Embodiment Construction

[0013] figure 1 A schematic diagram of a coffee bean roaster 100 according to an embodiment of the present invention is shown. like figure 1 As shown, coffee roaster 100 includes vessel 110 , combustion chamber 120 , combustion chamber monitor 130 , and optional display 140 . The container 110 contains the coffee beans to be roasted therein, and roasting is performed in the container 110 . Combustion is carried out in the combustion chamber 120 to provide heat to the container 110, and firewood is generally used as fuel in the combustion chamber 120, thereby in addition to providing heat to the container 110, the pollution of coffee beans can also be reduced and the aroma of the wood can be used to increase roasting. The aroma and quality of the coffee after. The combustion chamber monitor 130 monitors both the vessel 110 and the combustion chamber 120 , obtains the current temperature of the vessel 110 , and controls the combustion intensity of the combustion chamber 120 a...

Abstract

The invention discloses a coffee bean roaster. The coffee bean roaster comprises a container, a combustion chamber and a combustion chamber monitor, wherein coffee beans to be roasted are placed in the container; combustion is performed in the combustion chamber to provide heat energy for the container; and the combustion chamber monitor obtains the temperature of the container and controls the combustion intensity of the combustion chamber according to the temperature of the container and the preset relationship between the coffee bean roasting temperature and time. The relationship between the coffee bean roasting temperature and time contains the following three stages: 1) fast cooling stage, the temperature is reduced from 210 DEG C to 140-170 DEG C in 10 minutes; 2) slow heating stage, the temperature is increased to 50-75 DEG C in 70 minutes; and 3) fast heating stage, the temperature is increased to 40-70 DEG C in 10 minutes. The invention also discloses a coffee bean roasting method which is suitably performed on the coffee bean roaster.

Description

technical field [0001] The present invention relates to a roasting method for coffee beans and a roasting furnace adopting the roasting method. Background technique [0002] Robusta coffee is mainly produced at an altitude of 300-600 meters or flat land. The flowers of this variety of coffee are pollinated by insects attracted by its own strong aroma, and the shape of its seeds is relatively round. The side with the cracks in the middle is a little swollen, and the grooves are straight; the color of the seeds is slightly grayish light green, the particles are smaller than the Arabica seeds, and the taste is inferior to the former. Currently, it is used for instant coffee and blending. The basic bean of coffee; its advantages are that it does not require too much care from people, is not afraid of rust disease, and has twice or three times the caffeine content of Arabica coffee beans. [0003] Existing roasters for roasting coffee beans generally use wood as fuel, the temper...
