[0001] ROASTING MACHINE FOR COFFEE BEAN [

More particularly, the present invention relates to a coffee roasting apparatus, and more particularly, it is portable and easy to carry, and roasted green beans by using charcoal to improve the aroma and taste of roasted beans, and at the same time, The present invention relates to a coffee roasting apparatus capable of improving the quality of beans.

Coffee is a green bean that is harvested from a coffee tree and is drunk through several processes. It is an important process during the process of processing coffee beans. It is a roasting process in which green beans are heated and converted into coffee beans .

The roasting process is a process in which green beans are placed in a heated drum and roasted for a predetermined period of time. The temperature and time of heating are changed according to the type of green beans, thereby converting the flavor and taste of green beans into beans .

Traditionally, large coffee shops have roasted a large amount of green beans through a large roasting machine and sold them to users. However, since the quality is not constant and the heating temperature and time which are required to be changed according to the kind of green beans can not be adjusted delicately, There is a problem that it is difficult to preserve the fragrance and taste.

In addition, small roasting apparatuses have been popularized according to the demands of consumers who want to drink coffee after roasting them directly at home. As a conventional technology proposed as such a small household roasting apparatus, there is disclosed in Korean Patent Application No. 10-2011-129553 (Published Dec. 2, 2011). The above-mentioned conventional technology provides a portable coffee roaster which can roast a small amount of coffee using a gas burner at home or outdoors.

However, as shown in FIG. 1, the conventional technique is to prevent the roasted coffee beans from escaping to the outside by simply making the drum of the coffee roaster form a predetermined slope with respect to the ground, It takes a long time to be heated to a temperature necessary for roasting (at least 160 ~ 230 ° C), and further, there is a problem that the aroma and flavor of the roasted beans deteriorates.

The reference numerals and symbols in the drawings of FIG. 1 are independent of the detailed description of the present invention and the numbers described in the drawings.

In order to solve the above problems, the present invention has been made to solve the above problems, and it can be easily used at home or outdoor by reducing the size and volume, and the charcoal box in which the charcoal is stored is disposed, and the bean is roasted by charcoal to improve the taste and aroma And at the same time, it is provided with a quartz stone which emits far infrared rays to expose the beans to far-infrared rays, thereby obtaining a roasted coffee bean of higher quality.
