Description

Tunnel coffee bean roasting device

technical field

The utility model relates to a roasting device, in particular to a tunnel-type coffee bean roasting device.

Background technique

Coffee is a drink made from natural plant seeds. It has a special aroma and a sweet taste, and the caffeine contained in it has a stimulating and refreshing effect on the human body. It is one of the widely popular drinks in human society.

The pros and cons of coffee beverages are mainly in the process of roasting coffee beans. Therefore, many manufacturers have introduced roasters from abroad (such as Germany, the United States, Italy, Spain, Turkey, Japan, South Korea, China, etc.), and there are also domestic roasters. Many manufacturers have invested in R&D and production; however, the roasting barrels used in the coffee roasters currently on the market are mainly metal barrels, and the materials used are mostly stainless steel and cast iron alloys (this material refers to internationally renowned brands). Direct fire, hot air, semi-direct fire or semi-hot air heating and roasting; however, no matter which method of heating and roasting is used, it is difficult to control the coffee beans in the optimal heating and roasting state, and therefore internal and external heat is generated. Unevenness often results in scorched outside and undercooked inside, and the coffee bean oil cannot be evenly released to show the best flavor.

On the other hand, there are many types of coffee beans and different production areas (such as Ethiopia, Honduras, Peru, Guatemala, Nicaragua, Colombia, Mandheling, Brazil, Costa Rica, etc. different types of coffee beans), and different types of coffee beans have different roasting temperatures and different flavors.

During the roasting process of coffee beans, the residual water in the coffee bean cells is converted into water vapor, but the thickness of the cell wall (not silver skin) of coffee beans is about 6 microns, which is not only thicker than ordinary plants, but also seems to be a Small pressure boiler, so the internal material of the cell undergoes a non-enzymatic browning reaction at high temperature and high pressure, that is, the Maynard reaction.

First burst: refers to the first burst of coffee beans during the roasting process. Usually, when the temperature of the coffee beans reaches 180°C to 200°C during the roasting process, the fibrous tissue of the coffee beans begins to harden, causing the pressure of the bean core to be unable to be discharged smoothly and the internal pressure to rise rapidly. . Due to the rapid changes in coffee bean temperature, coffee bean moisture content, and pressure, the chemical reaction speed at this stage is accelerated, and the coffee bean expands rapidly, resulting in the first burst.

At about 170°C, the caramelization reaction begins. This allows the sugars to be broken down further. Maynard's reaction gradually slowed. The caramelization reaction deepens the color of the coffee beans and creates aromas such as fruit, caramel, and roasted nuts. Both the caramelization reaction and the Maynard reaction reduce the sweetness in coffee and increase the bitterness of coffee.

Second burst: refers to the second burst of coffee beans during the roasting process. Usually, the temperature of the coffee beans reaches 205°C to 230°C during the roasting process. After the second explosion begins, the oil of the beans will surface, which is the stage of deep roasting. After a burst, some of the resulting components begin to decompose while heating up, and gas is produced during this process, which keeps the beans swollen. With the expansion of the coffee beans, the cells are destroyed again, followed by a sound, which is called a second explosion.

Dry distillation reaction: refers to the isolation of solid or organic matter from air, dry burning to complete carbonization, and isolation of air to prevent oxygen from supporting combustion or explosion.

Under normal roasting, coffee beans cannot be roasted until they are completely carbonized and burned. Therefore, dark roasted beans are released before burning, and roasted into medium-dark roasted to dark roasted after the second explosion. Because of their low acidity, they are the most acceptable to the general public. Among the popular specialty coffees in Europe and America, the lighter medium to medium-dark roasts are the main ones, and they are rarely roasted to the dark roast of the second burst or the heavy roast of the second burst, but the roasting degree of the second burst is very low. But it is the characteristic of specialty coffee. The beans are shiny and the roasting technique is in place. Not only is it not burnt or bitter, but it also exudes the sweet taste of alcohol and pine resin, similar to the aroma of banana oil, pine resin, fir or nutmeg.

Therefore, the dark roasted aroma can be attributed to the retort reaction. The aromas of light roasting and medium roasting belong to low and medium molecular weight, but after entering the deep roasting world after the second explosion, carbonization is intensified, caramelization reaction disappears, but the Maynard reaction continues, and the fibers of amino acids and polysaccharides are continuously Degradation and polymerization produce more high-molecular-weight binding compounds. The flavor interpretation is dominated by the transformation of caramel from the Maynard reaction and the dry distillation reaction, with caramel, stuffy and spicy.

On the other hand, the roasting degree of coffee beans is divided into light roasting, cinnamon roasting, medium roasting, high roasting, city roasting, dark city roasting, French roasting, and Italian roasting. Same. Light roast, beans are roasted to near the first burst; Cinnamon roast, beans are roasted to the middle of the first burst; Medium roast, beans are roasted to the end of the first burst; ; Urban Roast, the beans are roasted until the second burst; Deep City Roast, the beans are roasted to the end of the second burst period; French Roast, the beans are roasted to a black surface with a little tawny; Italian Roasting, the coffee beans are roasted to an all-black state.

As far as the current coffee roasting equipment is concerned, metal drums are used to directly provide heat to roast coffee beans. The dried coffee beans are easily roasted at high temperature and lose the original juice of the beans, thereby destroying their fats and oils, and then losing the best and most natural coffee beans. Due to the high temperature direct fire roasting, the beans are easily scorched, and the fat will be converted into compounds harmful to the human body when subjected to high temperature carbonization, which is also a serious shortcoming of the current roasting technology and equipment.

According to this, how to design the heating temperature in the roasting device can be accurately controlled, so that the coffee beans retain the natural aroma and original taste, and the taste is mellow without being bitter, burning, or carbonizing, and then imparting a real healthy drink, which is the best in the field. One of the topics that needs in-depth research and improvement.

Therefore, after observing the above-mentioned deficiencies, the creator of the present case believes that further improvement of the coffee bean roasting device is still necessary, and thus the present invention is produced.
