Coffee beans become instant coffee, enjoy the aroma instantly

The transformation of coffee beans

Coffee is a must-have drink for many people in the morning. Its rich aroma and unique taste can awaken the sleeping soul and make people refreshed. In the fast-paced modern life, instant coffee has become a convenient choice for more and more people. So, how do you turn coffee beans into instant coffee? Let's follow me to explore this magical process.

Step 1: Baking

To make delicious and fragrant instant coffee, you need to roast it first. Freshly picked coffee berries are peeled and pulped to get unprocessed coffee beans. These unprocessed beans contain a lot of water and other impurities, and have not yet released the complex flavors that they have when fully mature.

Therefore, before making instant coffee, these green beans need to be roasted. Through high temperature heating, the moisture inside the coffee beans gradually evaporates, making the beans dry. At the same time, roasting can also stimulate the aroma and flavor substances in the coffee beans, making them more intense.

Step 2: Crushing

After roasting, the coffee beans have acquired a certain aroma and flavor, but they are still whole beans. In order to make instant coffee, these coffee beans need to be crushed into fine particles.

Usually, mechanical equipment is used to crush coffee beans. These devices will break the hard coffee beans into particles of different sizes, and the particle size can be adjusted as needed. The final result is a uniform and fine coffee powder.

Step 3: Dissolve

The most critical and complex part in making instant coffee is how to quickly transform tiny vertical smooth crystals in a solid state into a uniform solution in a liquid state.

To achieve this goal, two methods are usually used in the process of making instant coffee: spray drying and freeze drying. Spray drying is to atomize the coffee concentrate through a high-pressure nozzle, so that it quickly contacts with hot air and evaporates to form fine particles. Freeze drying is to quickly freeze the coffee concentrate under low temperature conditions and use the sublimation effect in a vacuum environment to directly convert the water from solid to gas.

Step 4: Packaging

After the dissolution process, instant coffee has the characteristic of being drinkable immediately, but it is also more susceptible to external environmental factors (such as humidity, oxygen, etc.) and loses flavor and quality.

Therefore, in the last step, the instant coffee needs to be packaged. Common packaging methods include aluminum foil bags, glass jars, etc. These packaging materials can effectively isolate the impact of external humidity and oxygen on product quality and maintain the freshness and taste of the coffee.

Conclusion

Through the above steps, coffee beans successfully complete the transformation process from solid to liquid and then back to solid, and finally become the instant coffee in our hands. This process requires not only the support of science and technology, but also a deep understanding of the characteristics and flavor of coffee beans themselves.

Whether it is traditional grinding and brewing or modern instant coffee production, it is inseparable from the careful control of coffee raw materials and process flow. Only instant coffee produced in such a rigorous and professional environment can truly bring people a rich, delicious, convenient and fast enjoyment.
