Embodiment Construction

[0021] It should be noted that the device of the present invention is not only suitable for the extraction of fenugreek, but also suitable for the extraction of other plants, especially plants containing volatile oil components, such as oregano, peppermint, perilla, ageratum, etc., and the following takes the extraction of fenugreek as an example. illustrate. The microwave generation and introduction device of the present invention can adopt the prior art, for example, adopt the metal tank body that is provided with microwave feeding port, microwave is fed into the tank body through the non-metallic microwave wave-transmitting guide sleeve, preferably microwave feeding port is deep in the tank body and uniform distributed in its inner circumference. A detailed description will be given below in conjunction with the accompanying drawings.

[0022] Such as figure 1 As shown, the microwave extraction device of the present invention includes a microwave generator 1, a microwave ...

Abstract

The invention relates to a microwave extracting device. The microwave extracting device comprises a microwave extracting tank (3) with a microwave feed-in hole, wherein the upper part of the microwave extracting tank (3) is connected with a condenser (6) and is provided with a material returning hole (4), the material returning hole (4) is provided with a spray header (5), the lower part of the microwave extracting tank (3) is provided with a sealing head (8) with a discharge hole (11), the discharge hole (11) is connected with the material returning hole (4) by virtue of a pipeline through a pump (12) to form a circulating bypass, the upper part of the sealing head (8) is provided with a baffle (9) with a hole, and a screen mesh (10) is arranged on the baffle (9). With the adoption of the microwave extracting device, volatile components such as thymol and the like and water soluble extractum are synchronously extracted, herba elsholtziae resources are comprehensively utilized, the processing cost is low, and a foundation of application of herba elsholtziae to the field of food additives is laid.

Description

technical field [0001] The invention belongs to the field of plant extraction equipment, and in particular relates to a microwave extraction device and a method for extracting fenugreek. Background technique [0002] Lemongrass, a perennial herb belonging to the family Lamiaceae, is used for both medicine and food. Contain 1-2% volatile oil in the whole herb of fenugreek, and the main components of volatile oil are thymol and carvacrol. Thymol, also known as thymol, has a molecular weight of 150, is a colorless transparent crystal, has a special odor, is volatile at 100°C, and can be distilled together with water vapor; melting point is 51.5°C, boiling point is about 233°C; solubility is 1g in about 1000ml Water, 1ml ethanol, the bactericidal effect is stronger than phenol, and the toxicity is low. Flavonoids are also contained in the whole herb of Lemongrass, which has functions such as anti-oxidation, anti-aging, antibacterial, and anti-cancer. Generally, the volatile o...
