Description

Coffee bean breaking device

This creation is about a coffee bean processing device, especially a coffee bean wall breaking device.

Generally speaking, after the coffee beans (green coffee beans) are washed or dried in the sun, a roasting process is performed, that is, the green beans are heated, and a series of physical and chemical reactions occur to make the coffee beans Gradually appear brown, after the roasted coffee beans are ground and brewed, they can form coffee drinks with special aroma.

Coffee green beans contain a large amount of chlorogenic acid. Chlorogenic acid has good antioxidant capacity, which can remove free radicals, lower blood pressure, lower blood sugar, burn fat and lose weight, and even have anti-tumor effects. After this roasting process, the chlorogenic acid in the coffee beans will be destroyed by high temperature, so that the content of chlorogenic acid will be greatly reduced. Therefore, the coffee beverage brewed by the roasted coffee beans cannot be taken from it. Ortho.

Therefore, in the coffee bean wall breaking device of the third embodiment of the present invention, after the supercritical carbon dioxide fluid (and / or the subcritical carbon dioxide fluid) is brought into contact with the coffee green beans in the green bean processing space 11 for the predetermined time, A worker can open the second check valve V2, so that the supercritical carbon dioxide fluid in the raw bean processing space 11 can be restored to the carbon dioxide gas (and / or the carbon dioxide liquid), and transported to the pipeline along the pipeline group T2. CO2 recovery module 3. At this time, because the pressure of the carbon dioxide gas (and / or the carbon dioxide liquid) is higher than the predetermined value, part of the carbon dioxide gas (and / or the carbon dioxide liquid) can flow from the exhaust port H2 of the pressure valve V7 to the external environment. The remaining carbon dioxide gas (and / or carbon dioxide liquid) can be transported to the carbon dioxide recovery module 3 and finally stored in the storage space 311.

To sum up, the coffee bean wall breaking device of the present invention, with the setting of the carbon dioxide recovery component, when the supercritical carbon dioxide fluid in the raw bean processing space returns to the carbon dioxide gas (and / or the carbon dioxide liquid), It can be transported to the carbon dioxide recovery module along the conveying pipe group and stored in the storage space. When the worker wants to perform the next batch of wall breaking treatment, the carbon dioxide gas stored in the storage space (and / Or carbon dioxide liquid) to replace (or partially replace) the carbon dioxide gas (and / or carbon dioxide liquid) from the carbon dioxide source, so the amount of new carbon dioxide gas (and / or carbon dioxide liquid) used in the wall breaking treatment can be reduced, and further To achieve the effect of reducing the cost of wall treatment.

Although this creation has been disclosed using the above-mentioned preferred embodiments, it is not intended to limit this creation. Anyone skilled in this art can make various changes and modifications to the above-mentioned embodiments without departing from the spirit and scope of this creation. The technical scope protected by the creation, so the scope of protection of this creation shall be determined by the scope of the attached patent application.
