Summary: Roast coffee beans.                                                                             

Coffee roasters in food processing machinery are specialized machines designed to transform green coffee beans into the aromatic, flavorful roasted coffee beans we consume. This process is crucial because raw green coffee beans are not palatable and lack the characteristic coffee flavor and aroma.

Function: Coffee roasters apply heat to the green coffee beans, causing a series of physical and chemical changes. These changes develop the coffee's flavor, aroma, acidity, and body. The roasting process:

    * Dries the beans.

    * Causes them to turn brown.

    * Releases volatile compounds that create the coffee's distinctive smell and taste.

Mechanism: Roasters employ various heating methods, including:

    * Drum roasters: Beans are tumbled in a rotating drum heated by gas or electricity.

    * Air roasters:  Hot air is used to fluidize and roast the beans.

Importance: Coffee roasters are essential for:

    * Developing the desired flavor profile of coffee.

    * Ensuring consistency in coffee quality.

    * Preparing coffee beans for grinding and brewing.
