ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to an apparatus for roasting raw coffee beans, which apparatus is capable of instantly roasting a small quantity of raw coffee beans according to personal taste, and provides a unique taste and fragrance of coffee, and in particular to an apparatus suitable for home use.
Coffee is a popular drink. Drinking coffee has been prepared by boiling raw beans with a percolator or by mixing coffee powders in boiling water. In the present days, however, people have a tendency to prefer raw bean coffee which is superior in taste and fragrance.
In spite of its quality, the taste and fragrance of raw bean coffee can be changed not only by the ways of processing raw beans, but also in the manner it is stored. Thus, in order to enjoy the particular taste and fragrance of raw bean coffee, after purchasing raw beans in a small quantity, people have to instantly process raw beans properly whenever required.
SUMMARY OF THE INVENTION
The present invention was made with a view to satisfying the aforementioned requirements, and its object is to provide an apparatus for roasting raw coffee beans at home according to personal taste.
To accomplish the object of the present invention there is provided an apparatus for roasting raw coffee beans comprising a main housing having an air inlet; a blower fan assembly mounted on the main housing for blowing air; a heater assembly mounted on the housing and above the blower fan assembly for generating heat, the blower fan assembly directing the heat upwardly; a roasting vessel above the heater assembly for containing raw coffee beans to be roasted; a hull-receiving vessel for receiving and storing the hulls of the raw coffee beans blown along the air stream directed thereto from the roasting vessel, the hull-receiving vessel having an air outlet; a cover for covering the roasting vessel, the cover guiding hulls from the raw coffee beans along the path of the air stream; and a power means for providing power to the blower fan assembly and the heater assembly.
The apparatus of the invention is adapted to roast raw coffee beans by means of a heated airstream for a predetermined period of time, to simultaneously remove raw-bean hulls, and then to apply a cooling airstream at the end of the roasting process.
