Technical Field

[0001] The present application relates to the technical field of coffee processing, and in particular to a multi-stage extraction device for coffee components. Background Art

[0002] Coffee is a beverage made from roasted and ground coffee beans. Coffee contains a variety of bioactive ingredients, such as trigonelline, chlorogenic acid, caffeine, phenolic compounds, etc. Phenolic compounds have antioxidant, anti-inflammatory, and anti-cancer effects, and have been widely used in food fortification; caffeine can also reduce muscle fatigue and promote the secretion of digestive juices. Drinking coffee in moderation is good for the body.

[0003] At present, a Chinese patent with publication number CN112574204A discloses a method for extracting caffeine in multiple stages, comprising the following steps: S1: putting coffee beans into the mesh cylinder through the feed port; S2: starting the cylinder, the output shaft of the cylinder drives the arc mirror reflection cover to move, the arc mirror reflection cover drives the far-infrared electric heating tube to move, and the distance between the far-infrared electric heating tube and the mesh cylinder is adjusted; S3: starting the far-infrared electric heating tube to dry the coffee beans in the mesh cylinder; S4: starting the first motor, the output shaft of the first motor drives the rotating shaft to rotate, the rotating shaft drives the mesh cylinder to rotate, so that the coffee beans in the mesh cylinder are dried evenly; S5: after the drying is completed, starting the second motor, the output shaft of the second motor drives the rotating rod to rotate, the rotating rod drives the first bevel gear to rotate, the first bevel gear drives the second bevel gear to rotate, the second bevel gear drives the screw to rotate, the screw drives the slide rod to slide downward, the slide rod drives the through slot to move downward to lower one end of the mesh cylinder, and then the discharge port is opened to discharge the material; S6: crushing the dried coffee beans and grinding them into fine powder; S7: mixing the coffee fine powder and alcohol in proportion and putting them into a Soxhlet extractor; S8: passing distilled water into the Soxhlet extractor and heating it to boil; S9: repeatedly extracting the boiled solution; S10: performing multi-stage distillation on the solution to recover the ethanol in the solution; S11: placing the distilled product on an evaporating dish and then heating it for sublimation to increase the purity of caffeine.

[0004] When using a Soxhlet extractor for extraction, the extraction bottle of the Soxhlet extractor is placed directly on the workbench; when the workbench shakes violently, the extraction bottle will shake, and the extraction tube and condenser on the extraction bottle will also shake, resulting in a worse connection between the extraction tube and the condenser, and even the extraction tube and the condenser may separate; when the extraction tube and the condenser are separated, it will affect the extraction of effective ingredients, resulting in poor extraction of effective ingredients in coffee.
