Description

Coffee Extractor {A DEVICE FOR EXTRACTING A COFFEE}

The present invention relates to a coffee maker equipped with a coffee bean roasting device,

In detail, the coffee beans accommodated in the main body are rotated while being moved up and down by the rotation of the stirring rotor, so that the roasting work is efficiently prevented from tangling during the roasting process. The present invention relates to a coffee extracting apparatus that allows to perform fresh coffee extraction while sequentially performing grinding and extraction.

In the case of a roasting method for heating green beans by heating means, a conventional general method has been used by a forced hot air method or a method of applying a separate stirring device to a chamber.

In this conventional method, the power supply is installed while stirring by installing a stirring device, but the raw beans are fixed while being inclined to one of the positions so that the raw beans are not completely stirred and the roasting is not uniformly mixed, and the beans are entangled together. I had a problem that can not be fried.

On the other hand, in the process of peeling the raw beans in the distributor, there was a disadvantage in that the beans and shells were mixed with the roasted beans as they could not be effectively separated from the beans and the shells were mixed with the roasted beans.

In addition, in the cooling system of the distributor, an additional cooling device was installed to be operated after distribution, and excessive noise problem was raised. As a result, the inside of the equipment was dusty due to the scattering of the bean shell by the rotation of the cooling motor. There was a problem of degradation, and the ground coffee powder was introduced into the interior to reduce the taste of the coffee. In addition, when the roasted beans are repeatedly rotated in the same place even without idling for a long time without using a separate cooling device, the roasted beans are tangled with each other, reducing the cooling efficiency was accompanied by a long cooling time.

On the other hand, in the case of the crushing device, the cutter and the crushing part may not be easily cleaned after being crushed several times in the crushing cutter. Therefore, the whole machine or the crusher or the crushing part must be completely disassembled.

The present invention has been researched and developed to solve these various problems.

The present invention is to solve the various problems described above, the bean does not stay in one place by the plate-shaped distribution rotor that rotates along the inner shape of the cylindrical distributor, uniform by the heating means in the state of continuous rotation transfer While the roasting part is formed on one side of the distributor, the opening and closing part of the distribution box adopts a part of the distribution box in a completely open and closed manner so that the beans discharged are not caught in the opening and closing door, and the roasted beans are prevented from escaping into the grinder. It is a technical problem of the present invention to form a plurality of bean shell discharge holes in the lower side of the outer wall of the soybean shell to be efficiently discharged by the roasting rotor is rotated generated during the roasting process.

Another technical problem of the present invention is to maximize the displacement displacement of raw beans by rotating the plate rotor rotated in the distribution box,

The hot-distributed hot soybeans can be obtained with a little idling operation without using a separate blower, and the cooling of fresh soybeans with only a short time of operation even when using a blower as a cooling means. Effects can be obtained and the heated air forms a plurality of vents on the outer wall of the main body of the device so that the natural cooling effect is exerted so that various problems such as noise and vibration caused by long time blowing are naturally solved.

Another technical problem of the present invention is to allow the front and rear parts of the grinder to be separated from each other to easily clean the inside while separating the grinder from the front or side easily. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
