction device. Background technique [0002] Some plant essential oil flavors are usually added to existing cigarettes to improve the taste of cigarettes and increase the richness of the smoke. Plant essential oil is a secondary metabolite with volatile aromatic odor produced in plants. It is composed of simple organic compounds with small molecular weight. It is a kind of volatile oily liquid substance with special odor. Due to its various biological activities , It is often made into various essences and spices for use in food, daily chemicals, tobacco and other products. [0003] There are many methods for extracting essential oils of volatile components in plants, such as solvent extraction, supercritical fluid extraction, subcritical extraction, steam distillation, etc. Among these methods, supercritical and s...
