The present invention relates to a coffee roaster, and more particularly, to a roasting process in which coffee beans are roasted to roast coffee beans, and a process of separating the roasted coffee beans while cooling the roasted beans, The present invention relates to an improved coffee roaster which is easy to use and which can be easily separated and discharged while cooling the bean flour.

Generally, a coffee roaster refers to a roasting apparatus that roasts a coffee bean (green bean). In the past, a coffee roaster capable of performing a roasting and a cooling process consecutively has a function of facilitating roasting and a function of cooling, .

In the conventional coffee roaster, a heating chamber is provided in a conventional box-type machine, and a stirring blade connected to a rotary driving shaft is provided in the heating chamber, so that the stirring wing rotates while being heated, When the roasting process is completed, the roasted coffee beans are cooled inside the heating chamber and then discharged to the outside.

The conventional coffee roaster described above has a problem in that the reliability of the temperature control for heating the coffee beans is not good because the upper portion of the chamber, that is, the lid of the chamber is exposed to the outside at the time of roasting, There is a concern that the user may be burned when the user's body approaches the chamber lid at a temperature.

In addition, in the conventional coffee roaster, the inside of the heating chamber made of the heat resistant material (metal) does not easily cool even when the roasted coffee beans are cooled, and the coffee beans are more ripe than desired. There is a problem that can not be met. That is, in the case of coffee beans, not only the temperature and time of roasting but also the cooling process can be a factor that influences the flavor and taste of the coffee beans. The beans may be undesirably overcharged, or the beans may be roasted if they are corrected by heating time control to reflect such problems.

In addition, the conventional coffee roaster has a long time in the heating chamber, not only the roasting time but also the roasting time, so that the coffee bean husk is attached to the heater or sticks to the inside of the chamber, So that there is a problem that frequent maintenance is required to remove the contamination. Particularly, in the process of cooling inside the heating chamber, since the air is blown by the blowing air, peeling of the peeled coffee bean is blown away, and there is a concern that the contamination is accelerated by contact with the heater. It is impossible to provide a coffee bean of the highest quality because there is a fear of pollution which can not be avoided.

In addition, since the roasting and cooling (including peeling and separation) processes of coffee beans are successively performed in the heating chamber, it is impossible to roast a large amount of beans because the roasting can not be performed for the cooling time of the beans.

The present invention has been made in order to solve the above-mentioned problems of the prior art, and it is an object of the present invention to provide a roasting method for roasting a coffee bean by roasting a coffee bean, a process for separating the roasted beans while cooling the roasted beans, And to provide a coffee roaster which can be easily separated and discharged.
