The importance of cultivating beans after roasting Coffee Powder Fine Coffee beans
Each coffee bean contains about 200000 individual cells, each of which operates like a tiny pressure vessel, like a small reaction device. In the early stage of roasting, the moisture in the raw beans dissipates quickly, and the living water in the coffee begins to evaporate. With the increase of the temperature of coffee beans, the evaporation of water will put pressure on the cell wall. in this process, the element of water plays a leading role, and there is a series of very interesting reactions with the oil in the coffee. As the pressure increases, the cell wall begins to expand. The evaporation of water causes the cell wall to slowly harden. As the roasting process continues down, the pressure inside the beans increases, and the coffee oil is brought into the tiny pores in the cell wall, creating a sealing effect that retains carbon dioxide, other aromas and coffee aromas.
What does this have to do with packing? This important question requires a glimpse into the mysteries of the cell wall structure in coffee beans. The cell walls in coffee beans are only about 5 microns thick, and they can withstand the pressure of 140psi (pounds per square inch), which mainly comes from carbon dioxide produced during the second half of the baking process. Finally, a few days after the baking cycle, the so-called gas release process begins, and carbon dioxide begins to dissipate from the coffee beans.
The exhaust process of coffee beans is much longer than that of coffee powder after grinding, and the exhaust phenomenon of coffee beans will also shorten the life of coffee beans. In the early exhaust process, the air will replace the escaped carbon dioxide at about 1:1, and the air contains about 21% oxygen, so the air absorption will quickly oxidize the coffee, the coffee will continue to exhaust, the internal pressure of the coffee beans will decrease, and the exhaust speed will begin to slow down. Over time, 12-ounce bags of baked beans release more than half a cubic foot of carbon dioxide.
What about the impact on the development of taste? Experiments have shown that the taste of coffee beans changes more in the first five days than in the next five days, mainly because exhaust is the most active during the first five days of baking.

1. The air inside this crack has a different thermal conductivity than the beans outside. If it causes the two temperatures to be different. Most likely the problem lies in the fact that the air is much warmer than the beans. For example, it's too hot to get out of the oven, or the beans aren't dry enough. You'll see that the middle is more burnt than the sides. Generally, after burning, the explosion will be a little faster, perhaps not dense. At this point, it's possible that some of the beans

The steps of making coffee in smart cup are shown in the list. Here, we should explain to the students what we should pay attention to when using smart cup to make coffee: 1. Be sure to grind and drink now. Try not to buy coffee powder directly, but to buy freshly roasted coffee beans. Because the flavor and charming taste of the coffee will soon change or even disappear after it is ground. 2. Make your own coffee. Coffee
