Embodiment 1

[0031] see figure 1 , the natural aromatic plant multi-solvent extraction tank of the present embodiment, the extraction tank 2 is a sealed tank body provided with an insulating layer, the extraction tank 2 is connected to the storage tank 1, and one end of the extraction tank 2 is provided with an air inlet 4 for the multi-component solvent vapor, The other end is provided with an air outlet 17, and the extraction tank 2 is provided with a screw conveyor 3 fixed on the central axis, and the central axis is connected to the motor (not shown in the figure), so as to drive the screw conveyor 3 fixed on the central axis to surround The center rotates to transport the natural aromatic plants, and the two opposite ends of the extraction tank 2 are provided with a feed inlet 18 and a waste outlet 19 . One end of the extraction tank 2 is provided with an air inlet 4 for multi-component solvent vapor on the upper part of the waste outlet 19, and several gas evaporators connected to th...

Embodiment 2

[0039] It is the same as the first example, except that the tea extract is extracted using a multi-component extraction tank. 20kg of pulverized tea leaves are stored in storage tank 1 . Similar to Example 1, water, ethanol and carbon dioxide were used as extraction solvents. First control the temperature of the extraction tank 2 to a set temperature of 110°C, open the gas inlet valve 12, and close the gas outlet valve 13. Water, ethanol and carbon dioxide are heated and vaporized in steam generator A 5, steam generator B 6, and steam generator C 7 before entering the extraction tank 2, controlled by flow valve A 8, flow valve B 9, and flow valve C10, The flow of water is 20L / min, the flow of ethanol vapor is 20L / min, and the flow of carbon dioxide is 60L / min, continuously feed until the pressure in the tank reaches 200kPa, close the gas inlet valve 12. At this moment, the feed rate of the control feed port 18 is 1kg / min. The tea powder is pushed by the blades of the screw ...

Abstract

The invention discloses a multi-solvent extraction tank for a natural aromatic plant and a use method of the multi-element extraction tank. A spiral conveyor is arranged in the extraction tank, the extraction tank is provided with a feed port, a discharge port and a multi-solvent steam inlet, and a plurality of gas evaporators connected with the solvent tank are respectively connected with a steam inlet pipe and a multi-solvent steam inlet through gas flow valves; the other end of the extraction tank is provided with a gas outlet which is connected with a perfume storage tank through a gas outlet valve and a condenser. The method comprises the following steps: putting natural aromatic plants into the extraction tank, and enabling multiple extraction solvent steam with different polarities to enter the extraction tank to be in full contact with the natural aromatic plants until extraction steam carrying aromatic components of the extracted natural aromatic plants enters the condenser and a perfume collecting tank after extraction is completed. The method can improve output of the natural perfume extract, and is suitable for large-scale extraction of natural perfume plants. Meanwhile, multiple extraction solvents with different polarities are introduced into the extraction tank, so that the extraction efficiency is improved, and thermal decomposition and loss of different types of aroma substances are avoided.

Description

technical field [0001] The invention relates to natural fragrance extraction equipment, in particular to a multi-component extraction tank for natural aromatic plants and its use method. Background technique [0002] The chemical components of the constituent substances in plants can be divided into three categories. The first category is highly volatile substances with a molecular weight below 200, such as: alcohols, ketones, aldehydes, esters, and sulfur-containing compounds; the second category is those with a molecular weight of 200-400. Components, such as: sesquiterpenes, diterpenes, triterpenes and their various oxygen-containing derivatives, amino acids, etc.; the third category is macromolecular compounds with a molecular weight above 400, such as: tannins, peptides, polysaccharides and starches Wait. Extracting aroma components from natural aromatic plants to prepare natural spices is a long-standing, ancient and effective method that has been passed down for thou...
