Description

[Detailed description of the invention] (Field of industrial application) This invention can be used as a container for storing raw coffee beans (coffee beans before roasting), and allows coffee beans to be roasted easily and quickly at home. Regarding the coffee bean roaster that can be used.

(Prior art and its problems) Conventionally, there is a coffee bean roaster for general household use, such as the one disclosed in Japanese Utility Model Publication No. 57-45839, and the coffee beans roasted with this roaster are commercially available. I'm using what's available.

However, commercially available coffee beans are not properly managed at the time of sale or after purchase.
The quality of the coffee beans is not constant, and when roasting them with the above-mentioned home roaster, the quality of the coffee beans varies, so it is difficult to roast to your preference, and the structure of this roaster is Not only is it complicated and expensive, but it also requires time and effort to clean it after use. Therefore, even if coffee beans were roasted using a home roaster, it was not possible to roast them uniformly.

Therefore, the present invention was developed in view of the above, and an object of the present invention is to provide a coffee bean roaster that can easily roast coffee beans to a desired roasting state at home.

(Means and effects for solving the problems) The coffee bean roaster according to this invention consists of a tray portion for storing raw coffee beans, and a lid portion that expands into a hemispherical shape when heated. The tray part and the lid part are used as a storage container to maintain the desired quality of coffee beans before roasting. The raw coffee beans can be roasted by evenly rolling them through the rows.

(Example) An example of this invention is shown in Figures 1 to 6.
This will be explained based on the diagram. In the figure, reference numeral 1 denotes a dish part, in which raw coffee beans 3 are stored in an almost airtight state together with a lid part 2. This dish part 1 is a bread-shaped part consisting of a bottom part 1a made of a circular plate and an inclined part 1b which stands up in an inclined manner from the outer periphery of the bottom part 1a, and the raw coffee beans 3 are stored inside the dish part 1. The bottom portion 1a is provided with a protrusion 4. The protruding strip 4 includes a cylindrical protrusion 4a formed at the center of the bottom 1a, and radial protrusions 4b radially extending from the cylindrical protrusion 4a toward the outer circumference of the bottom 1a. Ten radial protrusions 4b are provided with a gap of about 36 degrees, and the bottom portions 1a between the radial protrusions 4b are formed flat.

Approximately 10 grams of raw coffee beans 3 are stored in the bottom portion 1a between the radial projections 4b as shown in the figure. That is, the amount of coffee beans for one person is contained between the radial projections 4b of the bottom portion 1a.

The inclined part 1b of the dish part 1 has an upper lid part 2.
The ends of the lid part 2 are connected together, and the inner end of the lid part 2 is joined to the inside of the inclined part 1b, and this joined part moves upward with respect to the upper edge of the inclined part 1b during roasting. The entire lid portion 2 is configured to expand into a hemispherical shape. Furthermore, an opening 5 that opens during roasting is formed approximately in the center of the lid 2.
The opening 5 is closed with a lid 6 before roasting, and the opening 5 is opened by pulling a knob 7 attached to the lid 6 during roasting.

Further, a handle 8 is attached to the upper edge of the inclined portion 1b of the dish portion 1.

In the coffee bean roaster having the above configuration, in order to roast the raw coffee beans 3 stored therein, the
Under the storage and sales conditions shown in the figure, hold the handle 8, turn on the gas stove to high heat, and place it on the fire at a distance of about 2 cm from the flame, and while constantly shaking the tray 1 back and forth and left and right, make sure that the coffee beans 3 inside are evenly distributed in the tray. Roast by rolling in part 1. At this time, the raw coffee beans 3 hit the radial protrusions 4b of the bottom 1a, promoting stirring and roasting them uniformly. In this way, 5 to 7
When the portion is roasted, the inside is heated and the internal air expands, so the lid part 2 expands into a hemispherical shape, and
The crackling sound of three raw coffee beans begins. At this point, lift the knob 7 and pull the lid 6 to open the opening 5. While looking inside through the opening 5, you can choose the desired roasting method, such as light roasting or strong roasting (dark roasting), depending on the color, aroma, etc. Furthermore, the generated smoke is discharged from the opening 5 of the lid 2, thereby preventing the smoke odor from adhering to the beans and spoiling their flavor. Further, when stirring the green coffee beans 3, the lid portion 2 expands upward into a hemispherical shape, so the green coffee beans 3 do not fly out. After the raw coffee beans 3 are roasted to a desired state, they are cooled by, for example, blowing cold air. Since the amount for one person is stored between the radial protrusions 4b of this dish portion 1, it can be used for measuring, so that coffee beans for each person can be taken out.

After roasting, the taste of coffee beans 3 will settle down if you leave it for a day, and the shelf life is about 10 days, so please use it as appropriate.
You can take out the beans for the desired number of people, crush them, extract them, and drink them.

In addition, the above-mentioned dish part 1 and lid part 2 are formed of aluminum foil. Furthermore, although a case has been described in which radial protrusions are formed as protrusions on the dish portion 1, the protrusions are not limited to radial protrusions, and may be in the form of a lattice, for example.

(Effects) According to the present invention, coffee beans can be stored with a simple structure, and at the time of roasting, stirring of the coffee beans can be promoted by the protrusions on the dish, so that the coffee beans can be roasted uniformly.
