Coffee is a kind of plant fruit-> peeling-> drying-> shelling-> baking-> blending-> grinding-> conditioning and drinking beverage.

Second, the common coffee in the market can be divided into two categories:

a. Coffee essence (Instant Coffee): because it dissolves when it comes into contact with water, it is also called instant coffee (Soluble Coffee). It is made by grinding coffee beans into liquid and then into seasoning, and then crystallized by spray.

The way of crystallization is divided into: (1) High temperature dehydration crystallization, known as the first generation of caffeine, in the form of powder, with a bitter taste. (2) low temperature dehydration and crystallization, known as the second and third generation coffee essence, is granular and can retain the original taste of coffee. Caffeine dissolves when exposed to water and is the main raw material for making three-in-one coffee. it is also widely used in candy and biscuits and rarely in the catering market.
