Description

Dust Collection System For Cafe {Dust Collection System For Cafe}

The present invention relates to a dust collecting system for a cafe, and more particularly, to a dust collecting system for a cafe implemented to effectively remove smoke and dust generated during a roasting process of green coffee beans.

Coffee is marketed in the form of coffee beans, ground coffee beans, and instant coffee, and among them, coffee beans are the most used because of their excellent taste and aroma.

In particular, coffee beans that are roasted and packaged for sale in Europe are purchased and ground with a grinding device at home to drink coffee with a fresher taste and aroma. In some cases, fresh coffee beans are directly roasted and then ground to drink do.

In Korea, coffee beans with various tastes and scents are imported depending on the cultivation area and seeds and then roasted directly or imported and sold in a roasted state.

The coffee roaster used to roast coffee beans in this way is a direct fire method that roasts coffee by receiving a heat source directly from the drum, an indirect heat method that burns coffee by indirect heat by constructing a blocking plate between the heat source and the drum, and a heat source There is a hot air method in which the coffee is roasted by heating the drum using heated air.

Of these, in the case of the direct fire method, a heat source such as a burner is directly transmitted to the drum in which the coffee is accommodated, and in the case of the indirect heat method or hot air method, roasting is performed by indirect heat or hot air transmitted to the drum. .

On the other hand, the above-mentioned background art is technical information that the inventor possessed for the derivation of the present invention or acquired in the process of derivation of the present invention, and it cannot be said that it is necessarily a known technique disclosed to the general public before the filing of the present invention. .
