Because of the large investment in production equipment, the production of instant coffee can not be produced in small and medium-sized towns, so they can only sell raw materials. Pure coffee tastes too bitter, and the eating habits of our country make most people unaccustomed to the bitter taste.
The production equipment of flavored coffee has the advantages of low investment, simple operation and low bitterness. it is only necessary to mix a single variety with other ingredients (the ingredients of different varieties of coffee can be properly adjusted during roasting) to get brown coffee powder based on the color and flavor of coffee. and then mix to get a good flavor, convenient to drink flavor coffee.
