Description

Technical Field

[0001] The utility model relates to the technical field of food detection, in particular to a shaking extraction device. Background Art

[0002] Extraction refers to the transfer of compounds from one solvent to another by utilizing the difference in solubility or partition coefficient of a compound in two immiscible (or slightly soluble) solvents. Thiourea dioxide, also known as thiourea peroxide, is an excellent reducing agent and is commonly used for bleaching fibers such as paper, silk, and wool. Eating or inhaling thiourea dioxide can cause headaches, nausea, and oral and stomach irritation, while long-term exposure can cause edema, suffocation, coma, and even death.

[0003] Among them, rice is one of the main staple foods of human beings, and its products are a kind of food processed with rice as the main raw material. In the market, common ones are rice flour, rice extruded food (rice flour, rice noodles, etc.), rice steamed food (instant rice flour, rice cake, rice cake, glutinous rice balls, glutinous rice cakes, etc.). In recent years, the abuse of bleaching agents in rice and its products has occurred from time to time, causing serious harm to people's health and life safety. In the context of the whole people's concern and attention to food safety, from the perspective of ensuring food safety and people's health, it is very necessary to investigate and analyze the addition of thiourea dioxide in rice and its products circulating on the market.

[0004] At present, for the extraction device of thiourea dioxide in a type of food, usually a single extraction operation is completed by auxiliary equipment, such as vibration extraction, ultrasonic extraction, shaking centrifugal extraction, etc., but each device is only suitable for a single extraction operation and cannot have two or more extraction operation methods at the same time. The applicability is poor, and the extraction quality of thiourea dioxide obtained by different extraction operations is also different. Therefore, the operator usually needs to be equipped with two or more auxiliary equipment to implement the extraction operation, which greatly increases the cost of use. Utility Model Content

[0035] In summary, the present application can clamp the reagent container carrying the extraction reagent through the reagent clamping component, and then the first motor 14 can drive the shaft group in turn and drive the shaking assembly 2 to rotate along the trajectory of the accommodating groove group as a whole to realize the shaking extraction operation. The second motor 212 is connected to the stage 24 through the second motor 212, so that the vibration generated by the second motor 212 can be effectively transmitted to the reagent container accommodated on the stage 24 to drive the reagent to perform vibration extraction. The operator can choose to use the above two extraction operations according to the extraction needs, which greatly improves the applicability of the present invention and solves the problem that the existing extraction device has a single operation and poor applicability.
