Abstract

(57) [Summary] [Purpose] Not only freshly ground, but also roasting, which is the pre-stage of coffee bean crushing, can be easily done by ordinary households.
An object of the present invention is to provide a coffee mill capable of obtaining freshly roasted coffee beans in a state in which neither taste nor flavor is impaired. [Structure] A mill container is formed of a ceramic heater, and electricity can be applied to the mill container so that roasting and crushing of coffee beans can be performed by the same device.

[Industrial applications]

 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coffee mill, and more particularly, to a coffee mill containing coffee beans and a coffee mill provided with a rotary blade disposed at the lower portion of the coffee mill.

[0002]

[Prior Art]

 Roasting coffee beans is an important process that influences the taste of coffee, and there have been several coffee bean roasters used to roast coffee beans.

As shown in FIG. 2, a conventional coffee bean roaster 15 includes a roaster main body 12 including a roasting furnace 10 and a combustion chamber 11, a burner 13 as a heating source, and a blower. 14 and 14 are attached.

In the roasting machine 15 having the above-described structure, the hot air heated by the burner 13 is blown into the roasting furnace 10 by the blowing device 14 and is fed into the roasting furnace 10 from the coffee bean charging port 16. Roast the green coffee beans 18. The roasted coffee beans are taken out from the coffee bean take-out port 17 and provided to a coffee mill for grinding the coffee beans.

This method is mainly used for industrial purposes specialized in roasting.

Further, as a simple method of roasting, a direct fire method of roasting green coffee beans in a gas pot or the like is well known.

[0007]

[Problems to be solved by the device]

 However, after roasting coffee beans roasted by the above-mentioned method, after roasting, the coarse fibers of the beans become carbonized and easily dissolved in water, so that moisture in the air is absorbed more and more. There was a problem that the oxidization progressed and both the scent and the flavor decreased.

The present invention has been devised in view of the above problems, and an object thereof is to provide a coffee mill capable of treating roasting and crushing of coffee beans with the same device.

[0009]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, a coffee mill according to the present invention is a coffee mill having a mill container for storing coffee beans and a rotary blade arranged below the mill container. It is characterized in that it is formed by a ceramic heater and is capable of conducting electricity to the mill container.

[0010]

[Action]

 According to the coffee mill having the above structure, since the mill container is formed by the ceramic heater, the green coffee beans are further roasted in the mill container and continuously roasted in the same mill container. Coffee beans will be crushed.

[0011]

【Example】

 An embodiment of a coffee mill according to the present invention will be described below with reference to the drawings.

As shown in FIG. 1, a coffee machine 20 according to this embodiment has a main body upper portion 20A in which a mill container 21 formed of a ceramic heater is enclosed and surrounded by a heat insulating material 22. A lid is arranged above 21. A rotary blade 23, which is directly connected to a motor 24, is arranged below the mill container 21.

A power cord 25 is provided on the rear surface of the lower portion 20B of the coffee mill 20, and a membrane key 26 is provided on the front surface. A control board 27 connected to the membrane key 26 is disposed on the inner surface of the lower part 20B of the main body. The control board 27 is connected to the mill container 21 and the motor 24, and the rotation speeds of the ceramic heater and the motor 24 are changed. It is controlled.

In the coffee mill 20 having the above-described structure, after the green coffee beans 18 are put into the mill container 21, the membrane key 26 is operated to operate the control board 27 to operate the mill container 21 which is a ceramic heater. Is energized and heating and roasting is performed. At this time, it is advisable to rotate the rotary blade 23 at a low speed so that the coffee beans cannot be unevenly roasted and roast the coffee beans while stirring.

When the roasting of the coffee beans is completed, the rotary blade 23 starts rotating at high speed to crush the roasted coffee beans.

By injecting hot water into coffee beans crushed by the above method, it is possible to taste delicious coffee excellent in aroma and flavor.

[0017]

[Effect of the device]

 As is clear from the above description, in the coffee mill according to the present invention, since the mill container is formed of a ceramic heater and the mill container can be energized, coffee beans can be produced by the same device. Roasting and crushing can be performed, and at home, not only freshly ground coffee, but also freshly roasted and delicious coffee can be tasted.
