Products Description
With the improvement of people's living standards, the demand for coffee is getting higher and higher. In addition to the need to drink coffee, coffee can also be dried to make other drinks. So what is the coffee drying process?
1: Coffee drying process principle
The coffee drying process is to grind coffee powder into coffee liquid, and then pump into the heater for evaporation and drying. The hot air evaporation process is as follows :1, introduce air from the outside 2, start the fan 3, open the heat exchanger 4, generate convection 5, push the fan 6, make the air flow through the coffee powder 7, heat exchange 8, form a whirlwind 9, through the coffee ball 10, release heat
2: Air energy machine selection precautions
In the selection of air energy, we need to pay attention to the following points: 1. The advantages and disadvantages of air source. Different types of air sources have different advantages and disadvantages, so when purchasing air sources, you should choose according to your actual situation. 2. Requirements for performance indicators. As a qualified air source equipment, it must have good operating efficiency, energy saving and reliability requirements. 3. Environmental adaptability. If the environmental conditions are not suitable for the use of the product, it will cause performance degradation or even damage. 4. Life requirements. When purchasing air energy equipment, its service life should be considered, generally 5-10 years or more.
3. Coffee drying method and process
In the coffee drying method, there are two main ways: hot air drying and steam drying. Hot air drying is a drying process that evaporates water from the material. Gas or oil is usually used as fuel to produce high temperature air flow, which is blown out by the fan to evaporate water into the atmosphere; At the same time, it is also necessary to use a fan to blow water to the surface of the material for drying. Hot water steam method Water steam method is a direct drying technology by adding water to raw materials, powdered sugar and other substances to form a liquid state, and then heating it into a gaseous state, and release heat to reduce it to distilled water. This method can effectively control the temperature, and does not waste energy.
If you want to make certain drinks by roasting, you must use the coffee drying process. There are generally three ways of roasting coffee: hot, cold brew and rinsing. All three of these methods affect the quality and taste of coffee. Therefore, when choosing coffee roasting, we must make appropriate adjustments according to our own requirements. In the specific coffee drying process, the coffee beans need to be cleaned and screened first, and then put into the roaster. The roaster roasts the beans to varying degrees of ripeness depending on the set temperature and time.
During the roasting process, coffee beans will constantly release water and carbon dioxide, forming a special smell and taste. The longer the roasting time, the darker the color of the beans, the more bitter the taste. On the contrary, the shorter the roasting time, the fresher the taste of coffee beans, and the more aromatic the taste. During the baking process, the temperature and baking time need to be constantly adjusted to achieve the best taste and aroma. At the same time, it is also necessary to pay attention to the turning of the coffee beans to ensure that the coffee beans are evenly heated. After roasting, it needs to be cooled for a period of time to slow down the oxidation of the beans and maintain their freshness. In short, the coffee drying process is a complex and delicate process that requires the support of technology and experience. Only by mastering the correct roasting methods and processes can we produce high-quality coffee beans and meet people's continuous pursuit and demand for coffee.
