What is the fastest way to pick coffee beans-an introduction to the process of preservation and treatment

Coffee bean roasting is a process in which raw beans are converted into sugars and acids by means of specific equipment at high temperature. in this process, substances such as cellulose will be carbonized to varying degrees, water and carbon dioxide will be volatilized, and the protein will be converted into enzymes, which combine with the rest of the fat to form an oil film on the surface of the coffee, and the coffee bean itself will expand by baking. Pores are created inside. Roasted coffee beans can produce special aromas and different flavors before they can be used to brew coffee.

Coffee bean roasting is a complicated processing technology, which is quite professional. If you want to make delicious coffee beans, you need perfect equipment and high coffee roasting technology, so unless it is for personal pleasure, it is generally not suitable for family.

With the size of the baking firepower, the length of time, coffee beans will show different depth and taste changes. Different characteristics of coffee beans, different drinking methods determine the depth of roasting of coffee beans. Generally speaking, the roasting degree is light, the coffee bean color will be light brown, the sour taste is strong, and the baking degree is deep, the hue is dark, and the bitterness is enhanced. Traditionally, the roasting of coffee beans is divided into eight different degrees:

Advantages: the fruity aroma of coffee beans can be well preserved and the price is low.

Disadvantages: coffee beans may be contaminated with the fishy smell of the ground, and the quality of coffee beans is uneven.

Fresh fruit-sun-dried-remove all pericarp, seed coat-coffee raw beans

Note: this method is mostly used for lower-grade coffee beans and is still widely used in Brazil, Ethiopia, Congo, Indonesia, Yemen and other places.

The washing method is also called wet treatment: after the outer pulp of the coffee fruit is removed by the pulp separator within 12 hours after the coffee is picked, the coffee beans are soaked in a large cement tank filled with water to separate the fruit. The coffee beans are then pasted in the fermentation box for about 12-36 hours, containing 15% water after fermentation, and the fermented coffee beans are washed clean with clean water. The coffee beans are dried in a dryer or dried in the sun, and the coffee beans are called "parchment coffee beans", waiting for export.

Fresh fruit-soak soft-remove exocarp-ferment the coffee fruit with pulp in the fermentation tank-rinse the pulp gum with water-dry the coffee fruit with endocarp-remove the endocarp with a peeling machine-polish the seed coat-coffee raw beans

Advantages: coffee beans have stable quality, beautiful color and less impurities

Disadvantages: the processing cost is too high and requires a lot of water.

Note: generally used for higher quality Arabica coffee beans, such as Blue Mountains, Colombia, Mexico, Guatemala, etc.
