Description

Coffee roaster {COFFEE ROASTER}

The present invention relates to a coffee roaster, and more particularly, to a coffee roaster that optimizes heat efficiency while maintaining a constant internal temperature of a housing, hot air processing the inside of the housing to roast the coffee beans, The present invention relates to a coffee roaster capable of roasting a coffee bean stably even by an unskilled person.

Generally, to make delicious coffee, various conditions are necessary, but the most important thing is roasting coffee beans.

Coffee beans must be roasted at the appropriate temperature and heat to obtain flavorful coffee. Coffee beans imported from origin are roasted in large quantities in large-scale processing enterprises and then put into sealed containers for a long period of time. There are disadvantages.

In recent years, consumers' needs and consumption culture have changed and they want to drink coffee that is fresh and suitable for their personal taste. Therefore, "coffee roaster" has been developed in each home or small coffee shop to make coffee by instant roasting have.

In a typical coffee roaster, a cylindrical drum is rotatably coupled to the inside of the housing, and the coffee roaster accommodated in the cylindrical drum is roasted by the heat source provided at the bottom of the housing and the cylindrical drum.

However, in such a coffee roaster, if the size of the flame provided in the heat source feeder, for example, the combustion burner is very large, the temperature of the cylindrical drum is rapidly raised to damage the coffee beans, while if too small, the temperature of the inside of the cylindrical drum is low, It takes a lot of time to rise to a proper temperature of the flask and there is a problem that flavor and fragrance are deteriorated.

In addition, since the amount of heat transferred to the surface of the drum containing the coffee beans through the flame is large, the temperature of the roasting temperature of the coffee roaster is easily raised or lowered even when the flame of the flame supply device is slightly increased or decreased. There was a problem that the incense could not be kept constant.

Therefore, unless you are a very skilled technician, you can not maintain a consistent taste and flavor when you roast the same coffee beans.

The roasting rate of a large amount of coffee beans can be controlled by controlling the rotation speed of the rotary drum after the hot air treatment instead of adjusting the roasting speed of a large amount of coffee beans according to the intensity of the applied heat. To optimize thermal efficiency to roast coffee beans.

For example, the roasting speed of the coffee beans can be adjusted by lowering the rotation speed of the rotation motor 310, or the roasting speed of the coffee beans can be controlled by increasing the rotation speed of the rotation motor 310.

Meanwhile, the rotation speed of the rotation motor 310 may be relatively controlled according to changes in the internal temperature of the housing 100. That is, when the internal temperature of the housing 100 rises, the rotating speed of the rotating motor 310 is increased to prevent the coffee beans from burning. When the internal temperature of the housing 100 is lowered, So that the coffee beans are roasted sufficiently.

As described above, the coffee roaster according to the embodiment of the present invention optimizes the heat efficiency while keeping the inside temperature of the housing constant, thereby controlling the rotational speed of the rotary drum after hot air processing the inside of the housing to roast the coffee bean, It can be seen that the basic technical idea is to control the roasting speed of the coffee bean so that even non-skilled persons can roast the coffee bean stably. Therefore, many modifications may be made by those skilled in the art without departing from the scope and spirit of the present invention.
